1.struts.xml文件配置action
<action name="LoginView" class=""> <result>/WEB-INF/login/login.jsp</result> </action> <action name="UserLoginAction" class="com.bict.action.Login"> <result name="success">/WEB-INF/login/success.jsp</result> <result name="error">/WEB-INF/login/error.jsp</result> </action>2.登录页面login.jsp
<form action="UserLoginAction.action" method="post"> <label>用户名:</label><input type="text" name="username"/><br/> <label>密码:</label><input type="password" name="password"/><br/> <input type="submit"/> </form>3.Login处理用户请求，通过ActionContext对象访问web应用的Session,返回一个Map
package com.bict.action; import com.opensymphony.xwork2.ActionContext; import com.opensymphony.xwork2.ActionSupport; public class Login 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(){ if(getUsername().equals("linbo") && getPassword().equals("123456")){ ActionContext.getContext().put("user", getUsername());//通过ActionContext对象访问web应用的Session,返回一个Map return SUCCESS; }else{ return ERROR; } } }4.在success.jsp页面中使用JSP语法输出Session中user属性
欢迎，${sessionScope.user}您已经登录!
