AngularJS和Spring

Question

我使用AngularJS将一个简单的表单发布到用Spring和Rest编写的API中。每个类都带有@RestController注解

我的spring Controller方法如下：

@RequestMapping(method = RequestMethod.POST)
public ResponseEntity<String> create(@Valid @RequestBody Modality modality) {
      mService.save(modality);

      return ResponseEntity.status(HttpStatus.CREATED).body("");
}

HTML表单：

<form ng-submit="submit()">
    <table>
        <tr>
            <td>Modality:.</td>
            <td><input type="text" name="modality" id="modality" ng-model="Modality.name" value="" /></td>
        </tr>
        <tr>
            <td>Active:.</td>
            <td><input type="checkbox" name="active" id="active" ng-model="Modality.active" value="" /></td>
        </tr>

        <tr>
            <td colspan="2">
                <button type="submit">Enviar</button> &nbsp;
                <input type="reset" value="Reset" /> &nbsp;
            </td>
        </tr>
    </table>
</form>

通过角度邮寄：

$scope.Modality = {id: null, name: '', active: ''}
$scope.submit = function() {
        $http({
            method: 'POST',
            headers : { 'Content-Type': 'application/json'},
            url: "http://localhost:8080/v1/modality",
            data: $scope.modality
        }).success(function(data) {
                console.log($scope.modality);
        });
}

当我使用角提交表单时，我可以看到表单数据填充了情态对象，但是当它到达spring控制器时，通道对象的所有属性都为空，因此，我ḿ得到了以下错误：

{"status":400, "error":"Badequest",
"exception":"org.springframework.http.converter.HttpMessageNotReadableException","message":"Required request body is missing: 
public org.springframework.http.ResponseEntity<java.lang.String>
cc.sporthub.controllers.ModalityController.create(cc.sporthub.models.Modality","path":"/v1/modality"}

我做错了什么？

我认为这是因为你使用的是小写的scope.modality。

Javascript变量区分大小写。

variables.asp
