spring mvc rest response json and xml

Question

I have the requirement to return the result from the database either as a string in xml-structure or as json-structure. I\'ve got a solution, but I don\'t know, if this one

Answer 1

Easiest way to do this to get JSON response would be: Using Spring 3.1, you could do as follows

1. In your pom.xml file (hoping you are using a maven project), add maven dependency for jackson-mapper (http://mvnrepository.com/artifact/org.codehaus.jackson/jackson-mapper-asl/1.9.13)

2. Modify your code as follows and test the endpoint on postman:

   @RequestMapping(value = "/content/json/{ids}", method = RequestMethod.GET)
   public @ResponseBody String getContentByIdsAsJSON(@PathVariable("ids") String ids){
       String content = "";
       StringBuilder builder = new StringBuilder();
   
       List list = this.contentService.findContentByListingIdAsJSON(ids);
       if (list.isEmpty()){
           content = "no data found";
           return content;
       }
       for (String json : list){
           builder.append(json + "\n");
       }
   
       content = builder.toString();
       return content;
   }
