I'm new to camel ... Trying to send a multipart/alternative (text/plain and
text/html) using Spring, Camel, and Velocity.
In my route I have the following snippet:
<setHeader headerName="alternativeBodyHeader">
<method bean="eDeliveryProcessor"
method="plainTemplateAsString"/>
</setHeader>
<to uri="velocity://email-html.vm" />
<to ref="smtpServer" />
My bean is autowired and the method looks like this:
@Handler
public String plainTemplateAsString(Exchange exchange,
@Headers Map<String, Object> headers,
@Header("edeliveryId") String
edeliveryId,
@Body DeliveryRequest request) throws AddressException {
VelocityEngine ve = new VelocityEngine();
ve.setProperty(RuntimeConstants.RESOURCE_LOADER, "classpath");
ve.setProperty("classpath.resource.loader.class",
ClasspathResourceLoader.class.getName());
ve.init();
Template template = ve.getTemplate("email-plain.vm");
Context context = new VelocityContext();
context.put("dateTool", new DateTool());
Email email = (Email) request.getType();
//context.put("body.type.body", email.getBody());
//context.put("body.id", edeliveryId);
context.put("greeting", "hello");
context.put("person", "John Doe");
StringWriter stringWriter = new StringWriter();
template.merge(context, stringWriter);
exchange.getIn().setHeader(Exchange.CONTENT_TYPE, "text/html");
exchange.getIn().setHeader("alternativeBodyHeader",
stringWriter.toString());
System.out.println(stringWriter.toString());
return stringWriter.toString();
}
I have 2 templates.
email-html.vm:
<html>
<body>
<div><em>
${greeting} This is a system generated email. Please do not
reply to this email.
</em></div>
</body>
</html>
email-plain.vm:
${greeting} ${person} This is a system generated email. Please do not
reply to this email.
I setup Outlook 2007 to receive plain text. When the code runs I receive
email-html.vm converted to plain text. I was expecting the content of
email-plain.vm version instead.
Advice would be much appreciated! Thanks.
