Spring MVC 和 AngularJS @RequestMapping

Question

我已经使用 Spring-boot 和 AngularJS 以及 REST 端点应用程序构建了一个应用程序。我制作的 Spring 控制器中的 @RequesMapping 有点卡住了。问题是，我有例子 url:

"localhost:8080/foo/bar/api/cardGenerated/0102".

'01'是第一个参数，'02'是第二个参数。我怎样才能映射到 @RequestMapping Spring 控制器以获得上面的 url。

这是我的控制器：

@RestController
@RequestMapping("/api")
public class CardGeneratedResource {
@RequestMapping(value = "/cardGenerated/{branchCode}{cardType}",
            method = RequestMethod.GET,
            produces = MediaType.APPLICATION_JSON_VALUE)
    @Timed
    public ResponseEntity<CardGenerated> get(@PathVariable("branchCode") String branchCode,
                                             @PathVariable("cardType") String cardType,
                                             HttpServletResponse response) {

        log.debug("REST request to get CardGenerated : " + branchCode + " and " + cardType);

        CardGenerated cardGenerated = cardGeneratedRepository.
                findTopByBranchCodeAndCardTypeOrderByCardNumberDesc(branchCode, cardType);

        if (cardGenerated == null) {
            return new ResponseEntity<>(HttpStatus.NOT_FOUND);
        }

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

所以这是我的 AngularJS $resource:

'use strict';

angular.module('itmApp')
    .factory('CardGenerated', function ($resource) {
        return $resource('api/cardGenerated/:branchCode:cardType', {}, {
            'query': { method: 'GET', isArray: true},
            'get': {
                method: 'GET',
                transformResponse: function (data) {
                    data = angular.fromJson(data);
                    return data;
                }
            }
        });
    });

我总是 'Failed to load resource: the server responded with a status of 404 (Not Found)'.

这里你少了 / .

你有两个路径变量here.so默认url是

localhost:8080/foo/bar/api/cardGenerated/FIRST_PATH_VARIABLE/SECOND_PATH_VARIABLE

branchCode（第一个路径变量）
cardType（第二个路径变量）

@RequestMapping(value = "/cardGenerated/{branchCode}/{cardType}"

并且在前端注册工厂定义时也出现了同样的错误。

api/cardGenerated/:branchCode/:cardType'

所有方法都像

@RestController
@RequestMapping("/api")
public class CardGeneratedResource {
@RequestMapping(value = "/cardGenerated/{branchCode}/{cardType}",
            method = RequestMethod.GET,
            produces = MediaType.APPLICATION_JSON_VALUE)
    @Timed
    public ResponseEntity<CardGenerated> get(@PathVariable("branchCode") String branchCode,
                                             @PathVariable("cardType") String cardType,
                                             HttpServletResponse response) {

        log.debug("REST request to get CardGenerated : " + branchCode + " and " + cardType);

        CardGenerated cardGenerated = cardGeneratedRepository.
                findTopByBranchCodeAndCardTypeOrderByCardNumberDesc(branchCode, cardType);

        if (cardGenerated == null) {
            return new ResponseEntity<>(HttpStatus.NOT_FOUND);
        }

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

和angular工厂就像

'use strict';

angular.module('itmApp')
    .factory('CardGenerated', function ($resource) {
        return $resource('api/cardGenerated/:branchCode/:cardType', {}, {
            'query': { method: 'GET', isArray: true},
            'get': {
                method: 'GET',
                transformResponse: function (data) {
                    data = angular.fromJson(data);
                    return data;
                }
            }
        });
    });

注意： 首先尝试使用任何 rest 客户端或邮递员，并确保后端 api 工作正常，angular 侧面检查参数也被正确传递.
