我能解析到status数据，就是解析不到163对象下的数据，解析到163时报空指针异常
{
"status": 200,
"msg": "操作成功",
"data": {
"163": {
"section1": {
"field_photo": {
"field": "photo",
"label": "图片上传",
"type": "image",
"require": "1",
"vid": "",
"keyboard": "",
"order": ""
}
}
}
}
}
bean类写的正确吗，data对象里包含163对象 163对象里包含section1对象,section1中又包含field_photo对象，每个对象都需要有对应的bean类
