Rest Controller中的删除方法错误问题

我的项目中有一些Rest端点，这些端点是从另一台服务器的客户端应用程序调用的。我已成功使用@CrossOrigin注释禁用了Cors

，除Delete方法在Chrome上引发以下错误外，所有方法均正常运行：

XMLHttpRequest cannot load

http://localhost:8856/robotpart/1291542214/compatibilities. Response to

preflight request doesn't pass access control check: No 'Access-Control-Allow-

Origin' header is present on the requested resource. Origin

'http://127.0.0.1:8888' is therefore not allowed access. The response had HTTP

status code 403.

这是我的控制器：

@CrossOrigin(origins = "*")
@ExposesResourceFor(RobotPart.class)
public class RobotPartController {
      //All endpoints are working except the Delete Mapping
    @GetMapping("/robotpart")
    public ResponseEntity<List<RobotPartResource>> listAllParts() {
        //..
    }
    @GetMapping("/robotpart/{id}")
    public ResponseEntity<RobotPartResource> getById(@PathVariable Integer id) {
        //..
    }
    @GetMapping("/robotpart/{id}/compatibilities")
    public ResponseEntity<Collection<RobotPartResource>> getRobotCompatibilities(@PathVariable Integer id,
          //..
    }
    @PostMapping("/robotpart")
    public ResponseEntity<RobotPartResource> getById(@RequestBody @Valid RobotPart newRobot) {
        //..
    @PutMapping("/robotpart/{id}")
    public ResponseEntity<RobotPartResource> modify(@PathVariable Integer id, @Valid @RequestBody RobotPart newRobot) {
         //...
    }
    @DeleteMapping("/robotpart/{id}")
    public ResponseEntity<RobotPart> deleteById(@PathVariable Integer id) {
        //...
    }
    }

可以解决吗？

回答：

在分析http请求之后，我找到了一个解决方案，我注意到Access-Control-Allow-

Methods标头缺少DELETE方法，因此我通过删除@CrossOrigin批注来添加它，并将此bean添加到配置中：

        @Bean
        public WebMvcConfigurer corsConfigurer() {
            return new WebMvcConfigurerAdapter() {
                @Override
                public void addCorsMappings(CorsRegistry registry) {
                    registry.addMapping("/robotpart/**").allowedOrigins("*").allowedMethods("GET", "POST","PUT", "DELETE");
                }
            };
        }
