Spring 4 , REST Service returns a 415 error from Tomcat

Question

I am trying to test the POST method in a REST service with Spring 4. It works fine in my integration tests with MockMvcBuilders.standaloneSetup but I deployed it in a Tomcat 8.5.8 and I can no understand why it is not working. I receive this message:

                              HTTP Status 415 -

   type Status report

   message

   description The server refused this request because the request entity
   is in a format not supported by the requested resource for the
   requested method.
     ________________

but the Tomcat Server receives this request (extracted from wireshark):

POST /app-1.0-SNAPSHOT/v1.0/concentrators/ HTTP/1.1 
User-Agent: curl/7.35.0 
Host: x.x.x.x:8080 
Accept: */* 
Content-Type: application/json 
Content-Length: 528 {"street":"street","num":"num","code":"code","town":"town"
,"descriptionRoom":"descriptionRoom","btPwd":"btPwd"
,"gprsPwd":"gprsPwd","gprsLogin":"gprsLogin","gprsApn":"gprsApn"
,"gprsPin":"gprsPin","motherboardId":"motherboardId","logLevel":0
,"frameSendPeriod":0,"frameCapturePeriod":0,"mQTTServerPwd":"mQTTServerPwd"
,"mQTTServerUser":"mQTTServerUser","mQTTServerIp":"mQTTServerIp"
,"ftpServerPwd":"ftpServerPwd","ftpServerUser":"ftpServerUser"
, "ftpServerIp":"ftpServerIp","numSerie" :"numSerie","idConcentrator":-1,"infoCameras":[]}

It seems fine I don't know where is the mistake.

My REST service is:

@RequestMapping(value = "/", method = RequestMethod.POST, consumes = { "application/json" }, produces = { "application/json" })
public ResponseEntity<String> post(@RequestBody ConfigurationConcentrator configurationConcentrator) {
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_JSON);
    try {
        configureConcentrator.create(configurationConcentrator);
    } catch (IncorrectDBOperation | ErrorSendMessageException e) {
        return new ResponseEntity<String>(e.getMessage(), headers, HttpStatus.BAD_REQUEST);
    }
    return new ResponseEntity<String>(HttpStatus.CREATED);
}

Also, It checked the jackson dependencies (databind, core and annotations) and they are added in .war file. This is my curl command:

 curl -X POST -H "Content-Type: application/json" --data  @addConcentrator2.json http://x.x.x.x:8080/app-1.0-SNAPSHOT/v1.0/concentrators/

It seems, It can not resolve correctly which interceptor needs, but I don't see the problem:

    @RequestMapping(value = "/{id}", method = RequestMethod.GET, consumes = { "application/json" }, produces = { "application/json" })
    public @ResponseBody ResponseEntity<ConfigurationConcentrator> get(@PathVariable("id") String id) {
....
    }

    @RequestMapping(value = "/", method = RequestMethod.POST, consumes = { "application/json" }, produces = { "application/json" })
    public ResponseEntity<String> post(@RequestBody ConfigurationConcentrator configurationConcentrator) {
....

    }

    @RequestMapping(value = "/{id}", method = RequestMethod.PUT, consumes = { "application/json" }, produces = { "application/json" })
    public ResponseEntity<String> put(@PathVariable("id") String id, @RequestBody ConfigurationConcentrator configurationConcentrator) {
....

    }

    @RequestMapping(value = "/{id}/cameras/{idcamera}", method = RequestMethod.PUT, consumes = { "application/json" }, produces = { "application/json" })
    public ResponseEntity<String> putCameras(@PathVariable("id") String id, @PathVariable("idcamera") String idCamera,
....

    }

    @RequestMapping(value = "/{id}/cameras", method = RequestMethod.POST, consumes = { "application/json" }, produces = { "application/json" })
    public ResponseEntity<String> postCameras(@PathVariable("id") String id, @RequestBody List<ConfigurationCamera> configurationCameras) {
....
    }

    @RequestMapping(value = "/{id}/initialconfiguration", method = RequestMethod.GET, consumes = { "application/json" }, produces = { "application/json" })
    public ResponseEntity<StatusInitialConfiguration> getInitialConfiguration(@PathVariable("id") String numSerie) {
....


    }

UPDATE1: I updated the curl command with the Accept header.

curl -X POST -H "Content-Type: application/json" -H "Accept: application/json" --data  @addConcentrator2.json http://x.x.x.x:8080/app-1.0-SNAPSHOT/v1.0/concentrators/

UPDATE2: I think, It is detecting two interceptors:

    public void setStatus(String status) {
        this.status = status;
    }

}

UPDATE4

I simplified the mapped object class , and I receive the same error.

public class DTOConfigurationConcentrator {
    private String street;
    private String num;

    public DTOConfigurationConcentrator() {
        super();
    }

    public String getStreet() {
        return street;
    }

    public void setStreet(String street) {
        this.street = street;
    }

    public String getNum() {
        return num;
    }

    public void setNum(String num) {
        this.num = num;
    }

}

It seems something related to the tool for the json serialization but I don't know exactly how I can check this.

Answer 1

I forgot to tag my configuration class with @EnableWebMvc...
