java - Spring Integration Mail - 将 XML 转换为 Java Config

Question

我是 Spring Framework 的新手，我在将 *.xml 转换为 Java Config 时遇到了一些麻烦。我不知道该如何替换这一行:

<int:channel id="emails"/>

你可以在下面看到我的文件

xml文件:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/integration http://www.springframework.org/schema/integration/spring-integration.xsd

       xmlns:int="http://www.springframework.org/schema/integration"
       xmlns:int-mail="http://www.springframework.org/schema/integration/mail"
       xmlns:util="http://www.springframework.org/schema/util">

    <int:channel id="emails"/>

    <util:properties id="javaMailProperties">
        <prop key="mail.imap.socketFactory.class">javax.net.ssl.SSLSocketFactory</prop>
        <prop key="mail.imap.socketFactory.fallback">false</prop>
        <prop key="mail.store.protocol">imaps</prop>
        <prop key="mail.debug">true</prop>
    </util:properties>

    <int-mail:imap-idle-channel-adapter id="mailAdapter"
                                  store-uri="imaps://login:pass@imap-server:993/INBOX"
                                  java-mail-properties="javaMailProperties"
                                  channel="emails"
                                  should-delete-messages="false"
                                  should-mark-messages-as-read="true">
    </int-mail:imap-idle-channel-adapter>
</beans>

我已经创建的 Java 配置:

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.integration.mail.ImapIdleChannelAdapter;
import org.springframework.integration.mail.ImapMailReceiver;

import java.util.Properties;

@Configuration
class ImapConfiguration {

    private Properties javaMailProperties() {
        Properties javaMailProperties = new Properties();

        javaMailProperties.setProperty("mail.imap.socketFactory.class","javax.net.ssl.SSLSocketFactory");
        javaMailProperties.setProperty("mail.imap.socketFactory.fallback","false");
        javaMailProperties.setProperty("mail.store.protocol","imaps");
        javaMailProperties.setProperty("mail.debug","true");

        return javaMailProperties;
    }

    @Bean
    ImapIdleChannelAdapter mailAdapter() {
        ImapMailReceiver mailReceiver = new ImapMailReceiver("imaps://login:pass@imap-server:993/INBOX");

        mailReceiver.setJavaMailProperties(javaMailProperties());
        mailReceiver.setShouldDeleteMessages(false);
        mailReceiver.setShouldMarkMessagesAsRead(true);

        return new ImapIdleChannelAdapter(mailReceiver);
    }
}

Answer 1

I don't know how should I replace this line:

<int:channel id="emails"/>

刚好

@Bean
public MessageChannel emails() {
    return new DirectChannel();
}

请阅读Reference Manual了解更多信息并查看 samples项目。

是的，不要忘记您的一些@Configuration 类的@EnableIntegration:http://docs.spring.io/spring-integration/reference/html/overview.html#programming-tips
