Question

如何使用grails创建JSON数组，如下所示：

{"paymentRequestlist":[{"sourceAccountNo":"555555555555555","sourceBankCode":"GLBBNPKA","destinationBankCode":"GLBBNPKA","destinationBankAccountNo":"123456789111111","corporateName":"","amount":14000,"remarks":"","narrationOne":"fund transfer initiated by maker 1","narrationTwo":"","uniqueId":"ESW-COR:1405491430740"},{"sourceAccountNo":"555555555555555","sourceBankCode":"GLBBNPKA","destinationBankCode":"GLBBNPKA","destinationBankAccountNo":"123456789111111","corporateName":"","amount":13000,"remarks":"","narrationOne":"fund transfer initiated by maker 1","narrationTwo":"","uniqueId":"ESW-COR:1405491430740"}]}

到目前为止，我已尝试使用grails.converters.JSON构建一个数组，如下所示：

JSONArray postParamsArray = new JSONArray()

JSONObject postParams = new JSONObject();
            postParams.put('sourceAccountNo',fundTransfer.fromAccount.accountNumber);
            postParams.put('sourceBankCode',fundTransfer.fromAccount.bank.bankCode);
            postParams.put('destinationBankCode',fundTransfer.toAccount.bank.bankCode);
            postParams.put('destinationBankAccountNo',fundTransfer.toAccount.accountNumber);
            postParams.put('corporateName','');
            postParams.put('amount',fundTransfer.amount);
            postParams.put('remarks','');
            postParams.put('narrationOne',fundTransfer.note);
            postParams.put('narrationTwo','');
            postParams.put('uniqueId',fundTransfer.uniqueId);

 postParamsArray.add(postParams);

P.S。我对grails完全不熟悉!!任何建议都会有很大的帮助

Answer 1

您可以创建地图（更容易）并将其转换为JSON

简单（未经测试）的例子

def json = ['paymentRequestlist':[
   ['sourceAccountNo': valueForSourceAccountNo1,
    'sourceBankCode': valueForSourceBankCode1,
    ...
   ],
   ['sourceAccountNo': valueForSourceAccountNo2,
    'sourceBankCode': valueForSourceBankCode2,
    ...
   ]]
] as grails.converters.JSON

Answer 2

使用以下代码填写您的代码：

JSONObject completeJson = new JSONObject()
completeJson.put("paymentRequestlist",postParamsArray)

println completeJson as JSON

如何通过GRAILS构建如下所述的JSOn数组？
