My method is this:
#RequestMapping(value = "/asignar", method = RequestMethod.GET, headers = "Accept=application/json")
public #ResponseBody
ResponseViewEntity<ResultadoJSON> asignar(
#RequestParam(required = true, value = "usuario") String usuario,
#RequestParam(required = true, value = "clienteId") Long clienteId,
ListaLotes lotes) {
....
}
Object ListaLotes
public class ListaLotes {
private List<LoteForm> lotes;
}
Object LoteForm
public class LoteForm {
private Long loteId;
private Long cantidad;
}
But when i realize the petition throught PostMan, the object "lotes" its always null
PETITION REST
Rest Header
Rest body
What I should do for it works ? I can't modify my Java code its part of an API. Only can modify de REST Petition
As has already been commented, if you want to transfer data to your controller, you need to use the POST method and mark the paramter as #RequestBody.
// or #PostMapping
#RequestMapping(value = "/asignar", method = RequestMethod.POST, headers = "Accept=application/json")
public #ResponseBody
ResponseViewEntity<ResultadoJSON> asignar(
#RequestParam(required = true, value = "usuario") String usuario,
#RequestParam(required = true, value = "clienteId") Long clienteId,
#RequestBody ListaLotes lotes) {
....
}

I have this controller:
#RestController("ThresholdAdapter")
#RequiredArgsConstructor
#Component
public class ThresholdAdapter {
#Autowired
ThresholdQuery thresholdQuery;
#RequestMapping(value = "/jbdj", method = RequestMethod.GET)
public String testaux() {
return "lkajdfladjlksj";
}
#RequestMapping(value = "/threshold/list", method = RequestMethod.GET)
public List<Threshold> listThreshold(#RequestParam(required = false) String categoria, #RequestParam(required = false) String kpi, #RequestParam(required = false) String data, #RequestParam(required = false) String hora) {
return thresholdQuery.listThreshold(categoria, kpi, data, hora);
}
#RequestMapping(value = "/threshold/update", method = RequestMethod.GET)
public Threshold updateThreshold(#RequestParam String kpi, #RequestParam String weekday, #RequestParam String hour, #RequestParam String valor, #RequestParam Boolean status) {
return thresholdQuery.updateThreshold(kpi,weekday,hour,valor,status);
}
}
When I call:
http://localhost:8080/jbdj
It doesn´t work.
It show the 404 Not Found error.
You need to have the annotation for rest controller for your endpoint. Spring create a bean named as "thresholdAdapter". You should not give any name in "RestController" annotation.
#RestController
#RequiredArgsConstructor
#Component("thresholdAdapter")
There was setting for context path.
Thanks a lot.
I´m trying to make a request with or without parameters, according the code below:
#RequestMapping(value = "/threshold/list", method = RequestMethod.GET)
public List<Threshold> listThreshold(#RequestParam(required = false) String categoria, #RequestParam(required = false) String kpi, #RequestParam(required = false) String data, #RequestParam(required = false) String hora) {
return thresholdQuery.listThreshold(categoria, kpi, data, hora);
}
But when I call the endpoint this way:
http://localhost:8081/threshold/list?categoria=casa
I got the error below:
Not enough variable values available to expand 'categoria=casa'
I believe it should be 'name' instead of 'value'
#RequestParam(name="categoria",required = false)
I need to send a value from an Angularjs front to a springboot Java back-office.
The back is called by many other fronts and services.
Which means I can change The front but I have to make sure that any change on the back must not break it for the other callers.
So Extra headers or Other fields in the request body etc... any change that won't break the other existing calls is what I'm looking for.
An example of some methods signature:
A HTTP GET signature
#Override
#ResponseStatus(code = HttpStatus.OK)
#RequestMapping(value = "/", method = RequestMethod.GET)
public ResponseEntity<List<Something>> getSomething(
#RequestHeader(name = Constants.HEADER.SOME_CODE) final String code,
#RequestHeader(name = Constants.HEADER.COMPANY_ID) final String companyId,
#RequestHeader(name = Constants.HEADER.CLIENT_ID) final String clientId) {
A HTTP POST signature
#Override
#ResponseStatus(code = HttpStatus.OK)
#RequestMapping(value = "/{pathValue}/transactions", method = RequestMethod.POST)
public ResponseEntity<SomeResponse> requestSomething(
#RequestHeader(name = Constants.HEADER.EFS_CODE) final String vode,
#RequestHeader(name = Constants.HEADER.COMPANY_ID) final String companyId,
#RequestHeader(name = "Access-Code", required = false) final String codeAcces,
#RequestHeader(name = Constants.HEADER.CLIENT_ID) final String clientId,
#PathVariable("pathValue") final String pathValue,
#RequestBody #Valid Transact transaction) {
I'm new in Spring Boot and I want to have the same Request Mapping method for JSON and simple request params, for example:
#RequestMapping(value = "/start")
public String startPostProcess(#RequestParam(value = "url",
required = false,
defaultValue = "https://goo.gl") String url,
#RequestParam(value = "word",
required = false,
defaultValue = "Search") String word,
#RequestBody String hereGoesJSON) {
//Do some stuff
}
So, when request goes with params, only #RequestParam will work, in other cases we will use #RequestBody annotation.
localhost:8080/start?url=htts://google.com&word=Luck
Or may bee I'll be able to write method like this, for accepting any params:
#RequestMapping(value = "/start")
public String startPostProcess(#RequestBody String anyParam) {
//Parse this anyParam
}
?
I've not found this trick in spring documentation, so I will appreciate any links to it.
Okay, I've solved the problem :D
All that I just needed was 2 methods with the same mapping and explicitly specify RequestMethod type:
#RequestMapping(value = "/start")
public String startPostProcess(#RequestParam(value = "url",
required = false,
defaultValue = "https://goo.gl") String url,
#RequestParam(value = "word",
required = false,
defaultValue = "Search") String word) throws InterruptedException {
//Do some stuff
}
#RequestMapping(value = "/start", method = RequestMethod.POST, consumes = "application/json")
public String startJsonProcess(#RequestBody String body) {
//Do another stuff with RequestBody
}
UPD: added "consumes = "application/json". It helps dividing simple POST requests and JSON POST requests.
The normal uri which triggers the default controller to get all cars is just "/cars"
I want to be able to search for cars aswell with an uri, for example: "/cars?model=xyz" which would return a list of matching cars. All the request parameters should be optional.
The problem is that even with the querystring the default controller triggers anyway and I always get "all cars: ..."
Is there a way to do this with Spring without a separate search uri (like "/cars/search?..")?
code:
#Controller
#RequestMapping("/cars")
public class CarController {
#Autowired
private CarDao carDao;
#RequestMapping(method = RequestMethod.GET, value = "?")
public final #ResponseBody String find(
#RequestParam(value = "reg", required = false) String reg,
#RequestParam(value = "model", required = false) String model
)
{
Car searchForCar = new Car();
searchForCar.setModel(model);
searchForCar.setReg(reg);
return "found: " + carDao.findCar(searchForCar).toString();
}
#RequestMapping(method = RequestMethod.GET)
public final #ResponseBody String getAll() {
return "all cars: " + carDao.getAllCars().toString();
}
}
You can use
#RequestMapping(method = RequestMethod.GET, params = {/* string array of params required */})
public final #ResponseBody String find(#RequestParam(value = "reg") String reg, #RequestParam(value = "model") String model)
// logic
}
ie, the #RequestMapping annotation has a property called params. If all of the parameters that you specify are contained in your request (and all other RequestMapping requirements match), then that method will be called.
Try a variation of this:
#Controller
#RequestMapping("/cars")
public clas CarController
{
#RequestMapping(method = RequestMethod.get)
public final #ResponseBody String carsHandler(
final WebRequest webRequest)
{
String parameter = webRequest.getParameter("blammy");
if (parameter == null)
{
return getAll();
}
else
{
return findCar(webRequest);
}
}
}
