             Summary: Configure endpoints with many options in the DSL using a mix of url and properties
                 Key: CAMEL-7419
                 URL: https://issues.apache.org/jira/browse/CAMEL-7419
             Project: Camel
          Issue Type: New Feature
          Components: camel-blueprint, camel-core, camel-spring
            Reporter: Claus Ibsen
             Fix For: 3.0.0


See nabble

We could toy with the idea of allowing to configure endpoints using a mix of uri's and properties. So you can define the uri in a more readable manner if it has many options.

{code}
<from uri="ftp:someserver">
   <property name="delete" value="true"/>
   <property name="username" value="{{ftpUser}}"/>
   <property name="password" value="Se!@rec"/>
   ... // more properties here
</from>
{code}

This should also be supported in the <endpoint>, eg
{code}
<endpoint id="myFtp" uri="ftp:/xxxx">
  <property name="delete" value="true"/>
   <property name="username" value="{{ftpUser}}"/>
   <property name="password" value="Se!@rec"/>
</endpoint>
{code}

We could also support breaking (a bit wacky idea) up the url's in multiple properties url2, url3, url4, which get's appended as one combined url by Camel internally. This allows people to breakup options that may belong together in a few url's. We may come up with a better name than url2, url3 etc.
{code}
<from uri="ftp:someserver">
  <property name="url2" value=".... more options here"/>
  <property name="url3" value=".... more options here"/>
</from>
{code}

Also we can support the p:xxx attribute syntax so you can do shorthand property assignment. We do this with the property placeholder in the EIPs.
(see Using property placeholders for any kind of attribute in the XML DSL at http://camel.apache.org/using-propertyplaceholder.html). Then it becomes just one tag.
{code}
<from uri="ftp:someserver"
   p:delete="true" 
   p:username="{{ftpUser}}"
   p:password="Se!@rec"/>
{code}

Although using the <from><property> is similar to what you do in spring/blueprint and also tooling friendly. So you can have code assistance in your IDE, and XML schema validation. 

Also it allows for people to configure their passwords without using RAW() style. As the value is used as-is.

And for Java DSL, we can have some java builder to do similar. But people can also just break up their strings, or use string format etc.
