Introduced As we all know, AOP (facet-oriented programming) is one of the features of the spring framework. AOP provides extremely high scalability by setting crosscutting concerns (cross cutting concerns). So how does AOP work in spring? When you can only use core Java, but you need AOP technology, the answer to this question becomes extremely critical. Not only that, but in interviews with senior technic

code, the thread can call the object's Wait () method, release the object lock flag, enter the wait state, and call the Notify () or the Notifyall () method to notify other threads that are waiting. Notify () notifies the first thread in the wait queue. Notifyall () Notifies all threads waiting on the queue.The Wait () and notify () mechanisms provided in Java are as follows:Called by thread 1 synchronized method1 (...){//Access data variable availab

0. About thread synchronization(1) Why do I need to sync multithreading?thread synchronization is to allow multiple running threads to work together in a good way to allow multithreading to properly occupy released resources as required. We use the synchronized code block and synchronization method in Java to achieve this goal. For example, this solves the problem that multithreading has no fixed order execution: public class Twothreadtest {pu
