Spring MVC: guide with CORS Configuration on Nested Resource Endpoints
I'm working through a tutorial and I'm trying to configure I'm working with a CORS scenario in my Spring MVC application when trying to access nested resource endpoints. I've set up a configuration class to handle CORS, but it seems to only apply to the top-level endpoints and not to the nested resources. For instance, I can access `GET /api/products` without any issues, but when I try to access `GET /api/products/1/reviews` from a different origin, I'm getting a `CORS policy behavior: No 'Access-Control-Allow-Origin' header is present on the requested resource.` I've tried explicitly specifying the allowed origins in my CORS configuration like this: ```java import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.web.servlet.config.annotation.CorsRegistry; import org.springframework.web.servlet.config.annotation.WebMvcConfigurer; @Configuration public class WebConfig implements WebMvcConfigurer { @Override public void addCorsMappings(CorsRegistry registry) { registry.addMapping("/api/**").allowedOrigins("http://example.com"); } } ``` Despite this, the CORS policy behavior still continues for the nested resource. I've also tried adding more specific mappings like `registry.addMapping("/api/products/**").allowedOrigins("http://example.com");`, but it still doesn't resolve the scenario. Additionally, I verified that the Spring Boot version I'm using is 2.5.4 and I've included the following dependency in my Maven `pom.xml`, which should handle CORS configuration: ```xml <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> ``` I have also checked that my front-end code correctly sends the requests with the appropriate headers. What am I missing here? Is there a specific way to handle CORS for nested endpoints in Spring MVC? Any insights or solutions would be greatly appreciated! For reference, this is a production desktop app. This is for a microservice running on Windows 11. I appreciate any insights! I'm open to any suggestions.
