How to remove escape characters when JSON is added to model in spring rest controller

Instead of adding the string to model return JSON directly

@RequestMapping(value="/all")public @ResponseBody String getJson(){   //Logic    return json; }

java json spring rest spring-rest

You can use replaceAll:

String json = serviceDao.getResponseJson();if (json != null && !json.isEmpty()) {    model.addAttribute("result", json.replaceAll("\\\\", ""));}

java json spring rest spring-rest

If you are using spring, you can use @ResponseBody and directly return your class object instead of String.

You can refer example given in this link.

Also don't forget to include maven dependency.

<dependency>    <groupId>org.codehaus.jackson</groupId>    <artifactId>jackson-mapper-asl</artifactId>    <version>1.9.12</version></dependency>
