加快对接接口开发速度Json转化为实体类

### 1、比如，在对接淘客接口的时候，我们看到接口中给的例子返回了json数据 ###

Json返回示例： 
    { 
    "code": 1, 
    "msg": "SUCCESS", 
    "data": [{ 
    "id": "178", 
    "name": "手机配件狂欢季", 
    "image": "FlfXRXa3NK68Qy8Kvj_QscpMp3xw", 
    "app_image": "FosY6Szk5scmidEkK6tzIqMRM4kR", 
    "cms_image": "FhqJGdrTkCzI56350Ews0zEkMwBT", 
    "content": "——对手机好一点——\n智能时代，手机必不可少\n但是\n保护它的手机壳\n提供能量的充电线等\n也很重要哦ヾ(๑╹◡╹)ﾉ" 
    }] 
    }

### 2、idea安装插件 JsonFormat ###

### 3、自定生成实体类中的字段,需要注意的是，使用下面的`静态内部类存放的list` ###

            }
    
            public String getCmsImage() {
                return cmsImage;
            }
    
            public void setCmsImage(String cmsImage) {
                this.cmsImage = "http://img.haodanku.com/"+cmsImage;
            }
        }
    }

### 4、json转化 ###

HaoDanKuData data  =JsonUtils.toObject(httpBackBean.getResult(), HaoDanKuSelectTopicData.class)  ;
