1.建立maven webapp工程aty-rest。

2. 在pom文件增加spring框架、jax-rs接口、CXF实现

<dependency><groupId>javax.ws.rs</groupId><artifactId>javax.ws.rs-api</artifactId><version>2.0</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-web</artifactId><version>3.1.1.RELEASE</version></dependency><dependency><groupId>org.apache.cxf</groupId><artifactId>cxf-rt-frontend-jaxrs</artifactId><version>3.0.0</version></dependency>

3.编写rest接口和实现类

public interface INameService{    @GET    @Path("/welcome/")    @Produces(MediaType.APPLICATION_JSON)    public String welcome();}// @Component("nameServiceImpl")public class NameServiceImpl implements INameService{    public String welcome()    {        return "{\"name\":123}";    }}

4.web.xml中启动sping和cxf

<!-- Spring --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:spring.xml</param-value></context-param><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- CXF --><servlet><servlet-name>cxf</servlet-name><servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class></servlet><servlet-mapping><servlet-name>cxf</servlet-name><url-pattern>/rest/*</url-pattern></servlet-mapping>

4.配置cxf-spring.xml，并在spring.xml中将其包含进去

<?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"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://cxf.apache.org/jaxrshttp://cxf.apache.org/schemas/jaxrs.xsd"><jaxrs:server address="/greet"><jaxrs:serviceBeans><ref bean="nameServiceImpl"/></jaxrs:serviceBeans></jaxrs:server></beans>

5.用maven打包，将war部署到tomcat下。

一切正常即可通过http://127.0.0.1:8080/aty-rest/rest/greet/welcome访问我们发布的rest服务。
