JAVAlang.ArrayIndexOutofBounds异常:1未来。get()多线程
为什么我的应用程序会抛出错误
java.lang.ArrayIndexOutOfBoundsException: -1
当我召唤未来。java上的get()。乌提尔斯。同时发生的未来
List<Future> tableLoadings = new LinkedList<>();
ExecutorService executor = Executors.newFixedThreadPool(8);
try{
for(Entry<Integer, String> entry: farmIds.entrySet())
{
int id = entry.getKey();
String username = entry.getValue();
psLog.println("START ELABORAZIONE FARMACIA ID : "+ id+" TPH_USERNAME : "+username );
/*SdajSdaj*/
tableLoadings.add(executor.submit(new StatusMultiThreading(id, username, psLog, connSTORY, connCF, mongoDatabase)));
}
for (Future<Void> future : tableLoadings) {
try{
future.get();
}catch(Exception e){
psLog.println("[EE] ERORE ELABORAZIONE THREAD FARMACIA [EE] "+e.getMessage());
}
}
}finally{
executor.shutdown();
psLog.println("END CONSOLIDA STATUS FARMACIE");
}
这是日志
START ELABORAZIONE FARMACIA ID : 62 TPH_USERNAME : A0102987
START ELABORAZIONE FARMACIA ID : 63 TPH_USERNAME : A0103019
START SENDING DATA TO DB FARMID = 66
...
START SENDING DATA TO DB FARMID = 17
[EE] ERORE ELABORAZIONE THREAD FARMACIA [EE] java.lang.ArrayIndexOutOfBoundsException: -1
[EE] ERRORE ELABORAZIONE THREAD FARMACIA [EE] java.lang.ArrayIndexOutOfBoundsException: -1
END CONSOLIDA STATUS FARMACIE
如果我调试,我找不到任何错误
我不能进去。get()方法,所以我不知道哪行代码是无效的
# 1 楼答案
到目前为止可以说:您使用Executor服务传递任务:
稍后,当您调用
get()
时,会触发相应的任务。所以这个异常发生在你的类中
