strust2demo

1)首先新建一个web工程:struts2demo

2)在此web工程webcontent下WEB-INF,lib下导入必要的jar，文件：commons-logging-1.1.jar;ognl-206011.jar;struts2-core-2.0.6.jar;xwork-2.0.1.jar;

3)web.xml文件添加如下：

<filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
    </filter>

    
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

4）WebContent目录下复制文件：

<%@ page language="java" contentType="text/html; charset=UTF-8"%>
<%@taglib prefix="s" uri="/struts-tags"%>
<html>
<head>
<title><s:text name="loginPage"/></title>
</head>
<body>
<s:form action="login">
            <s:textfield name="username" key="user"/>
            <s:textfield name="password" key="pass"/>
            <s:submit key="login"/>
</s:form>
</body>
</html>

error.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"%>
<%@taglib prefix="s" uri="/struts-tags"%>

<html>
    <head>
        <title><s:text name="errorPage"/></title>
    </head>
    <body>
        <s:text name="failTip"/>
    </body>
</html>

welcome.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"%>
<%@taglib prefix="s" uri="/struts-tags"%>
<html>
    <head>
        <title><s:text name="succPage"/></title>
    </head>
    <body>
        <s:text name="succTip">
            <s:param>${sessionScope.user}</s:param>
        </s:text><br>
    </body>
</html>

5)src目录下添加文件：

messageResource_zh_CN.properties，struts.properties，struts.xml

内容分别如下：

loginPage=登陆页面
errorPage=错误页面
succPage=成功页面
failTip=对不起，您不能登录！
succTip=欢迎，{0},您已经登录！
viewLink=查看作者李刚已出版的图书
bookPageTitle=作者李刚已出版的图书
bookName=书名：
user=用户名
pass=密码
login=登陆
user.required=用户名必须输入！
pass.required=密码必须输入！

6）loginAction.java

package lee;

import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ActionContext;

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;
	}

	public String execute() throws Exception {
		if (getUsername().equals("scott") && getPassword().equals("tiger")) {
			System.out.println("getUsername()===>"+getUsername());
			ActionContext.getContext().getSession().put("user", getUsername());
			return SUCCESS;
		} else {
			return ERROR;
		}
	}

}
