spring-boot cors angular Java

I've encountered a strange issue with I'm integrating two systems and I am working with a CORS scenario while trying to connect my Angular front-end with a Spring Boot REST API... When I try to make a request from the Angular application, I receive a `403 Forbidden` behavior, and the console logs indicate that the request has been blocked due to CORS policy. I have already tried adding the `@CrossOrigin` annotation to my controller like this: ```java @RestController @CrossOrigin(origins = "http://localhost:4200") public class MyController { @GetMapping("/api/data") public ResponseEntity<List<MyData>> getData() { // Fetch data logic } } ``` Despite this, the scenario continues. I've also configured global CORS settings in my `WebMvcConfigurer`: ```java @Configuration public class WebConfig implements WebMvcConfigurer { @Override public void addCorsMappings(CorsRegistry registry) { registry.addMapping("/api/**").allowedOrigins("http://localhost:4200").allowedMethods("GET", "POST", "PUT", "DELETE"); } } ``` However, I still get the same behavior message when I try to call the API. I've verified that the Angular application is indeed running on port 4200, and the API is accessible directly through the browser (http://localhost:8080/api/data). Additionally, I have made sure to include the `HttpClientModule` in my Angular app as follows: ```typescript import { HttpClientModule } from '@angular/common/http'; @NgModule({ declarations: [...], imports: [HttpClientModule, ...], bootstrap: [AppComponent] }) export class AppModule {} ``` I've also checked the browser's developer tools to ensure that the OPTIONS preflight request is being sent and that it's being blocked. Could the scenario be related to the server's response headers? Is there something in the Spring Boot configuration that I might be missing? Any help or suggestions would be greatly appreciated! This is for a service running on Windows 11. This issue appeared after updating to Java 3.10. Any pointers in the right direction?
