使用Struts2开发程序的步骤
1.导入jar包
<dependency>
<groupId>javaee</groupId>
<artifactId>javaee-api</artifactId>
<version>5</version>
</dependency>
<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-core</artifactId>
<version>2.3.4.1</version>
</dependency>
<dependency>
<groupId>org.apache.struts.xwork</groupId>
<artifactId>xwork-core</artifactId>
<version>2.3.4.1</version>
</dependency>
2.配置 web.xml文件
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" > <web-app> <display-name>Archetype Created Web Application</display-name> <filter> <filter-name>Struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>Struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
3.页面
<%@ taglib prefix="s" uri="/struts-tags" %> <%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title>Title</title> </head> <body> <s:form method="POST" action="userAction"> 请输入用户名： <s:textfield name="username"></s:textfield> <br/> <s:textfield name="password"></s:textfield><br/> <s:submit value="登陆"></s:submit> </s:form> </body> </html>
4.控制层
public class UserAction implements Action{ //SpringMvc Controller public String execute() throws Exception { return SUCCESS; } }
5.Struts2.xml
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd"> <struts> <package name="default" namespace="/" extends="struts-default"> <action name="userAction" class="cn.bdqn.action.UserAction"> <result name="success">/index.jsp</result> <result name="input">/login.jsp</result> </action> </package> </struts>
6.部署，运行项目
