Spring Boot 和 Hibernate 的简单整合

import org.hibernate.SessionFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.orm.hibernate5.HibernateTransactionManager;
import org.springframework.orm.hibernate5.LocalSessionFactoryBean;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.annotation.EnableTransactionManagement;
 
import javax.sql.DataSource;
import java.util.Properties;
 
@Configuration
@EnableTransactionManagement
public class HibernateConfig {
 
    @Bean
    public LocalSessionFactoryBean sessionFactory(DataSource dataSource) {
        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
        sessionFactory.setDataSource(dataSource);
        sessionFactory.setPackagesToScan("com.example.domain");
        sessionFactory.setHibernateProperties(hibernateProperties());
        return sessionFactory;
    }
 
    @Bean
    public Properties hibernateProperties() {
        Properties properties = new Properties();
        properties.put("hibernate.dialect", "org.hibernate.dialect.MySQL5Dialect");
        properties.put("hibernate.show_sql", "true");
        properties.put("hibernate.format_sql", "true");
        return properties;
    }
 
    @Bean
    @Autowired
    public PlatformTransactionManager hibernateTransactionManager(SessionFactory sessionFactory) {
        HibernateTransactionManager transactionManager = new HibernateTransactionManager();
        transactionManager.setSessionFactory(sessionFactory);
        return transactionManager;
    }
}

这段代码定义了一个配置类，用于创建LocalSessionFactoryBean和HibernateTransactionManager。LocalSessionFactoryBean用于创建SessionFactory，它需要数据源和实体类的包路径。HibernateTransactionManager用于管理事务，它需要SessionFactory作为参数。这段代码提供了Spring Boot和Hibernate整合的基本框架。
