使用Springboot test进行相关测试的时候，发现开启线程操作数据库的时候异常。
将线程移除，采用并行的方式，操作数据库正常。
提供一个全局的线程池，然后使用线程池开启线程操作，然后添加监听器，监听线程池里面是否有未完成的任务，如果有则不关闭容器。
@Component
public class EventListener implements ApplicationListener<ApplicationEvent> {
@Override
public void onApplicationEvent(ApplicationEvent event) {
if (event instanceof ContextClosedEvent) {
LoggerClient.info("容器即将关闭");
//线程池工具类
ThreadPoolUtil threadPoolUtil = new ThreadPoolUtil();
while (threadPoolUtil.getExecutor().isTerminated()) {
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
}
public class ThreadPoolUtil {
private static final ExecutorService executor = Executors.newFixedThreadPool(20);
public ThreadPoolUtil() {
}
public ExecutorService getExecutor() {
return executor;
}
public static void submitRunnable(Runnable runnable) {
executor.submit(runnable);
}
public static <V> Future submitCallable(Callable<V> callable) {
Future<V> submit = executor.submit(callable);
return submit;
}
}
