SSM架構的整合步驟以及案例示範，我已經總結完了。

希望大家，除了一些特别固定的配置檔案外，有一個簡單的需求，都可以做到手動配置實作。這樣對大家對SSM架構會有進一步的了解，多配置幾遍會更加熟悉這個流程。

就這個簡單的整合，我已經在Eclipse上和Idea上都配過不止一遍，每一次都會有不同的問題，都會有不同的發現，隻有多練習才能知道哪裡有缺陷，勸大家不要眼高手低。。

覺得對你有幫助的，希望多多支援部落客，記得點贊關注哦~~

一、整合SSM架構案例

1、環境要求：

環境：

IDEA
MySQL 5.7
Tomcat 8.5
Maven 3.6.1

要求：

需要熟練掌握MySQL資料庫，Spring，JavaWeb及MyBatis知識，簡單的前端知識；

2、資料庫環境

建立一個存放書籍資料的資料庫表

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');

3、基本環境搭建

建立一Maven項目！ ssmbuild ，添加web的支援
導入相關的pom依賴！

Maven資源過濾設定(已在上邊完整pom檔案中配置，這裡再貼一下)

<!-- 靜态資源導出問題 -->

        <resources>
            <resource>

                <filtering>false</filtering>
            </resource>
        </resources>
    </build>

建立基本結構和配置架構！

com.biubiubiu.pojo
com.biubiubiu.dao
com.biubiubiu.service
com.biubiubiu.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>

applicationContext.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"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd">

</beans>

4、Mybatis層編寫

1.資料庫配置檔案 database.properties

jdbc.driver=com.mysql.jdbc.Driver
#如果是mysql8.0以上的版本，需要增加時區設定&serverTimeZone=Asia/Shanghai
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=123456

2.IDEA關聯資料庫
3.編寫MyBatis的核心配置檔案

<?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>

	    <!--引入日志，log4j  有時候很煩。。我這裡就關了。。-->
<!--
    <settings>
        <setting name="logImpl" value="STDOUT_LOGGING"/>
    </settings>
-->

    <!-- 配置資料源 -->
    <typeAliases>
        <package name="com.biubiubiu.pojo"/>
    </typeAliases>

    <mappers>
        <mapper class="com.biubiubiu.dao.BookMapper"/>
    </mappers>

</configuration>

4.編寫資料庫對應的實體類 com.biubiubiu.pojo.Books

使用lombok插件！

package com.biubiubiu.pojo;

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

/**
 * @author biubiubiu
 */
@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.biubiubiu.dao;

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

import java.util.List;

/**
 * @author biubiubiu
 */
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);

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

    //通過書名查找書籍
    Books queryBookByName(@Param("bookName") String bookName);

}

6.編寫接口對應的 Mapper.xml 檔案。需要導入MyBatis的包；

<?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="com.biubiubiu.dao.BookMapper">

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

    <!--根據id删除一個Book-->
    <delete id="deleteBookById" parameterType="int">
        delete from ssmbuild.books where bookID=#{bookID};
    </delete>

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

    <!--根據id查詢,傳回一個Book-->
    <select id="queryBookById" resultType="Books">
		select * from ssmbuild.books
		where bookID=#{bookID};
	</select>

    <!--查詢全部Book-->
    <select id="queryAllBook" resultType="Books">
		select * from ssmbuild.books;
	</select>

    <!--搜尋Book根據名稱-->
    <select id="queryBookByName" 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.biubiubiu.service;

import com.biubiubiu.pojo.Books;

import java.util.List;

/**
 * @author biubiubiu
 */
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);

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

    //通過書名查找書籍
    Books queryBookByName(String bookName);

}

實作類：

package com.biubiubiu.service;

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

import java.util.List;

/**
 * @author biubiubiu
 */
public class BookServiceImpl implements BookService{
    //service調用dao層：組合dao
    private BookMapper bookMapper;
    public void setBookMapper(BookMapper bookMapper) {
        this.bookMapper = bookMapper;
    }


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

    @Override
    public int deleteBookById(int id) {
        return bookMapper.deleteBookById(id);
    }

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

    @Override
    public Books queryBookById(int id) {
        return bookMapper.queryBookById(id);
    }

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

    @Override
    public Books queryBookByName(String bookName) {
        return bookMapper.queryBookByName(bookName);
    }
}

OK，到此，底層需求操作編寫完畢！

5、Spring層

配置Spring整合MyBatis，我們這裡資料源使用c3p0連接配接池；

我們去編寫Spring整合Mybatis的相關的配置檔案；

5.1、 spring-dao.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"
       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">

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


    <!-- 2.連接配接池 :
        dbcp:半自動化操作，不能自動連接配接
        c3p0：自動化操作(自動化的加載配置檔案，并且可以自動設定到對象中)
        Druid：阿裡的，公司常用
        hikari:springboot2.0自帶的
    -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <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:大小 -->
        <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 -->
        <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.sqlSessionFactory -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 注入資料庫連接配接池 -->
        <property name="dataSource" ref="dataSource"/>
        <!-- 配置綁定MyBaties全局配置檔案:mybatis-config.xml -->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>

        <!--不知道為什麼，在eclipse中沒有配置這個就沒錯，但是在idea中就會找不到xml。。-->
        <property name="mapperLocations" value="classpath:com/biubiubiu/dao/*.xml"/>
    </bean>


    <!-- 4.配置Dao接口掃描包，動态的實作了Dao接口可以注入到Spring容器中(value與上邊的id對應) -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!-- 注入sqlSessionFactory -->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        <!-- 掃描要掃描的Dao包 -->
        <property name="basePackage" value="com.biubiubiu.dao"/>
    </bean>




</beans>

Spring整合service層

5.2、spring-service.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:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       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
    			http://www.springframework.org/schema/aop
    			http://www.springframework.org/schema/aop/spring-aop.xsd
    			http://www.springframework.org/schema/tx
    			http://www.springframework.org/schema/tx/spring-tx.xsd">

    <!-- 1.掃描service相關的包 -->
    <context:component-scan base-package="com.biubiubiu.service"/>

    <!-- 2.将ServiceImpl注入到IOC容器中 （依賴注入）-->
    <!--将我們的所有業務類，注入到spring，可以通過配置，或者注解實作-->
    <!--完全可以使用注解替換：@Service、@Autowired、@Qualifier或#Resource-->
    <bean id="BookServiceImpl" class="com.biubiubiu.service.BookServiceImpl">
        <property name="bookMapper" ref="bookMapper"/>
    </bean>

    <!-- 3.配置事務管理器:聲明式事務配置 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!-- 注入資料源 -->
        <property name="dataSource" ref="dataSource" />
    </bean>

    <!-- 4.AOP事務支援！！ -->
    <!-- 結合AOP實作事務的織入 -->
    <!-- 配置事務通知： -->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <!-- 給那些方法配置事務 -->
        <!-- 配置事務的傳播特性：new propagetion -->
        <tx:attributes>
            <tx:method name="*" propagation="REQUIRED"/>
        </tx:attributes>
    </tx:advice>

    <!-- 配置事務切入：橫切 -->
    <aop:config>
        <aop:pointcut id="txPointCut" expression="execution(* com.biubiubiu.dao.*.*(..))"/>
        <aop:advisor advice-ref="txAdvice" pointcut-ref="txPointCut"/>
    </aop:config>




</beans>

Spring層搞定！再次了解一下，Spring就是一個大雜燴，一個容器！對吧！

6、SpringMVC層

6.1、web.xml

<?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">

    <!-- 添加對springmvc的支援 -->
    <!-- DispatcherServlet -->
    <servlet>
        <servlet-name>springMVC</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:applicationContext.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>springMVC</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <!-- 編碼過濾器 -->
    <filter>
        <filter-name>encodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>

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

    <!-- 一般還有有個Session的過期時間 -->
    <session-config>
        <session-timeout>15</session-timeout>
    </session-config>

</web-app>

6.2、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"

6.3、Spring配置整合檔案，applicationContext.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"
       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>

配置檔案，暫時結束！

7、Controller 和視圖層編寫

7.1、編寫過程

BookController 類編寫，方法一：查詢全部書籍

@Autowired
    @Qualifier("BookServiceImpl")
    private BookService bookService;

    //查詢全部的書籍，并且傳回到一個書籍展示頁面allBook
    @RequestMapping("/allBook")
    public String list(Model model) {
        List<Books> list = bookService.queryAllBook();
        model.addAttribute("list",list);
        return "allBook";
    }

編寫首頁 index.jsp

<%@ 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>

        return "addBook";
    }

    //添加書籍的請求
    @RequestMapping("/addBook")
    public String addBook(Books books) {
        bookService.addBook(books);
        //重定向到上邊的@RequestMapping("/allBook")請求，實作請求複用
        return "redirect:/book/allBook";
    }

添加書籍頁面：addBook.jsp

    public String toUpdatePaper(int id, Model model) {
        Books books = bookService.queryBookById(id);
        model.addAttribute("books", books);
        return "updateBook";
    }

    //修改書籍的請求
