このようなJavaプログラム：
public void onUniformEvent(UniformEvent message, UniformEventContext uContext) {
try {
// single thread running
service.execute(new Runnable() {
public void run() {
try{
execute();
}catch(Exception e ){
logger.error("working error",e);
}
}
});
} catch (RejectedExecutionException e) {
logger.error("ProdStatusChangeTimeoutTaskListener:error", e);
} catch (Exception e) {
logger.error("ProdStatusChangeTimeoutTaskListener:error", e);
}
}
//omit the body
private void execute() {.....}
execute メソッドはスレッドを開始しません。

Excutors.newSingleThreadExecutor() を使用してバックグラウンドでクエリ ジョブを実行しています。次のタスクは 20 分間隔でこのエグゼキュータ サービスに送信されますが、クエリの実行中に作業スレッドがハングするように見えるため、次のタスクは実行されません。実行されます。それは数日間続き、例外は発生せず、ログ出力もまったくありません。誰かが私を助けることができますか? ありがとう
