spring-restcontroller

I'm writing a Rest Service (HTTP Get endpoint), where in the below uri does the following http://localhost:8080/customers/{customer_id} fetch the details for the customer_id passed in the uri if the customer_id is not passed ( http://localhost:8080/customers ), fetch all the customers details. Code: @RequestMapping(method = RequestMethod.GET, value = "customers/{customer_id}") public List<Customer> getCustomers( @PathVariable(name = "customer_id", required = false) final String customerId) { LOGGER.debug("customer_id {} received for getCustomers request", customerId); } However, with the above

I have POST method in a Spring boot rest controller as follows @RequestMapping(value="/post/action/bookmark", method=RequestMethod.POST) public @ResponseBody Map<String, String> bookmarkPost( @RequestParam(value="actionType",required=true) String actionType, @RequestParam(value="postId",required=true) String postId, @CurrentUser User user) throws Exception{ return service.bookmarkPost(postId, actionType, user); } now if I test with missing parameter in Postman I get an 400 http response and a JSON body: { "timestamp": "2015-07-20", "status": 400, "error": "Bad Request", "exception": "org

I have this endpoint for Spring Rest API: @PostMapping(value = "/v1/", consumes = { MediaType.APPLICATION_XML_VALUE, MediaType.APPLICATION_JSON_VALUE }, produces = { MediaType.APPLICATION_XML_VALUE, MediaType.APPLICATION_JSON_VALUE }) public PaymentResponse handleMessage(@RequestBody PaymentTransaction transaction, HttpServletRequest request) throws Exception { // get here plain XML } XML model. @XmlRootElement(name = "payment_transaction") @XmlAccessorType(XmlAccessType.FIELD) public class PaymentTransaction { public enum Response { failed_response, successful_response } @XmlElement(name =

I want to return a simple plain text string as follows: @RestController @RequestMapping("/test") public class TestController { @ResponseStatus(HttpStatus.OK) @RequestMapping(value = "/my", method = RequestMethod.GET, produces="text/plain") public String test() { return "OK"; } Problem: I also have a global ContentNegotiation filter as follows: @Configuration public class ContentNegotiationAdapter extends WebMvcConfigurerAdapter { @Override public void configureContentNegotiation(ContentNegotiationConfigurer configurer) { configurer.favorPathExtension(false) .favorParameter(true)

I have a data class, something like this: public class Person { private String name; private Long code; // corresponding getters and setters } I want to write two web services that provide two different JSON representation of Person. For example, one of them provide {"name":"foo"} but the other one {"name":"foo", "code":"123"} . As a more complicated scenario, suppose that Person has a reference property, for example address. Address has its own properties as well and I expect that both of my web services consider this property but each of which do this in their own manner. How should my

What is the difference between below two and which on to Use when ? @GetMapping(path = "/usr/{userId}") public String findDBUserGetMapping(@PathVariable("userId") String userId) { return "Test User"; } @RequestMapping(value = "/usr/{userId}", method = RequestMethod.GET) public String findDBUserReqMapping(@PathVariable("userId") String userId) { return "Test User"; } As mentioned in the comments (and the documentation ), value is an alias to path . Spring often declares the value element as an alias to a commonly used element. In the case of @RequestMapping (and @GetMapping , ...) this is the

Using spring boot, I want to make RESTful-based video player. I have my .mp4 extension videos in my file browser. How can I serve these videos on the frontend side by creating a rest endpoint? I've tried this method. The video can be started or stopped. But it can not be done backwards or forwards. Can not get it to the desired minute and start. Spring Content supports video streaming out of the box. Using Spring Content for the file-system (FS) you would be able to create yourself a video store backed by the filesystem, put your video(s) in that store, and using the companion library Spring

This returns 200 OK with Content-Length: 0 @RestController public class RepoController { @RequestMapping(value = "/document/{id}", method = RequestMethod.GET) public Object getDocument(@PathVariable long id) { return null; } } Simply put I'd like it to return 204 No Content on null. Is there a way to force spring-mvc/rest to return 204 on null not 200? I dont want to change every rest method to return ResponseEntity or something like that, only map null to 204 Karthik R Of course yes. Option 1 : @RestController public class RepoController { @RequestMapping(value = "/document/{id}", method =
