struts入门例子
具体步骤：
1、导入jar包
本例子基于一个基本的登录功能，只用到commons-beanutils.jar、commons-digester.jar、commons-logging.jar、struts.jar这四个jar包。
2、修改web.xml文件
在该文件增加<servlet><servlet/>和<servlet-mapping><servlet-mapping/>节点
3、创建和配置struts-config.xml
该文件和web.xml放在同一目录。
4、编写实现类和jsp页面
具体代码如下：
web.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
<display-name>Struts1</display-name>
<servlet>
<servlet-name>action</servlet-name>
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
<init-param>
<param-name>config</param-name>
<param-value>/WEB-INF/struts-config.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>action</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
</web-app>
LoginFormLoginFormLoginForm类：用于封装页面输入的表单信息
package form;
import javax.servlet.http.HttpServletRequest;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;
public class LoginForm extends ActionForm {
private String userId;
private String userName;
private String userPwd;
//恢复属性的初始状态
public void reset(ActionMapping mapping, HttpServletRequest request) {
this.userId = null;
this.userName = null;
this.userPwd = null;
}
public String getUserId() {
return userId;
}
public void setUserId(String userId) {
this.userId = userId;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getUserPwd() {
return userPwd;
}
public void setUserPwd(String userPwd) {
this.userPwd = userPwd;
}
}
LoginActionLoginActionLoginAction类：继承自org.apache.struts.action
package action;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import form.LoginForm;
public class LoginAction extends Action {
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
LoginForm loginForm = (LoginForm)form;
if(!loginForm.getUserName().equals("") && loginForm.getUserName().equals(loginForm.getUserPwd())){
request.getSession().setAttribute("userName", loginForm.getUserName());
return mapping.findForward("index");
}
return mapping.findForward("login");
}
}
struts-config.xml文件
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE struts-config PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 1.2//EN"
"http://struts.apache.org/dtds/struts-config_1_2.dtd">
<struts-config>
<form-beans>
<form-bean name="loginForm" type="form.LoginForm"></form-bean>
</form-beans>
<action-mappings>
<action path="/login" name="loginForm" type="action.LoginAction">
<forward name="index" path="/index.jsp" redirect="true"></forward>
<forward name="login" path="/login.jsp"></forward>
</action>
</action-mappings>
</struts-config>
登录页面 login.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>登录页面</title>
</head>
<body>
<form action="/Lesson11_Struts1Base/login.do" method="post">
用户名：<input type="text" name="userName"><br>
密码：<input type="password" name="userPwd"><br>
<input type="submit" value="提交">
</form>
</body>
</html>
首页index.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>首页</title>
</head>
<body>
欢迎你，${userName }
</body>
</html>
到此，一个struts例子基本完成。
