Java Spring控制器拒绝所有期望GET的请求

Question

我正在Angular上使用前端开发Java Spring应用程序，但是我遇到的问题是没有您的帮助我无法解决。当我从Angular向Java发出请求时，只有GET请求正在传递，但POST，DELETE和POST返回以下错误

已从CORS策略阻止从原点[http://localhost:8080/patient'访问'http://localhost:4200处XMLHttpRequest：在所请求的资源上没有'Access-Control-Allow-Origin'标头。

控制者

@Controller
@RequestMapping("/patient")
@CrossOrigin(origins = "*", maxAge = 3600)
public class PatientController {

    private PatientService patientService;

    @Autowired
    public PatientController(PatientService patientService) {
        this.patientService = patientService;
    }

    @GetMapping
    public ResponseEntity<Iterable<Patient>> getPatient() {
        return new ResponseEntity<>(patientService.findAll(), HttpStatus.OK);
    }

    @PostMapping
    public ResponseEntity<Iterable<Patient>> postPatient() {
        return new ResponseEntity<>(patientService.findAll(), HttpStatus.OK);
    }

    @PutMapping
    public ResponseEntity<Iterable<Patient>> putPatient() {
        return new ResponseEntity<>(patientService.findAll(), HttpStatus.OK);
    }

    @DeleteMapping
    public ResponseEntity<Iterable<Patient>> deletePatient() {
        return new ResponseEntity<>(patientService.findAll(), HttpStatus.OK);
    }

}

Angular service

  getPatients() {
    this.http.post(AppComponent.apiUrl + '/patient', this.httpOptions) 
      .subscribe(data => {
        console.log(data);
      });
  }

proxy.conf.json

{ "/api*": {
    "target":"http://localhost:8080",
    "secure":false,
    "logLevel":"debug",
    "changeOrigin": true 
   }
}

谢谢你！

不需要在origins=*批注中设置@CrossOrigin，默认情况下允许所有原点。

您试图将注释置于方法级别？
