sreadlocals. 1, the Interceptor is based on the Java reflection mechanism, and the filter is based on function callback.2, the filter relies on the servlet container, and the interceptor does not depend on the servlet container.3. The interceptor can only function on the action request, and the filter works on almost

the specified method, and finds the interceptor corresponding to the action in Struts.xml. If there is a corresponding interceptor, these interceptors are called before the action's method executes, and if there is no corresponding interceptor, the action method is executed. The system's call to the Interceptor is imp

Struts 2 interceptor Proxy Mode Abstract topic: a common interface between a real topic and a proxy topic Real theme: Implements abstract theme and defines the real objects represented by the proxy role. Proxy topic: an abstract topic that contains references to a real topic role. A proxy role usually performs some operations before or after a client call is passed to a real topic object, instead of simply returning real objects. Dynamic proxy Mode 1

The Struts2 interceptor is the core of the struts2, and its underlying implementation uses the Java reflection mechanism and dynamic proxy.How to implement the Struts2 interceptor1.

does Spring provide the basic class webmvcjavaseradapter? We only need to override the addInterceptors method to add the register interceptor. Three steps are required to implement the custom Interceptor:1. create our own interceptor class and implement the HandlerInterceptor interface.2. Create a Java class that inhe

Since the work in the past two months has been relatively idle, I am also relatively "advanced", and I continue to learn about the difference between struts2 and struts1, why does struts1 use servlet while struts2 uses filter? What is the difference between Servlet and filter? So I looked at web. xml and found again, Servlet, filter, listener? Is there an interceptor? These concepts should have been mastered by beginners. Unfortunately, I am not good

Explore groovy mop nine interceptor 1 In recent years, AOP (Aspect-Oriented Programming) has been widely used. We have applied it to various aspects such as printing logs and permission control. When Implementing AOP, we generally use tools such as Spring AOP. Of course, tools are generally used to implement system-level AOP. Such implementations are generally implemented through configuration documents. When we need to implement a small range of AO
