Question

我正在使用JPA存储库。以下是配置：

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

    </beans:bean>
    <beans:bean id="dataSource" class="com.ca.common.CustomDataSource">

        <beans:property name="entityManagerFactory" ref="entityManagerFactory"></beans:property>
    </beans:bean>
</beans:beans>

POM条目：

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-entitymanager</artifactId>
        <version>5.1.1.Final</version>
    </dependency>
<dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-jpa</artifactId>
        <version>1.10.4.RELEASE</version>
    </dependency>

以下是JPA课程：

package com.ca.dao.client;

import java.io.Serializable;

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.JpaSpecificationExecutor;
import org.springframework.stereotype.Repository;

import com.ca.bean.client.ClientBean;

@Repository
public interface ClientDAO  extends JpaRepository<ClientBean, Serializable>, JpaSpecificationExecutor<ClientBean>{

}

以下是我尝试将bean保存到DB中的服务类

package com.ca.service.impl;
import javax.transaction.Transactional;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.ca.dao.client.ClientDAO;

@Service
public class ScheduleTaskServiceImpl implements ScheduleTaskService {

    @Autowired
    private ClientDAO clientDAO;

    @Override
    @Transactional
    public void create(ClientBean cb) {
        clientDAO.save(db);
        throw new RuntimeException("sdfdsf");
    }
}

在上面的服务类中，我在保存详细信息后抛出运行时异常。问题是在抛出运行时异常后，事务没有得到回滚。在DB中仍然会创建条目即使在删除@Transactional之后，我也看到了相同的行为。这意味着即使我将删除@Transactional，它也会保存数据库中的条目。

这里有什么问题？请帮忙。

即使我删除@Transactional

，数据也会插入到数据库中

JpaRepository-数据库操作在没有@Transactional的情况下工作
