interceptorstack

问题 My code downloads a file from back-end server. Since we will be retrieving records numbering in millions, we have used Struts2 execAndWait Interceptor. To test this, we are inserting delay of 30 secs. I am able to download file without inserting delay (where test data very small), but after inserting it, i never get the file. Logs show that action class is being repeatedly executed due to <meta-refresh> of 5 secs in wait file, even input-stream is populated. What could be the reason for such

问题 I want to be able to disable form validation for one action in Struts 2, but have the rest of the interceptor stack still be able to run. I have an interceptor that checks to see if the user is logged in, which I always want execute, but for some actions (inputting information, for instance), I don't want the action's validate to be called. I tried doing something like the following: <interceptors> <interceptor name="bankingAuthenticator" class="csc309.a4.banking.BankUserAuthenticator"/>

问题 First of all I use simple theme but even without it the same behaviour occurs (except page formatting). When I submit the form, name field gets empty and redirects to register.jsp without displaying the validation error. After checking the logs or with debugger, it seems that validation is working properly and server log messages are written as expected. I'll post generic code. struts.properties struts.ui.theme=simple MyAction private User user = new User() // getter and setter @Inject
