这是我的代码：
public void deletevendor(VendorEntity vendorEntity) throws Exception {
CompletableFuture<Void> future = CompletableFuture.runAsync(() -> {
try {
dwService.deleteVendor(vendorEntity);
} catch (Exception ex) {
log.info("Error occurred ", ex);
}
});
Boolean isCancelled = future.isCancelled();
Boolean isDone = future.isDone();
Boolean isCompletedExceptionally = future.isCompletedExceptionally();
System.out.println("Asynchronous CompletableFuture: " + isCancelled +" "+ isDone+" "+ isCompletedExceptionally );
}
我在try块中的代码运行正常。我想触发catch块。我该怎么做。可以触发我的完全未来异常的输入是什么？
为了对< code>Future进行实验，这是您触发< code>catch子句的方式:
CompletableFuture<Void> future = CompletableFuture.runAsync(() -> {
try {
throw new Exception("");
} catch (Exception ex) {
log.info("Error occurred ", ex);
}
});
根据您的代码片段，如前所述，整个异常抛出逻辑都在内部调用dwService。deleteVendor（vendorEntity）方法。这意味着您必须将一个特定的vendorEntity传递到这个public void deletevendor（vendorEntity vendor实体）method中，以便抛出在
