<version>1.9</version>
</dependency>
</dependencies> 1.2、Spring与MyBatis的整合
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
<?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:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.1.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">
<!-- 自动扫描 -->
<context:component-scan base-package="com.yjq.ssm" />
<!-- 引入配置文件 -->
<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="classpath:jdbc.properties" />
</bean>
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="$driver" />
<property name="url" value="$url" />
<property name="username" value="$username" />
<property name="password" value="$password" />
<!-- 初始化连接大小 -->
<property name="initialSize" value="$initialSize"></property>
<!-- 连接池最大数量 -->
<property name="maxActive" value="$maxActive"></property>
<!-- 连接池最大空闲 -->
<property name="maxIdle" value="$maxIdle"></property>
<!-- 连接池最小空闲 -->
<property name="minIdle" value="$minIdle"></property>
<!-- 获取连接最大等待时间 -->
<property name="maxWait" value="$maxWait"></property>
</bean>
<!-- spring和MyBatis完美整合，不需要mybatis的配置映射文件 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<!-- 自动扫描mapping.xml文件 -->
<property name="mapperLocations" value="classpath:com/yjq/ssm/mapper/*.xml"></property>
</bean>
<!-- DAO接口所在包名，Spring会自动查找其下的类 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.yjq.ssm.dao" />
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
</bean>
<!-- (事务管理)transaction manager, use JtaTransactionManager for global tx -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
</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] [%dyyyy-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
<?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:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.1.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">
<!-- 自动扫描该包，使SpringMVC认为包下用了@controller注解的类是控制器 -->
<context:component-scan base-package="com.yjq.ssm.controller" />
<!--避免IE执行AJAX时，返回JSON出现下载文件 -->
<bean id="mappingJacksonHttpMessageConverter"
class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>text/html;charset=UTF-8</value>
</list>
</property>
</bean>
<!-- 启动SpringMVC的注解功能，完成请求和注解POJO的映射 -->
<bean
class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="messageConverters">
<list>
<ref bean="mappingJacksonHttpMessageConverter" /> <!-- JSON转换器 -->
</list>
</property>
</bean>
<!-- 定义跳转的文件的前后缀 ，视图模式配置-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 这里的配置我的理解是自动给后面action的方法return的字符串加上前缀和后缀，变成一个 可用的url地址 -->
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
<!-- 配置文件上传，如果没有使用文件上传可以不用配置，当然如果不配，那么配置文件中也不必引入上传组件包 -->
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<!-- 默认编码 -->
<property name="defaultEncoding" value="utf-8" />
<!-- 文件大小最大值 -->
<property name="maxUploadSize" value="10485760000" />
<!-- 内存中的最大值 -->
<property name="maxInMemorySize" value="40960" />
</bean>
</beans> 1.3.2、配置web.xml文件
web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
version="3.0">
<display-name>Archetype Created Web Application</display-name>
<!-- Spring和mybatis的配置文件 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-mybatis.xml</param-value>
</context-param>
<!-- 编码过滤器 -->
<filter>
<filter-name>encodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<async-supported>true</async-supported>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- Spring监听器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 防止Spring内存溢出监听器 -->
<listener>
<listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
</listener>
<!-- Spring MVC servlet -->
<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:spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
<async-supported>true</async-supported>
</servlet>
<servlet-mapping>
<servlet-name>SpringMVC</servlet-name>
<!-- 此处可以可以配置成*.do，对应struts的后缀习惯 -->
<url-pattern>/</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>/index.jsp</welcome-file>
</welcome-file-list>
</web-app> 1.3.3、测试
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"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>测试</title>
</head>
<body>
$user.userName
</body>
</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
