本文主要是介绍最简的restful webservice实现，提供get和post服务(提供war包下载)，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
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。
