回滾在@Transactional注釋服務中不起作用。春季 休眠

在我的代碼中，服務方法 savePerson 用@Transactional 進行了注釋。在這個方法中，一個 Person 物體被持久化，并且立即故意拋出一個運行時例外。我認為不應提交事務，但 Person 物體保留在資料庫中....回滾不起作用，我不知道為什么。

這是我的休眠配置：

package newp;

import java.util.Properties;

import javax.sql.DataSource;

import org.apache.commons.dbcp.BasicDataSource;
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;

@Configuration
@EnableTransactionManagement
public class HibernateConf {

    @Bean
    public LocalSessionFactoryBean sessionFactory() {
        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
        sessionFactory.setDataSource(dataSource());
        sessionFactory.setPackagesToScan(new String[]{"newp"});
        sessionFactory.setHibernateProperties(hibernateProperties());

        return sessionFactory;
    }

    @Bean
    public DataSource dataSource() {
        BasicDataSource dataSource = new BasicDataSource();
        dataSource.setDriverClassName("com.mysql.cj.jdbc.Driver");
        dataSource.setUrl("jdbc:mysql://localhost:3306/poas");
        dataSource.setUsername("admin");
        dataSource.setPassword("admin");

        return dataSource;
    }

    @Bean
    public PlatformTransactionManager hibernateTransactionManager() {
        HibernateTransactionManager transactionManager= new HibernateTransactionManager();
        transactionManager.setSessionFactory(sessionFactory().getObject());
        return transactionManager;
    }

    private final Properties hibernateProperties() {
        Properties hibernateProperties = new Properties();
        
        hibernateProperties.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQL5Dialect");
        hibernateProperties.setProperty("hibernate.show_sql", "true");

        return hibernateProperties;
    }   
}

這是我的服務：

package newp.services;

import javax.transaction.Transactional;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.EnableTransactionManagement;

import newp.dao.PersonDao;
import newp.model.Person;

@Service
public class PersonService{
    @Autowired
    PersonDao dao;
    
    @Transactional
    public void savePerson(Person p) {
        dao.savePerson(p);          
        throw new RuntimeException();
    }
    
}

DAO

package newp.dao;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import newp.entities.PersonEntity;
import newp.model.Person;

@Repository 
public class PersonDao {
    @Autowired
    SessionFactory sessionFactory;
    
    public void savePerson(Person person) {
        Session s = sessionFactory.getCurrentSession();
        PersonEntity p=new PersonEntity();
        p.setAge(person.getAge());      
        p.setName(person.getName());
        p.setSurname(person.getSurname());
        s.saveOrUpdate(p);
    }   

}
