第一章：搭建整合环境

第二章：Spring框架代码的编写

1.搭建和测试Spring的开发环境

2.编写测试方法，进行测试

第三章：Spring整合SpringMVC框架

1.搭建和测试SpringMVC的开发环境

2. Spring整合SpringMVC的框架

第四章：Spring整合MyBatis框架

1. 搭建和测试MyBatis的环境

2.Spring整合MyBatis框架

        SSM（Spring + Spring MVC + MyBatis）框架整合是一个常见的 Java 后端开发框架组合，利用 Spring 提供的依赖注入、事务管理和 AOP 功能，Spring MVC 提供的 MVC 控制层功能，以及 MyBatis 提供的 ORM 功能。

第一章：搭建整合环境

创建mavenjavaWeb项目

1.整合说明：SSM整合可以使用多种方式，这里选择XML + 注解的方式

2.整合的思路

        1.先搭建整合的环境

        2.把Spring的配置搭建完成

        3.再使用Spring整合SpringMVC框架

        4.最后使用Spring整合MyBatis框架

3.创建数据库和表结构

mysql表

create database ssm;
​
create table account(
    id int primary key auto_increment,
    name varchar(20),
    money double
);

4.创建maven的工程

<?xml version="1.0" encoding="UTF-8"?>

</project>

部署ssm_web项目，只要把ssm_web项目加入到tomcat服务器中即可

5.编写实体类，在ssm_domain项目中编写

package com.qcby.domain;

import java.io.Serializable;

/**
 * 账户类
 */
public class Account implements Serializable{
    //主键
    private Integer id;
    //账户名称
    private String name;
    //账户的金额
    private Double money;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Double getMoney() {
        return money;
    }

    public void setMoney(Double money) {
        this.money = money;
    }

    @Override
    public String toString() {
        return "Account{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", money=" + money +
                '}';
    }
}

6.编写service接口和实现类

package com.qcby.service;

import com.qcby.domain.Account;

import java.util.List;

public interface AccountService {
    //查询所有
    public List<Account> findAll();
}
package com.qcby.service.impl;

import com.qcby.dao.AccountDao;
import com.qcby.domain.Account;
import com.qcby.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class AccountServiceImpl implements AccountService{
    @Autowired
    private AccountDao accountDao;

    @Override
    public List<Account> findAll() {
        System.out.println("业务层:查询所有的账号。。");
        return accountDao.findAll();
    }
}

第二章：Spring框架代码的编写

1.搭建和测试Spring的开发环境

创建applicationContext.xml的配置文件，编写具体的配置信息。

<?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">

    <!-- 开启注解扫描，要扫描的是service -->
    <context:component-scan base-package="com.qcby.service"/>
</beans>

2.编写测试方法，进行测试

package com.qcby.test;

import com.qcby.service.AccountService;

import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class TestSpring {

    @Test
    public void run1(){
        // 创建工厂，加载配置文件
        ApplicationContext ac = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
        // 获取service，对象，调用方法
        AccountService service = ac.getBean(AccountService.class);
        service.findAll();
    }
}

第三章：Spring整合SpringMVC框架

1.搭建和测试SpringMVC的开发环境

1.在web.xml中配置DispatcherServlet前端控制器

<?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_3_1.xsd"
         version="3.1"
         metadata-complete="true">
         
    <!--前端控制器-->
    <servlet>
        <servlet-name>dispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!-- 加载springmvc.xml配置文件 -->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:springmvc.xml</param-value>
        </init-param>
        <!-- 启动加载 -->
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcherServlet</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>
    
</web-app>

2.在web.xml中配置DispatcherServlet过滤器解决中文乱码

<!-- 解决post请求中文乱码的过滤器 -->
<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>

3.创建springmvc.xml的配置文件，编写配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"
       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
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">

    <!-- 扫描controller的注解，别的不扫描 -->
    <context:component-scan base-package="com.qcby.controller"></context:component-scan>
    <!-- 配置视图解析器 -->
    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- JSP文件所在的目录 -->
        <property name="prefix" value="/pages/" />
        <!-- 文件的后缀名 -->
        <property name="suffix" value=".jsp" />
    </bean>
    
    <!--设置静态资源不过滤
    <mvc:resources location="/css/" mapping="/css/**" />
    <mvc:resources location="/images/" mapping="/images/**" />
    <mvc:resources location="/js/" mapping="/js/**" />
    -->

    <!-- 开启对SpringMVC注解的支持-->
    <mvc:annotation-driven/>

</beans>

4.测试SpringMVC的框架搭建是否成功

编写index.jsp和list.jsp编写，超链接

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
    <h3>账号列表页面</h3>
    <a href="/account/findAll.do">查询所有</a>
</body>
</html>

创建AccountController类，编写方法，进行测试

package com.qcby.controller;

import com.qcby.domain.Account;
import com.qcby.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import java.util.List;

@Controller
@RequestMapping("/account")
public class AccountController {
    /**
     * 查询所有
     */
    @RequestMapping("/findAll.do")
    public ModelAndView findAll(){
        System.out.println("表现层:查询所有的账号...");
        //将数据传递给视图
        ModelAndView mv = new ModelAndView();
        mv.setViewName("suc");
        return mv;
    }
}

2. Spring整合SpringMVC的框架

1.目的：在controller中能成功的调用service对象中的方法。
2.在项目启动的时候，就去加载applicationContext.xml的配置文件，在web.xml中配置ContextLoaderListener监听器（该监听器只能加载WEB-INF目录下的applicationContext.xml的配置文件）。

<!-- 配置Spring的监听器 -->
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 配置加载类路径的配置文件 -->
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
</context-param>

3.在controller中注入service对象，调用service对象的方法进行测试

package com.qcby.controller;

import com.qcby.domain.Account;
import com.qcby.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import java.util.List;

@Controller
@RequestMapping("/account")
public class AccountController {

    //注入
    @Autowired
    private AccountService accountService;
    /**
     * 查询所有
     */
    @RequestMapping("/findAll.do")
    public ModelAndView findAll(){
        System.out.println("表现层:查询所有的账号...");

        //调用service对象的方法
        List<Account> list = accountService.findAll();
        //将数据传递给视图
        ModelAndView mv = new ModelAndView();
        mv.setViewName("suc");
        return mv;
    }
}

第四章：Spring整合MyBatis框架

1. 搭建和测试MyBatis的环境

编写AccountDao.xml映射配置文件

<?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.qcby.dao.AccountDao">

    <!-- 查询所有 -->
    <select id="findAll" resultType="com.qcby.domain.Account">
        select * from account
    </select>
</mapper>

在web项目中编写SqlMapConfig.xml的配置文件，编写核心配置文件

<?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>
    <!-- 配置环境 -->
    <environments default="mysql">
        <environment id="mysql">
            <transactionManager type="JDBC"/>
            <dataSource type="POOLED">
                <property name="driver" value="com.mysql.jdbc.Driver"/>
                <property name="url" value="jdbc:mysql://localhost:3306/ssm"/>
                <property name="username" value="root"/>
                <property name="password" value="2020"/>
            </dataSource>
        </environment>
    </environments>

    <!-- 加载映射配置文件 -->
    <mappers>
        <mapper resource="mappers/AccountDao.xml"/>
    </mappers>
</configuration>

在AccountDao接口的方法

package com.qcby.dao;

import com.qcby.domain.Account;
import org.apache.ibatis.annotations.Delete;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;
import org.apache.ibatis.annotations.Update;
import org.springframework.stereotype.Repository;
import org.springframework.web.bind.annotation.DeleteMapping;

import java.util.List;

public interface AccountDao {

    public List<Account> findAll();
}

编写测试的方法

package com.qcby.test;

import com.qcby.dao.AccountDao;
import com.qcby.domain.Account;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
import org.junit.Test;

import java.io.InputStream;
import java.util.List;

public class TestMyBatis {

    /**
     * 测试查询
     * @throws Exception
     */
    @Test
    public void run1() throws Exception{
        //加载配置文件
        InputStream inputStream = org.apache.ibatis.io.Resources.getResourceAsStream("SqlMapConfig.xml");
        //构建工厂
        SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(inputStream);
        //创建session
        SqlSession session = factory.openSession();
        //获取到代理对象
        AccountDao mapper = session.getMapper(AccountDao.class);
        //调用方法
        List<Account> list = mapper.findAll();
        for(Account account : list){
            System.out.println(account);
        }
        //关闭资源
        session.close();
        inputStream.close();
    }
}

2.Spring整合MyBatis框架

1.目的：把SqlMapConfig.xml配置文件中的内容配置到applicationContext.xml配置文件中

<?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">

    <!-- 开启注解扫描，要扫描的是service -->
    <context:component-scan base-package="com.qcby.service"/>

    <!-- 配置druid连接池 -->
    <!-- 配置开源连接池 Druid连接池 -->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <property name="url" value="jdbc:mysql:///ssm" />
        <property name="username" value="root" />
        <property name="password" value="2020" />
    </bean>

    <!-- Spring框架整合mybatis框架 -->
    <!-- 配置SqlSessionFactory工厂-->
    <bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 注入连接池对象 -->
        <property name="dataSource" ref="dataSource"/>
        <!-- 加载映射配置文件 -->
        <property name="mapperLocations" value="classpath:mappers/*.xml"/>
    </bean>

    <!-- 把dao对象存入到IOC容器中 -->
    <bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="sqlSessionFactory" ref="sessionFactory"/>
        <!-- 扫描dao所在的包，把包中接口的代码对象存入到IOC容器中 -->
        <property name="basePackage" value="com.qcby.dao"/>
    </bean>

    <!-- 配置Spring框架声明式事务管理-->
    <!-- 平台事务管理器 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>

    <!-- 配置事务的通知 -->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="find*" read-only="true"/>
            <tx:method name="*"/>
        </tx:attributes>
    </tx:advice>

    <!-- 配置AOP的增强-->
    <aop:config>
        <aop:advisor advice-ref="txAdvice" pointcut="execution(public * com.qcby.service.impl.*ServiceImpl.*(..))"/>
    </aop:config>
</beans>

2.在AccountDao接口中添加@Repository注解

3.在service中注入dao对象，进行测试

package com.qcby.service.impl;

import com.qcby.dao.AccountDao;
import com.qcby.domain.Account;
import com.qcby.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class AccountServiceImpl implements AccountService{
    @Autowired
    private AccountDao accountDao;

    @Override
    public List<Account> findAll() {
        System.out.println("业务层:查询所有的账号。。");
        return accountDao.findAll();
    }
}

controller代码如下

package com.qcby.controller;

import com.qcby.domain.Account;
import com.qcby.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import java.util.List;

@Controller
@RequestMapping("/account")
public class AccountController {

    //注入
    @Autowired
    private AccountService accountService;
    /**
     * 查询所有
     */
    @RequestMapping("/findAll.do")
    public ModelAndView findAll(){
        System.out.println("表现层:查询所有的账号...");

        //调用service对象的方法
        List<Account> list = accountService.findAll();
        for(Account account : list){
            System.out.println(account);
        }
        //将数据传递给视图
        ModelAndView mv = new ModelAndView();
        mv.setViewName("suc");
        return mv;
    }
