struts2 常量配置详解

1，struts.action.extension

作用：设置为htm的时候， 把url后缀为htm的映射成为action

源码：org.apache.struts2.dispatcher.mapper.DefaultActionMapper

?

Java代码 ?收藏代码
  1. @Inject (StrutsConstants.STRUTS_ACTION_EXTENSION)??
  2. ????public ? void ?setExtensions(String?extensions)?{??
  3. ????????if ?(extensions?!=? null ?&&?! "" .equals(extensions))?{??
  4. ????????????List<String>?list?=?new ?ArrayList<String>();??
  5. ????????????String[]?tokens?=?extensions.split("," );??
  6. ????????????for ?(String?token?:?tokens)?{??
  7. ????????????????list.add(token);??
  8. ????????????}??
  9. ????????????if ?(extensions.endsWith( "," ))?{??
  10. ????????????????list.add("" );??
  11. ????????????}??
  12. ????????????this .extensions?=?Collections.unmodifiableList(list);??
  13. ????????}?else ?{??
  14. ????????????this .extensions?=? null ;??
  15. ????????}??
  16. ????}??

?从源代码得知，这个可以用配置可以用“,”分割

?

2，struts.enable.DynamicMethodInvocation

作用：动态调用action方法，action!method

源码：org.apache.struts2.dispatcher.mapper.DefaultActionMapper

?

?

?

Java代码 ?收藏代码
  1. if ?(allowDynamicMethodCalls)?{??

  7. ????????????????mapping.setMethod(name.substring(exclamation?+?1 ));??
  8. ????????????}??
  9. ????????}??
  10. ????????return ?mapping;??

  19. ????????????}??
?

10，struts.url.https.port 同上，差不多。

?

11，struts.url.includeParams

作用：不够详细的介绍

none： 在ServletUrlRenderer渲染URL的时候不会把参数带进去?

不推荐使用这个，改为使用 struts.freemarker.mru.max.strong.size >0 ? ? ? ? ? ? ? ? struts.freemarker.templatesCache.updateDelay>0

?

21，struts.freemarker.templatesCache.updateDelay

作用：设置正整数和0 几秒钟更新一次freemarket模板
