email - spring 接收没有 xml 的电子邮件(仅使用注释)

Question

我需要定期检查大约 30 个邮箱，并且只想使用注释来完成此操作。我知道如何处理 XML 文件，它看起来像这样:

<mail:inbound-channel-adapter id="ImapAdapter"
                              store-uri="imaps://${login}:${pass}@${host}:993/inbox"
                              channel="testReceiveEmailChannel"
                              should-delete-messages="false"
                              should-mark-messages-as-read="true"
                              auto-startup="true"
                              java-mail-properties="javaMailProperties">
    <int:poller fixed-delay="200"
                time-unit="SECONDS"
                task-executor="asyncTaskExecutor"/>
</mail:inbound-channel-adapter>

<int:channel id="testReceiveEmailChannel">
    <int:interceptors>
        <int:wire-tap channel="logger"/>
    </int:interceptors>
</int:channel>

<int:service-activator input-channel="testReceiveEmailChannel"
                       ref="testMailReceiverService"
                       method="receive"/>

<bean id="testMailReceiverService" class="com.myproject.email.EmailReceiverService">
    <property name="mailBox" value="${login}"/>
</bean>


<int:logging-channel-adapter id="logger" level="DEBUG"/>

我知道 Spring 4+ 有 @InboundChannelAdapter 但我不知道如何使用它。其实我是 Spring 的新人，所以非常感谢任何帮助!

您正在研究正确的方法 - @InboundChannelAdapter。如果你看一下 Documentation正确的，你会看到这样的东西:

@Bean
@InboundChannelAdapter(value = "testReceiveEmailChannel", poller = @Poller(fixedDelay = "200000", taskExecutor = "asyncTaskExecutor"))
public MessageSource<javax.mail.Message> mailMessageSource(MailReceiver mailReceiver) {
    MailReceivingMessageSource mailReceivingMessageSource = new MailReceivingMessageSource(mailReceiver);
    // other setters here
    return mailReceivingMessageSource;
}

MailReceiver 是这样的:

@Bean
public MailReceiver imapMailReceiver(@Value("imaps://${login}:${pass}@${host}:993/inbox") storeUrl) {
     ImapMailReceiver imapMailReceiver = new ImapMailReceiver(storeUrl);
        // other setters here
     return imapMailReceiver;
}

还有用于 MessageChannel 的其他 @Bean 和用于您的 EmailReceiverService 的 @ServiceActivator。

考虑将 Spring Integration Java DSL 作为 Java 配置工具.
