   mybatis config xml配置：

  mybatis-config.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">

        <setting name="localCacheScope" value="STATEMENT"/>

        
    </settings>
</configuration>

 

 

 

  Mapper sql配置：

    TestUserMapper.xml：

   

<?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.app.test.dbt.mapper.TestUserMapper">

         INSERT INTO test_user (id, name) VALUES(#{id}, #{name})
    </insert>
    <delete id="deleteUser" parameterType="int">
        delete from test_user where id= #{id}
    </delete>
    <update id="updateName" timeout="20">
        update test_user set name=#{param1} where  id= #{param2}
    </update>
</mapper>

    

 

Mapper  接口：

  TestUserMapper.java

 

/**
*  方法名与上面的（TestUserMapper.xml） id一至
*  上面的Namespace == java包名+类名
*/
public interface TestUserMapper {
    public void insertUser(TestUserModel user);
    public void deleteUser(int userId);
    public int updateName(String name,int userId);
}

 

 

 service类：

  

  

public class TestUserService {
	 TestUserMapper testUserMapper;

    public TestUserMapper getTestUserMapper() {
        return testUserMapper;
    }

    public void setTestUserMapper(TestUserMapper testUserMapper) {
        this.testUserMapper = testUserMapper;
    }
	public void insertUser(){
        int initValue=1;
        int times = 10;
        for(int i=0;i<times;i++){
            TestUserModel testUserModel  = new TestUserModel();
            byte id = (byte)(initValue+i);
            testUserModel.setId(id);
            testUserModel.setName("me");
            this.testUserMapper.insertUser(testUserModel);
        }

    }
}

 

 

测试类：

  

 public static void main(String args []){
        ClassPathXmlApplicationContext classPathXmlApplicationContextTransaction = 
            new ClassPathXmlApplicationContext("classpath*:/test.xml");
        TestUserService testUserService = (TestUserService) 
         classPathXmlApplicationContextTransaction.getBean("TestUserService");
        testUserService.insertUser();
    }
