如果我在 Oracle 表中有 100 行，我希望收到一封正文中包含 100 行的电子邮件，而不是收到 100 封电子邮件，每行一封……我认为 transactionPerMessage 会做到这一点（工具提示说，“如果false，整个结果集将有一个事务”），但无论我将其设置为 true 还是 false，都没有区别。

让 Mule 像当前一样每行创建一条消息，然后使用聚合器将消息按 100 分组。您还必须在聚合器上为可能不会达到 100 的最后一组配置超时（除非您的记录总是 100 的倍数）。

如果您还在端点上将 transactionPerMessage 属性设置为“true”并添加如下事务，则在连接器上将 transactionPerMessage 设置为“false”应该可以工作：

<jdbc:inbound-endpoint queryKey="GetUnprocessedInvoices" queryTimeout="-1"   pollingFrequency="1000" connector-ref="Database" doc:name="Database">
    <jdbc:query key="GetUnprocessedInvoices" value="SELECT        INVOICE_NUMBER FROM            FIN.LHF_INVOICE_WORKFLOW&#13;&#10;WHERE        (STATUS_FLAG = 'N')"/>
    <jdbc:transaction action="ALWAYS_BEGIN"/>
    <property key="receiveMessageInTransaction" value="true"/>
</jdbc:inbound-endpoint>
