mybatis3学习：[4]CRUD之删除

编写UserInfoMapper.java /** * 删除用户信息 * @param userId */ public void deleteUser(Integer userId);

映射文件： userinfo.xml <!-- 删除 用户信息--> <delete id="deleteUser" parameterType="int" > delete from user_info where user_id=#{userId} </delete>

测试代码： @Test public void deleteUser() { try { // 获取映射 UserInfoMapper usermapper = ConnectionFactory     .getMapper(UserInfoMapper.class); usermapper.deleteUser(1013); //提交事务 ConnectionFactory.commit();  } catch (Exception e) { //回滚 ConnectionFactory.rollback(); e.printStackTrace(); } }
