不行，导航跟国内导航路线有点不一致，我感觉可能是某些路线未更新。

国企的话，报 500w
私企的话，顶多 20w

年后千万不要换机！至少要等到中旬，现在换机半年后铁定降千元
今年是 5G 第二年，并且 5G 手机价格会越来越便宜，另外骁龙 865 发布
何不在等等

告诉别人自己是打字员

一周吧，有基础

很多 SAP ERP 系统都还是用 WebService 呢
国企最多

两年，你知道猪肉涨到多少钱了么？

加了几个条件又进去了，晚上下班回去研究下这个问题

@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

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

技校毕业在富士康干了两年……

@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

@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。
