最简的restful webservice实现，提供get和post服务(提供war包下载)

 

服务的粒度越小复用度就越高。

 

本文提供一个restlet的最简单的实现。

一、首先实现Get方法和Post方法

1、Get方法

 
package org.soachina.rest.component.resource;

import org.restlet.data.Status;
import org.restlet.representation.Representation;
import org.restlet.representation.StringRepresentation;
import org.restlet.resource.Get;
import org.restlet.resource.ServerResource;

public class GetDemoResource extends ServerResource {

	@Get
	public Representation get() {
		getResponse().setStatus(Status.SUCCESS_OK);
		return new StringRepresentation("*** Get Method Done!");
	}
}

 

2、Post方法

 
package org.soachina.rest.component.resource;

import org.restlet.data.Status;
import org.restlet.representation.Representation;
import org.restlet.representation.StringRepresentation;
import org.restlet.resource.Post;
import org.restlet.resource.ServerResource;

public class PostDemoResource extends ServerResource {
	
	@Post
	public Representation post(String parameters) {
		getResponse().setStatus(Status.SUCCESS_OK);
		return new StringRepresentation("*** Post Method Done!" + parameters);
	}
}
 
 

二、web.xml配置文件

 
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
	<display-name>Restful Webservice Component</display-name>
	<description>Restful Webservice Component</description>

	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>
			classpath:config/application-context.xml
		</param-value>
		<description>Spring config file locations</description>
	</context-param>

	<listener>
	    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

   <servlet>  
      <servlet-name>RestletServlet</servlet-name>  
      <servlet-class>org.restlet.ext.spring.SpringServerServlet</servlet-class>  
      <init-param>   
            <param-name>org.restlet.application</param-name>  
            <param-value>application</param-value>  
      </init-param>  
	  <init-param>  
            <param-name>org.restlet.component</param-name>  
            <param-value>component</param-value>  
      </init-param>  
   </servlet>  
  
 
   <servlet-mapping>  
      <servlet-name>RestletServlet</servlet-name>  
      <url-pattern>/restlet/*</url-pattern>  
   </servlet-mapping>


	<session-config>
		<session-timeout>30</session-timeout>
	</session-config>
	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>
</web-app>
 
 

三、application-context.xml

 
<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'>

<beans>
    <import resource="classpath:config/rest/rest-component-config.xml"/>
    <import resource="classpath:config/extension/*-context.xml"/>
</beans>
  

四、rest-component-config.xml

 
<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'>

<beans>

<!--         
   ==========================           Base Config      =============================
-->

<bean name="component" id="component" autowire="byName" class="org.restlet.ext.spring.SpringComponent">
	<property name="defaultTarget" ref="application" /></bean>

<bean name="application" id="application" class="org.restlet.Application">
    <property name="inboundRoot" ref="router" /></bean>

<bean name="router"	class="org.restlet.ext.spring.SpringBeanRouter" />


<!--         
   ==========================           URL Config      =============================
-->

<bean name="/getdemo" id="get" autowire="byName" class="org.soachina.rest.component.resource.GetDemoResource" />

<bean name="/postdemo" id="post" autowire="byName" class="org.soachina.rest.component.resource.PostDemoResource" />


</beans>
 

五、完整的项目下载

项目是一个zip压缩包，可以直接解压部署在tomcat6.x或者tomcat7.x上。

压缩包中有readme.txt，描述了如何安装、测试和修改。

源代码在上面第一步中提供。
