能够快速做出web service的jersey框架。

1. maven dependency

	<!-- jersey -->
		<dependency>
			<groupId>javax.ws.rs</groupId>
			<artifactId>javax.ws.rs-api</artifactId>
			<version>2.0</version>
			<scope>provided</scope>
		</dependency>

		<dependency>
			<groupId>com.sun.jersey</groupId>
			<artifactId>jersey-server</artifactId>
			<version>1.8</version>
		</dependency>

		<dependency>
			<groupId>com.sun.jersey</groupId>
			<artifactId>jersey-json</artifactId>
			<version>1.8</version>
		</dependency>
		<dependency>
			<groupId>com.sun.jersey</groupId>
			<artifactId>jersey-core</artifactId>
			<version>1.8</version>
		</dependency>
	<!-- jersey client -->
		<dependency>
			<groupId>com.sun.jersey</groupId>
			<artifactId>jersey-client</artifactId>
			<version>1.8</version>
		</dependency>

	<!-- servlet -->
		<dependency>
			<groupId>javax.servlet</groupId>
			<artifactId>servlet-api</artifactId>
			<version>2.5</version>
			<type>jar</type>
			<scope>compile</scope>
		</dependency>

2. web.xml

	<servlet>
		<servlet-name>jersey-servlet</servlet-name>
		<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
		<init-param>
			<param-name>com.sun.jersey.config.property.packages</param-name>
			<param-value>com.jersey.resources</param-value>
		</init-param>
		<init-param>
			<param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
			<param-value>true</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>

	<servlet-mapping>
		<servlet-name>jersey-servlet</servlet-name>
		<url-pattern>/jersey/*</url-pattern>
	</servlet-mapping>

3. add one entity in the package:

package com.jersey.entity;
public class User{
	private int id;
	private String name;
	
public void setId(int id){
		this.id = id;
	}
public int getId(){
		return id;
	}
public void setName(String name){
		this.name = name;
	}
public String getName(){
		return name;
	}
}

4. add one resources :

package com.jersey.resources;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

import com.jersey.User;
@Path("/user")
public class UserResources {
	@GET
	@Path("/id/{id}")
	@Produces(MediaType.APPLICATION_JSON)
	public Staff getStaffById(@PathParam("id") int id) {
		User user = new User();
		user.setId(id);
		user.setName("name1");
		return user;
	}

}

5. url : project/jersey/user/2

return the json object
