如何使用java解析带有UTF-8字符的json字符串？

Question

I have a json string with SUBSTITUTE () utf-8 character. I'm getting parsing exception when I try to convert json string to java object using jackson. Can you please let me know how to encode and decode utf-8 characters ?

ObjectMapper mapper = new ObjectMapper();
mapper.readValue(jsonString, MY_DOMAIN_OBJECT.class);

jsonString:

{"studentId":"753253-2274", "information":[{"key":"1","value":"Get alerts on your phone(SUBSTITUTE character is present here. Unable to paste it)To subscribe"}]}

Error:

Illegal unquoted character ((CTRL-CHAR, code 26)): has to be escaped using backslash to be included in string value

Answer 1

Can you try this?

ObjectMapper mapper = new ObjectMapper();
mapper.configure(JsonParser.Feature.ALLOW_UNQUOTED_CONTROL_CHARS, true);
mapper.readValue(jsonString, MY_DOMAIN_OBJECT.class);

I hope it helps you: Javadoc

Feature that determines whether parser will allow JSON Strings to contain unquoted control characters (ASCII characters with value less than 32, including tab and line feed characters) or not. If feature is set false, an exception is thrown if such a character is encountered. Since JSON specification requires quoting for all control characters, this is a non-standard feature, and as such disabled by default.
