Class HttpRequestHandlerServlet

java.lang.Object

javax.servlet.GenericServlet

javax.servlet.http.HttpServlet

org.springframework.web.context.support.HttpRequestHandlerServlet

All Implemented Interfaces:

java.io.Serializable, Servlet, ServletConfig

public class HttpRequestHandlerServlet
extends HttpServlet

Simple HttpServlet that delegates to an HttpRequestHandler bean defined in Spring's root web application context. The target bean name must match the HttpRequestHandlerServlet servlet-name as defined in web.xml.

This can for example be used to expose a single Spring remote exporter, such as HttpInvokerServiceExporter or HessianServiceExporter, per HttpRequestHandlerServlet definition. This is a minimal alternative to defining remote exporters as beans in a DispatcherServlet context (with advanced mapping and interception facilities being available there).

Method Detail

init

public void init()
          throws ServletException

Description copied from class: javax.servlet.GenericServlet

A convenience method which can be overridden so that there's no need to call super.init(config).

Instead of overriding GenericServlet.init(ServletConfig), simply override this method and it will be called by GenericServlet.init(ServletConfig config). The ServletConfig object can still be retrieved via GenericServlet.getServletConfig().

Overrides:

init in class GenericServlet

Throws:

ServletException - if an exception occurs that interrupts the servlet's normal operation

service

protected void service(HttpServletRequest request,
                       HttpServletResponse response)
                throws ServletException,
                       java.io.IOException

Description copied from class: javax.servlet.http.HttpServlet

Receives standard HTTP requests from the public service method and dispatches them to the doXXX methods defined in this class. This method is an HTTP-specific version of the Servlet.service(javax.servlet.ServletRequest, javax.servlet.ServletResponse) method. There's no need to override this method.

Overrides:

service in class HttpServlet

Parameters:

request - the HttpServletRequest object that contains the request the client made of the servlet

response - the HttpServletResponse object that contains the response the servlet returns to the client

Throws:

ServletException - if the HTTP request cannot be handled

java.io.IOException - if an input or output error occurs while the servlet is handling the HTTP request
