[英]Unreported exception … must be caught or declared to be thrown; despite *thrown* keyword
我有一个方法被定义为:
private void startUSSDNotification(SimpleReference reference,
String ussdServiceActivationNumber,
String criteria)
throws PolicyException {
// Note that the injected javax.xml.ws.Service reference as well as port objects are not thread safe.
// If the calling of port operations may lead to race condition some synchronization is required.
USSDNotificationManager port = service.getUSSDNotificationManager();
port.startUSSDNotification(reference, ussdServiceActivationNumber,
criteria);
}
编译器发牢骚,“未报告的异常PolicyException;必须被捕获或声明为抛出。我不知道为什么它建议我可以抛出但方法签名中仍然存在” throw”。
startUSSDNotification
定义为:
public void startUSSDNotification(
@WebParam(name = "reference", targetNamespace = "http://www.csapi.org/schema/osg/ussd/notification_manager/v1_0/local")
SimpleReference reference,
@WebParam(name = "ussdServiceActivationNumber", targetNamespace = "http://www.csapi.org/schema/osg/ussd/notification_manager/v1_0/local")
String ussdServiceActivationNumber,
@WebParam(name = "criteria", targetNamespace = "http://www.csapi.org/schema/osg/ussd/notification_manager/v1_0/local")
String criteria)
throws PolicyException, ServiceException
;
当我尝试将调用包装在try ... catch中时,错误仍然存在,并且会弹出另一个错误,指出try的主体从未抛出Exception异常。 我该如何补救? 我正在使用javase7和netneans 8
由于您没有向我们展示实际的编译错误等,因此不能确定,但是我怀疑有多个类称为PolicyException
,并且您在声明错误的类:
检查编译错误的准确措辞
检查您的import
声明。
