【问题描述】：

我是 angularjs 的新手。我正在尝试将来自 angularjs 的请求发布到 spring 控制器。请求对象以角度正确记录，但在控制器中达到 null。

我也遇到过类似的问题，但对我没有用：

getting null using angular post

angularjs-spring-mvc-json-post-request

spring-angularjs-receiving-null-data-on-server

Controller.js：

$scope.addExpense = function (expense) {
        console.log("Received"+expense.amount+expense.description);

        var expenseDetail = {
            description:expense.description,
            amount:expense.amount,
            created:'',
            updated:'',
        };

        console.log("expense detail : "+JSON.stringify(expenseDetail));

        $http({
            method  : 'POST',
            dataType: 'json',
            url     : 'addExpense1',
            data    : JSON.stringify(expenseDetail),
            headers: {
                "Content-Type": "application/json"
            }
        }).success(function (response) {
            console.log(response.data);
        }).error(function(response){
            console.log("Error : "+response.data);
        });
    };

控制器方法：

@RequestMapping(value = "addExpense1", method = RequestMethod.POST)
@ResponseBody
public List<ExpenseDetail> addExpense1(@RequestBody ExpenseDetailDTO expenseDetailDTO) {
    LOG.info("Request to add description : " + expenseDetailDTO.getDescription());
    if(expenseDetailDTO==null || expenseDetailDTO.getDescription()==null || expenseDetailDTO.getAmount()==null)
        return null;
    expenseService.addExpense(expenseDetailDTO);

    List<ExpenseDetail> expenseDetails = expenseService.getAllForToday();
    LOG.info("Expense Details fetched : " + expenseDetails.size());
    return expenseDetails;
}

在控制器上打印以下日志：

Request to add description : null

我在任何地方都没有出错。请帮帮我。
