com.fasterxml.jackson.core.JsonParseException：读取json文件时出现意外字符（代码160）

Question

I am reading the below json content from a file and converting into a map but i am getting the below exception. Kindly let me know if anybody has come across such issue. I validated my json content and looks valid. Not sure why this error.

Json Content:

{
    "Results":[{         
        "TotalPositiveFeedbackCount": 0      
    },{
        "TotalPositiveFeedbackCount": 1      
    }   ]
}

Code:

Map<String, Object> domainMap = new HashMap<String, Object>();
try {
    responseJson = getFile("reviewresponse.json");
    //responseJson = new String(Files.readAllBytes(Paths.get("reviewresponse.json")), StandardCharsets.UTF_8);
    ObjectMapper jsonObjectMapper = new ObjectMapper();
    jsonObjectMapper.configure(JsonParser.Feature.ALLOW_UNQUOTED_FIELD_NAMES, true);
    domainMap = jsonObjectMapper.readValue(responseJson,
                   new TypeReference<Map<String, Object>>() {});
} 

Exception Details:

com.fasterxml.jackson.core.JsonParseException: Unexpected character (' ' (code 160)): was expecting either valid name character (for unquoted name) or double-quote (for quoted) to start field name

Answer 1

Your JSON content contains non-breaking spaces (character code 160, commonly known as   ) likely from copying and pasting JSON (usually from a webpage) that used   to indent the JSON.

You can fix it with

responseJson = responseJson.replace('\u00A0',' ');
