  }
这是迄今为止该微服务中的唯一控制器，我已经尝试了@CrossOrigin（origins =“ ”，allowedHeaders =“

@RestController
@RequestMapping(path="/api/v1")
@AllArgsConstructor
public class SomeRestController {

    @Bean
    public WebMvcConfigurer corsConfigurer() {
        return new WebMvcConfigurerAdapter() {
            @Override
            public void addCorsMappings(CorsRegistry registry) {
                registry.addMapping("/**").allowedOrigins("*");
            }
        };
    }

    @Autowired
    private SomeService someService;


    @PostMapping(path="/foo/bar")
    public ResponseEntity<RespObject> dosomething(@Valid @RequestBody RequestDTO requestDTO) 
    .
            .
            .
    //somecode
}
