I have a method in my Spring controller, in which I am returning an object containing a spring attribute with a value "\\HelloWorld" . To store it into Java String object I have to put escape character, then the string becomes "\\\\HelloWorld" . When I print, that works totally fine and prints "\\HelloWorld" . but when I return it in JSon response, it's returning "\\\\HelloWorld" .
But I want it to return "\\HelloWorld" .
Bellow is the snippet:
@RequestMapping("")
@ResponseBody
public MyDataObject greeting() {
MyDataObject f = new MyDataObject();
f.setMessage("\\HelloWorld");
return f;
}
It's Json response is "message":"\\\\HelloWorld", but I want it "\\HelloWorld".
Note: I don't want to unescape manually specific to that string.
You can use a library such as Jakson and it will internally handle such complexities.
MyDataObject f = new MyDataObject();
f.setMessage("\\HelloWorld");
String payload = new ObjectMapper().writeValueAsString(params);
