从Java中的响应中检索状态代码

Question

How to retrieve a response code for an error page? For successful page I am using getresponsecode method. But for an error page, which method I have to use to get a status code of a response of web application?

Answer 1

HttpServletResponse.getStatus() is the one you're looking for. It is not just for error pages, it is for every servlet responses.

The HttpServletResponse class contains constants for the possible values, eg

• HttpServletResponse.SC_OK for success (200)
• HttpServletResponse.SC_BAD_REQUEST for indicating a bad request (400)

Answer 2

httpServletResponse.getStatus() will give you an int value which represents the status code. Open HttpServletResponse class an you ll find the list of the possible status codes
