Spring MVC中的PUT方法HTTP状态400-AngularJS

Question

我正在尝试更新Company对象，如下面的company.js所示。 当我尝试从company.js调用put方法时，它给了我400 Status错误 ，并且执行未在CompanyController.java的put方法中输入。 公司对象在$ scope中也可用。 在company.js中执行最终URL时： http：// localhost：8080 / Jobkreisel / protected / company / 50但它甚至没有输入CompanyController.java中的update方法，只需移至$ http中的错误块即可.put（url，$ scope.company，config）方法。

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。

Answer 1

web.xml是不完整的：确实，您需要/Jobkreisel/*到服务器的servlet映射。

只需按如下所示替换spring调度程序的<url-pattern>标签：

<!-- Spring servlet that will handle the requests-->
<servlet>
    <servlet-name>dispatcher</servlet-name>
    ...
</servlet>
<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/Jobkreisel/*</url-pattern>
</servlet-mapping>

如果调度程序的映射正确，则还可以更改从角度应用程序调用的url：

    var url = '/protected/company/' + $scope.company.companyID;
