spring+JAX-RS实现Restfull接口 demo
JAX-RS是JAVA EE6 引入的一个新技术。 JAX-RS即Java API for RESTful Web Services，是一个Java 编程语言的应用程序接口，支持按照表述性状态转移（REST）架构风格创建Web服务。JAX-RS使用了Java SE5引入的Java注解来简化Web服务的客户端和服务端的开发和部署。
JAX-RS提供了一些注解将一个资源类，一个POJO Java类，封装为Web资源。
@Path，标注资源类或者方法的相对路径
@GET，@PUT，@POST，@DELETE，标注方法是HTTP请求的类型。
@Produces，标注返回的MIME媒体类型
@Consumes，标注可接受请求的MIME媒体类型
@PathParam，@QueryParam，@HeaderParam，@CookieParam，@MatrixParam，@FormParam,分别标注方法的参数来自于HTTP请求的不同位置，例如@PathParam来自于URL的路径，@QueryParam来自于URL的查询参数，@HeaderParam来自于HTTP请求的头信息，@CookieParam来自于HTTP请求的Cookie。
基于JAX-RS实现的框架有Jersey，RESTEasy等。这两个框架创建的应用可以很方便地部署到Servlet 容器中，比如Tomcat，JBoss等。值得一提的是RESTEasy是由JBoss公司开发的，所以将用RESTEasy框架实现的应用部署到JBoss服务器上，可以实现很多额外的功能。
话不多说上例子：
首先需要配置web.xml，其中context-param配置的为spring-mvc.xml在其中import了spring-rs.xml
<import resource="spring-rs.xml"/>
<?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" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
<display-name>myApp</display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
WEB-INF/spring-mvc.xml
</param-value>
</context-param>
<!-- 配置dispatcherServlet -->
<servlet>
<servlet-name>myApp</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring-mvc.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>myApp</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<servlet>
<servlet-name>aaa</servlet-name>
<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
<load-on-startup>2</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>aaa</servlet-name>
<url-pattern>/s/*</url-pattern>
</servlet-mapping>
</web-app>spring-mvc.xml中只需<import resource="spring-rs.xml"/>即可

com.jaxrs.rest.PeopleImp此类中用到的people类就自己写吧！很简单
package com.jaxrs.rest;
import java.util.ArrayList;
import java.util.List;
import javax.jws.WebService;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
//@WebService
@Path("/people")
public class PeopleImp implements IPeople{
@GET//指定请求方式，如果服务端发布的时候指定的是GET（POST），那么客户端访问时必须使用GET（POST）
// @Produces(MediaType.APPLICATION_JSON)//指定服务数据类型
@Path("/query/{id}")//@Path("/query/{id}")就是将“/query”映射到方法上，“{id}”映射到参数上，多个参数，以“/”隔开，放到“{}”中
public People queryPeople(@PathParam(value = "id") String id) {
People p = new People();
if(id.equals("1")){
p.setName("wangqiang");
p.setId(1);
}else{
p.setName("你的id不对");
p.setId(-1);
}
return p;
}
@GET
// @Produces(MediaType.APPLICATION_JSON)
@Path("/queryAll")
public List<People> queryAllPeople() {
List<People> list = new ArrayList<People>();
People p = new People();
p.setName("wangqiang");
p.setId(1);
People p2 = new People();
p2.setName("alsjkhdnoasjkhdlas");
p2.setId(2);
list.add(p);
list.add(p2);
return list;
}
}
