1. 搭建整合环境

采用 XML+ 注解的方式进行整合
整合思路：
- 先搭建整合环境
- 再把 Spring 配置搭建完成
- 再使用 Spring 整合 SpringMVC 框架
- 最后使用 Spring 整合 MyBatis 框架

创建数据库和表结构

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

Maven 坐标

</project>

编写实体类，在 domain 包中

package pers.ylq.domain;

import java.io.Serializable;

public class Account implements Serializable {
    private Integer id;
    private String name;
    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 +
                '}';
    }
}

编写 dao 层接口

package pers.ylq.dao;

import pers.ylq.domain.Account;

import java.util.List;

public interface AccountDao {
    public void saveAccount(Account account);

    public List<Account> findAll();
}

编写 service 接口

package pers.ylq.service;

import pers.ylq.domain.Account;

import java.util.List;

public interface AccountService {
    void saveAccount(Account account);

    List<Account> findAll();
}

编写 service 实现类

package pers.ylq.service.impl;

import org.springframework.stereotype.Service;
import pers.ylq.dao.AccountDao;
import pers.ylq.domain.Account;
import pers.ylq.service.AccountService;

import java.util.List;

@Service("accountService")
public class AccountServiceImpl implements AccountService {

    private AccountDao accountDao;

    @Override
    public void saveAccount(Account account) {
        System.out.println("业务层：保存账号...");
    }

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

2. Spring 框架代码的编写

搭建 Spring 开发环境

<?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和dao层的注解，要忽略web层注解，web层让SpringMVC框架去管理 -->
    <context:component-scan base-package="pers.ylq">
        <!-- 配置要忽略的注解 -->
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>
</beans>

Spring 和 SpringMVC 配置文件都会去扫描包。
Spring 通过容器对象 ClassPathXmlApplicationContext 加载配置文件，SpringMVC 在 web.xml 中配置前端控制器的时候加载 springmvc.xml 配置文件。
那么会有两个容器，Spring 的是父容器，springmvc 的是子容器。
我们需要让 SpringMVC 只扫描 Controller，让 Spring 扫描全部包，但排除 Controller

编写测试类进行测试

package pers.ylq.test;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import pers.ylq.service.AccountService;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:applicationContext.xml")
public class TestSpring {
    @Autowired
    private AccountService accountService;

    @Test
    public void run1(){
        accountService.findAll();
    }
}

3. SpringMVC 环境搭建

在 web.xml 中配置 DispatcherServlet 前端控制器和中文乱码过滤器

<!DOCTYPE web-app PUBLIC
        "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
        "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
    <display-name>Archetype Created Web Application</display-name>

    <!-- 配置解决中文乱码的过滤器 -->
    <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>

    <!-- 配置前端控制器：服务器启动必须加载，需要加载springmvc.xml配置文件 -->
    <servlet>
        <servlet-name>dispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!-- 配置初始化参数，创建完DispatcherServlet对象，加载springmvc.xml配置文件 -->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:springmvc.xml</param-value>
        </init-param>
        <!-- 服务器启动的时候，让DispatcherServlet对象创建 -->
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

创建 springmvc.xm l 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="pers.ylq">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <!-- 配置视图解析器 -->
    <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- JSP文件所在的目录 -->
        <property name="prefix" value="/WEB-INF/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>

测试 SpringMVC 的框架搭建是否成功

编写 index.jsp 和 list.jsp 编写，超链接

<a href="account/findAll">查询所有</a>

创建 AccountController 类，编写方法，进行访问测试

package pers.ylq.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@RequestMapping("/account")
public class AccountController {
    @RequestMapping("/findAll")
    public String findAll(){
        System.out.println("表现层：查询所有账户...");
        return "list";
    }
}

4. Spring 整合 SpringMVC 框架

目的：在 controller 中能成功的调用 service 对象中的方法。
原理：
- 配置一个监听器，监听 ServletContext 域对象的创建，在监听器中加载配置文件，创建工厂，存储到 ServletContext 域中。
- Spring 已经帮我们创建好了这个监听器(ContextLoaderListener)，我们加载即可。

在 web.xml 中配置 ContextLoaderListener 监听器

<!-- 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>

该监听器只能加载 WEB-INF 目录下的 applicationContext.xml 的配置文件，配置文件放置在 resources 目录下，我们需要手动配置加载路径。

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

package pers.ylq.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import pers.ylq.service.AccountService;

@Controller
@RequestMapping("/account")
public class AccountController {
    @Autowired
    private AccountService accountService;

    @RequestMapping("/findAll")
    public String findAll() {
        System.out.println("表现层：查询所有账户...");
        accountService.findAll();
        return "list";
    }
}

测试跳转。

5. MyBatis 环境搭建

编写数据库配置文件 jdbcConfig.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssm
jdbc.username=root
jdbc.password=123456

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>

    <!-- 引入类路径下的数据库配置文件   -->
    <properties resource="jdbcConfig.properties"/>

    <!-- 给domain中的包起别名   -->
    <typeAliases>
        <package name="pers.ylq.domain"/>
    </typeAliases>
    <!--  配置数据库     -->
    <environments default="mysql">
        <environment id="mysql">
            <transactionManager type="JDBC"></transactionManager>
            <dataSource type="POOLED">
                <property name="driver" value="${jdbc.driver}"/>
                <property name="url" value="${jdbc.url}"/>
                <property name="username" value="${jdbc.username}"/>
                <property name="password" value="${jdbc.password}"/>
            </dataSource>
        </environment>
    </environments>

    <!-- 映射文件   -->
    <mappers>
        <package name="pers.ylq.dao"/>
    </mappers>
</configuration>

在 AccountDao 接口的方法上添加注解，编写 SQL 语句

package pers.ylq.dao;

import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;
import pers.ylq.domain.Account;

import java.util.List;

public interface AccountDao {
    @Insert("insert into account(name,money) values(#{name},#{money})")
    public void saveAccount(Account account);

    @Select("select * from account")
    public List<Account> findAll();
}

编写测试方法

package pers.ylq.test;


import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
import org.junit.Test;
import pers.ylq.dao.AccountDao;
import pers.ylq.domain.Account;

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

public class TestMyBatis {
    @Test
    public void run1() throws IOException {
        // 加载配置文件
        InputStream inputStream = Resources.getResourceAsStream("SqlMapConfig.xml");
        // 创建工厂
        SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(inputStream);
        // 创建sqlSession对象，并设置自动提交
        SqlSession sqlSession = factory.openSession(true);
        // 获取代理对象
        AccountDao dao = sqlSession.getMapper(AccountDao.class);
        // 调用查询的方法
        List<Account> list = dao.findAll();
        for (Account account : list) {
            System.out.println(account);
        }
        // 释放资源
        sqlSession.close();
        inputStream.close();
    }

    @Test
    public void run2() throws Exception {
        Account account = new Account();
        account.setName("熊大");
        account.setMoney(400d);
        InputStream inputStream = Resources.getResourceAsStream("SqlMapConfig.xml");
        SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(inputStream);
        SqlSession sqlSession = factory.openSession();
        AccountDao dao = sqlSession.getMapper(AccountDao.class);
        dao.saveAccount(account);
        sqlSession.commit();
        sqlSession.close();
        inputStream.close();
    }
}

6. Spring 整合 MyBatis 框架

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


<!-- Spring整合MyBatis   -->
<!-- 读取数据库配置文件 -->
<context:property-placeholder location="classpath:jdbcConfig.properties"/>
<!-- 配置C3P0的连接池对象 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.DriverManagerDataSource">
    <property name="driverClass" value="${jdbc.driver}"/>
    <property name="jdbcUrl" value="${jdbc.url}"/>
    <property name="user" value="${jdbc.username}"/>
    <property name="password" value="${jdbc.password}"/>
</bean>

<!-- 配置SqlSession的工厂 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <!-- 配置 下划线转驼峰式 -->
    <property name="configuration">
        <bean class="org.apache.ibatis.session.Configuration">
            <property name="mapUnderscoreToCamelCase" value="true"/>
        </bean>
    </property>
</bean>

<!-- 配置扫描dao的包 -->
<bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="pers.ylq.dao"/>
</bean>

在 AccountDao 接口中添加 @Repository 注解

在 service 中注入 dao 对象，进行测试

package pers.ylq.service.impl;

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

import java.util.List;

@Service("accountService")
public class AccountServiceImpl implements AccountService {

    @Autowired
    private AccountDao accountDao;

    @Override
    public void saveAccount(Account account) {
        System.out.println("业务层：保存账号...");
    }

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

7. 配置 Spring 的声明式事务管理

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

<!-- 配置事务通知   -->
