Java String.valueOf(jsonArray) 将 jsonArray 中的 UTF-8 编码内容变成问号 [英] Java String.valueOf(jsonArray) turns UTF-8 encoded content from jsonArray into question marks

问题描述

我有一个包含 utf-8 编码字符串的 json 数组(JSONArray 类型):

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

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

然后我想获取它的字符串值.

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

String s = String.valueOf(jsonArray);

但是utf-8字符串会变成这样的问号:

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

"[{成功":真，数据":[{模块标题":???"，标题":?????"}],状态":200}]"

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

如何让它正确显示字符串?

how can I make it show the strings correctly?

推荐答案

您正在使用 JVM 的默认字符集转换数据，UTF-8 字符集很可能不在您的服务器或本地.

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

试试这个:

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