Question

我正在尝试使用RESTClient类来发布RESTful Web服务。我在groovyx.net.http.HTTPBuilder $ RequestConfigDelegate的setBody上获得了一个NPE。

我的代码是

postParam = [
  sourceAccountNo         : fundTransfer.fromAccount.accountNumber,
  sourceBankCode          : fundTransfer.fromAccount.bank.bankCode,
  destinationBankCode     : fundTransfer.toAccount.bank.bankCode,
  destinationBankAccountNo: fundTransfer.toAccount.accountNumber,
  amount                  : fundTransfer.amount,
  narrationOne            : fundTransfer.note,
  uniqueId                : fundTransfer.uniqueId
]

String balanceTransferURL = ApplicationProperty.propertiesMap.get(ApplicationProperty.PropertyKey.BULK_BALANCE_TRANSFER_URL)
def restClient = new RESTClient(balanceTransferURL)
def restResponse = restClient.post(requestContentType:JSON,body:postParam)

我的错误日志如下

message: null
    Line | Method
->> 1200 | setBody                     in groovyx.net.http.HTTPBuilder$RequestConfigDelegate

|    140 | post                        in groovyx.net.http.RESTClient

究竟缺少什么？我做错了什么？

我遇到了同样的问题并发现当你添加requestContentType参数时它会消失：

import static groovyx.net.http.ContentType.JSON

requestContentType:JSON

为什么在尝试将JSON数据发布到宁静的Web服务时，RestClient会抛出空指针异常？
