1.屬性驅動
User.java
package com.qwl.domain; public class User { 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; } }
UserLogin.java
package com.qwl.action; import com.opensymphony.xwork2.ActionContext; import com.opensymphony.xwork2.ActionSupport; import com.qwl.domain.User; public class UserLoginAction extends ActionSupport { private User user; public User getUser() { return user; } public void setUser(User user) { this.user = user; } public String excute() throws Exception{ ActionContext context =ActionContext.getContext(); if("itcast".equals(user.getUsername())&&"123".equals(user.getPassword())){ context.getSession().put("username", user.getUsername()); context.getSession().put("password", user.getPassword()); return SUCCESS; }else{ context.getSession().put("error", "使用者登入失敗"); return ERROR; } } }
