java中调用feign client api异常时如何继续程序

Question

public string prospect(List<ProspectRequest> prospectRequest, String primaryClientId) {
    if(p2p(primaryClientId)=="Success") {
        for(ProspectRequest prospect : prospectRequest) {
            p2p(prospect.getId());
       }
   // rest of code i would like to continue
    }
 }

public string p2p(String id){
crmApi.getProspectId(id);//this is external client api
String message = "Success"; 
return message;
}

如果 p2p(primaryClientId) 失败，那么我需要停止整个过程。我想如何继续“我想继续的其余代码”。

如果伪装客户端 api crmApi.getProspectId 成功，则返回成功消息，这是一个很好的例子。如果 crmApi.getProspectId api 给出错误，那么我仍然需要为下一组客户端继续 p2p() 程序。这是如何工作的。

提前致谢。

看来你只需要使用 try catch finally 块

  public string prospect(List<ProspectRequest> prospectRequest, String primaryClientId) {
  

    try {
      if(p2p(primaryClientId)=="Success") {
         for(ProspectRequest prospect : prospectRequest) {
            p2p(prospect.getId());
        }
    } catch (RuntimeException e) {}  // Exception can be specified exp. RuntimeException
    finally {
       // rest of code i would like to continue
    }
    }
 }

public string p2p(String id){
crmApi.getProspectId(id);//this is external client api
String message = "Success"; 
return message;
}

如果您需要第一个 if 块中的某些内容，您可以在 catch 块中放置一个选项（如果 if 块失败）。当

if(p2p(primaryClientId)=="Success") {
             for(ProspectRequest prospect : prospectRequest) {
                p2p(prospect.getId());
            }

抛出检查异常需要将 RuntimeExpection 更改为超类 Exception

已编辑：

 for(ProspectRequest prospect : prospectRequest) {
      try {
        p2p(prospect.getId());

} 赶上（RuntimeExpection e）{} }
