Java JpaRepository保存方法不使用Derby DB提交

我已经阅读了许多帖子，这些问题列出了确保来自JpaRepository的save方法在数据库中提交记录的附加步骤。在transactionManager上使用代理/使用Transactional with需要_NEW作为传播等，但我仍然无法获得我的用例的确切解决方案。这似乎是一个基本的用例，但这里有些不对劲

ApplicationContext.xml

<context:component-scan base-package="com.oracle.blog" />
 <jpa:repositories base-package="com.oracle.blog.repo" />
 <tx:annotation-driven/>

 <bean id="dataSource"
    class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="org.apache.derby.jdbc.ClientDriver" />
    <property name="url"
        value="jdbc:derby://localhost:1527/MyDerby;create=true" />
    <property name="username" value="root" />
    <property name="password" value="root" />
 </bean>

 <bean id="entityManagerFactory"
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="dataSource" ref="dataSource"></property>
    <property name="packagesToScan" value="com.oracle.blog"/>
    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
            <property name="databasePlatform" value="org.hibernate.dialect.DerbyDialect" />
        </bean>
    </property>
    <property name="jpaProperties">
        <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.DerbyDialect</prop>
            <prop key="hibernate.hbm2ddl.auto">create</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.use_sql_comments">false</prop>
            <!-- <prop key="hbm2ddl.auto">update</prop> -->
        </props>
    </property>

 </bean>
 <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory" />
 </bean>

<bean id="authorDAO" class="com.oracle.blog.repo.AuthorDAO">
</bean>

我从main调用它，从AuthorDAO实例调用save方法。 请指出我可以在主方法/类中使用的任何注释。 我尝试使用

@Commit

（在类级别上）、

@Transactional

（在主方法级别上）

更新 我通过应用程序上下文在main中获得AuthorDAO的bean实例：

AuthorDAO authDAO = (AuthorDAO)context.getBean("authorDAO");
        //authDAO.save(authObj);
        System.out.println(authDAO.save(authObj).getAuthorId());

在下面找到EntityManager日志。日志中没有任何错误。事实上，它正确地列出了要合并的实体。save方法返回实体fine。只是它没有被提交给DB

已解决 确保在将JavaBean列为JPA实体时，在

@table

注释中提到了正确的表名和模式名

是否关闭了数据库？是否可以包含所有代码？我假设您正在主类中创建一个新的AuthorDAO实例。我从main

AuthorDAO authDAO=（AuthorDAO）context.getBean（“AuthorDAO”）中的应用程序上下文获取AuthorDAO的bean实例//save（authObj）；System.out.println（authDAO.save（authObj.getAuthorId（））你关闭数据库了吗？你能包括你所有的代码吗？我假设您正在主类中创建一个新的AuthorDAO实例。我从main
