    操作环境:(1)Tomcat 7.0.72.0

         (2)OS Name: Windows 7

          (3)JVM Version:  1.8.0_25-b18

          (4)eclipse Version: Kepler Service Release 2

         (5)struts2 version:struts2-core-2.5.10.1

    1.通配符访问方法,报错404错误找不到页面

      (1)错误原因:struts.xml中缺少<global-allowed-methods>regex:.*</global-allowed-methods>,根据字面理解就是允许以*通配符的方式访问方法

      (2)详细错误:HTTP Status 404 - There is no Action mapped for namespace [/] and action name [] associated with context path [/struts2002].

      (3)报错截图:

          (4)解决方案:在package标签之间添加<global-allowed-methods>regex:.*</global-allowed-methods>即可

     2.编写struts.xml时编译报错

      (1)错误原因:<package></package>中的标签必须按顺序书写,否则会报错

      (2)详细错误:The content of element type "package" must match "(result-types?,interceptors?,default-interceptor-ref?,default-action-ref?,default-class-ref?,global-results?,global-allowed-methods?,global-exception-mappings?,action*)".

      (3)报错截图:

      (4)解决方案:检查顺序是否正确

              result-types
              interceptors
              default-interceptor-ref
              default-action-ref
              default-class-ref
              global-results
              global-exception-mappings
              action*
