构造器详细资料

方法详细资料

• forward

  public void forward​(ServletRequest request,
                      ServletResponse response)

  从接口复制的说明: javax.servlet.RequestDispatcher
  Forwards a request from a servlet to another resource (servlet, JSP file, or HTML file) on the server. This method allows one servlet to do preliminary processing of a request and another resource to generate the response.

  For a RequestDispatcher obtained via getRequestDispatcher(), the ServletRequest object has its path elements and parameters adjusted to match the path of the target resource.

  forward should be called before the response has been committed to the client (before response body output has been flushed). If the response already has been committed, this method throws an IllegalStateException. Uncommitted output in the response buffer is automatically cleared before the forward.

  The request and response parameters must be either the same objects as were passed to the calling servlet's service method or be subclasses of the ServletRequestWrapper or ServletResponseWrapper classes that wrap them.

  This method sets the dispatcher type of the given request to DispatcherType.FORWARD.

  指定者:

  forward 在接口中 RequestDispatcher

  参数:

  request - a ServletRequest object that represents the request the client makes of the servlet

  response - a ServletResponse object that represents the response the servlet returns to the client

• include

  public void include​(ServletRequest request,
                      ServletResponse response)

  从接口复制的说明: javax.servlet.RequestDispatcher
  Includes the content of a resource (servlet, JSP page, HTML file) in the response. In essence, this method enables programmatic server-side includes.

  The ServletResponse object has its path elements and parameters remain unchanged from the caller's. The included servlet cannot change the response status code or set headers; any attempt to make a change is ignored.

  The request and response parameters must be either the same objects as were passed to the calling servlet's service method or be subclasses of the ServletRequestWrapper or ServletResponseWrapper classes that wrap them.

  This method sets the dispatcher type of the given request to DispatcherType.INCLUDE.

  指定者:

  include 在接口中 RequestDispatcher

  参数:

  request - a ServletRequest object that contains the client's request

  response - a ServletResponse object that contains the servlet's response

  ServletRequest.getDispatcherType()

• getMockHttpServletResponse

  protected MockHttpServletResponse getMockHttpServletResponse​(ServletResponse response)

  Obtain the underlying MockHttpServletResponse, unwrapping HttpServletResponseWrapper decorators if necessary.
