Question

我正在使用带有效负载的Postman发布POST：

{
"id" : "6",
"type" : "BUY",
"numOfShares" : "5000",
"pricePerShare" : "45.23",
"ticker" : "XYZ",
"commission" : "4.95",
"comments" : "Mgmt Change"
}

在REST控制器中处理我的POST的逻辑是：

@PostMapping("/transactions")
public Transaction addTransaction(@PathVariable Map<String, String> newTransaction){
    int transID = Integer.parseInt(newTransaction.get("id"));
    TransactionType transType;
    if(newTransaction.get("type").toUpperCase().equals("BUY")){
        transType = TransactionType.BUY;
    }else if(newTransaction.get("type").toUpperCase().equals("SELL")){
        transType = TransactionType.SELL;
    }else{
        transType = null;
    }

  ...MORE LOGIC HERE...

    return transMD.recordNewTransaction(new Transaction(transID,transType,transNumOfShares,
        transPricePerShare,transTickerSymbol,transCommission,transComments));
}

当我发布POST时，我得到＆＃34; java.lang.NumberFormatException：null＆＃34;在int transID = Integer.parseInt(newTransaction.get("id"));

当我在调试模式下运行应用程序并执行POST时，我可以看到当达到addTransaction()方法时，newTransaction映射为空（因此上面出现Null错误）。为什么地图不会被填充？

编辑：我明确添加到地图的单元测试工作：

@Test
public void makeNewTransaction() throws Exception{

    passedTransaction.put("id", "6");
    passedTransaction.put("type", "BUY");
    passedTransaction.put("numOfShares", "300");
    passedTransaction.put("pricePerShare", "37.23");
    passedTransaction.put("ticker", "XIV");
    passedTransaction.put("commission", "4.95");
    passedTransaction.put("comments","Testing Testing 1 2 3");

    Transaction newTrans = restCtrl.addTransaction(passedTransaction);
    assertEquals("XIV", newTrans.getSymbol());
}

POST时内部服务器错误。春季启动
