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：
