response.sendRedirect（）没有正确重定向

Question

I have a response.sendRedirect() in an if statement, linking to a link generated by string.format :

String redirect = String.format("booking?order_id=%d&complete='0'&date='%s'&timePeriod='%s'&totalPrice=%d", intBookingID, date, timePeriod, intTotalPrice);

however this generates a 500 error instead or linking to the requested page, is this because I have used parameters, and If so how else would I do this?

Answer 1

它需要添加/your-web-context/ ahead所需的绝对地址

Answer 2

Http 500 code is Internal Server Error which means that something didn't go well in your server. I recommend you to check your logs and see what's happening.

Answer 3

What are you doing with the string redirect ? You should call HttpServletResponse.sendRedirect() but you must not call setStatus() , setContentType() , setContentLength() , setCharacterEncoding() , getOutputStream() or getWriter() on the HttpServletResponse before or after sendRedirect() as the API says:

If the response has already been committed, this method throws an IllegalStateException.

Is there any additional message in the 500 error page or in the log of the server? 500 (Internal Server Error) is typically an uncaught exception.
