Question

我需要你的帮助。问题是：

tomcat在<session-timeout>结束
用户点击应用
我们收到错误：

 java.lang.IllegalStateException

喜欢它内部工作：只有某些操作才能重现错误。例如，此网址重现问题

localhost:8080/myapp/editPromotion?promoId=TestBes

而这个不是

localhost:8080/myapp/searchCustomerHome

拦截器对这些网址的工作方式相同

public String intercept(ActionInvocation invocation) throws Exception {
    if (!isLoginAction(invocation)) {
        Map<String, Object> sessionMap = ActionContext.getContext().getSession();

        if (sessionMap.get(LoginAction.USER_NAME) == null) {
            return "notAuthenticated";
        }
    }

    return invocation.invoke();
}

并返回“notAuthenticated”。

另外我在struts.xml中有这段代码：

    <global-results>
         <result name="notAuthenticated" type="redirect">login</result>
    </global-results>

唯一的差异错误请求转到

org.apache.struts2.interceptor.MessageStoreInterceptor.java

并开始运行

public String intercept(ActionInvocation invocation) throws Exception {
    LOG.debug("entering MessageStoreInterceptor ...");

    before(invocation);
    String result = invocation.invoke();
    after(invocation, result);

    LOG.debug("exit executing MessageStoreInterceptor");
    return result;
}

我不知道为什么他们的工作如此不同。

Answer 1

我遇到了同样的问题 - 一切都很好，直到会话超时，取决于请求的操作，我会看到这个例外。

我通过添加＆＃34; createSession＆＃34;解决了这个问题。拦截器作为行动中的第一个拦截器，它解决了这个问题。
