m3 interceptor

1. Preface It is not familiar to hear interceptors, especially in the servlet specification, where the concept of interceptors is fully applied. EJB3 also provides interceptor support, which is essentially a lightweight AOP implementation that allows the interceptor to pull away common logic from business methods in multiple business methods and implement it in interceptors for excellent code reuse

In the previous article, I wrote about my own MVC framework, and then I talked about plugins and interceptors!In dealing with some common logic it is best to encapsulate a plugin or interceptor so that it can be used directly in the future. In my framework, you can implement plug-ins or interceptors by inheriting the following abstract classes.1. Aspectinterceptor Abstract classAn AOP interceptor that handl

InterceptorSpeaking of Interceptor, I believe that familiar with Struts2 's children's shoes will not be unfamiliar, struts2 can customize the interceptor to carry out their own desired series of related work. And the interceptor we're talking about here are pretty much the same function.Nonsense not to say, directly to the code:The following is the Myinterceptor

The order in which the Servlet filter and Spring interceptor are executed is the filter in order? How do we control the order in which filter is executed? Through Tomcat code analysis, the servlet is called after filter execution is complete, and if multiple filter controls the order of execution, the first thing to do is to configure a parameter in the Web.xml, like order, but find out, the servlet does not have this parameter. Try the configuration

The previous blog introduced the concept of interceptors and some of the basics of Struts2 and custom interceptors, but how exactly is the interceptor applied in the actual project, perhaps you are still confused, then this blog we will come up with actual combat, but also a summary of the interceptor and application practice. When we are doing any information management system, we can not avoid to control
