春季启动@Transactional

Question

spring boot会自动在控制器层添加@Transactional注释吗？我尝试将@Transactional放在服务层,但似乎控制器层覆盖了注释.

我有这个配置

<tx:advice id="txAdvice" transaction-manager="transactionManager">
    <tx:attributes>
        <tx:method name="find*" read-only="true" isolation="READ_COMMITTED"
            propagation="NOT_SUPPORTED" />
        <tx:method name="load*" read-only="true" isolation="READ_COMMITTED"
            propagation="NOT_SUPPORTED" />
        <tx:method name="get*" read-only="true" isolation="READ_COMMITTED"
            propagation="NOT_SUPPORTED" />
        <tx:method name="*" timeout="30" propagation="REQUIRED" />
    </tx:attributes>
</tx:advice>

<aop:config proxy-target-class="true">
    <aop:advisor advice-ref="txAdvice"
        pointcut="execution(* *..service.*Service*.*(..))" order="1" />
</aop:config>

甚至如果我删除该配置,交易仍然有效.

编辑:

这是我的数据源配置

<bean id="msDataSource" class="org.apache.tomcat.jdbc.pool.DataSource"
    destroy-method="close">
    <property name="driverClassName" value="${jdbc.main.driverClass}" />
    <property name="url" value="${jdbc.main.url}" />
    <property name="username" value="${jdbc.main.username}" />
    <property name="password" value="${jdbc.main.password}" />

</bean>


<bean id="msPUM"
    class="org.springframework.orm.jpa.persistenceunit.DefaultPersistenceUnitManager">
    <property name="defaultDataSource" ref="msDataSource" />
</bean>

<bean id="entityManagerFactory"
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="persistenceUnitManager" ref="msPUM" />
    <!--<property name="jpaVendorAdapter"> <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"> 
        <property name="database" value="ORACLE"/> <property name="generateDdl" value="false"/> 
        <property name="showSql" value="true" /> </bean> </property> -->
</bean>

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

我只是猜测,但我想你在这里要问的是为什么你能够在控制器内的实体上加载惰性集合？

Spring Boot使用默认值"true"配置以下应用程序属性spring.jpa.open-in-view.基本上,这会为整个请求打开一个会话,允许您在@Transactional之外执行上述操作.

将其添加到您的application.properties将关闭它:

spring.jpa.open式视=假
