1. 写测试用例
说明：使用spring的原因我可以轻松配置Bean方便进行依赖注入
其中HibernateConfig是bean的配置文件
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes=HibernateConfig.class)
public class TestMessage {
@Autowired
private SessionFactory sessionFactory;
@Test
public void test() {
Session session = sessionFactory.openSession();
org.hibernate.Transaction tx = session.beginTransaction();
Message message = new Message("hello world");
Long msgId = (Long)session.save(message);
tx.commit();
session.close();
}
}
2. 在HibernateConfig中实现dataSource和sessionFactory两个bean
其中@ComponentScan具有自动扫描的功能
@Configuration
@ComponentScan
public class HibernateConfig {
@Bean
public DataSource dataSource(){
BasicDataSource dataSource = new BasicDataSource();
dataSource.setUrl("jdbc:mysql://localhost:3306/shopping");
dataSource.setDriverClassName("com.mysql.jdbc.Driver");
dataSource.setUsername("root");
dataSource.setPassword("");
return dataSource;
}
@Bean
public LocalSessionFactoryBean sessionFactory(DataSource dataSource){//自动关联其他的bean：dataSource
LocalSessionFactoryBean sfb = new LocalSessionFactoryBean();
sfb.setDataSource(dataSource);
sfb.setPackagesToScan(new String[] { "model" });
// sfb.setMappingResources(new String[] { "Spitter.hbm.xml" });
Properties props = new Properties();
props.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQLDialect");
props.setProperty("hibernate.hbm2ddl.auto", "update");
props.setProperty("hibernate.show_sql", "true");
sfb.setHibernateProperties(props);
return sfb;
}
}
其中sessoinFactory的入参，dataSource会自被关联到dataSource，进行注入。
