java - 如何使用 XML 配置设置 IMAP 邮件接收 channel 的取消空闲间隔属性

Question

我正在尝试设置 imap 空闲接收 channel 的 setCancelIdleInterval 属性。我正在使用基于 xml 的配置。这是必需的，因为此处报告了问题:“Spring Integration Mail Google IMAP how to set the frequency of checking the inbox ”。

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(protocol)(IMAP、POP3)支持的所有属性的列表，但找不到任何此类文档。如果能制定这样一个文件，那将会非常有帮助。

下面是 imap-idle channel 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；你必须使用 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 .
