在Mybatis中 mapper中
boolean updateRegisterCompanyFlag(@Param(value = "companyId") String companyId,
@Param(value = "flag") String flag);
传入的flag类型为String，但在mapper.XML中进行判断是下意识地以为判断的值要加上引号
, LAST_CHECK_TIME = sysdate
但是这样写，传入flag=“4”后，这个if语句一直不成立s
ql没有拼接。后来网上查了一番后将 test 中的 4 的引号去除才成功。
, LAST_CHECK_TIME = sysdate
记录一下，以防忘记。。。
补充知识：Mybatis中xml的有关if test以及==的用法
Mybatis中，通常都要在mapper.xml中写复杂的sql语句，结合页面的查询筛选条件，需要在sql语句中加入
与页面都要一一对应，除此之外，还需要在实体类中有定义。
另外，mybatis中
注意 仅仅需要将双引号和单引号的位置换一下即可!!!
