servletrest

A simple, light-weighted, easy-to-use restful servlet framework for JAVA.

it is very simple to configure restservlet, including 2 steps:

step 1: configure restservlet in web.xml to handle all the requests with a common prefix of the url, for example: http://foo.com/foo/rest/*

	<servlet>
		<servlet-name>RestServlet</servlet-name>
		<servlet-class>cn.com.seegoo.servletrest.RestServlet</servlet-class>
		<init-param>
			<param-name>ServletConfig</param-name>  
			<param-value>/servletconfig.xml</param-value>  
		</init-param> 
		<init-param>
			<param-name>Encoding</param-name>  
			<param-value>UTF-8</param-value>  
		</init-param>
		<load-on-startup>1</load-on-startup>     
	</servlet>
	<servlet-mapping>   
		<servlet-name>RestServlet</servlet-name>
		<url-pattern>rest/</url-pattern>
	</servlet-mapping>

step2: create some url patterns in a file named servletconfig.xml to match request url with a certain servlet class. save servletconfig.xml in the root source folder which means servletconfig.xml will be copied in WEB-INF/classes.

	<?xml version="1.0" encoding="UTF-8"?>
	<servlets>
	<!--sample start -->
	<!-- this means HelloServlet will handle the url http://foo.com/foo/rest/hello -->
	<servlet class="com.foo.HelloServlet">
		<urlpattern value="/rest/hello"></urlpattern>
	</servlet>
	<!-- someone is a variable in url pattern whose value will be set to servlet instance's field with the same name "someone".-->
	<!-- for expample,http://foo.com/foo/rest/hello/john, you can get "john" in HelloToSomeoneServlet's field someone-->
	<servlet class="com.foo.HelloToSomeoneServlet">
		<urlpattern value="/rest/hello/{someone}"></urlpattern>
	</servlet>
	<!--sample end -->
	</servlets>
