How to automatically map JSON to Java Class in Spring Controller


I have got the following code:

public class MyClass {

    String xxx;
    String yyy;

    public String getXxx() {
        return xxx;
    }
    public void setXxx(String xxx) {
        this.xxx = xxx;
    }
    public String getYyy() {
        return yyy;
    }
    public void setYyy(String yyy) {
        this.yyy = yyy;
    }
    public MyClass(String xxx, String yyy) {
        super();
        this.xxx = xxx;
        this.yyy = yyy;
    }

    @Override
    public String toString() {
        return "MyClass [xxx=" + xxx + ", yyy=" + yyy + "]";
    }
}

I also implemented the service:

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;


@Controller
class MyService {

    @RequestMapping(value = "/abc", method = RequestMethod.POST, produces = "application/json")

    public @ResponseBody
    String add(@RequestBody String myClass, HttpServletRequest request,
        HttpServletResponse response) {

        return "Test";
    }

}

When I do an HTTP call with DEV HTTP CLIENT with JSON:

{"xxx":"abc", "yyy":"abc"}

enter image description here

I see an error:

Error 406 NOT_ACCEPTABLE

Is it possible to do it in this way or I have to encode JSON and create a Java Object?


Solution

  • try to add produces="application/json" in @RequestMapping

    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestBody;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    import org.springframework.web.bind.annotation.ResponseBody;
    
    
    @Controller
    class MyService {
    
    @RequestMapping(value = "/abc", method = RequestMethod.POST,produces = "application/json" )
        public @ResponseBody String myMethod( @RequestBody String _json,HttpServletRequest request,
            HttpServletResponse response) {
            return _json;
        }   
    }
    

    this the result with postman extension for chrome
