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：

 1 @Test
 2     public void testAddUser() throws ParseException {
 3         SqlSession sqlSession = null;
 4         User user=new User();
 5         user.setUserCode("admin");
 6         user.setAddress("中国河北省张家口市");
 7         user.setGender(1);
 8         user.setUserName("小黑");
 9         user.setBirthday(new SimpleDateFormat("yyyy-MM-dd").parse("2019-10-24"));//注意要转化成date类型的数据
10         user.setUserPassword("111111");
11         int count=0;//返回受影响的行数
12         try {
13             sqlSession = MyBatisUtil.createSqlSession();
14             //使用mapper映射的方式实现
15             //userList2 = sqlSession.selectList("cn.smbms.dao.user.UserMapper.getUserListByUserName",userNameString);
16             //调用mapper接口的方式实现
17              count= sqlSession.getMapper(UserMapper.class).addUser(user);
18             // 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
19              mlogger.info("返回受影响的行数：" + count);
20             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
21         } catch (Exception e) {
22             // TODO: handle exception
23         } finally {
24             // 最后一定要注意：关闭会话
25             MyBatisUtil.closeSqlSession(sqlSession);
26 
27         }
28         
29 
30     }

运行结果：
