采用最新的SSH配置需要配置log，避免输出警告

log4j.properties

<?xml version="1.0" encoding="UTF-8"?>
log4j.rootLogger=WARN, stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m%n

log4j2.xml

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

<Configuration status="warn">
    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%m%n" />
        </Console>
    </Appenders>
    <Loggers>
        <Root level="INFO">
            <AppenderRef ref="Console" />
        </Root>
    </Loggers>
</Configuration>

在环境搭建完成以后编写测试文件

package test;

import org.hibernate.SessionFactory;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class testdemo {
    @SuppressWarnings("resource")
    public static void main(String[] args) {
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("ApplicationContext.xml");
        SessionFactory bean = (SessionFactory) context.getBean("mysessionFactory");
        System.out.println(bean);
    }
}

进行项目分层

实体User

// default package

package ssh.entity;
import java.util.Date;

/**

public class User implements java.io.Serializable {

    /**
     *

    private static final long serialVersionUID = 1L;
    private Integer id;
    private String password;
    private Integer qqnumber;
    private String username;
    private Date time;

    public User() {
    }

    public User(String password, Integer qqnumber, String username, Date time) {
        this.password = password;
        this.qqnumber = qqnumber;
        this.username = username;
        this.time = time;
    }

    @Override
    public String toString() {
        return "User [id=" + id + ", password=" + password + ", qqnumber="
                + qqnumber + ", username=" + username + ", time=" + time + "]";
    }

    public Integer getId() {
        return this.id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getPassword() {
        return this.password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public Integer getQqnumber() {
        return this.qqnumber;
    }

    public void setQqnumber(Integer qqnumber) {
        this.qqnumber = qqnumber;
    }

    public String getUsername() {
        return this.username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public Date getTime() {
        return this.time;
    }

    public void setTime(Date time) {
        this.time = time;
    }

}

实体映射

            <column length="10" name="time" />
        </property>
    </class>
</hibernate-mapping>

DAO层实现类

package ssh.daoimpl;

import java.util.List;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.transaction.annotation.Transactional;

import ssh.dao.UserDao;
import ssh.entity.User;

//创建IndexDaoImpl(实现类)实现IndexDao接口
@Transactional
public class UserDaoimpl implements UserDao {

    // 在SSH的设计理念：要使用某个实例，那么就定义声明一个对象，然后
    // 给它添加set方法（用于spring注入进来）
    // 实现不要关注这个实例来自于那里，以及怎么创建，或者它是谁
    private SessionFactory sessionFactory;

    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }

    @SuppressWarnings("deprecation")
    @Override
    public List<User> getAllUser() {
        // sessionFactory这个实例可以自己按常规的hibernate传统写法创建
        // 也可以交给spring去托管
        /*
         * onfiguration cfg = new Configuration().configure(); sessionFactory =
         * cfg.buildSessionFactory();
         */
        // 获取session
        Session session = sessionFactory.getCurrentSession();
        // 后面当使用JPA的时候，EntityManager 类似于 Session
        List<User> list = session.createQuery("from User").list();
        for (User user : list) {
            System.out.println(user.toString());
        }
        
        return list;
    }

}

Sevices实现类

package ssh.serviceimpl;

import java.util.List;

import ssh.dao.UserDao;
import ssh.entity.User;
import ssh.service.IndexService;

//创建IndexServiceImpl(实现类)实现IndexService接口
public class IndexServiceImpl implements IndexService {

    // dao实例使用注入方式
    private UserDao dao;

    // 用于注入使用
    public void setDao(UserDao dao) {
        this.dao = dao;
    }
    // 本类应该编写业务逻辑的代码，
    // 但本例没有业务逻辑，就不用写。
    // 访问数据库的代码，不会出现在service这一层
    // 交给dao来操作数据库

    @Override
    public List<User> getAllUser() {
        // 进行其它的业务逻辑操作，比如增加多一个选项，是否过期
        // 本例不需要
        // ....
        List<User> list = dao.getAllUser();
        return list;
    }

}

Action 实现类这里采用的spring来管理的action的实例，主要可以进行aop加强操作

package action;

import java.util.List;

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

import ssh.entity.User;
import ssh.service.IndexService;

public class registerAction extends ActionSupport{
    //声明service，但不给它创建具体的实现类的实例，
    private IndexService indexService;
     //添加set()方法
    public void setIndexService(IndexService indexService) {
        this.indexService = indexService;
    }

    /**
     * //编写execute()方法
     */
    private static final long serialVersionUID = 1L;

    @Override
    public String execute() throws Exception {
        List<User> list = indexService.getAllUser();
        ActionContext context = ActionContext.getContext();
        context.put("userlist", list);
        return ActionSupport.SUCCESS;
    }
    
    

}
