using interceptors In web development we often encounter paging operations, a project may have more than one use to paging, then if the Java background using MyBatis as a persistence layer, we can use the MyBatis interceptor function to complete the entire project in multiple paging operations, reduce the code redundancy.

1. What is an interceptor:Interceptor, used in AOP (Aspect-Oriented Programming) to intercept a method or field before it is accessed, and then add some operations before or after it. Interception is an implementation policy of AOP. 2. Struts2 default interceptor Stack: Interceptor Name Description Alias Interceptor Alias The reques

Today, I spoke to several Java-loving students about struts2 and focused on its most valuable interceptor. I don't know whether you can remember it. In struts2 server-side verification, I said, "The verification has been completed before arriving at the login action ". I hope someone can raise the question, so that I can say that this is the benefit of the interceptor, so we can study the

Downpour writes that interceptors are the concept of AOP, which is itself a piece of code that can be used to intercept the code of the Interceptor by defining the "weaving point" to execute before and after the "weaving point". As reference in Struts2 above, Struts2 's interceptor, the object of its interception is the action code, which can define the code that executes the

values from Valuestack and Actioncontext 1. Take the value from the Valuestack. Note that the value in this Value property, name, is actually the ONGL expression//This represents a property value from Valuestack named name 2) You can also use the previous method to extract values from the request, session, and application.Note: If we use the request through key to fetch value, will first in request inside, request inside find not to valuestack inside. Because Valuestack is also placed in the re

The Interceptor interceptor in SPRINGMVC is also very important and useful, and its main function is to intercept the user's request and handle it accordingly. For example, through it to verify the permissions, or to determine whether the user is logged on, or if the current time is like 12306 to determine whether the purchase time. first, define the interceptor

Shiro Learning (8) interceptor mechanism 8.1 Introduction to interceptorShiro uses the same Filter interface as Servlet for extension. If you are not familiar with the Filter, refer to Servlet3.1 specifications http://www.iteye.com/blogs/subjects/servlet-3-1to understand the working principle of filtering. The first is the basic class diagram of the Shiro Interceptor:1. NameableFilterNameableFilter gives th

Software design dry rules, that is, do not write repetitive code, which can greatly reduce the workload of late maintenance. But the problem is, duplicate code is unavoidable, such as the user before sending a request to determine whether the user login, how to do it. The duplicate code is then extracted and encapsulated into a method A, which avoids writing duplicate code, and the user simply calls method a before sending the request. But again, the problem arises, the user may call method A be

Use of interceptor in SpringMVC The Interceptor in SpringMVC is also very important and useful. Its main function is to intercept user requests and process them accordingly. For example, you can use it to perform permission verification, or to determine whether the user logs in, or to determine whether the current time is the time when the user buys the ticket, as shown in Figure 12306.1. Define the
