//Controller.class
public static final Object lock = new Object();

String taskNo;
synchronized (lock) {
    taskNo = this.taskOrderManager.getTask(loginUser, getTask);
}
//TaskOrderManager.class
public String getTask(LoginUser loginUser, GetTask getTask)

在Controller层调用的时候加锁未生效，在实际调用的时候还是会有多个线程获取到相同的数据。
