Jersey RESTful WebService框架是一个开源的、产品级别的JAVA框架，支持JAX-RS API并且是一个JAX-RS(JSR 311和 JSR 339)的参考实现

Jersey不仅仅是一个JAX-RS的参考实现，Jersey提供自己的API，其API继承自JAX-RS，提供更多的特性和功能以进一步简化RESTful service和客户端的开发

下面简单介绍一下其客户端、服务端的实现逻辑

客户端Test.java

package com.ardo.client;
    
    import javax.ws.rs.core.MediaType;
    import javax.ws.rs.core.MultivaluedMap;
    
    import org.codehaus.jettison.json.JSONException;
    import org.codehaus.jettison.json.JSONObject;
    
    import com.ardo.bean.Info;
    import com.ardo.bean.Student;
    import com.sun.jersey.api.client.Client;
    import com.sun.jersey.api.client.WebResource;
    import com.sun.jersey.api.client.config.ClientConfig;
    import com.sun.jersey.api.client.config.DefaultClientConfig;
    import com.sun.jersey.api.json.JSONConfiguration;
    
    public class Test {
    	
    	private Client client ;
    	
    	/**
    	 * 初始化jersey客户端
    	 */
    	public void init(){
    		if(client==null){
    			ClientConfig config = new DefaultClientConfig();
    			config.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING, true);
    			client = Client.create(config);
    			client.setConnectTimeout(3000);
    		}
    	}
    	
    	public Info get(String url, String path, MultivaluedMap<String, String> queryParams){
    		try {
    			return queryParams == null?client.resource(url).path(path).type(MediaType.APPLICATION_JSON).get(Info.class):
    				client.resource(url).queryParams(queryParams).path(path).type(MediaType.APPLICATION_JSON).get(Info.class);
    		} catch (Exception e) {
    			e.printStackTrace();
    		}
    		return null;
    	}
    	
    	public String getString(String url, String path, MultivaluedMap<String, String> queryParams){
    		try {
    			return queryParams == null?client.resource(url).path(path).type(MediaType.APPLICATION_JSON).get(String.class):
    				client.resource(url).queryParams(queryParams).path(path).type(MediaType.APPLICATION_JSON).get(String.class);
    		} catch (Exception e) {
    			e.printStackTrace();
    		}
    		return null;
    	}
    	
    	/**
    	 * 客户端请求【get方式-返回实体对象|字符串】
    	 * @param args
    	 */
    	public static void main(String[] args) {
    		Test test = new Test();
    		test.init();
    		//Info info = test.get("http://localhost:8899/", "jersey/services/hello/get/Tom", null);
    		//System.out.println("请求返回："+info.getCode()+" "+info.getName());
    		
    		String info = test.getString("http://localhost:8899/", "jersey/services/hello/get/Tom", null);
    		System.out.println("请求返回："+info);
    	}
    	
    	/**
    	 * 客户端请求【post方式】
    	 * @param argc
    	 * @throws JSONException
    	 */
    	public static void main4(String[] argc) throws JSONException {  
            Client c = Client.create();  
            WebResource r=c.resource("http://localhost:8899/jersey/services/hello/getpost");  
            JSONObject obj = new JSONObject();  
            obj.put("name", "张晓梅2331");  
            obj.put("school", "华北大学2342");  
            JSONObject response = r.type(MediaType.APPLICATION_JSON_TYPE).post(JSONObject.class, obj);     
            System.out.println(response.toString());         
        } 
    }

服务端 ArdoService.java

示例代码中展示了多种方式：get、post、文本、xml、json、多路径参数、多动态参数匹配等
