Question

我正在尝试使用apache Camel和xml来获取邮件。请教我如何编写xml。

※我只想用xml检查新邮件。邮件移到新邮件后。

我通过telnet发送到邮件
我检查了邮箱（新目录（Maildir））中的邮件
我写了xml。（您可以在下面查看）
我部署了jar文件，并且发生了错误。（您可以在下面查看）

・ XML

<?xml version="1.0" encoding="UTF-8"?>
<blueprint
  xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="
    http://www.osgi.org/xmlns/blueprint/v1.0.0
    https://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd">
  <camelContext xmlns="http://camel.apache.org/schema/blueprint">
  <route trace="true">
          <to uri="pop3://ipaddress?to=user@domain&amp;username=user@domain&amp;password=user&amp;unseen=true" />
  </route>
  </camelContext>
</blueprint>

谢谢 ====================================== >

我固定了代码。我在下面每隔1分钟收到一次servicemix.log。我检查邮件（新目录）移动到当前目录。但是我无法在servicemix.log上检查telnet DATA的内容我期望以下行为

【问题】当我添加以下代码时，为什么没有错误？

<log message="received the message with xml" />

・代码

・期待行为

部署jar文件并移动时没有错误 / opt / serviecmix / deploy目录。
检查servicemix.log并仅查找新目录的新内容文件（邮件）
检查cur目录并查找从新目录移出的邮件。

谢谢

================================================ -

我已修复并检查是否在servicemix.log上收到邮件我有一个新问题。

【问题】・我想用“ to”标记下面的代码。但是它无法读取“新目录（文件）”，也无法在servicemix.log上写入日志消息。我可以像下面那样将端点写到“ to”标签吗？

<route id="email-consumer-entrypoint-route" trace="true">
 <from uri="direct:start" />
 <log message="received the message with xml" />
 <to uri="imap://ipaddress?to=user@domain&amp;username=user@domain&amp;password=user&amp;unseen=true&amp;consumer.delay=60000&amp;mapMailMessage=false&amp;fetchSize=1" />

谢谢 ====================================== >

非常感谢您。我有新问题。

【问题】

我想只使用一次mailapi来使用sheduler（例如 quartz2组件）。（想要指定时间）我正在尝试使用 crystal2组件，但由于无效代码而没有移动。您可以请参阅下面的代码。我应该怎么写？
我不使用“ consumer.delay”参数，如何停止该功能？

・错误

 - 2.16.4 | Error occurred during starting Camel: CamelContext(camel-2) due CronExpression '0 0/5 * * * ?@domain' is invalid.
java.lang.RuntimeException: CronExpression '0 0/5 * * * ?@domain' is invalid.

谢谢

Answer 1

当您说“带有XML的Apache Camel”时，我想您的意思是说是Spring DSL。

另一件事是，要使用骆驼接收电子邮件，您将需要使用骆驼邮件组件。就像收到一封电子邮件-

<route id="email-consumer-entrypoint-route">
            <from uri="imaps://imap.gmail.com?username=username@gmail.com&password=p@ssword&delete=false&unseen=true&consumer.delay=60000&mapMailMessage=false&fetchSize=1" />
