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*
