Spring MVC-REST POST - Bad Request 400

Question

I am trying to send a request to my service, but it does not work. I get it 400 Bad Request. I have GET requests that work fine in a single controller.

Here is a way:

@RequestMapping(value = "/assign", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE)
    @ResponseBody
    public Form5398Obj arriveTrip(@PathVariable String siteId,
                @RequestBody ErrorMsg anError) throws Exception {

        System.out.println(anError.toString());

    }

The java ErrorMessage class is as follows:

public class ErrorMsg {

    private String code;
    private String msg;
    private String request;

    public ErrorMsg(String code, String msg, String request)
    {
        this.code = code;
        this.msg = msg;
        this.request = request;
    }
    public String getCode() {
        return code;
    }
    public void setCode(String code) {
        this.code = code;
    }
    public String getMsg() {
        return msg;
    }
    public void setMsg(String msg) {
        this.msg = msg;
    }
    public String getRequest() {
        return request;
    }
    public void setRequest(String request) {
        this.request = request;
    }

}

I didn’t configure anything. What else do I need to do to make it work? I am using JavaConfig, do I need to add any bean declarations?

I submit: with Content-Type: application / json

{
                "code" : "101",
                "msg" : "Hello Test",
                "request" : "1"
}
