Spring CORS

• Cross Origin Resource Sharing
• 도메인이 다를 때 설정

Code

Controller

• @CrossOrigin(origins = "http://localhost:8080")

@RequestMapping("/somePath")
@CrossOrigin(origins = "*", allowedHeaders = "*")
public class SomeController {}

@RestController
@RequestMapping("/somePath")
public class SomeController {

	@CrossOrigin(origins="*")
	@DeleteMapping(value = "/{key}",method = RequestMethod.DELETE)
	public Object delete(@PathVariable String key) {}

}

Global

• java
• properties
• YAML

  @Bean
  public WebMvcConfigurer corsConfigurer() {
    return new WebMvcConfigurer() {
      @Override
      public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/greeting-javaconfig").allowedOrigins("http://localhost:8080");
      }
    };
  }

@Configuration
public class WebConfig implements WebMvcConfigurer {
  @Override
  public void addCorsMappings(CorsRegistry registry) {
    registry.addMapping("/**")
      .allowedOrigins("http://localhost:8080", "http://localhost:8090")
			.maxAge(3000);
  }
}

• WebMvcConfigurer: 전역 설정
• .addCorsMapping(): CORS 설정 메소드
• .addMapping("/**"): 패턴
• .allowedOrigins(): 허용 도메인
• .allowedOrigins("*"): 모든 도메인 허용
• .maxAge(): preflight 캐시 시간
