用myBatis插入数据时，程序可以正常运行，但是数据却没有添加到数据库中

Posted 2023-02-25

package com.mybatis.demo;
import java.io.Reader;
public class Test
private static SqlSessionFactory sqlSessionFactory;
private static Reader reader;
static
try
reader = Resources.getResourceAsReader("Configuration.xml");
sqlSessionFactory = new SqlSessionFactoryBuilder().build(reader);
catch(Exception e)
e.printStackTrace();


public static SqlSessionFactory getSession()
return sqlSessionFactory;

//添加用户
public void addUser()
User user = new User();
user.setId(4);
user.setUserAddress("人民广场");
user.setUserName("Birds");
user.setUserAge("102");
SqlSession session = sqlSessionFactory.openSession();
try
IUserOperation userOperation = session.getMapper(IUserOperation.class);
session.commit();
System.out.println("当前增加的用户id为："+user.getId());

finally
session.close();


public static void main(String[] args)
Test testUser = new Test();
testUser.addUser();



<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"

<mapper namespace="com.mybatis.inter.IUserOperation" >
<select id="selectUserByID" parameterType="int" resultType="User" >
select * from user where id=#id
</select>
<insert id="addUser" parameterType="User"

insert into user(id,userName,userAge,userAddress) values(#id,#userName,#userAge,#userAddress)
</insert>
</mapper>

参考技术A getSqlMapClientTemplate().insert("Users.addUser",user);增加操作都没有本回答被提问者和网友采纳 参考技术B 记得执行 sqlSession.commit();
然后关闭sqlSession; 参考技术C 你哪执行保存了？
