3、第一种方式（设置私有属性）
log.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>Insert title here</title> </head> <body> <form action="login" method="post"> 用户名：<input type="text" name="userName"/> 密码：<input type="password" name="password"/> <input type="submit" value="提交"/> <input type="reset" value="重置"/> </form> </body> </html>
loginSuccess.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@ taglib uri="/struts-tags" prefix="s" %> <!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>Insert title here</title> </head> <body> 登陆成功，欢迎你：<s:property value="userName"/> </body> </html>
LoginAction类：
package com.ljb.web.action;
import com.opensymphony.xwork2.ActionSupport;
/**
* 第一种传递参数方法（设置私有属性，设置set与get方法）
* @author Administrator
*
*/
public class LoginAction extends ActionSupport {
private String userName;
private String password;
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
@Override
public String execute() throws Exception {
// TODO Auto-generated method stub
return SUCCESS;
}
}
struts.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> <!-- Add packages here --> <constant name="struts.devMode" value="true" /> <package name="default" namespace="/" extends="struts-default"> <action name="login" class="com.ljb.web.action.LoginAction"> <result> /loginSuccess.jsp </result> </action> </package> </struts>
4、乱码问题
login.jsp
<%@ page language="java" contentType="text/html; charset=gbk" pageEncoding="gbk"%> <!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=gbk"> <title>Insert title here</title> </head> <body> <form action="login" method="post"> 用户名：<input type="text" name="userName"/> 密码：<input type="password" name="password"/> <input type="submit" value="提交"/> <input type="reset" value="重置"/> </form> </body> </html>
loginSuccess.jsp
<%@ page language="java" contentType="text/html; charset=gbk" pageEncoding="gbk"%> <%@ taglib uri="/struts-tags" prefix="s" %> <!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=gbk"> <title>Insert title here</title> </head> <body> 登陆成功，欢迎你：<s:property value="userName"/> </body> </html>
