This article will explain in detail what the Servlet advice on thread safety is. The content of the article is of high quality, so the editor will share it with you for reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

1. Use only local variables in Servlet as much as possible

2. You should only use read-only instance variables and static variables

3. Do not create your own thread in Servlet

4. When modifying shared objects, use synchronization to narrow the scope of synchronization code as much as possible, and do not synchronize directly on the service () method or doXXX () method, so as not to affect performance.

5. If you want to modify external objects (for example, files) in multiple different Servlet, lock them and make mutually exclusive access.

Thread-safe Servlet advice on what is shared here, I hope that the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
