项目要整合springMVC和mybatis，看了一下网上的例子，没有几个能真正跑通的，为了方便后续的开发的使用，也为了方便一些新人的学习，少走一些弯路，特把今天做的一个整合记录一下，如果有什么地方有待改进，还希望各位能提出有价值的宝贵意见。

首先准备一下所需要的依赖

mybatis

mybatis-3.1.1.jar

mybatis-spring-1.1.1.jar(mybatis提供的用于整合spring的jar包，下载的时候一定要下载1.1版本，不然程序会报异常的)

spring

                  org.springframework.aop-3.1.2.RELEASE.jar
                  org.springframework.asm-3.1.2.RELEASE.jar
                  org.springframework.beans-3.1.2.RELEASE.jar
                  org.springframework.context-3.1.2.RELEASE.jar
                  org.springframework.core-3.1.2.RELEASE.jar
                  org.springframework.expression-3.1.2.RELEASE.jar
                  org.springframework.jdbc-3.1.2.RELEASE.jar
                  org.springframework.transaction-3.1.2.RELEASE.jar
                  org.springframework.web-3.1.2.RELEASE.jar
                  org.springframework.web.servlet-3.1.2.RELEASE.jar

其他依赖

aopalliance-1.0.jar(这个需要自己从网上下载)
mysql-connector-java-5.1.21-bin.jar

commons-dbcp-1.2.2.jar

               commons-pool-1.3.jar
                 commons-logging.jar
                  jstl.jar

下面开始粘贴代码了

domain实体

public class User {

private Integer id;
private String userName;
private String password;

public Integer getId() {
return id;
}

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

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;
}
}

DAO层（接口代码省略了）

@Repository("userDao")
@Transactional
public class UserDaoImpl implements UserDao {
@Resource
private SqlSessionTemplate sqlSessionTemplate;
public void saveUser(User user) {
sqlSessionTemplate.insert("com.cn.dao.UserDao.saveUser", user);
}

}

mybatis_config.xml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>
<typeAliases>
<typeAlias alias="Users" type="com.cn.domain.User"/>
</typeAliases>
</configuration>

UserMapper.xml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.cn.dao.UserDao">
<insert id="saveUser" parameterType="Users">
insert into users(userName,password) values(#{userName},#{password})
</insert>
</mapper>

spring.xml配置文件

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

</bean>


<bean id="tx" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>
<tx:annotation-driven transaction-manager="tx"/>
</beans>

测试代码

@Test
public void testSaveUser() {
  ApplicationContext applicationContext = new ClassPathXmlApplicationContext(
    "spring.xml");
  UserDao userDao = (UserDao) applicationContext.getBean("userDao");
  User user=new User();
          user.setUserName("lisisisi");
          user.setPassword("1111");
  userDao.saveUser(user);
}

完工！
