1. 在Eclipse中新建一个Maven的Web项目，其中红色部分为要修改的文件

2. 在pom.xml中引入Jersey的依赖项:

<!-- 引入 Jersey的相关依赖项 --><dependency><groupId>com.sun.jersey</groupId><artifactId>jersey-server</artifactId><version>1.19</version></dependency><dependency><groupId>com.sun.jersey</groupId><artifactId>jersey-servlet</artifactId><version>1.19</version></dependency>

3. 编写RESTful的资源类HelloWorldResource.java

package restful.res;import javax.ws.rs.GET;import javax.ws.rs.Path;import javax.ws.rs.Produces;/** * The Java class will be hosted at the URI path "/helloworld" *  * @author hp *  */@Path("/helloworld")public class HelloWorldResource {// The Java method will process HTTP GET requests@GET// The Java method will produce content identified by the MIME Media// type "text/plain"@Produces("text/plain")public String getClichedMessage() {// Return some cliched textual contentreturn "Jersey Hello World";}}

4. 在web.xml中添加对Jersey支持的Servlet:

<!-- 引入支持Jersey的Servlet容器 --><servlet><servlet-name>JerseyFirstServlet</servlet-name><servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class><init-param>    <!-- 设置REST资源所在的包(可选) --><param-name>com.sun.jersey.config.property.packages</param-name><param-value>restful.res</param-value></init-param></servlet><servlet-mapping><servlet-name>JerseyFirstServlet</servlet-name><url-pattern>/restful/*</url-pattern></servlet-mapping>

5. 用Maven打成war包并部署到Tomcat中进行测试

在浏览器中输入http://localhost:8080/JerseyFirst/restful/helloworld

测试成功！
