Spring MVC中的PUT方法HTTP Status 400-AngularJS

我正在尝试更新Company对象，您可以在下面的Company.js中看到。当我试图从company.js调用put方法时，它会给我400状态错误，并且执行不会进入CompanyController.java中的put方法。公司对象也在$scope中可用。执行company.js中的最终URL时：http://localhost:8080/Jobkreisel/protected/company/50但它甚至没有进入CompanyController.java中的更新方法，只是移动到$http.put（url，$scope.company，config）方法中的错误块。

company.js

  $scope.updateCompany = function (updateCompanyForm) {
        if (!updateCompanyForm.$valid) {
            $scope.displayValidationError = true;
            return;
        }
        $scope.lastAction = 'update';
        var url = '/Jobkreisel/protected/company/' + $scope.company.companyID;

        var config = {};
        alert("Company scope "+$scope.company.companyID);
        alert("Company config "+config);
        $http.put(url, $scope.company, config)
            .success(function (data) {
                alert('In update success');
            })
            .error(function(data, status, headers, config) {
                console.debug(data);
                alert('data:' + data);
                alert('status: ' + status); 
                alert('update error');
            });
    };

CompanyController.java

@Controller
@RequestMapping(value = "/protected/company")
public class CompanyController extends UserBaseController {
    @Autowired
    private CompanyService companyService;
    @RequestMapping(value = "/{companyID}", method = RequestMethod.PUT, produces = "application/json")
    public ResponseEntity<?> update(@PathVariable("companyID") int companyId,
                                    @RequestBody Company company,                                    
                                    Locale locale) {
        if (companyId != company.getCompanyID()) {
            return new ResponseEntity<String>("Bad Request", HttpStatus.BAD_REQUEST);
        }
        companyService.save(company);
        return null;
    }
}

请告诉我为什么它不执行成功块。
