如何通过骆驼春天DSL发送文件作为邮件附件 [英] How to send file as mail attachment via camel spring DSL

问题描述

我用骆驼2.9.x对我们目前的项目集成的目的。其中一个途径是由两个端点 - 文件查询终端和SMTP邮件端点。由第一端点产生的文件必须通过SMTP端点作为附件发送。

I'm using Camel 2.9.x for integration purposes in our current project. One of the routes consists of two endpoints - file polling endpoint and smtp mail endpoint. Files produced by the first endpoint must be sent through smtp endpoint as attachments.

有关骆驼的配置我们使用Spring DSL（这其实是一个要求）。 Spring版本3.1.1是。不幸的是，我发现只有Java的DSL的例子和骆驼的路线文件附加到电子邮件中的文档。

For Camel configuration we're using Spring DSL (this actually is a requirement). Spring version is 3.1.1. Unfortunately, I've found only java dsl examples and documentation of attaching a file to a e-mail message in camel routes.

<endpoint uri="file:///path/to" id="file-source"/>
<endpoint uri="smtp://mail.example.com:25/?username=[e-mail]&amp;password=secret&amp;to=[e-mail]" id="mail-dest"/>
<route id="simplified-for-readability">
  <from ref="file-source"/>
  <to ref="mail-dest"/>
</route>

此配置文件发送纯/文身上，而不是作为附件（即使二进制文件）。
有没有一种方法来发送文件作为附件，而不使用Java DSL？

This config sends files as plain/text body, not as attachments (even binary files). Is there a way to send files as attachments without using Java dsl?

推荐答案

这可以用Spring配置完成，但是你可能需要codeA简单的java bean左右，虽然不具有弹簧或做java的DSL。

This could be done with Spring config, but you might have to code a simple java bean or so, although that does not have to do with spring or java DSL.

首先创建一个与此相似的类（你可能需要在这里解决的东西）：

First create a class similar to this one (you might need to fix stuff here):

// Note: Content Type - might need treatment!
public class AttachmentAttacher{
   public void process(Exchange exchange){
      Message in = exchange.getIn();
      byte[] file = in.getBody(byte[].class);
      String fileId = in.getHeader("CamelFileName",String.class);
      in.addAttachment(fileId, new DataHandler(file,"plain/text"));
    }
}

然后，只需线了一个Spring bean，并在您的路线中使用它。应该做的伎俩。

Then just wire up a spring bean and use it in your route. Should do the trick.

<bean id="attacher" class="foo.bar.AttachmentAttacher"/>

<route>
  <from ref="file-source"/>
  <bean ref="attacher"/>
  <to ref="mail-dest"/>
</route>
