<p>????? 本文目的就项目中的Apache CXF中的REST WebService风格的展现。下面言归正传，看实惠，代码如下：

package com.easyway.rest.webservice;import javax.ws.rs.Consumes;import javax.ws.rs.GET;import javax.ws.rs.POST;import javax.ws.rs.Path;import javax.ws.rs.Produces;import javax.ws.rs.core.Context;import javax.ws.rs.core.MediaType;import org.apache.cxf.jaxrs.ext.MessageContext;/** * Apache CXF REST方式发布WebService的总结 * 1.定义Apache CXF CXFServlet的服务发布拦截类 * org.apache.cxf.transport.servlet.CXFServlet; * 2.定义相关REST WebService的服务类 * RestWebService * 3.在相关的Spring的配置文件配置相关的参数 * <pre> * <import resource="classpath:META-INF/cxf/cxf-all.xml"/> * *<http-conf:conduit name="*.http-conduit">*<http-conf:client ReceiveTimeout="600000" ConnectionTimeout="600000"/><!-- 10分钟 -->*</http-conf:conduit>*** <bean id="RestWSBean" address="/restWS">*<jaxrs:serviceBeans>*<ref bean="restService" />*</jaxrs:serviceBeans>*</jaxrs:server>* </pre> * 4.发布相关的Web服务 * 查看相关的服务： * 例如： * http://localhost:8080/ApacheCXFREST/service/ * ApacheCXFREST为Web项目上下文 * service为Apache CXF在Web.xml容器中配置的拦截路径 * 查看WADL的路径： * http://localhost:8080/ApacheCXFREST/service/restWS?_wadl&_type=xml * ApacheCXFREST为Web项目上下文 * service为Apache CXF在Web.xml容器中配置的拦截路径 * restWS为Spring的中配置的REST服务的拦截的路径 * _wadl&_type=xml为WADL的协议的格式 * * <resources base="http://localhost:8080/ApacheCXFREST/service/restWS"> * <resource path="/rest"> * <method name="GET"> * .............. * 请求的路径=resources元的base属性+resource元素的path属性 * 例如：http://localhost:8080/ApacheCXFREST/service/restWS/rest * 5.请求相关的服务 * 例如 * * @author longgangbai * */@Path("/rest")public class RestWebService {private MessageContext messageContext;/** * 存储发送的数据 * @param messageContext */@Contextpublic void setMessageContext(MessageContext messageContext) {this.messageContext = messageContext;}/** * * 领导慰问士兵们的 * * @param username xx * @return */@GET()@Consumes(MediaType.TEXT_PLAIN)public String helloworld(){return "xx说： 同志们辛苦了 !!

spring关于rest配置如下：
<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jaxrs="http://cxf.apache.org/jaxrs" xmlns:jaxws="http://cxf.apache.org/jaxws" xmlns:http-conf="http://cxf.apache.org/transports/http/configuration" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://cxf.apache.org/jaxrs http://cxf.apache.org/schemas/jaxrs.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd http://cxf.apache.org/transports/http/configuration http://cxf.apache.org/schemas/configuration/http-conf.xsd"> <!-- 针对CXF发布服务的需要的配置的加载的导入 --> <import resource="classpath:META-INF/cxf/cxf-all.xml"/> <!-- 设置服务相关的请求的配置 --> <http-conf:conduit name="*.http-conduit"><http-conf:client ReceiveTimeout="600000" ConnectionTimeout="600000"/><!-- 10分钟 --></http-conf:conduit> <!-- 设置需要发布的bean --> <bean id="RestWSBean" address="/restWS"><jaxrs:serviceBeans><ref bean="RestWSBean" /></jaxrs:serviceBeans></jaxrs:server></beans>

web.xml配置如下：
<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <display-name>RESTWebServices</display-name> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContent-*-services.xml</param-value> </context-param> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> <servlet> <servlet-name>CXFServlet</servlet-name> <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>CXFServlet</servlet-name> <url-pattern>/service/*</url-pattern> </servlet-mapping></web-app>
