The difference between interceptors and filters

1. Interceptors are based on the reflection mechanism of Java, and filters are based on function callbacks.
2. Interceptors are not dependent on the servlet container, and the filter relies on the servlet container.
3. Interceptors only work on action requests, while filters can work on almost all requests.
4. The interceptor can access the action context, the object in the value stack, and the filter cannot be accessed.
5. Interceptors can be called multiple times during the life cycle of an action, and filters can only be called once when the container is initialized
