如何使用 XML 配置设置 IMAP 邮件接收通道的 Cancel-Idle-Interval 属性

Question

我正在尝试设置 imap 空闲接收通道的 setCancelIdleInterval 属性。我正在使用基于 xml 的配置。由于此处报告的问题：“Spring Integration Mail Google IMAP how to set the frequency of checking the inbox”，因此需要这样做。

给出的解决方案是针对 Java DSL 配置的，当我尝试在 xml 中实现它时，出现了错误。

我再次阅读了 Spring Integration 文档并尝试获取每个接收协议（IMAP、POP3）支持的所有属性的列表，但找不到任何此类文档。如果可以制作这样的文件，那将是非常有帮助的。

下面是 imap-idle 通道代码，它根据 cancel-idle-interval 属性生成错误。

<int-mail:imap-idle-channel-adapter id="customAdapter"
        store-uri="imap://[username]:[password]@[domain]:993/INBOX"
        channel="receiveChannel"
        auto-startup="true"
        should-delete-messages="false"
        should-mark-messages-as-read="false"
        cancel-idle-interval=1740
        java-mail-properties="javaMailProperties"/>

这是我尝试执行项目构建时收到的错误消息：

Answer 1

cancelIdleInterval 目前无法使用 XML 进行配置；您必须使用JavaConfig 连接bean 或使用简单的<bean/> 配置而不是int-mail: 命名空间。

<bean id="receiver" class="org.springframework.integration.mail.ImapMailReceiver">
     <property name="cancelIdleInterval" value="30" />
     ... other properties.
</bean>

<bean id="adapter" class="org.springframework.integration.mail.ImapIdleChannelAdapter">
    <constructor-arg ref="receiver" />
    ... other properties (outputChannel etc).
</bean>

我打开了an issue to add it to the int-mail namespace。
