1.反向工程生成用户实体类

User.java

package com.sunline.entity;
    /**
     * User entity. @author MyEclipse Persistence Tools
     */
    
    public class User  implements java.io.Serializable {
    
    
        // Fields    
    
         private Integer userId;
         private String userName;
         private String userPassword;
         private String userStatus;
    
    
        // Constructors
    
        /** default constructor */
        public User() {
        }
    
        
        /** full constructor */
        public User(String userName, String userPassword, String userStatus) {
            this.userName = userName;
            this.userPassword = userPassword;
            this.userStatus = userStatus;
        }
    
       
        // Property accessors
    
        public Integer getUserId() {
            return this.userId;
        }
        
        public void setUserId(Integer userId) {
            this.userId = userId;
        }
    
        public String getUserName() {
            return this.userName;
        }
        
        public void setUserName(String userName) {
            this.userName = userName;
        }
    
        public String getUserPassword() {
            return this.userPassword;
        }
        
        public void setUserPassword(String userPassword) {
            this.userPassword = userPassword;
        }
    
        public String getUserStatus() {
            return this.userStatus;
        }
        
        public void setUserStatus(String userStatus) {
            this.userStatus = userStatus;
        }
    
    }

User.hbm.xml

<?xml version="1.0" encoding="utf-8"?>

Hibernate配置文件

Hibernate.cfg.xml

<?xml version='1.0' encoding='UTF-8'?>
    <!DOCTYPE hibernate-configuration PUBLIC
              "-//Hibernate/Hibernate Configuration DTD 3.0//EN"

Struts 2 配置文件

Struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">

    			<result name="success">/index.jsp</result>
    		</action>
    	</package>
    </struts>

Hibernate配置文件解析类

HibernateSessionFactory.java

package com.sunline.dao;
    
    import org.hibernate.Session;
    import org.hibernate.SessionFactory;
    import org.hibernate.cfg.Configuration;
    
    public class HibernateSessionFactory {
        private SessionFactory sessionFactory;
        public HibernateSessionFactory(){
            
        }
        
        public SessionFactory config(){
            try{
                Configuration configuration= new Configuration();
                Configuration configure=configuration.configure("hibernate.cfg.xml");
                return configure.buildSessionFactory();
            }catch(Exception e){
            e.getMessage();
            return null;
            }
        }
        
        public Session getSession(){
            sessionFactory=config();
            return sessionFactory.openSession();
        }
    }

数据访问层Dao类

UserDao.java

package com.sunline.dao;
    
    import java.util.List;
    
    import org.hibernate.Query;
    import org.hibernate.Session;
    import org.hibernate.Transaction;
    
    import com.sunline.entity.User;
    
    public class UserDao {
    	private Session session;
    	private Transaction transaction;
    	private Query query;
    	HibernateSessionFactory getSession;
        public List<User> Login(String user_name,String user_password){
        	getSession = new HibernateSessionFactory();
        	session = getSession.getSession();
            try{
                String hqlsql="from User as u where u.userName=? and u.userPassword=?";
                query=session.createQuery(hqlsql);
                query.setParameter(0, user_name);
                query.setParameter(1, user_password);
                List<User> list=query.list();
                transaction=session.beginTransaction();
                System.out.println("查询成功!");
                transaction.commit();
                return list;
            }catch(Exception e){
                System.out.println("查询错误!");
                e.printStackTrace();
                return null;
            }
        }
    }

Action控制类

登录控制类:

LoginAction.java

package com.sunline.action;
    
    import java.util.List;
    import java.util.Map;
    
    import com.opensymphony.xwork2.ActionContext;
    import com.opensymphony.xwork2.ActionSupport;
    import com.sunline.dao.UserDao;
    import com.sunline.entity.User;
    
    public class LoginAction extends ActionSupport {
    	private static final long serialVersionUID = 1889710968497585080L;
    	private String user_name ;
    	private String user_password;
    	public String getUser_name() {
    		return user_name;
    	}
    	public void setUser_name(String user_name) {
    		this.user_name = user_name;
    	}
    	public String getUser_password() {
    		return user_password;
    	}
    	public void setUser_password(String user_password) {
    		this.user_password = user_password;
    	}
    	@Override
    	public String execute() throws Exception {
    		// TODO Auto-generated method stub
    		UserDao dao = new UserDao();
    		List<User> list = dao.Login(this.user_name, this.user_password);
    		if(list.size()>=1){
    			ActionContext context = ActionContext.getContext();
    			Map<String, Object> session = context.getSession();
    		//	session.put("user",list);
    			session.put("user",this.user_name);
    			return SUCCESS;
    		}
    		else{
    			return ERROR;
    		}
    	}
    	
    }

注销控制类:

LogoutAction.java

package com.sunline.action;
    
    import java.util.Map;
    
    import com.opensymphony.xwork2.ActionContext;
    import com.opensymphony.xwork2.ActionSupport;
    
    public class LogoutAction extends ActionSupport {
    	private static final long serialVersionUID = 1L;
    
    	@Override
    	public String execute() throws Exception {
    		// TODO Auto-generated method stub
            Map session = ActionContext.getContext().getSession(); 
            session.remove("user"); 
    		return SUCCESS;
    	}
        
    }
