I have a below controller
#Controller
public class TestController{
public Future<ArrayList<String>> global_value = null;
#Autowired
private AsyncService asyncService;
#RequestMapping(value = "/asyncCall", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)
#ResponseBody
public String getToken(HttpServletRequest request) {
global_value = asyncService.execute();
return "OK";
}
#RequestMapping(value = "/getAsyncData", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)
#ResponseBody
public ArrayList<String> getData() {
try {
if (global_value != null && global_value.get().size() > 0) {
return global_value.get();
}
} catch (InterruptedException e) {
e.printStackTrace();
} catch (ExecutionException e) {
e.printStackTrace();
}
return null;
}
}
When I long poll the getAsncData endpoint, how do I maintain the global_value is just for a request. global_value must be unique for the request scope.
How can I achieve this?

I want to return JSON below.
{
"name": "jackie"
}
Postman is giving me error. Stating
Unexpected 'n'
New to Spring Boot here. 1 day old. Is there a proper way to do this?
// POST method here
#RequestMapping(method = RequestMethod.POST , produces = "application/json")
ResponseEntity<?> addTopic(#RequestBody Topic topic) {
if (Util.save(topicRepository, new Topic(topic.getTopicName(), topic.getQuestionCount())) != null) {
return Util.createResponseEntity("Name : jackie", HttpStatus.CREATED);
}
return Util.createResponseEntity("Error creating resource", HttpStatus.BAD_REQUEST);
}
This is what I use:
#GetMapping(produces = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<Map<String, String>> hello() {
try {
Map<String, String> body = new HashMap<>();
body.put("message", "Hello world");
return new ResponseEntity<>(body, HttpStatus.OK);
} catch (Exception e) {
return new ResponseEntity<>(HttpStatus.INTERNAL_SERVER_ERROR);
}
}
Create model and store value in that model and return model from controller.
Check Below code.
class User{
private String name;
//getter and setter
}
#RequestMapping(method = RequestMethod.POST , produces = "application/json")
ResponseEntity<User> addTopic(#RequestBody Topic topic) {
User user=new User();
user.setName("myname");
HttpHeaders httpHeaders = new HttpHeaders();
return new ResponseEntity<User>(user, httpHeaders, HttpStatus.CREATED);
}
Try wrapping your response in object.
class Response implements Serializable {
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
And Controller can be like this:
#RequestMapping(method = RequestMethod.POST , produces = "application/json")
ResponseEntity<?> addTopic(#RequestBody Topic topic) {
if (Util.save(topicRepository, new Topic(topic.getTopicName(), topic.getQuestionCount())) != null) {
Response response = new Response();
response.setName("jackie");
return new ResponseEntity<>(response, HttpStatus.CREATED);
}
return Util.createResponseEntity("Error creating resource", HttpStatus.BAD_REQUEST);
}
#PostMapping("/register/service/provider")
public ResponseEntity<?> registerServiceProvider(#RequestBody ServiceProviderRequestPayload providerContext) {
try {
if (providerContext == null)
throw new BadRequestException("the request body can not be null or empty.");
if (!providerContext.isValid())
throw new BadRequestException("The request body doesn't seems to be valid");
return ResponseEntity.ok().contentType(MediaType.APPLICATION_JSON).body(new ObjectMapper().writeValueAsString(providerContext));
} catch (BadRequestException | IllegalArgumentException e) {
return ResponseEntity.badRequest().header("message", e.getMessage())
.contentType(MediaType.APPLICATION_JSON).build();
} catch (DuplicateKeyException keyException) {
return ResponseEntity.badRequest().header("message", "There seems to be farmer config" + keyException.getCause())
.contentType(MediaType.APPLICATION_JSON).build();
} catch (JsonProcessingException e) {
throw new RuntimeException(e);
}
}
Getting following exception while hitting a Rest endpoint. How do I typecast from String to ProtectPanReplyType class?
Error:

public class ProtectPanReplyType {

Use ResponseEntity<ProtectPanReplyType> instead ResponseEntity<String>
Build and Return ProtectPanReplyType from your restOperations.postForEntity()
Was finally able to get the object after making following changes.

public ResponseEntity<?> callClientByEndpointandMessage(String xmlRequest, String endpoint, Class<?> replyType) throws JiBXException {

I would like to check if session not equals to null,then some button or link will be hidden.Or any other better way to do that?
This is my controller :
#RequestMapping(value = "/signin", method = RequestMethod.GET)
public Object signIn(HttpSession session) {
MemberSignIn signIn = new MemberSignIn();
signIn.setLoginId((String) session.getAttribute("loginId"));
return new ModelAndView("member/signin").addObject("signIn", signIn);
}
#RequestMapping(value = "/signin", method = RequestMethod.POST)
public Object signIn(#ModelAttribute MemberSignIn memberSignIn, HttpSession session, RedirectAttributes redirectAttributes) {
try {
Session s = memberService.signIn(memberSignIn);
session.setAttribute("loginId", memberSignIn.getLoginId());
session.setAttribute("token", s.getToken());
session.setAttribute("memberId", s.getMemberId());
MemberDetail detail = memberService.detail(s.getMemberId());
session.setAttribute("name", detail.getName());
return "redirect:/index";
} catch (Exception e) {
LOGGER.error(e.getMessage(), e);
return new ModelAndView("member/signin")
.addObject("signIn", memberSignIn)
.addObject("error", e.getMessage());
}
}
