orcal特殊字符转义：

  • &用 ||&||或者||char(38)||
  • 转义用escape：例如： 'QA/%'escape '/'
  • 直接使用 set define off

include标签和include指令

  • include指令在加载文件时动态包含，先编译在包含
  • .jsp:include 标签是在执行时才对加载的文件进行处理，因此Jsp页面和它所加载的文件在逻辑和语法上都是独立的，如果对加载文件进行修改，那么运行时可以看到所加载文件修改后的结果

记一组错误

escription:

The bean 'shards', defined in class path resource [com/jt/config/Shards.class], could not be registered. A bean with that name has already been defined in file [E:\源码\培优\京淘\day08\jt\jt-common\target\classes\com\jt\config\Shards.class] and overriding is disabled.

Action:

Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true
