用jersey写 java restfull web services 输出xml格式数据

 1 logic

package com.toic.rest;



import com.toic.model.Folder;



import java.util.logging.Logger;



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 javax.ws.rs.core.Response;



@Path("/folders")

    private Logger logger = Logger.getLogger(RESTService.class.getName());



    public RESTService() {

        super();

    }

    // 这个 成功  http://localhost:7001/RESTfull001/folders/sayhello/li

    @GET

    @Path("sayhello/{name}")

    @Produces("text/plain")

    public String removeStudent(@PathParam("name") String name) {

        String say = name + " said hello!";

        return say;

    }



     //http://localhost:7001/RESTfull001/folders/guid/000234

    @GET

    @Path("/guid/{folderguid}")

    //@Produces({MediaType.APPLICATION_XML })

    @Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })

    

    public Folder getFoldersByGUID(@PathParam("folderguid") String folderguid) {



        

//        第一种    

        Folder folder = Folder.makeFolders();

        

        if(!folderguid.equals("0")){

            

            for(int i=0;i<folder.getChildFolders().size();i++){

                

                if(((Folder)folder.getChildFolders().get(i)).getFolderGUID().equals(folderguid)){

                    

                    folder=(Folder)folder.getChildFolders().get(i);

                }

                

            }

            

        }

//        rootFolder.setOwner("juan");

//        rootFolder.setFolderGUID("000234");

//        rootFolder.setFolderType("NATIVE");

//        return rootFolder;

        

        

        ////return Response.status(Response.Status.OK).entity(folder).build();

    }

    

    public static void main(String s[]){

        System.out.println(new RESTService().getFoldersByGUID("00") );
//调用方法

//或者在浏览器输入URL    http://localhost:7001/RESTfull001/folders/guid/000234

//或者下面在java代码中调用

/////////////////////////////////////////////////////////
// //需要导入下面的lib中jar Oracle\Middleware\Oracle_Home\wlserver\server\lib
// System.out.println("**** ****");
// Client client = ClientBuilder.newClient().register(JacksonJsonProvider.class);// 注册json 支持
// WebTarget target = client.target(url + "/guid/000234");
// Response response = target.request().get();
// Folder folder = response.readEntity(Folder.class);
// System.out.println(folder.getFolderName()+" "+folder.getFolderGUID()+" "+folder.getFolderType()+" "+folder.getOwner());
// response.close();
//
// //打印
// //**** ****
// // Root Folder 000234 NATIVE juan
/////////////////////////////////////////////////////////

 

//或者如下调用

//com.sun.jersey.api.client.Client client = com.sun.jersey.api.client.Client .create();

//Folder folder =client.resource(url + "/guid/" + "200234").accept(MediaType.APPLICATION_XML_TYPE).get(Folder.class);

//System.out.println(folder.getFolderGUID()+" "+folder.getFolderName()+" "+folder.getFolderType()+" "+folder.getOwner());
//200234 Folder2 NATIVE xiaolu
