java拼接json字符串

转义字符 \"表示 "

String json1 = "{\"serviceCode\":" + "\"" +  text11 + "\"" + ", \"appId\":" + "\"" + text12 + "\"" + ",\"appSecret\":" + "\"" + text13 + "\"" + ",\"params\":[{\"sceneAreaId\":" + "\"" + text9 + "\"" + ",\"regulationValue\":" + "\"" + text10 + "\"" + "}]}";


在postman中美化后：

{

    "serviceCode": "1",

    "appId": "1",

    "appSecret": "1",

    "params": [

        {

            "sceneAreaId": "1",

            "regulationValue": "111"

        }

    ]

}
