Hibernate使用JUnit进行测试

一 Junit常用注解

@Test：测试方法

@Before：初始化方法

@After：释放资源

二创建测试类StudentsTest

三通过Hibernate API编写访问数据库的代码骨架

四测试代码

import java.util.Date;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
//测试类
public class StudentsTest {
        
        private SessionFactory sessionFactory;
        private Session session;
        private Transaction transaction;
        @Before
        public void init(){
            // 创建配置对象  
            Configuration config = new Configuration().configure();
            //config.addClass(Students.class);
            // 创建服务注册对象
            ServiceRegistry serviceRegistery = new ServiceRegistryBuilder().applySettings(config.getProperties()).buildServiceRegistry();
            // 创建会话工厂对象
            sessionFactory = config.buildSessionFactory(serviceRegistery);
            // 创建会话对象
            session = sessionFactory.openSession();
            // 开启事务
            transaction = session.beginTransaction();
        }
        
        @After
        public void destory(){
            // 提交事务
            transaction.commit();
            // 关闭会话
            session.close();
            // 关闭会话工厂
            sessionFactory.close();
        }
        
        @Test
        public void testSaveStudents(){
                Students s= new Students(1,"张三丰","男",new Date(),"武当山");
            session.save(s);
        }
}

五测试输出

Hibernate:

drop table if exists STUDENTS

Hibernate:

create table STUDENTS (

SID integer not null,

SNAME varchar(255),

GENDER varchar(255),

BIRTHDAY datetime,

ADDRESS varchar(255),

primary key (SID)

)

九月 17, 2017 3:31:29 下午 org.hibernate.tool.hbm2ddl.SchemaExport execute

INFO: HHH000230: Schema export complete

Hibernate:

insert

into

STUDENTS

(SNAME, GENDER, BIRTHDAY, ADDRESS, SID)

values

(?, ?, ?, ?, ?)

六测试结果
