三大框架-ssh整合（二）

spring整合hibernate--没有产生hibernate.cfg.xml文件，而是将其中的内容放在了applicationContext.xml中

applicationContext.xml文件内容如下：

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

    </aop:config>
    

</beans>

下面是domain类，UserDao类，UserService类，以及测试类的实现代码
首先User类也即bean先省略；

UserDao类如下所示：

import com.itheima.domain.User;

public interface UserDao {
    public void save(User user);

}

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import com.itheima.domain.User;

// 底层需要SessionFactory，自动创建HibernateTemplate模板
public class UserDaoImpl extends HibernateDaoSupport implements UserDao {

    @Override
    public void save(User user) {
        this.getHibernateTemplate().save(user);
    }

}

UserService类

import com.itheima.domain.User;

public interface UserService {
    public void register(User user);
}

import com.itheima.UserDao.UserDao;
import com.itheima.domain.User;

public class UserServiceImpl implements UserService {

    private UserDao userDao;
    public void setUserDao(UserDao userDao) {
        this.userDao = userDao;
    }
    @Override
    public void register(User user) {
        // TODO Auto-generated method stub
        userDao.save(user);
    }

}

测试类：

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.itheima.UserService.UserService;
import com.itheima.domain.User;


@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:applicationContext.xml")
public class TestApp {
    
    @Autowired
    private UserService userService;
    
    @Test
    public void demo01(){
        User user = new User();
        user.setUsername("jack");
        user.setPassword("1234");
        user.setAge(18);
        
        userService.register(user);
    }
}

注：之前导入的39个.jar文件需要导入进去，同时需要创建一个和user类属性相同的t_user表

CREATE TABLE t_user(
  id INT PRIMARY KEY AUTO_INCREMENT,
  username VARCHAR(50),
  PASSWORD VARCHAR(32),
  age INT 
);

准备工作准备完成即可进行测试。
