MyBatis中sqlSession操作数据库,不报错但无法实现数据修改(增、改、删)
public void addCustomerTest() throws Exception {
SqlSession sqlSession = MyBatisUtils.getSession();
CustomerMapper customerMapper = sqlSession.getMapper(CustomerMapper.class);
Customer customer = new Customer();
customer.setUsername("111");
customer.setJobs("111");
customer.setPhone("111");
customerMapper.addCustomer(customer);
sqlSession.commit();
sqlSession.close();
}
数据库查询操作可实现,但修改无法实现,且不报错,出现这种情况的原因之一:
事务忘记提交!
添加代码sqlSession.commit();
长点心就能少犯错误。
看似简单的知识背后,承载的是收获和成长!
