怎么可以解决诡计：未经检验/未经证实的声纳投射？ [英] how can resolve dodgy:unchecked/unconfirmed cast in sonar?

问题描述

我在下面的代码中通过声纳得到异常。我如何解决这个问题。

  @Override 
 public boolean validate（BaseInfo infoObject）{
 boolean isValid = true; 
 AckTransferPaymentInfo ackTransferPaymentInfo =（AckTransferPaymentInfo）infoObject; 
  

Dodgy - 未选中/未确认的演员

从com.vocalink中取消选中/未确认的演员.acsw.common.validation.info.BaseInfo to com.vocalink.acsw.common.validation.info.AckTransferPaymentInfo in com.vocalink.acsw.validation.rule.T170Rule.validate（BaseInfo）

  AckTransferPaymentElement payment = ackTransferPaymentInfo.getTransferPayment（）; 
 if（CreditDebitIndicator.CRDT.equals（ackTransferPaymentInfo.getCreditDebitIndicator（））
&& ackTransferPaymentInfo.getOriginalPaymentAccount（）。getAccountName（）！= null 
  / pre> 
 
解决方案
您可以检查infoObject的类型是否正确，如果不是，请妥善处理：
  if（！（infoObject instanceof AckTransferPaymentInfo））{
 throw new AssertionError（Unexpected type：+ infoObject）; 
 } 
 AckTransferPaymentInfo ackTransferPaymentInfo =（AckTransferPaymentInfo）infoObject; 
  
你应该验证这样做你想要的当infoObject为null时。
 
iam getting the exception through sonar in this following code.How can I resolve this.Suggest me. 
    @Override 
     public boolean validate(BaseInfo infoObject) { 
     boolean isValid = true; 
     AckTransferPaymentInfo ackTransferPaymentInfo = (AckTransferPaymentInfo) infoObject; 
Dodgy - Unchecked/unconfirmed cast

Unchecked/unconfirmed cast from com.vocalink.acsw.common.validation.info.BaseInfo to com.vocalink.acsw.common.validation.info.AckTransferPaymentInfo in com.vocalink.acsw.validation.rule.T170Rule.validate(BaseInfo) 
AckTransferPaymentElement payment = ackTransferPaymentInfo.getTransferPayment();  
if(CreditDebitIndicator.CRDT.equals(ackTransferPaymentInfo.getCreditDebitIndicator()) 
&& ackTransferPaymentInfo.getOriginalPaymentAccount().getAccountName() != null 

解决方案
You can check that the type of infoObject is correct and handle it appropriately when it's not:
if (!(infoObject instanceof AckTransferPaymentInfo)) {
    throw new AssertionError("Unexpected type: " + infoObject);
}
AckTransferPaymentInfo ackTransferPaymentInfo = (AckTransferPaymentInfo) infoObject;
You should verify this does what you want when infoObject is null.
