通过调用笑话列表API获取笑话列表

先写好封装json的实体类:

package com.web.entity;import java.util.List;public class Joke {       private String status;       private String desc;       private List
     
       detail;	public String getStatus() {		return status;	}	public void setStatus(String status) {		this.status = status;	}	public String getDesc() {		return desc;	}	public void setDesc(String desc) {		this.desc = desc;	}	public List
      
        getDetail() {		return detail;	}	public void setDetail(List
       
         detail) {		this.detail = detail;	}		}
       
      
     

package com.web.entity;public class jokeSon {    private int id;    private String xhid;    private String author;    private String content;    private String picUrl;    private String status;	public int getId() {		return id;	}	public void setId(int id) {		this.id = id;	}	public String getXhid() {		return xhid;	}	public void setXhid(String xhid) {		this.xhid = xhid;	}	public String getAuthor() {		return author;	}	public void setAuthor(String author) {		this.author = author;	}	public String getContent() {		return content;	}	public void setContent(String content) {		this.content = content;	}	public String getPicUrl() {		return picUrl;	}	public void setPicUrl(String picUrl) {		this.picUrl = picUrl;	}	public String getStatus() {		return status;	}	public void setStatus(String status) {		this.status = status;	}                    }

       getJoke(){		String requestUrl="http://api.1-blog.com/biz/bizserver/xiaohua/list.do?maxXhid=15602&minXhid=10000&size=5";				 StringBuffer sb=new StringBuffer();	     String json=httpRequest(requestUrl);		 Gson gson=new Gson();	     Joke joke=gson.fromJson(json,Joke.class);	  	     return (List
      
       )joke.getDetail();	}		public static void main(String[] args) {	       List
       
         list=getJoke();	       for(jokeSon jok:list){	    	   System.out.println(jok.getAuthor()+"\n"+jok.getContent()+"\n");	       }	       	       	}	}
