Struts filter filters certain characters, struts filter filters (1) Some specific characters may need to be filtered out when tianchao's rules are used for project purposes. The following is a simple case of character filtering; (2) The filter code is as follows: Package com. lc. filter; import java. io. IOException; import javax. servlet. filter; import javax. servlet. filterChain; import javax. servlet

Create a project strutsdemo1 in eclipse. [For struts configuration, see struts development. The directory structure is as follows: Method 1 Create useraction package fzl.user.struts.demo;import com.opensymphony.xwork2.ActionSupport;public class UserAction extends ActionSupport {public String list(){System.out.println("list");return "success";}public String input(){System.out.println("input");return "s

In struts 1.0, we can only. specify a configuration file for actionservlet in XML, which is of course no problem for our online teaching examples. However, it may be troublesome in the actual application development process. Because many developers may need to modify the configuration file at the same time, but the configuration file can only be modified by one person at the same time, this will certainly cause resource competition to a certain extent

Sruts 2 workflow: All actions in struts 1 have only one instance, which is used repeatedly. Through the red font section of the workflow of struts 2 above, we can clearly see that each action in struts 2 has multiple instances, meaning that an action instance is generated every time a request is processed, these instances are independent of each other and will

Struts internationalization, struts Internationalization 1. Internationalization and Localization Internationalization: I18N: when the program is not modified, it can be used in different countries or regions and different language environments, display characters according to the local language and format habits.Localization: L10N: when developing an international program, the process of creating language-

Recently in doing Java EE project, need to encapsulate a lot of tags, found directly from the Bodytagsupport inherited words, can't get valuestack, also can't borrow struts internationalization solution. So you need to extend the label of struts. See a lot of online extension methods, feel can only be used as a reference or example, but it is not practical. Simpl

In the previous blog, I talked about how actionservlet is initialized and the specific role of Web. xml configuration information. Today we will continue to explain how actionservlet reads/WEB-INF/struts-config.xml information to memory during initialization and how to present the information read from the configuration file in the form of actionmapping in memory. Because this part of content is cumbersome, I cannot analyze it in detail, but I will e

Working mechanism: Struts workflow: When the web application starts, the initialization actionservlet will be loaded, and the actionservlet will Read configuration information in the struts-config.xml file and store them to various configuration objects When the actionservlet receives a customer request, it will execute the following process. -(1) retrieve the actionmapping instance that matches the us
