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.
