Java String.valueOf(jsonArray) 将 jsonArray 中的 UTF-8 编码内容变成问号

Question

I have this json array (of type JSONArray) containing utf-8 encoded strings:

    [{
      "success":true,
      "data":[
         {"moduleTitle":"تست",
          "title":"تست دو"}
       ],
       "status":200
    }]

And then I would like to get the string value of it.

String s = String.valueOf(jsonArray);

but the utf-8 strings will be turned into question marks like this:

"[{ "success":true, "data":[ {"moduleTitle":"???", "title":"??? ??"} ], "status":200 }]"

how can I make it show the strings correctly?

Answer 1

You are converting the data using the JVM's default charset, UTF-8 charset most probably is not on your server or local.

Try using this:

String s = String.valueOf(jsonArray);
String string2 = new String(s.getBytes(),"UTF-8");
return new ResponseEntity<String>(string2, HttpStatus.OK);
