Nifi disabled controller service rest api call failed

I use spring 4.2.0and nifi 0.6.0when I use RestTemplate to call restful api for disabled nifi controllers

//get nifi revision
public RevisionDTO getRevision() {
    Entity revision = restTemplate.getForObject("http://localhost:8083/nifi-api//controller/revision", Entity.class);
    return revision.getRevision();
}

//http parameter
protected Map<String, Object> getRevisionUrl(RevisionDTO revision) {
    Map<String, Object> urlVar = new HashMap<String, Object>();
    urlVar.put("version", revision.getVersion());
    urlVar.put("clientId", revision.getClientId());
    return urlVar;
}

//disable controller service
private void disable(ControllerServiceEntity cs) {
    Map<String, Object> urlVar = getRevisionUrl(getRevision());
    urlVar.put("state", STATE_DISABLED);
    restTemplate.put("http://localhost:8083/nifi-api/controller/controller-services/node/" + cs.getControllerService().getId(), null, urlVar);
}

I got the following error log:

org.springframework.web.client.HttpClientErrorException: 409 Conflict

Is there any way to fix the error?

@Matt Gilman I changed the function in disabletwo ways:

private void disable(ControllerServiceEntity cs) {
    //http form
    /*MultiValueMap<String, String> urlVar = getRevisionUrl(getRevision());
    urlVar.add("state", STATE_DISABLED);

    HttpHeaders requestHeaders = new HttpHeaders();
    requestHeaders.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
    HttpEntity<MultiValueMap<String, String>> requestEntity = new HttpEntity<MultiValueMap<String, String>>(urlVar, requestHeaders);*/

    //http json
    ControllerServiceEntity csu = new ControllerServiceEntity();
    csu.setRevision(getRevision());
    csu.setControllerService(cs.getControllerService());
    csu.getControllerService().setState(STATE_DISABLED);
    HttpHeaders requestHeaders = new HttpHeaders();
    requestHeaders.setContentType(MediaType.APPLICATION_JSON);
    HttpEntity<String> requestEntity = new HttpEntity<String>(JSONUtils.obj2json(csu), requestHeaders);

    restTemplate.put(url() + cs.getControllerService().getId(), requestEntity);
}

but i got the same error in nifi:

java.lang.IllegalStateException: DBCPConnectionPool[id=fecc88a8-379d-4fb3-b880-28c5f5caef23] cannot be updated because it is not disabled

resolved

i compare the request to turn off the browser and run the api doc again, found to disable the controller service should do the following:

  • link to stop service
  • disable management service link
  • set service manager service status

now my new shutdown function

private void disable(ControllerServiceEntity cs) {
    //http form
    HttpHeaders requestHeaders = new HttpHeaders();
    requestHeaders.setContentType(MediaType.APPLICATION_FORM_URLENCODED);

    //stop controller service reference
    MultiValueMap<String, String> urlVar = getRevisionUrl(getRevision());
    urlVar.add("state", STATE_STOPPED);
    HttpEntity<MultiValueMap<String, String>> requestEntity = new HttpEntity<MultiValueMap<String, String>>(urlVar, requestHeaders);
    restTemplate.put(url() + cs.getControllerService().getId() + "/references", requestEntity);

    //disable controller service reference
    urlVar = getRevisionUrl(getRevision());
    requestEntity = new HttpEntity<MultiValueMap<String, String>>(urlVar, requestHeaders);
    urlVar.add("state", STATE_DISABLED);
    restTemplate.put(url() + cs.getControllerService().getId() + "/references", requestEntity);

    //set controller service disable state
    urlVar = getRevisionUrl(getRevision());
    requestEntity = new HttpEntity<MultiValueMap<String, String>>(urlVar, requestHeaders);
    urlVar.add("state", STATE_DISABLED);
    restTemplate.put(url() + cs.getControllerService().getId(), requestEntity);
}
