2.编写微信用户基本信息对应类。 
package com.lishidao.app.controller;

        return subscribe;  
    }  
  
    public void setSubscribe(String subscribe) {  
        this.subscribe = subscribe;  
    }  
  
    public String getOpenid() {  
        return openid;  
    }

        this.sex = sex;  
    }  
  
    public String getLanguage() {  
        return language;  
    }  
  
    public void setLanguage(String language) {  
        this.language = language;  
    }  
  
    public String getCity() {  
        return city;  
    }  
  
    public void setCity(String city) {  
        this.city = city;  
    }  
  
    public String getProvince() {  
        return province;

        return headimgurl;  
    }  
  
    public void setHeadimgurl(String headimgurl) {  
        this.headimgurl = headimgurl;  
    }  
  
    public String getSubscribe_time() {  
        return subscribe_time;  
    }  
  
    public void setSubscribe_time(String subscribe_time) {  
        this.subscribe_time = subscribe_time;  
    }  
  
    public String getUnionid() {  
        return unionid;  
    }  
  
    public void setUnionid(String unionid) {  
        this.unionid = unionid;  
    }  
  
    public String toString() {  
        return subscribe + "|" + openid + "|" + nickname + "|" + sex + "|"  
                + language + "|" + city + "|" + province + "|" + country + "|"  
                + headimgurl + "|" + subscribe_time + "|" + unionid;  
    }  
  
}
