所有需要的JAR包都引入以后，首先进行Spring与MyBatis的整合，然后再进行JUnit测试，先看一个项目结构图：
1.2.1、建立JDBC属性文件
jdbc.properties（文件编码修改为utf-8）
driver=com.mysql.jdbc.Driver
url=jdbc:mysql://127.0.0.1:3306/ssm
username=root
password=root
#定义初始连接数
initialSize=0
#定义最大连接数
maxActive=20
#定义最大空闲
maxIdle=20
#定义最小空闲
minIdle=1
#定义最长等待时间
maxWait=60000 1.2.2、建立spring-mybatis.xml配置文件
这个文件就是用来完成spring和mybatis的整合的。这里面也没多少行配置，主要的就是自动扫描，自动注入，配置数据库。注释也很详细，大家看看就明白了。
spring-mybatis.xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

beans>1.2.3、Log4j的配置
log4j.properties
#定义LOG输出级别
log4j.rootLogger=INFO,Console,File
#定义日志输出目的地为控制台
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
#可以灵活地指定日志输出格式，下面一行是指定具体的格式
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n
#文件大小到达指定尺寸的时候产生一个新的文件
log4j.appender.File = org.apache.log4j.RollingFileAppender
#指定输出目录
log4j.appender.File.File = logs/ssm.log
#定义文件最大大小
log4j.appender.File.MaxFileSize = 10MB
# 输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n 1.2.4、JUnit测试
经过以上步骤（到4.2.2，log4j不配也没影响），已经完成了Spring和mybatis的整合，这样我们就可以编写一段测试代码来试试是否成功了。
4.2.4.1、创建测试用表
既然需要测试，那么就需要建立在数据库中建立一个测试表，_t是为了体现mybatis的自动驼峰命名。SQL语句为：
DROP TABLE IF EXISTS `user_t`;
CREATE TABLE `user_t` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`user_name` varchar(40) NOT NULL,
`password` varchar(255) NOT NULL,
`age` int(4) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;
/*Data for the table `user_t` */
insert into `user_t`(`id`,`user_name`,`password`,`age`) values (1,'测试','sfasgfaf',24); 1.2.4.2、利用MyBatis Generator自动创建代码
这个可根据表自动创建实体类、MyBatis映射文件以及DAO接口，当然，我习惯将生成的接口名改为IUserDao，而不是直接用它生成的UserMapper。如果不想麻烦就可以不改。完成后将文件复制到工程中。如图：
1.2.4.3、建立Service接口和实现类
IUserService.jave
package com.yjq.ssm.service;
import com.yjq.ssm.model.UserT;
public interface UserTService {
public UserT getUserById(int userId);
}
UserServiceImpl.java
package com.yjq.ssm.service.impl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.yjq.ssm.dao.UserTMapper;
import com.yjq.ssm.model.UserT;
import com.yjq.ssm.service.UserTService;
@Service
public class UserTServiceImpl implements UserTService {
@Autowired
private UserTMapper userTDao;
public UserT getUserById(int userId) {
return this.userTDao.selectByPrimaryKey(userId);
}
}
1.2.4.4、建立测试类
package com.yjq.ssm.test;
import org.apache.log4j.Logger;
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 com.alibaba.fastjson.JSON;
import com.yjq.ssm.model.UserT;
import com.yjq.ssm.service.UserTService;
@RunWith(SpringJUnit4ClassRunner.class) //表示继承了SpringJUnit4ClassRunner类
@ContextConfiguration(locations = {"classpath:spring.xml"})
public class TestMyBatis {
private static Logger logger = Logger.getLogger(TestMyBatis.class);
// private ApplicationContext ac = null; 未引入spring，则需要getbean方式测试
@Autowired
private UserTService userTService = null;
// @Before
// public void before() {
// ac = new ClassPathXmlApplicationContext("applicationContext.xml");
// userService = (IUserService) ac.getBean("userService");
// }
@Test
public void test1() {
UserT user = userTService.getUserById(1);
// System.out.println(user.getUserName());
// logger.info("值："+user.getUserName());
logger.info(JSON.toJSONString(user));
}
}至此，完成Spring和mybatis这两大框架的整合，下面在继续进行SpringMVC的整合。
1.3、整合SpringMVC
1.3.1、配置spring-mvc.xml

web.xml
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"

1.3.3.1、新建jsp页面
showUser.jsp
此页面仅输出一下用户名，完成一个完整的简单流程。
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<html>
<head>
<title>测试title>
head>
<body>
${user.userName}

html> 1.3.3.2、建立UserController类
UserController.java 控制器
package com.yjq.ssm.controller;
import javax.servlet.http.HttpServletRequest;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import com.yjq.ssm.model.UserT;
import com.yjq.ssm.service.UserTService;
@Controller
@RequestMapping("/user")
public class UserTController {
@Autowired
private UserTService userTService;
@RequestMapping("/showUser")
public String toIndex(HttpServletRequest request,Model model){
int userId = Integer.parseInt(request.getParameter("id"));
UserT user = this.userTService.getUserById(userId);
model.addAttribute("user", user);
return "showUser";
}
}
1.3.3.3、部署项目
输入地址：localhost:8080/项目名称/user/showUser?id=1
