Java / JSON.simple - printing backslash before slash

I'm printing some data into a json file through Java and JSON.simple library, but I'm getting a backslash added whenever a ther's a slash as in:

"thing":[
     {"file":"Screenshot_from_2018-07-12_14-41-19.png",
      "currentDateTime":"02\/08\/2018 15:11:14",
      "selectedDate":"02\/08\/2018",
      "uri":"\/var\/stuff\/files\/Screenshot_from_2018-07-12_14-41-19.png",
      "user":"user"}
 ]

It happens at the moment when we pass the map on to the JSONObject:

        map.put("file", fileNameFormat);
        map.put("uri", filesPath + "/" + service + "/" + fileNameFormat);
        map.put("user", user);
        map.put("selectedDate", selectedDate);
        map.put("currentDateTime", currentDateTime);
        JSONObject json = new JSONObject(map); //HERE

I think it's going to be a problem when I further develop the utility. Why does it happen and how do I walk around it? Thanks in advance.

Solution

  • This is done to allow json strings inside scripts tags, as this question explains:

    JSON: why are forward slashes escaped?

    On the javascript side it will be read as intended.
    '\/' === '/' in JavaScript, and JSON is valid JavaScript.

    To handle everything in Java, Gson could be used. Please check the link to use Gson for converting Json to objects: Json to Java objects
