回复了 cway 创建的主题 程序员 MyBatis 有问<if test="param!=null">问题
@mosesyou 如果空格不是 null 应该会进去以上这个条件呀!

然后我又发现如果 if test="param!=null||param!=‘’ " 。

这个条件反而能进来,这样就奇怪了,空格是区别于 null 的单独的存在嘛,空格虽然不是 null 但也不会进!=null 的条件

回复了 cway 创建的主题 程序员 一个炒鸡简单的 SQL 为什么执行没返回结果??
首先感谢大家 回去我测试了下 @az402
@Coande
@congeec 跟条件貌似没关系,单引号也是没影响,只是发现用非日期字符串例如非 yyyy-MM-dd 之类的字符串识别不了,虽然<=2012 但是返回值把所有记录全返回了。但是<='2012-12-31'就没问题
@watzds 也不是瞎写的,去掉转义符跟外面引号肯定可以,mybatis plus 中 gt 条件传 Date 类型数据会自动转成这种带转义的形式,后来我直接传字符串了
@tomczhen
@Juszoe 亲自试验下会发现 time <= '2018-02-01' 这种也是可以的 之前我也怀疑,
@skull @littlewing 感谢

回复了 cway 创建的主题 Java mybatis plus 报错求助 百度没百到求助
@jinue9900 明显不是,是导 jar 包的 ssm 工程,虽然落后了点但是只能这样
@MotherShip 所以不知道什么问题呀

回复了 cway 创建的主题 Java mybatis plus 报错求助 百度没百到求助
@dovme 都加了,Mapper 中也加了 @Mapper 注解

@fooving baseMapper 是 mybatis plus 自己的代码吧

@wc951 就是不知道哪里出错了呀

发现个奇怪的问题,我用 SpringBoot 用之前代码没问题,,但是我换成普通 lib 中放 jar 形式的项目就不行,同样的代码。
2019-07-02 08:46:32 +08:00
回复了 cway 创建的主题 程序员 Mybatis Plus 可以不用 maven 用普通 jar 包形式使用么?
@shangfabao 但是为什么我看别人依赖只导入了 mybatis-plus 的依赖,其他的都没导,是有什么神奇的操作么
