概述

通過對資料庫中一張表的CRUD，将相應的操作結果渲染到頁面上。

如果想檢視Spring Boot架構的同等規模的項目，可參考此篇部落格​​​Spring Boot項目執行個體——簡易版商城管理系統​​ 由于廣大讀者要求源碼，作者通過這篇部落格還原了項目（當然有一些隐藏的坑），然後将該項目上傳到了Gitee，在末尾的後記部分有源碼位址，讀者可參考。

準備

• 環境：

• IDEA
• MySQL 5.7.19
• Tomcat 9
• Maven 3.6

• 要求：

• 掌握MySQL資料庫
• 掌握Spring，
• 掌握SpringMVC
• 掌握MyBatis知識
• 掌握簡單的前端知識

實作

1.搭建資料庫

1. 建立一個存放書籍資料的資料庫（ssmbuild），并在該資料庫中建立一個名為books的表，代碼如下：

CREATE DATABASE `ssmbuild`;

USE `ssmbuild`;

DROP TABLE IF EXISTS `books`;

CREATE TABLE `books` (
  `bookID` INT(10) NOT NULL AUTO_INCREMENT COMMENT '書id',
  `bookName` VARCHAR(100) NOT NULL COMMENT '書名',
  `bookCounts` INT(11) NOT NULL COMMENT '數量',
  `detail` VARCHAR(200) NOT NULL COMMENT '描述',
  KEY `bookID` (`bookID`)
) ENGINE=INNODB DEFAULT CHARSET=utf8

INSERT  INTO `books`(`bookID`,`bookName`,`bookCounts`,`detail`)VALUES 
(1,'Java',1,'從入門到放棄'),
(2,'MySQL',10,'從删庫到跑路'),
(3,'Linux',5,'從進門到進牢');      

1. 寫好資料庫的配置檔案database.properties，該檔案可以放在resources目錄下，代碼如下：

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=123456      

1. 在Maven中導入資料庫連接配接所需要的驅動包（mysql-connector），代碼如下：

<dependency>
      <groupId>mysql</groupId>
      <artifactId>mysql-connector-java</artifactId>
      <version>5.1.47</version>
    </dependency>      

2.實作pojo層

在項目的java目錄下建立pojo包，因為資料庫中隻有一個表，是以隻需要編寫一個實體類Book即可，代碼如下所示：

package pojo;

public class Book {

    private int bookID;
    private String bookName;
    private int bookCounts;
    private String detail;

    public Book() {
    }

    public Book(int bookID, String bookName, int bookCounts, String detail) {
        this.bookID = bookID;
        this.bookName = bookName;
        this.bookCounts = bookCounts;
        this.detail = detail;
    }

    public int getBookID() {
        return bookID;
    }

    public void setBookID(int bookID) {
        this.bookID = bookID;
    }

    public String getBookName() {
        return bookName;
    }

    public void setBookName(String bookName) {
        this.bookName = bookName;
    }

    public int getBookCounts() {
        return bookCounts;
    }

    public void setBookCounts(int bookCounts) {
        this.bookCounts = bookCounts;
    }

    public String getDetail() {
        return detail;
    }

    public void setDetail(String detail) {
        this.detail = detail;
    }

    @Override
    public String toString() {
        return "Book{" +
                "bookID=" + bookID +
                ", bookName='" + bookName + '\'' +
                ", bookCounts=" + bookCounts +
                ", detail='" + detail + '\'' +
                '}';
    }
}      

3.實作dao層

1. 在項目的java目錄下建立dao包，編寫dao層接口BookDao即可，代碼如下所示：

package dao;

import org.apache.ibatis.annotations.Param;
import pojo.Book;

import java.util.List;

public interface BookDao {

    //增加一個Books
    int addBook(Book books);

    //根據id删除Books
    int deleteBookByID(@Param("bookID") int id);

    //更新Books
    int updateBook(Book books);

    //根據id查詢Book
    Book queryBookByID(@Param("bookID") int id);

    //檢視全部的Book
    List<Book> queryAllBook();

}      

1. 在Maven中導入Mybatis所需要的驅動包（mybatis），代碼如下：

<!-- MyBatis -->
    <dependency>
      <groupId>org.mybatis</groupId>
      <artifactId>mybatis</artifactId>
      <version>3.4.6</version>
    </dependency>      

1. 在dao包下編寫對應的映射檔案BookMapper.xml，代碼如下：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="dao.BookDao">
    <!--//增加一個Books-->
    <insert id="addBook" parameterType="Book">
        insert into ssmbuild.books(bookID , bookName, bookCounts, detail)
        values (#{bookID},#{bookName},#{bookCounts},#{detail})
    </insert>

    <!--//根據id删除Books-->
    <delete id="deleteBookByID" parameterType="int">
        delete from ssmbuild.books where bookID = #{bookID}
    </delete>

    <!--//更新Books-->
    <update id="updateBook" parameterType="Book">
        update ssmbuild.books
        set bookName = #{bookName} , bookCounts = #{bookCounts} ,detail = #{detail}
        where bookID = #{bookID}
    </update>

    <!--//根據id查詢Book-->
    <select id="queryBookByID" resultType="Book">
        select * from ssmbuild.books where bookID = #{bookID}
    </select>

    <!--//檢視全部的Book-->
    <select id="queryAllBook" resultType="Book">
        select * from ssmbuild.books
    </select>

</mapper>      

1. 在resources目錄下編寫Mybatis的配置檔案Mybatis-config.xml，用于配置别名，以及注冊映射檔案，代碼如下：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

    <typeAliases>
        <package name="pojo"/>
    </typeAliases>

    <mappers>
        <mapper resource="dao/BookMapper.xml"></mapper>
    </mappers>


</configuration>      

4.實作service層

1. 在項目的java目錄下建立service包，編寫service層接口BookService，代碼如下所示：

package service;

import org.apache.ibatis.annotations.Param;
import pojo.Book;

import java.util.List;

public interface BookService {

    //增加一個Books
    int addBook(Book books);

    //根據id删除Books
    int deleteBookByID( @Param("bookID") int id);

    //更新Books
    int updateBook(Book books);

    //根據id查詢Book
    Book queryBookByID(@Param("bookID") int id);

    //檢視全部的Book
    List<Book> queryAllBook();

}      

1. 在service包下編寫對應的實作類BookServiceImpl，代碼如下：

package service;

import dao.BookDao;
import pojo.Book;

import java.util.List;

public class BookServiceImpl implements BookService{

    // 組合
    private BookDao bookDao;

    public void setBookDao(BookDao bookDao) {
        this.bookDao = bookDao;
    }


    @Override
    public int addBook(Book books) {
        return bookDao.addBook(books);
    }

    @Override
    public int deleteBookByID(int id) {
        return bookDao.deleteBookByID(id);
    }

    @Override
    public int updateBook(Book books) {
        return bookDao.updateBook(books);
    }

    @Override
    public Book queryBookByID(int id) {
        return bookDao.queryBookByID(id);
    }

    @Override
    public List<Book> queryAllBook() {
        return bookDao.queryAllBook();
    }
}      

5.配置Spring整合dao層

1. 在本例中使用c3p0連接配接池，需要在Maven導入相關的包，代碼如下：

<!-- 資料庫連接配接池 -->
    <dependency>
      <groupId>com.mchange</groupId>
      <artifactId>c3p0</artifactId>
      <version>0.9.5.2</version>
    </dependency>
    <!-- mybatis-spring整合包 -->
    <dependency>
      <groupId>org.mybatis</groupId>
      <artifactId>mybatis-spring</artifactId>
      <version>1.3.1</version>
    </dependency>
    <!--Spring相關包-->
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-jdbc</artifactId>
      <version>4.3.24.RELEASE</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-webmvc</artifactId>
      <version>4.3.24.RELEASE</version>
    </dependency>      

1. 在resources目錄下建立spring檔案夾，并在該檔案夾中建立一個名為spring-dao.xml的配置檔案，用于讓Spring整合mybatis，代碼如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans.xsd

    </bean>

    <!--3.sqlSessionFactory-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <!--關聯mybatis-->

    </bean>

    <!--4.注冊dao層Bean-->
    <!--動态實作dao接口注入Spring容器中-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!--綁定sqlSessionFactory-->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        <!--掃描包-->
        <property name="basePackage" value="dao"/>
    </bean>

    <!--5.掃描包-->
    <context:component-scan base-package="dao"/>

</beans>      

6.配置Spring整合service層

在resources/spring檔案夾中建立一個名為spring-service.xml的配置檔案，用于讓Spring整合service層，代碼如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context.xsd">

    <!--1.掃描包-->
    <context:component-scan base-package="service"/>

    <!--2.手動配置bean-->
    <bean id="bookServiceImpl" class="service.BookServiceImpl">
        <property name="bookDao" ref="bookDao"/>
    </bean>

    <!--3.事務管理-->
    <bean class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!--資料源-->
        <property name="dataSource" ref="dataSource"/>
    </bean>


</beans>      

7.配置Spring整合Spring MVC

1. 修改webapp目錄下的web.xml檔案，代碼如下：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://java.sun.com/xml/ns/javaee"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
         http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         id="WebApp_ID" version="3.0">

  <!--1.DispatchServlet-->
  <servlet>
    <servlet-name>springmvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!--關聯Spring配置檔案-->
    <init-param>
      <param-name>contextConfigLocation</param-name>

    <url-pattern>/*</url-pattern>
  </filter-mapping>

</web-app>      

1. 在resources/spring檔案夾中建立一個名為spring-mvc.xml的配置檔案，用于讓Spring整合servlet層，代碼如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"

        <property name="suffix" value=".jsp"/>
    </bean>

</beans>      

1. 在目錄中建立一個名為filter的包，在包中建立名為GenericEncodingFilter的類，用于字元編碼過濾，代碼如下：

package filter;

import javax.servlet.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletRequestWrapper;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.UnsupportedEncodingException;
import java.util.Map;

/**
 * 解決get和post請求 全部亂碼的過濾器
 */
public class GenericEncodingFilter implements Filter {

    @Override
    public void destroy() {
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        //處理response的字元編碼
        HttpServletResponse myResponse=(HttpServletResponse) response;
        myResponse.setContentType("text/html;charset=UTF-8");

        // 轉型為與協定相關對象
        HttpServletRequest httpServletRequest = (HttpServletRequest) request;
        // 對request包裝增強
        HttpServletRequest myrequest = new MyRequest(httpServletRequest);

        chain.doFilter(myrequest, response);
    }

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
    }

}

//自定義request對象，HttpServletRequest的包裝類
class MyRequest extends HttpServletRequestWrapper {

    private HttpServletRequest request;
    //是否編碼的标記
    private boolean hasEncode;
    //定義一個可以傳入HttpServletRequest對象的構造函數，以便對其進行裝飾
    public MyRequest(HttpServletRequest request) {
        super(request);// super必須寫
        this.request = request;
    }

    // 對需要增強方法 進行覆寫
    @Override
    public Map getParameterMap() {
        // 先獲得請求方式
        String method = request.getMethod();
        if (method.equalsIgnoreCase("post")) {
            // post請求
            try {
                // 處理post亂碼
                request.setCharacterEncoding("utf-8");
                return request.getParameterMap();
            } catch (UnsupportedEncodingException e) {
                e.printStackTrace();
            }
        } else if (method.equalsIgnoreCase("get")) {
            // get請求
            Map<String, String[]> parameterMap = request.getParameterMap();
            if (!hasEncode) { // 確定get手動編碼邏輯隻運作一次
                for (String parameterName : parameterMap.keySet()) {
                    String[] values = parameterMap.get(parameterName);
                    if (values != null) {
                        for (int i = 0; i < values.length; i++) {
                            try {
                                // 處理get亂碼
                                values[i] = new String(values[i]
                                        .getBytes("ISO-8859-1"), "utf-8");
                            } catch (UnsupportedEncodingException e) {
                                e.printStackTrace();
                            }
                        }
                    }
                }
                hasEncode = true;
            }
            return parameterMap;
        }
        return super.getParameterMap();
    }

    //取一個值
    @Override
    public String getParameter(String name) {
        Map<String, String[]> parameterMap = getParameterMap();
        String[] values = parameterMap.get(name);
        if (values == null) {
            return null;
        }
        return values[0]; // 取回參數的第一個值
    }

    //取所有值
    @Override
    public String[] getParameterValues(String name) {
        Map<String, String[]> parameterMap = getParameterMap();
        String[] values = parameterMap.get(name);
        return values;
    }
}      

8.配置Spring整合檔案

1. 在resources中建立一個名為applicationContext.xml的配置檔案，用于整合上面的spring-dao.xml、spring-service.xml、spring-mvc.xml，代碼如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans.xsd">
    
    <!--整合Spring-->
    <import resource="classpath:spring/spring-dao.xml"/>
    <import resource="classpath:spring/spring-service.xml"/>
    <import resource="classpath:spring/spring-mvc.xml"/>

</beans>      

1. 在Maven導入jsp和servlet的包，代碼如下：

<dependency>
      <groupId>javax.servlet</groupId>
      <artifactId>javax.servlet-api</artifactId>
      <version>3.0.1</version>
      <scope>provided</scope>
    </dependency>
    <dependency>
      <groupId>javax.servlet.jsp</groupId>
      <artifactId>jsp-api</artifactId>
      <version>2.2</version>
      <scope>provided</scope>
    </dependency>
    <dependency>
      <groupId>javax.servlet</groupId>
      <artifactId>jstl</artifactId>
      <version>1.2</version>
    </dependency>      

9.實作controller層

在項目的java目錄下建立controller包，編寫控制器BookController，代碼如下所示：

package controller;

import org.apache.ibatis.annotations.Param;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import pojo.Book;
import service.BookService;

import java.util.List;

@Controller
@RequestMapping("/book")
public class BookController {
    @Autowired
    @Qualifier("bookServiceImpl")
    private BookService bookService;

    // 展示全部的書籍
    @RequestMapping("/allBook")
    public String list(Model model){
        List<Book> list = bookService.queryAllBook();
        model.addAttribute("list",list);
        return "allBook";
    }

    // 跳轉到新增書籍頁面
    @RequestMapping("/toAddBook")
    public String toAddBookPage(){
        return "addBook";
    }

    // 增加書籍
    @RequestMapping("/addBook")
    public String addBook(Book book){
        bookService.addBook(book);
        return "redirect:/book/allBook";
    }

    // 跳轉到修改書籍頁面
    @RequestMapping("/toUpdateBook")
    public String toUpdateBook(int id,Model model){
        Book book = bookService.queryBookByID(id);
        model.addAttribute("book",book);
        return "updateBook";
    }

    // 修改書籍
    @RequestMapping("/updateBook")
    public String updateBook(Book book,Model model){
        bookService.updateBook(book);
        // 更新最新的書籍
        Book book1 = bookService.queryBookByID(book.getBookID());
        model.addAttribute("books",book1);
        return "redirect:/book/allBook";
    }

    // 删除書籍，使用Restful風格
    @RequestMapping("/del/{bookID}")
    public String delete(@PathVariable("bookID") int id){
        bookService.deleteBookByID(id);
        return "redirect:/book/allBook";
    }
}      

10.實作view層

1. 編寫首頁index.jsp，用于進入檢視所有圖書的頁面，代碼如下：

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>
<!DOCTYPE HTML>
<html>
<head>
    <title>首頁</title>
    <style type="text/css">a {
            text-decoration: none;
            color: black;
            font-size: 18px;
        }
        h3 {
            width: 180px;
            height: 38px;
            margin: 100px auto;
            text-align: center;
            line-height: 38px;
            background: deepskyblue;
            border-radius: 4px;
        }</style>
</head>
<body>

<h3>
    <a href="${pageContext.request.contextPath}/book/allBook">點選進入清單頁</a>
</h3>
</body>
</html>      

1. 在WEB-INF目錄下建立jsp目錄，并在該目錄下編寫allBook.jsp，用于檢視所有圖書，代碼如下：

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>書籍清單</title>
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <!-- 引入 Bootstrap -->
    <link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>

<div class="container">

    <div class="row clearfix">
        <div class="col-md-12 column">
            <div class="page-header">
                <h1>
                    <small>書籍清單 —— 顯示所有書籍</small>
                </h1>
            </div>
        </div>
    </div>

    <div class="row">
        <div class="col-md-4 column">
            <a class="btn btn-primary" href="${pageContext.request.contextPath}/book/toAddBook">新增</a>
        </div>
    </div>

    <div class="row clearfix">
        <div class="col-md-12 column">
            <table class="table table-hover table-striped">
                <thead>
                <tr>
                    <th>書籍編号</th>
                    <th>書籍名字</th>
                    <th>書籍數量</th>
                    <th>書籍詳情</th>
                    <th>操作</th>
                </tr>
                </thead>

                <tbody>
                <c:forEach var="book" items="${requestScope.get('list')}">
                    <tr>
                        <td>${book.getBookID()}</td>
                        <td>${book.getBookName()}</td>
                        <td>${book.getBookCounts()}</td>
                        <td>${book.getDetail()}</td>
                        <td>
                            <a href="${pageContext.request.contextPath}/book/toUpdateBook?id=${book.getBookID()}">更改</a> |
                            <a href="${pageContext.request.contextPath}/book/del/${book.getBookID()}">删除</a>
                        </td>
                    </tr>
                </c:forEach>
                </tbody>
            </table>
        </div>
    </div>
</div>      

1. 在WEB-INF/jsp目錄下編寫addBook.jsp，用于添加圖書，代碼如下：

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>

<html>
<head>
    <title>新增書籍</title>
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <!-- 引入 Bootstrap -->
    <link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
<div class="container">

    <div class="row clearfix">
        <div class="col-md-12 column">
            <div class="page-header">
                <h1>
                    <small>新增書籍</small>
                </h1>
            </div>
        </div>
    </div>
    <form action="${pageContext.request.contextPath}/book/addBook" method="post">
        書籍名稱：<input type="text" name="bookName"><br><br><br>
        書籍數量：<input type="text" name="bookCounts"><br><br><br>
        書籍詳情：<input type="text" name="detail"><br><br><br>
        <input type="submit" value="添加">
    </form>

</div>      

1. 在WEB-INF/jsp目錄下編寫updateBook.jsp，用于添加圖書，代碼如下：

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>修改資訊</title>
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <!-- 引入 Bootstrap -->
    <link href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
<div class="container">

    <div class="row clearfix">
        <div class="col-md-12 column">
            <div class="page-header">
                <h1>
                    <small>修改資訊</small>
                </h1>
            </div>
        </div>
    </div>

    <form action="${pageContext.request.contextPath}/book/updateBook" method="post">
        <input type="hidden" name="bookID" value="${book.getBookID()}"/>
        書籍名稱：<input type="text" name="bookName" value="${book.getBookName()}"/>
        書籍數量：<input type="text" name="bookCounts" value="${book.getBookCounts()}"/>
        書籍詳情：<input type="text" name="detail" value="${book.getDetail() }"/>
        <input type="submit" value="送出"/>
    </form>

</div>      

11.運作前檢查

1. Maven的包導入應如下所示（注意添加build标簽中的resources标簽，該标簽用于讓Maven導入相關資源）：

1. 項目目錄如圖所示：

運作

配置好Tomcat運作環境後，即可開始運作，結果圖如下：

1. 首頁（index.jsp）



2. 顯示全部書籍（allBook.jsp）



3. 增加書籍頁面（addBook.jsp）



4. 修改書籍頁面（updateBook.jsp）

後記
