如何将 buyItems 中的产品字段加入到产品集合中，该购买项目是一个嵌入式数组文档。我需要这样的东西。

  "purchaseItems": [
    {
      "product": {

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.
