通过调用笑话列表API获取笑话列表

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;
	}
	
	
}
