SSH framework-Struts (3)-core methods for running Struts In the previous article, we talked about how to instantiate an ActionServlet for a single instance in Tomcat and perform initialization according to the web. xml configuration file. At this time, the client generates a request at the End of. do. After the request is submitted in get/post mode, no matter whi

The basic brief flow is as follows:1. The client browser makes an HTTP request.2, according to the Web. XML configuration, the request is filterdispatcher filtered.3. According to the Struts.xml configuration, find the action class and method that need to be called.4. Action invokes the business logic component to process the business logic.5, the action is completed, according to the configuration in the S

Configure the Web. xml file: 1. No matter how many sub-applications are included in the application, you only need to configure an actionservlet. Configuring multiple actionservlet classes to process different functions in an application is not necessary because the servlet itself supports multithreading. In addition, the current Struts framework allows only one actionservlet to be configured in the appli

If the server implements Singlethreadmodel by generating multiple instances of the servlet. This approach will fail completely beca

This article describes the common configurations and precautions of Struts. XML files.1. Use the A default struts. xml file is provided in struts2. However, if many configurations such as package, action, and interceptors are involved, it is not easy to maintain them in a single struts. xml file. Therefore, you need to

I want to do a login registration function under the SSH framework. Although there are many similar tutorials on the internet, I read a circle, either a version issue or missing many key steps. After several hours of hard work, we finally completed the so-called simple SSH integration to implement the registration function. Next we will share all the steps and hope to help our friends in need. The following uses a simple registration module as an example to describe the integration steps and con

, this also means that you must rewrite your application.◆ Add AJAX to your existing Struts application. Since AJAX is only a technology rather than a framework, it is easy to integrate into Struts. As an existing system, its stability, such as maintaining existing library files, is very important. Therefore, this method is recommended and will be detailed later. The advantages of adding AJAX to

This series of tutorials will detail the fundamentals and usage of struts 1.x, and readers can see the same points and differences between struts 1.x and struts 2.x in the Struts 2 series tutorial. First, this article gives the p

existing systems. • You can also directly adopt new methods, such as Direct Web Remoting (DWR) and Ruby on Rails, which are designed to build AJAX applications. If you do not consider using Struts for web development, these are all very useful frameworks and worth a try. However, this also means that you must rewrite your application. • Add AJAX to your existing Struts application. Since AJAX is only a t

complementary, so they decided to make the two work together. Developers can specify the tiles page definition as the target view for struts operations (according to strutsForward). Because both struts and tiles comply with the JSP tag library specifications, you can mix the struts tag and tiles tag on the JSP page. You may be eager to try the tiles framework an
