预期返回值

{
    "data": {
        "access_token": "2e9a8ead-3792-4eb1-a1de-e96fc2811920",
        "token_type": "bearer",
        "refresh_token": "93d4761b-393d-4fa7-9a4f-7180f57b88d7",
        "expires_in": 3012,
        "scope": "app"
    },
    "code": 0,
    "msg": ""
}

但是返回值为

{
"code":0,
"data":{
"additionalInformation":{},
"expiration":1596121544910,
"expired":false,
"expiresIn":21599,
"refreshToken":{
"expiration":1596143144910,
"value":"18c8129a-3fe5-4a1a-8922-989d0ba5e165"
},
"scope":["app"],
"tokenType":"bearer",
"value":"3f1b1960-183c-4f94-af0e-0ec5ef99edb4"
},
"msg":""
}

原因
返回时使用fastjson而不是默认的Jackson
