一、搭建SSM的整合环境

1.1、SSM整合的思路

1.先搭建整合的环境

2.Spring的配置搭建

3.Spring整合SpringMVC

4.Spring整合Mybatis

1.2、创建数据库和表

CREATE TABLE `ssm_user` (
	`id` INT ( 11 ) NOT NULL AUTO_INCREMENT,
	`username` VARCHAR ( 20 ) DEFAULT NULL,
	`password` VARCHAR ( 20 ) DEFAULT NULL,
PRIMARY KEY ( `id` ) 
) ENGINE = INNODB DEFAULT CHARSET = utf8

1.3、创建Maven工程

1.3.1、创建SSM的Maven工程

SSM框架的整合

1.3.2、导入需要的依赖

1.4、编写一个JavaBean的类

package cn.waggag.domain;

import java.io.Serializable;

/**
 * @description: 用户的实体类
 * @author waggag
 * @Data 2019年7月19日下午6:04:44
 * @Company www.waggag.cn
 */
public class User implements Serializable{
	
	private String username;
	private String password;
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	@Override
	public String toString() {
		return "User [username=" + username + ", password=" + password + "]";
	}
	
}

1.5、创建基本的包结构和类

SSM框架的整合

1.6、Dap层

package cn.waggag.mapper;

import java.util.List;

import cn.waggag.domain.User;

/**
 * @description: 用户的mapper接口
 * @author waggag
 * @Data 2019年7月19日下午6:10:45
 * @Company www.waggag.cn
 */
public interface UserMapper {
	
	//查询所有用户
	public List<User> findAll();
	
	//添加一个用户
	public void addUser(User user);
	
}

1.7、Service层

//接口
public interface UserService {

	// 查询所有用户
	public List<User> findAll();

	// 添加一个用户
	public void addUser(User user);

}

//实现类

package cn.waggag.service.impl;
import java.util.List;
import cn.waggag.domain.User;
import cn.waggag.service.UserService;
public class UserServiceImpl implements UserService {

	@Override
	public List<User> findAll() {
		System.out.println("Service的findAll");
		return null;
	}

	@Override
	public void addUser(User user) {
		System.out.println("Service的addUser");
	}

}

1.8、Controller层

package cn.waggag.controller;

public class UserController {

}

二、Spring环境的搭建

2.1、在resources下创建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"
       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 -->
        <context:component-scan base-package="cn.waggag.*">
        	<!-- 排除Controller的注解扫描 -->
        	<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
        </context:component-scan>
        
</beans>

2.2、UserService加上注解扫描

package cn.waggag.service.impl;
import java.util.List;
import org.springframework.stereotype.Service;
import cn.waggag.domain.User;
import cn.waggag.service.UserService;
@Service("accountService")
public class UserServiceImpl implements UserService {
	@Override
	public List<User> findAll() {
		System.out.println("Service的findAll");
		return null;
	}
	@Override
	public void addUser(User user) {
		System.out.println("Service的addUser");
	}
}

2.3、测试Spring的搭建

package cn.waggag.test;

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

import cn.waggag.service.UserService;

/**
 * 测试Spring环境的搭建
 * @description:
 * @author waggag
 * @Data 2019年7月19日下午6:32:40
 * @Company www.waggag.cn
 */
public class testSpring {
	
	@Test
	public void testSpring() {
		//加载配置文件
		ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
		//获取对象
		UserService userService = applicationContext.getBean("accountService",UserService.class);
		//调用service方法
		userService.findAll();
		
	}

}

三、SpringMVC环境的搭建

3.1、web.xml配置前端控制器

     <!-- post乱码过滤器 -->
    <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SpringMVC-->
    <!--前端控制器-->
    <servlet>
        <servlet-name>dispatcherServlet</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>
        <!-- 配置servlet启动时加载对象 -->
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

3.2、创建springmvc.xml的配置文件

<?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">

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

	<!--配置包扫描器，扫描@Controller注解的类 -->
	<context:component-scan
		base-package="cn.waggag.controller">
		<context:include-filter type="annotation"
			expression="org.springframework.stereotype.Controller" />
	</context:component-scan>

	<!--配置的视图解析器对象 -->
	<bean id="internalResourceViewResolver"
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="/WEB-INF/pages/" />
		<property name="suffix" value=".jsp" />
	</bean>

	<!--过滤静态资源,谷歌可以正常浏览，火狐等必须配置资源映射才能访问静态资源文件 -->
	<mvc:resources location="/css/" mapping="/css/**" />
	<mvc:resources location="/images/" mapping="/images/**" />
	<mvc:resources location="/js/" mapping="/js/**" />

</beans>

3.3、UserController加上注解

package cn.waggag.controller;

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

@Controller
@RequestMapping("/user")
public class UserController {

   @RequestMapping("/findAll")
   public String testSpringMVC() {
       System.out.println("Controller的findAll");
       return "list";
   }
}
3.4、测试SpringMVC的搭建

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>TestSpringMVC</title>
</head>
<body>
    <a href="user/findAll">测试SpringMVC</a>
</body>
</html>

四、Spring整合SpringMVC

4.1、web.xml中在项目创建的时候加载Spring的配置文件

     <!--设置Spring的配置文件的路径-->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
     <!--初始化spring容器,项目启动的时候加载Spring的配置文件-->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

4.2、Controller中注入UserService

package cn.waggag.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import cn.waggag.service.UserService;
@Controller
@RequestMapping("/user")
public class UserController {
	
	@Autowired
	private UserService userService;
	
	@RequestMapping("/findAll")
	public String testSpringMVC() {
		System.out.println("Controller的findAll");
		userService.findAll();
		return "list";
	}
}

五、Mybatis的环境搭建

5.1、UserDao使用注解，不提供映射文件

package cn.waggag.mapper;

import java.util.List;

import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;

import cn.waggag.domain.User;

/**
 * @description: 用户的mapper接口
 * @author waggag
 * @Data 2019年7月19日下午6:10:45
 * @Company www.waggag.cn
 */
@Repository
public interface UserMapper {
	
	//查询所有用户
	@Select("select * from ssm_user;")
	public List<User> findAll();
	
	//添加一个用户
	@Insert("insert into ssm_user(username,password) values(#{username},#{password})")
	public void addUser(User user);
	
}

5.2、创建配置文件SqlMapConfig.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>
    <!-- 配置连接数据库的信息 -->
    <properties resource="jdbc.properties"></properties>
    <!-- 配置mybatis的环境 -->
    <environments default="mysql">
        <environment id="mysql">
            <!-- 配置事务管理 -->
            <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>

    <!-- 指定映射文件位置 -->
    <mappers>
        <package name="cn.waggag.mapper"/>
    </mappers>
</configuration>

5.3、手动加载配置文件，测试Mybatis的环境。

package cn.waggag.test;

import java.io.InputStream;

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 cn.waggag.mapper.UserMapper;

public class testMybatis {
	
	@Test
	public void testMybatis() throws Exception {
		//1.加载配置文件
		InputStream inputStream = Resources.getResourceAsStream("SqlMapConfig.xml");
		//2.获取SqlSessionFactory
		SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream);
		//3.获取SqlSession
		SqlSession sqlSession = sqlSessionFactory.openSession();
		//4.获取Dao对象
		UserMapper userMapper = sqlSession.getMapper(UserMapper.class);
		//5.调用方法
        //更新删除的方法测试需要手动提交事务sqlSession.commit()
		userMapper.findAll();
		//6.释放资源
		inputStream.close();
		sqlSession.close();
	}
	
}

六、Spring整合Mybatis

6.1、applicationContext.xml整合Mybatis

        <!--spring整合Mybatis框架-->
	    <!--加载数据库配置文件-->
	    <context:property-placeholder location="classpath:jdbc.properties"/>
	    <!--配置连接池-->
	    <bean id="c3p0DataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
	        <property name="driverClass" value="${jdbc.driver}"></property>
	        <property name="jdbcUrl" value="${jdbc.url}"></property>
	        <property name="user" value="${jdbc.username}"></property>
	        <property name="password" value="${jdbc.password}"></property>
	    </bean>
	    <bean id="druidDataSource" class="com.alibaba.druid.pool.DruidDataSource" destroy-method="close">
	        <property name="driverClassName" value="${jdbc.driver}"></property>
	        <property name="url" value="${jdbc.url}"></property>
	        <property name="username" value="${jdbc.username}"></property>
	        <property name="password" value="${jdbc.password}"></property>
	    </bean>
	    <!--配置SqlSessionFactory工厂-->
	    <!--让spring管理SqlSessionFactory 使用Mybatis和Spring整合包中的SqlSessionFactoryBean-->
	    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
	        <!-- 数据库连接池 -->
	        <property name="dataSource" ref="druidDataSource"></property>
	        <!--加载Mybatis的全局配置文件,保留Mybatis的配置文件 -->
	        <property name="configLocation" value="classpath:SqlMapConfig.xml" />
	    </bean>
	    <!--配置映射文件所在位置-->
	    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
	        <property name="basePackage" value="cn.waggag.*"></property>
	    </bean>

6.2、UserService中使用注解自动注入UserMapper。

@Autowired
private UserMapper userMapper;

6.3、配置Spring的声明式事务管理，在applicationContext.xml中配置声明式事务。

  <!--配置Spring框架的声明式事务管理-->
    <!--配置事务管理器-->
    <bean id="dataSourceTransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="druidDataSource"></property>
    </bean>
    <!--配置事务通知-->
    <tx:advice id="txAdvice" transaction-manager="dataSourceTransactionManager">
        <tx:attributes>
            <!-- 传播行为,方法用这些开头，开启事务 -->
            <tx:method name="save*" propagation="REQUIRED" />
            <tx:method name="insert*" propagation="REQUIRED" />
            <tx:method name="add*" propagation="REQUIRED" />
            <tx:method name="create*" propagation="REQUIRED" />
            <tx:method name="delete*" propagation="REQUIRED" />
            <tx:method name="update*" propagation="REQUIRED" />
            <tx:method name="find*" propagation="SUPPORTS" read-only="true" />
            <tx:method name="select*" propagation="SUPPORTS" read-only="true" />
            <tx:method name="get*" propagation="SUPPORTS" read-only="true" />
        </tx:attributes>
    </tx:advice>
    <!--配置AOP增强-->
    <aop:config>
        <aop:advisor advice-ref="txAdvice"
                     pointcut="execution(* cn.waggag.service.*.*(..))"></aop:advisor>
    </aop:config>

七、总结。

一步一步的配置测试，SSM框架的搭建也不算太过于麻烦，关键配置文件的配置，使用IDEA的可以添加模板，将常用的配置加入模板，以后使用很方便。个人推荐使用IDEA，用Myeclipse搭建Maven项目的，期间碰到了各种的问题，反正我以后是尽量不用Myeclipse了。
