In your struts2 config file you can configure global exceptions like

<global-exception-mappings>
    <exception-mapping exception="org.springframework.security.access.AccessDeniedException" result="securityerror" />
     <exception-mapping exception="java.lang.Exception" result="error" />
   </global-exception-mappings>

  <global-results>
        <result name="securityerror">/securityerror.jsp</result>
    <result name="error">/error.jsp</result>
   </global-results>

如果你发现细微的例外情况,处理你可以确定的行动等级,则会达到申请水平。

<action name="actionspecificexception" class="org.apache.struts.register.action.Register" method="throwSecurityException">
     <exception-mapping exception="org.springframework.security.access.AccessDeniedException" 
          result="login" />
      <result>/register.jsp</result>
      <result name="login">/login.jsp</result>
   </action>

因此,这取决于你们选择如何混淆。详见下文。

我建议不要把一切例外当作一个 raw子,更好地制造你自己的例外,在其中总结这种例外情况,将有助于你更好地组织你的法典。

Hope this will help you.
