How to handle large JSON payloads in a Spring Boot web service without hitting timeout?
I've encountered a strange issue with I've hit a wall trying to I'm currently developing a Spring Boot web service that processes large JSON payloads, and I've been running into a timeout issue when clients send requests that exceed 2MB. Despite increasing the `server.servlet.multipart.max-file-size` and `server.servlet.multipart.max-request-size` settings in my `application.properties` file to 10MB, I still receive a `org.springframework.web.multipart.MaxUploadSizeExceededException`. Here's how I configured my `application.properties`: ```properties server.servlet.multipart.max-file-size=10MB server.servlet.multipart.max-request-size=10MB ``` On the client side, I'm using a simple JavaScript function to send a POST request: ```javascript fetch('http://localhost:8080/api/upload', { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify(largeJsonData) // largeJsonData is quite substantial }); ``` When I send the request, the server logs show a timeout occurring after about 30 seconds, which isn't enough time for the large payload. I've tried increasing the timeout in the controller with the following annotation: ```java @CrossOrigin @RestController @RequestMapping("/api") public class UploadController { @PostMapping("/upload") public ResponseEntity<String> uploadData(@RequestBody YourDataType data) { // Process the data return ResponseEntity.ok("Data processed successfully"); } } ``` Additionally, I tried setting the timeout in the `@RequestMapping` like so: ```java @RequestMapping(value = "/upload", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE, consumes = MediaType.APPLICATION_JSON_VALUE) ``` Despite these attempts, I still run into the same issues. Is there a specific configuration I might be missing, or a better approach to handle large payloads in a Spring Boot application? Any insights on how to optimize this would be greatly appreciated! Cheers for any assistance!
