There are a lot of Java beginners for the MyBatis interceptor Inteceptor is not very understanding, here I will organize the next chapter on the Java MyBatis Interceptor Inteceptor detailed, This paper mainly analyzes the plug-in mechanism of mybatis, in fact, is the implementation of the responsibility chain model of Java dynamic Proxy implementation. According to the official document. MyBatis only allo

And of course there are many interceptor stacks, so let's look at the interceptor first. Interceptor name Aliasinterceptor "Alias Blocker" Configuration name Alias Describe Allows parameters to use different aliases across multiple requests, which can be used to link multiple actions with different names, and

Learn notes for the action before the interceptor or after the interceptor. from After the teacher's test ... Add breakpoints to each interceptor ...Know: The Action is executed at the time of the visit. And the action is created before the params interceptor is executed. So the conclusion is: Action must precede the

The struts2 interceptor is one of the core functions of the struts framework. First, the automatic data filling function implemented by the struts framework is implemented by the interceptor. Here we will summarize the experiences of the blocker during this period. It is obvious that the interceptor must be pre-processed or post-processed. The parameter filling i

Interceptor systemIs an important part of the struts2 framework, a large numberBuilt-in interceptorCompleted most of the operations on the framework. For exampleParamsThe Interceptor is responsible for parsing HTTP Request Parameters and setting Action attributes;ServletconfigThe interceptor directly transmits the httpservletrequest instance and httpservletrespon

Interceptors are the struts2 core, and many functions are implemented by interceptors. I. Write a interceptor yourself Write the interception in the Interceptor method two. Configuring Interceptors in Struts2.xml Write the Note： The interceptor in the STRUTS2 is similar to the servlet filter, but the Struts2

In the previous article, we introduced how to use unity to take over piab for interception, while Unity itself also provides interception processing similar to icallhandler.Program-- Iinterceptionbehavior, today's articleArticleIt is mainly about how to use iinterceptionbehavior and the built-in interceptor of unity. The following is what we will introduce: 1. Create a custom interceptionbehavior 2. Advantages and disadvantages of the thr

Turnhttp://www.cnblogs.com/wangyuyu/archive/2013/07/02/3167354.html1, interceptors are based on the reflection mechanism of Java, and filter is based on function callback2. The filter relies on the servlet container, while the interceptor does not depend on the servlet container3. Interceptors only work on action requests, while filters can work on almost all requests4. The interceptor can access the action

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
