我有一个自定义拦截器(TransferInterceptor),它检查我的应用程序中的函数更改。当它发生更改时,拦截器返回一个后处理字符串(结果),其中包含我要重定向到的操作的全局结果名称。我在struts.xml文件的全局结果中定义了结果,但它们没有重定向到指定的操作。我有一个“登录”全局结果可以正常工作,但它是从JSP调用的:
<s:a action="Login.action">Login</s:a>
struts.xml文件:
<package name="default" extends="struts-default" namespace="/">
<interceptors>
<interceptor name="AuthenticationInterceptor" class="com.purchasing.utils.AuthenticationInterceptor" />
<interceptor name="TransferInterceptor" class="com.purchasing.utils.TransferInterceptor" />
<interceptor-stack name="secureStack">
<interceptor-ref name="TransferInterceptor" />
<interceptor-ref name="AuthenticationInterceptor" />
<interceptor-ref name="defaultStack" />
</interceptor-stack>
</interceptors>
<default-interceptor-ref name="secureStack" />
<global-results>
<result name="Login">login.jsp</result>
<result name="RESULTA" type="redirect">ACTIONA</result>
<result name="RESULTB" type="redirect">ACTIONB</result>
</global-results>
<action name="Login" class="com.purchasing.actions.Login">
<interceptor-ref name="defaultStack"></interceptor-ref>
<result name="success">welcome.jsp</result>
<result name="error">login.jsp</result>
<result name="input">login.jsp</result>
</action>
<action name="ACTIONA" class="com.purchasing.actions.ACTIONA">
<result name="success">ACTIONA.jsp</result>
<result name="error">ACTIONA.jsp</result>
<result name="input">ACTIONA.jsp</result>
</action>
<action name="ACTIONB" class="com.purchasing.actions.ACTIONB">
<result name="success">ACTIONB.jsp</result>
<result name="error">ACTIONB.jsp</result>
<result name="input">ACTIONB.jsp</result>
</action>
</package>
TransferInterceptor:
public String intercept(ActionInvocation ai) throws Exception
{
String result = ai.invoke();
session = ai.getInvocationContext().getSession();
fl = (FunctionLine) session.get(Constants.FUNCTION_LINE);
function = fl.getFl_function();
last_function = (Integer) session.get(Constants.LAST_FUNCTION);
if (function != last_function) {
session.put(Constants.LAST_FUNCTION, new Integer(function));
switch (function) {
case 61: return "RESULTA";
case 62: return "RESULTB";
}
return "error";
}
else {
return result;
}
}
非常感谢任何帮助!

根据@Lukasz评论:
If you want to redirect to an action use redirectAction result type instead of redirect which is used to redirect to static resources
它仍然无效,因为ACTIONB&amp; ACTIONA从不执行,因为它们通过相同的拦截器堆栈,它返回redirectAction结果&amp;因此,它有点陷入无限循环。
