7.1、資料庫

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');
           

7.2、基本環境搭建

完整項目結構：

1、建立Maven項目，SSMproject，添加Web支援。

2、導入相關依賴

3、建立基本結構和架構配置

• com.zcy.pojo
• com.zcy.dao
• com.zcy.service
• com.zcy.controller
• mybatis-config.xml

  <?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>
      
  </configuration>
             

• spring-dao.xml（spring整合dao）
• spring-service.xml（spring整合dao）
• spring-controller.xml（spring整合dao）

• applicationContext.xml（将dao、service、controller合并到同一個檔案）

  上面四個的配置相似

  <?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/springbeans.xsd">
      
  </beans>
             

7.3、MaBatis層

MyBatis層主要操作資料庫，旗下有Dao層（直接操作資料）的接口+對應mapper以及Service層的（調用Dao層） 接口+實作類。

1、資料庫配置檔案 database.properties

#如果使用MySQL8.0以上，需要在url配置時區：&serverTimezone=Asia/Shanghai
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=false&useUnicode=true&characterEncoding=utf8&serverTimezone=Asia/Shanghai
jdbc.username=root
jdbc.password=123456
           

2、IDEA連接配接資料庫（注意Advanced裡配置serverTimezone=Asia/Shanghai）

3、編寫MyBatis的核心配置檔案（mybatis-config.xml）

<?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>
	<!-- 資料源交給Spring連接配接，這裡就不用配置了  -->
    <!-- 别名 -->
    <typeAliases>
        <package name="com.zcy.pojo"/>
    </typeAliases>
    <!-- 注冊Mapper -->
    <mappers>
        <mapper class="com.zcy.dao.BooksMapper"/>
    </mappers>

</configuration>
           

4、編寫資料庫對應的實體類（com.zcy.pojo.Books）

//這裡使用了lombok插件
package com.zcy.pojo;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Books {
    private int bookID;
    private String bookName;
    private int bookCounts;
    private String detail;
}
           

5、編寫Dao層的Mapper接口

package com.zcy.dao;

import com.zcy.pojo.Books;
import org.apache.ibatis.annotations.Param;

import java.util.List;

public interface BookMapper {
    //增加一本書
    int addBook(Books books);

    //删除一本書
    int deleteBookByID(@Param("bookID") int id);

    //更新一本書
    int updateBook(Books books);

    //查詢一本書
    Books queryBookByID(@Param("bookID") int id);

    //查詢全部書
    List<Books> queryAllBook();

    //查詢一類書
    List<Books> queryBookByName(@Param("bookName") String bookName);
}
           

6、編寫接口對應的BooksMapper.xml。（要有前面導入的MyBatis包才有效）

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.zcy.dao.BookMapper">
    <!-- 增加一本書（bookID是自增，可以省略）-->
    <insert id="addBook" parameterType="books">
        insert into books (bookName,bookCounts,detail)
         values (#{bookName},#{bookCounts},#{detail});
    </insert>

    <!-- 删除一本書（int的别名是_int，Integer的别名是int，自動裝箱）-->
    <delete id="deleteBookByID" parameterType="int">
        delete from books where bookID = #{bookID}
    </delete>

    <!-- 更新一本書-->
    <update id="updateBook" parameterType="books">
        update books
        set bookName=#{bookName},bookCounts=#{bookCounts},detail=#{detail}
        where bookID=#{bookID}
    </update>

    <!-- 查詢一本書-->
    <select id="queryBookByID" parameterType="int" resultType="books">
        select * from books where bookID=#{bookID}
    </select>

    <!-- 查詢全部書-->
    <select id="queryAllBook" resultType="books">
        select * from books
    </select>

    <!-- 查詢一類書-->
    <select id="queryBookByName" parameterType="string" resultType="books">
        select * from books where bookName = #{bookName}
    </select>

</mapper>
           

7、編寫Service層的接口和實作類

接口：

package com.zcy.service;

import com.zcy.pojo.Books;

import java.util.List;

public interface BookService {
    //增加一本書
    int addBook(Books books);

    //删除一本書
    int deleteBookByID(int id);

    //更新一本書
    int updateBook(Books books);

    //查詢一本書
    Books queryBookByID(int id);

    //查詢全部書
    List<Books> queryAllBook();

    //查詢一類書
    List<Books> queryBookByName(String bookName);
}
           

實作類：

package com.zcy.service;

import com.zcy.dao.BookMapper;
import com.zcy.pojo.Books;

import java.util.List;

public class BookServiceImpl implements BookService {
    //Service層隻需調用DAO層，要有set方法才能注入
    private BookMapper bookMapper;
    public void setBookMapper(BookMapper bookMapper) {
        this.bookMapper = bookMapper;
    }


    public int addBook(Books books) {
        return bookMapper.addBook(books);
    }

    public int deleteBookByID(int id) {
        return bookMapper.deleteBookByID(id);
    }

    public int updateBook(Books books) {
        return bookMapper.updateBook(books);
    }

    public Books queryBookByID(int id) {
        return bookMapper.queryBookByID(id);
    }

    public List<Books> queryAllBook() {
        return bookMapper.queryAllBook()   ;
    }

    public List<Books> queryBookByName(String bookName) {
        return bookMapper.queryBookByName(bookName);
    }
}
           

7.4、Spring層

1、配置Spring來整合MyBatis層的Dao接口、mapper.xml以及Service層的接口、實作類。這裡的資料源使用C3P0（資料源可以自己選，前面用的是Spring自帶的資料源）。

2、編寫相關配置檔案spring-dao.xml ，将MyBatis層下的Dao層整合進來。

建議對比一下之前Spring學習中整合MyBatis的配置檔案。

<?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
        https://www.springframework.org/schema/context/spring-context.xsd">

    <!-- 配置整合MyBatis Dao -->
    <!-- 1. 關聯資料庫配置檔案database.properties  -->
    <context:property-placeholder location="classpath:database.properties"/>

    <!-- 2. 資料庫連接配接池（代替了mybatis-config.xml的environment）
            c3p0(自動化、可自動加載配置檔案并設定到對象中)、dbcp(半自動化、不能自動連接配接)
            之前Spring項目中用的是自帶的 DriverManagerDataSource
        -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <!-- 配置連接配接池屬性(不同資料源的屬性名稱不同) -->
        <property name="driverClass" value="${jdbc.driver}"/>
        <property name="jdbcUrl" value="${jdbc.url}"/>
        <property name="user" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>

        <!-- c3p0連接配接池的私有屬性 -->
        <!-- 最大/小連接配接數量 -->
        <property name="maxPoolSize" value="30"/>
        <property name="minPoolSize" value="10"/>
        <!-- 關閉連接配接後不自動commit -->
        <property name="autoCommitOnClose" value="false"/>
        <!-- 擷取連接配接逾時時間（10秒） -->
        <property name="checkoutTimeout" value="10000"/>
        <!-- 當擷取連接配接失敗重試次數 -->
        <property name="acquireRetryAttempts" value="2"/>
    </bean>

    <!-- 3. 配置sqlSessionFactoryBean（用于生成SqlSession的） -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 注入資料源 -->
        <property name="dataSource" ref="dataSource"/>
        <!-- 關聯MyBatis核心配置檔案 -->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
    </bean>

    <!-- 4. 掃描Dao接口包，可以動态實作Dao接口注入到Spring容器。
            在Spring項目中，我們使用的是SqlSessionTemplate來手動注入，
            或者繼承SqlSessionDaoSupport來自動注入。-->
    <!-- 具體解釋：https://www.cnblogs.com/jpfss/p/7799806.html   -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!-- 注入sqlSessionFactory -->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        <!-- 給出需要掃描的包  -->
        <property name="basePackage" value="com.zcy.dao"/>
    </bean>
</beans>
           

3、編寫相關配置檔案spring-service.xml ，将MyBatis層下的service層整合進來。

<?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
        https://www.springframework.org/schema/context/spring-context.xsd">

    <!-- 1. 掃描service層的相關bean -->
    <context:component-scan base-package="com.zcy.service"/>

    <!-- 2. 将BookServiceImpl注入到容器(配置或注解都可以) -->
    <bean id="BookServiceImpl" class="com.zcy.service.BookServiceImpl">
        <!-- 這裡ref能引用到bookMapper，因為spring-dao.xml中配置動态掃描 -->
        <property name="bookMapper" ref="bookMapper"/>
    </bean>

    <!-- 3. 配置事務管理器  -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!-- 注入資料庫連接配接池 -->
        <property name="dataSource" ref="dataSource"/>
    </bean>

    <!-- 4. 可加入AOP事務支援（切入的地方） -->
</beans>
           

7.5、SpringMVC層

SpringMVC主要是Controller層。

1、web.xml 需要配置DispatcherServlet和亂碼過濾器

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">
    <!-- 配置DispatcherServlet -->
    <servlet>
        <servlet-name>DispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <!-- 注意：這裡要用總的Spring配置檔案 -->
            <param-value>classpath:applicationContext.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>DispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <!-- 用Spring自帶的亂碼過濾器 -->
    <filter>
        <filter-name>CharacterEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>utf-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>CharacterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!-- session過期時間 15分鐘    -->
    <session-config>
        <session-timeout>15</session-timeout>
    </session-config>
</web-app>
           

2、配置spring-mvc.xml

<?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"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        https://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/mvc
        https://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <!-- 配置SpringMVC    -->
    <!-- 1. 掃描包  -->
    <context:component-scan base-package="com.zcy.controller"/>
    <!-- 2. 開啟注解驅動   -->
    <mvc:annotation-driven/>
    <!-- 3. 靜态資源預設Servlet配置  -->
    <mvc:default-servlet-handler/>

    <!-- 4. 配置JSP的視圖解析器  -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
</beans>
           

3、配置applicationContext.xml，來整合spring-dao、spring-service、spring-mvc

<?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">
    <import resource="spring-dao.xml"/>
    <import resource="spring-service.xml"/>
    <import resource="spring-mvc.xml"/>
</beans>
           

至此，架構已經搭建完成！接下來編寫SpringMVC的Controller以及視圖層（用了bootstrap美化，JSP中隻需要明白通過$擷取後端值就行）。

1、BookController.java

package com.zcy.controller;

import com.zcy.pojo.Books;
import com.zcy.service.BookService;
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.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;

import java.util.List;

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

    //跳轉到添加一本書頁面
    @RequestMapping("/toAddBook")
    public String toAddBook(){
        return "addBook";
    }

    //查詢全部書
    @RequestMapping("/allBook")
    public String queryAllBook(Model model){
        List<Books> list = bookService.queryAllBook();
        model.addAttribute("list", list);
        return "allBook";
    }

    //添加一本書(參數是前端傳遞過來的)
    @PostMapping("/addBook")
    public String addBook(Books books){
        bookService.addBook(books);
        return "redirect:/book/allBook";
    }

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

    //修改一本書
    @PostMapping("/updateBook")
    public String updateBook(Books books){
        bookService.updateBook(books);
        return "redirect:/book/allBook";
    }

    //删除一本書
    @RequestMapping("/deleteBook/{bookID}")
    public String deleteBook(@PathVariable("bookID") int id){
        bookService.deleteBookByID(id);
        return "redirect:/book/allBook";
    }

    //查詢一類書
    @PostMapping("/queryBookByName")
    public String queryBookByName(String bookName, Model model){
        List<Books> list = bookService.queryBookByName(bookName);
        model.addAttribute("list", list);
        System.out.println("queryBookByName——》"+list);
        if (list==null || list.isEmpty())
            model.addAttribute("message", "書籍不存在");
        return "allBook";
    }
}
           

2、首頁：index.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<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;
