1>创建实体类

public class User {
    
    	private String uname;//用户名
    	private String upwd; //密码
    	private String truename;// 真实姓名
    	private String sex;// 性别
    	private String education;// 学历
    	private String province;// 省份
    	private String city;// 城市
    	private String favorite;// 爱好
    	private String fruit;// 喜欢吃的水果
    	private String language;// 编程语言
    ..............
    }

2>控制器ListAction类

public class ListAction extends ActionSupport implements SessionAware {
    
    	private User user;
    
    	public User getUser() {
    		return user;
    	}
    
    	public void setUser(User user) {
    		this.user = user;
    	}
    
    	/**
    	 * 跳转UI
    	 * 
    	 * @return
    	 * @throws Exception
    	 */
    	public String execute_ui() throws Exception {
    
    		return "ui";
    	}
    	
    	/**
    	 * 表单提交的数据
    	 * @return
    	 * @throws Exception
    	 */
    	public String execute_add() throws Exception {
    		System.out.println(user);
    		return "show";
    	}
