Question

我正在尝试使听者中的corsOrgin能够使用Ajax从laravel应用程序中使用剩余api。但是，在客户端控制器中编写@CrossOrigin（origins =“ http://localhost:8080”）之后，它向我显示警告CrossOrigin无法解析为类型。有人知道如何解决此问题吗？

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

Client.Controller

$("#a1").on("click", "a", function() { 
    var lang = $(this).data("lang");
    window.location = "http://flysmarter."+lang;
  });

pom.xml

@CrossOrigin(origins = "http://localhost:8080")
    @RequestMapping(value = "/clients", method = RequestMethod.GET)
    @Produces({ MediaType.APPLICATION_JSON })
    public ResponseEntity<?> getAllClients() {

        List<Client> clients = clientService.loadAll();

        return new ResponseEntity<>(clients, HttpStatus.OK);
    }

只需在服务器端设置响应标头，例如res.setHeader("Access-Control-Allow-Origin", "*");。

//@CrossOrigin(origins = "http://localhost:8080")
@RequestMapping(value="getDeatils", method=RequestMethod.GET,   produces="application/json" )
public ResponseEntity<JSONObject> getTinDetails(HttpServletRequest req, @RequestParam("gstin") String gstin, HttpServletResponse res) { 

 res.setHeader("Access-Control-Allow-Origin", "*");

           return new ResponseEntity<JSONObject>(responceObj, HttpStatus.OK);
        }else{

                throw new UserException("_GSTC_INVALID_GSTIN_");


        }

}

只需尝试一下，它就对我有用。如果有助促进
