Angular HTTP和Spring Boot Rest服务

我正在从我的有角度的UI调用spring boot REST服务。只要将Spring Boot Rest服务作为Spring Boot应用程序执行，它就可以很好地工作。但是，一旦将其转换为WAR文件并部署到Jboss 6.2.4服务器上，我就会得到404。我看到从UI进行的REST服务调用成功了，但是请求JSON没有被传递。在请求JSON上，我传递了2个字符串和一个上载的excel文件。

这是我的角度UI http调用

App.service('getHeatMapDataService', ['$http', '$q', function ($http,      $q) {
this.getHeatMapData = function (scope) {
    var url = 'http://localhost:8080/rest-services/fusiontables/upload';
    var deferred = $q.defer();
    $http({
            method: 'POST',
            url: url,
            headers: {
                'Content-Type': undefined
            },
            data: {
                stateCd: scope.stateCd,
                addressExtras: scope.addressExtras,
                uploadFile: scope.upFile
            },
            transformRequest: function (data, headersGetter) {
                var formData = new FormData();
                angular.forEach(data, function (value, key) {
                    formData.append(key, value);
                });

                var headers = headersGetter();
                delete headers['Content-Type'];
                return formData;
            }
        })
        .success(function (data) {
            deferred.resolve(data);
            console.log("Success");
            console.log(data);
        })
        .error(function (data, status) {
            deferred.reject(status);
            console.log("Failed");
        });
    return deferred.promise;
}
}]);

这是我的Spring Boot Rest控制器在工作时

@RequestMapping(value="/upload", method=RequestMethod.POST)
@ResponseBody
public String getBoundaries(HeatMapUploadCommand uploadCommand) {
    logger.info("Heat Map Controller invoked " + uploadCommand);
    return null;
}

这是我的上传命令

public class HeatMapUploadCommand {

private String stateCd;
private String addressExtras;
private MultipartFile uploadFile;

当我在Jboss上部署之后，请求仍然会触发Spring Boot应用程序，但是所有请求参数都为null。

这是请求有效负载

------WebKitFormBoundaryvCCnl3nhIgoW1MwR
Content-Disposition: form-data; name="stateCd"

CA
------WebKitFormBoundaryvCCnl3nhIgoW1MwR
Content-Disposition: form-data; name="addressExtras"

1234
------WebKitFormBoundaryvCCnl3nhIgoW1MwR
Content-Disposition: form-data; name="uploadFile"; filename="CAdata.xlsx"
Content-Type: application/vnd.openxmlformats-    officedocument.spreadsheetml.sheet


------WebKitFormBoundaryvCCnl3nhIgoW1MwR--

我尝试将控制器更改为

@RequestMapping(value="/upload", method=RequestMethod.POST)
@ResponseBody
public String getBoundaries(@RequestParam(value="stateCd") String stateCd,
        @RequestParam(value="addressExtras") String addressExtras,
        @RequestParam(value="uploadFile") MultipartFile file) {
    System.out.println("Heat Map Controller invoked " + stateCd);
    return null;
}

仍然没有运气。这是我得到的回应。

{"timestamp":1464840821648,"status":400,"error":"Bad    Request","exception":"org.springframework.web.bind.MissingServletRequestParameterException","message":"Required String parameter 'stateCd' is not     present","path":"/rest-services/fusiontables/upload"}

终于想通了。

我必须添加一个Multipartresolver bean。

@Configuration
public class WebConfig extends WebMvcAutoConfiguration {
@Bean
public MultipartResolver multipartResolver() {
    return new CommonsMultipartResolver();
}

}

这解决了问题。好像当我将其作为spring boot应用程序运行时，spring已经照顾好了它，但是当部署为WAR文件时，应配置此bean
