This is my curl method request maps to POJO that fails with 400:

CURL REQUEST:

curl -v -H "Accept: application/json" -H "Content-type: application/json" -X POST -d     '{"key":"XYZ","uniqueId":"ABCD"}' http://localhost:8080/api/rest/connect/tick/view.json

< Connection: close

APPLICATION-CONFIG.XML:

<context:annotation-config/>
<mvc:annotation-driven/>
followed by, Bean Definitions

CONTROLLER CLASS:

@RequestMapping(value="/tick/view.*", method = RequestMethod.POST, consumes=MediaType.APPLICATION_JSON_VALUE, produces=MediaType.APPLICATION_JSON_VALUE)
@ResponseBody
    public IConnectResponse tickConnectPost(@RequestBody final ConnectServiceBean     connectServiceBean) {

CONNECTSERVICEBEAN:

import java.io.Serializable;
public class ConnectServiceBean implements Serializable {
    private static final long serialVersionUID = 1L;
    private String key;
    private String uniqueId;
    //Getters and setters }

But is working for another method request maps to String:

curl -i -H "Content-Type: application/json" -X POST -d '{"JKL@user.com"}'     http://localhost:8080/api/rest/connect/tick/XYZ/view.json
HTTP/1.1 200 OK

CONTROLLER:

@RequestMapping(value="/tick/{key}/view.*", method = RequestMethod.POST,      consumes="application/json", produces = "application/json; charset=utf-8")
    public IConnectResponse tickConnectPostString (
        @PathVariable("key") String key, @RequestBody String uniqueId
    ) {}

I felt that there is something wrong with Jackson Mapping. But I have all the necessary POM dependencies also I read in some other stackoverflow post where I need only for Jackson configurations for bean mappings(not sure though) org.codehaus.jackson jackson-core-asl 1.9.7
org.codehaus.jackson jackson-mapper-asl 1.9.7

  • what is produces=MediaType.APPLICATION_JSON_VALUE? produces = "application/json; charset=utf-8") should work – Ali.Mojtahed Sep 19 '13 at 20:26
  • Hi Ali, Thanks I changed that as per your suggestion but no luck :( – Pradeep Sep 19 '13 at 20:49
  • Are you trying to ConnectServiceBean stringify it before send? please post ajax method – Ali.Mojtahed Sep 20 '13 at 12:43

    Thanks Ali, As per the link (http://stackoverflow.com/questions/10323957/posting-json-to-rest-api/10324550#10324550) **I turned on log4j tracing on spring mvc and could see the parsing error. It was basically JSON input format was incorrect.** So did some trial and error and changed the crul request to make it work. **curl -v -H "Accept: application/json" -H "Content-type: application/json" -X POST -d {\"key\":\"XYZ\",\"uniqueId\":\"ABCD\"} http://localhost:8080/api/rest/connect/tick/view.json** – Pradeep Sep 20 '13 at 13:40
  • @Pradeep THIS!!!! {\"key\":\"XYZ\",\"uniqueId\":\"ABCD\"} Thank you! – ThinkingStiff Jun 14 '14 at 07:15
  • +1 @Pradeep for pointing out how to find the actual parse error log. In my case was not needed to set `TRACE` as per your reference. `DEBUG` on `org.springframework.web.servlet.mvc` was enough. – h7r Nov 16 '14 at 13:27
  • you could also use the `@ConrollerAdvice` annotation and override the messageUnreadalbe method and then decide what to do with the exception. – igreenfield Jun 16 '15 at 19:23
