defined in actionsupport. Four string attributes are defined in actionsupport, namely success, input, error, and login. In this way, our action has been completed, but there is still a problem. How can we let struts2 know our custom action, and can I submit the action to the action on the HTML/JSP page? The answer is to configure the Struts. xml file. 4. Configure struts. xml In this struts. xml configuration file, it can be found that and the previous struts-config.xml has been compl

Automatic prompt for strust. xml code in MyEclipse, and prompt for myeclipse code 1. Open the MyEclipse Window and select the "Preferences" option under the "Window" menu, 2. Search for "xml" in the "Preferences" interface, select the "XML Catalog" option, and then select the "Add..." button on the right. 3. In the displayed dialog box, enter struts in "location. the location of the dtd file corresponding to the xml file. It is recommended that you

    ActionForm is essentially a javabean, which is used to process form data. According to some characteristics of form data, ActinForm also has some special functions, such as validate () used to process form data verification and reset () for data

The action class is a bridge between user requests and business logic, and each action acts as a business agent for the customer. When you requestprocessor a class preprocessing request, after you create an instance of the action, you call its own

The struts framework allows only one Actionservlet class to exist in the application, but there can be multiple, customized requestprocessor classes, each of which can have a separate requestprocessor class. Actionservlet is primarily responsible

As we all know, the Struts controller component is responsible for accepting user requests, for more models, and for returning the appropriate view components to the user.The controller separates the model layer from the view layer so that different

Recently I think idea is a good Java development tool, so I tried to switch from myeclipse to idea. After I used it, I found that it was really good. The Code prompts and interfaces were quite good, so I used idea to develop a Java Web project. By the way, I recorded the process of setting up the strust project in idea. Step 1: Open Idea and select create new project. Step 2: configure the Tomcat server. Click new> Tomcat server on the right of appl

Strust is equivalent to an empty container, and the built-in interceptor completes most of the operations on the framework. The struts2 interceptor is pluggable. To use an interceptor, you only need to apply it to the configuration file. If you do not need it, cancel it in the configuration file. Configure the interceptor Syntax: interceptor-stackname Strust is equivalent to an empty container, and the buil

A small Strust2 example Then I found that css, js, and images could not be used. I found that I could not access these resources (404 error) under debugger. That is a good example. I should look at the pictures in the book at least. It is found that the filter problem in web. xml is as follows: Web. xml The red part of the code filters out All accesses. Isn't access to css, js, and other resources filtered out? But the example in that book is written in this way. Is Mao !!. Mom. The

core controller of Strust, which is responsible for intercepting the user's request. Action, which is typically provided by the user, is responsible for receiving the request from Actionservlet and invoking the business logic method of the model to process the request and returning the processing results to the JSP page display. The 2.Model part consists of Actionform and JavaBean, wherein Actionform is used to encapsulate the user's request paramete

Before learning Strust2, we should understand the purpose of using STRUTS2? What benefits can it bring to us?Design goalsThe first goal of Strust design is to apply the MVC pattern to Web programming.Technical advantagesSTRUTS2 has two technical advantages.One is that all STRUTS2 applications are based on the Client/server HTTP exchange protocol, the Java Servlet API reveals that Java servlet is just a small subset of the Java API, This allows us to p

() to return a value not greater than 127. Conclusion It makes some programs wrong, but does not give developers any way to tell their code whether to execute these actions. If it is where it is, it is basically evil. One of the design points of C is "Trust programmers ". This is good, but there is confidence and then trust (there 'strust and then there's trust ). I mean, I trust my 5-year-old child, but I still won't let him walk alone through a bu

I recently learned ASP. NET MVC and compared the previous WebForm with no IsPostBack judgment, event processing is also replaced by Action. In the WebForm of MVC, a large number of events are bound to the UI, mixed js injection, and style changes are gone; the server control is no longer needed, and the View is released, the Controller can be tested in units, and the View can be quickly replaced with the ViewModel. (To be honest, it would not have been a page engine like Razor and powerful intel

Because the company uses SSH for projects, to understand how SSH is built and how it works, we have built one by ourselves. Build a simple struts2 + spring + hibernate environment using the minimal jar package as much as possible. I hope that anyone like me can understand it. If you have used similar MVC patterns such as Microsoft MVC, it is much easier to understand. First, I am using myeclipse 9 + Tomcat 6 (it is said that Tomcat and struts are incompatible, but I did not meet it, I do not kno
