I have two methods in controller, this is handler request from client. I can't get request body of PUT. For send request i use Advanced Rest Client in Chrome.
#RequestMapping(value = "/addPupil", method = RequestMethod.POST)
public void addPupil(Pupil pupil){
System.out.println(pupil.toString());
}
Result in Advanced Rest Client:
Status 200 OK Response does not contain any data.
stdout:
Pupil{address='is address', level='is level', group='is group', last='is last', name='is name'}
But problem with this method, i can't get pupil object!
#RequestMapping(value = "/changePupil/{id}", method = RequestMethod.PUT)
public void changePupil(#PathVariable("id") Long id, Pupil pupil){
System.out.println("id: "+id);
System.out.println(pupil.toString());
}
Result in Advanced Rest Client:
Status 200 OK Response does not contain any data.
stdout:
id: 2
Pupil{address='null', level='null', group='null', last='null', name='null'}
you should use #RequestBody
#RequestMapping(value = "/changePupil/{id}", method = RequestMethod.PUT)
public void changePupil(#PathVariable("id") Long id,#RequestBody Pupil pupil){
System.out.println("id: "+id);
System.out.println(pupil.toString());
}
Take an advantage of #RestController on your controller class instead of #Controller and specify the MediaType that your rest method consuming and you may have to register appropriate HttpMessageConverter too.

I have a Spring MVC Controller and a PUT mapping that consumes JSON. I receive the JSON and everything just fine, the problem is whenever I fire off the JSON the mapper wants to redirect to the URL, giving me error 500 because the server can't find any template for the URL. How can I stop Spring MVC from trying to redirect to the URL and just receive the JSON?
My relevant Controller code :
#RequestMapping(value = "admin/users/VMs", method = RequestMethod.PUT, consumes = "application/json")
public void removeVM(#RequestBody ManageVMRequest packet, Authentication authentication) {
System.out.println(packet.getVm());
System.out.println(packet.getUser_id());
}
You can try to return ResponseEntity<Void>
#RequestMapping(value = "admin/users/VMs", method = RequestMethod.PUT, consumes = "application/json")
public #ResponseBody ResponseEntity<Void> removeVM(#RequestBody ManageVMRequest packet, Authentication authentication) {
System.out.println(packet.getVm());
System.out.println(packet.getUser_id());
return new ResponseEntity<Void>(HttpStatus.NO_CONTENT);
}
I have a REST controller that defines an interface which takes an optional request body.
#RestController
#RequestMapping(ExampleRest.EXAMPLE_URI)
public class ExampleRest {
public static final String EXAMPLE_URI = "/examples";
#RequestMapping(value = "/search", method = POST)
public Page<ExampleDto> search(#RequestBody(required = false) Searchable searchable, Pageable pageable) {
return exampleService.findAll(searchable, pageable);
}
}
The Searchable object contains information to create a JPASpecification. It's pretty much a dto. I would like to make this searchable optional. I understood that #RequestBody(required = false) should do the trick.
I have the following test, where I want to test a request without any request body.
#Test
public void post_NoCriteria_Ok() {
RequestEntity requestEntity = new RequestEntity(HttpMethod.POST, URI.create(ExampleRest.EXAMPLE_URI + "/search"));
ResponseEntity <RestResponsePage<ExampleDto>> response = restTemplate.exchange(requestEntity, new ParameterizedTypeReference <RestResponsePage<ExampleDto>> () {});
Assert.assertEquals(HttpStatus.OK, response.getStatusCode());
}
If I run this test, it keeps failing with this response from the RestController:
<415 Unsupported Media Type,Page 1 of 1 containing UNKNOWN
instances,{Content-Type=[application/json;charset=UTF-8],
Transfer-Encoding=[chunked], Date=[Wed, 13 Sep 2017 10:10:22 GMT]}>
The Code execution does not even enter search method implementation inside of the RestController.
As soon I provide an empty Searchable for the test, it runs through.
Is the implementation of #RequestBody(required = false) buggy, or what am I doing wrong here?
You need to set Content-Type as "application/json" in your request while sending from #Test file.
I need a rest end point whose response is HTML. But instead of a view defined in my project, i would like to forward the HTML response from another request made inside that rest end point.
For example, my rest end point makes a http request to an internal service and returns the HTML returned from that service? Is it possible? Any thoughts?
Here is a code example
#RequestMapping("/test")
public String testMe(Model model, #RequestParam("param1") String param1, #RequestParam("param2") String param2)
{
//Make a Http call to an internal service and return the response from that call
return "<RESPONSE_FROM_THAT_CALL>";
}
I would like to return the HTML response from the internal service
You can use a RestTemplate to fetch the result from the other service and just return it as a String:
#Controller
public class MyController {
private RestTemplate restTemplate = new RestTemplate();
#ResponseBody
#RequestMapping("/test")
public String testMe(Model model, #RequestParam("param1") String param1, #RequestParam("param2") String param2) {
URI uri = UriComponentsBuilder.fromHttpUrl("http://www.example.com");
.queryParam("param1", param1)
.queryParam("param2", param2)
.build()
.toUri());
return restTemplate.getForObject(uri, String.class);
}
}
If you'll have more endpoints that you wanna proxy to another service, you should consider using e.g. Zuul as a micro proxy. See e.g. this blog post explaining how you can easily create such a proxy.
I load at browser as
localhost:8080/picking/addPick get error HTTP Status 405 - Request method 'GET' not supported.
What wrong?Hope advice thanks
#Controller
#RequestMapping("/picking")
public class PickerController {
#RequestMapping(method = RequestMethod.GET)
public #ResponseBody ArrayList getAllPickingItems()throws SQLException, ClassNotFoundException{
//....
}
#RequestMapping(value="/addPick",method=RequestMethod.POST)
#ResponseStatus(HttpStatus.CREATED)
public Boolean add(#RequestBody PickingInfo pickingInfo,HttpServletResponse response){
try{
Boolean success = pickerMethod.addPickingInfo(pickingInfo);
response.setHeader("addPickingInfo", success+"");
return true;
}catch(Exception ex){
System.out.println(ex.getMessage());
}
return false;
}
}
You limited URI/picking/addPick to POST requests :
#RequestMapping(value="/addPick",method=RequestMethod.POST)
When you try to open that URI from your browser you're sending a GET request, not a POST. If you want to be able to access /picking/addPick from your browser you must either :
remove the restriction method=RequestMethod.POST
allow explicitely GET requests : method = { RequestMethod.POST, RequestMethod.GET }
If you just want to test a POST method, use SoapUI. Simply create a "New REST Project", paste your service URI, and send any type of HTTP Request you want.
You have mapped /addPick to the add method only for POST requests. Therefor GET is not mapped to anything (and in this case there is no point in mapping get to the method since you are also using #RequestBody)
I'm trying to forward a request from one controller to another controller and set a object in request so that the forwarded controller can use it in #RequestBody.
Following is the exact scenario:
Twilio calls a controller method with data sent by client as following:
#RequestMapping(value = "/sms", method = RequestMethod.POST)
public String receiveSms(#RequestParam("Twiml") String twiml,
HttpServletRequest request,
HttpServletResponse response) {
//TODO - Create new instance of Activity and populate it with data sent from client
return "forward:/activity/new";
}
Now, I want to forward this request to ActivityController which already handles the request from web/rest clients.
ActivityController.java has a method with following signature:
#RequestMapping(value = "/activity/new", method = RequestMethod.POST)
public ResponseEntity<Activity> updateLocation(
#RequestBody Activity activity) {
}
Is it possible? If yes, how?
Thanks,
Create the object and add it to the request as an attribute in the first controller,
request.setAttribute("object",new OwnObject()),
return "forward:/activity/new";
In the updateLocation Method retrieve that object from the request
#RequestMapping(value = "/activity/new", method = RequestMethod.POST)
public ResponseEntity<Activity> updateLocation(
#RequestBody Activity activity, HttpServletRequest request) {
OwnObject o = (OwnObject) request.getAttribute("object");
}
