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<jokeSon> 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<jokeSon> getDetail() {
		return detail;
	}
	public void setDetail(List<jokeSon> 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;
	}
    
    
    
    
    
}
