MyBatis框架的insert节点-向数据库中插入数据

需求：使用mybatis框架中的insert元素节点向数据库中插入数据

UserMapper.xml

 

 UserMapper.java

 

 编写测试方法：

@Test
    public void testAddUser() throws ParseException {
        SqlSession sqlSession = null;
        User user=new User();
        user.setUserCode("admin");
        user.setAddress("中国河北省张家口市");
        user.setGender(1);
        user.setUserName("小黑");
        user.setBirthday(new SimpleDateFormat("yyyy-MM-dd").parse("2019-10-24"));//注意要转化成date类型的数据
        user.setUserPassword("111111");
        int count=0;//返回受影响的行数
        try {
            sqlSession = MyBatisUtil.createSqlSession();
            //使用mapper映射的方式实现
            //userList2 = sqlSession.selectList("cn.smbms.dao.user.UserMapper.getUserListByUserName",userNameString);
            //调用mapper接口的方式实现
             count= sqlSession.getMapper(UserMapper.class).addUser(user);
            // int i=1/0;//模拟异常  后台日志打印出rolling back表示没有插入成功，事务进行了回滚
             mlogger.info("返回受影响的行数：" + count);
            sqlSession.commit();//后台日志打印出rolling back表示没有提交事务，事务进行了回滚，所以必须得提交事务才行
        } catch (Exception e) {
            // TODO: handle exception
        } finally {
            // 最后一定要注意：关闭会话
            MyBatisUtil.closeSqlSession(sqlSession);

        }
        

    }

运行结果：
