[Discuss] - Camel Properties Component - Change tokens to avoid clash with Spring 3.0
Hi See ticket https://issues.apache.org/activemq/browse/CAMEL-2599 The problem is that Spring 3.0 includes a EL by default which is automatic in use in the Spring XML files. It uses the same tokens as we do with Camel Properties component and therefore Spring EL fails with an exception. The easiest and also least problematic resolution is to use a different tokens in Camel to avoid the clash. It will also be least surprise by Camel end users if they mix and match between Spring EL and Camel Properties. So what tokens do you want to use? Currently we did use - prefix = #{ - suffix = } For example: from(#{cool.start}) .to(log:#{cool.start}?showBodyType=falseshowExchangeId=#{cool.showid}) .to(mock:#{cool.result}); A) === I am thinking of changing to: - prefix = #[ - suffix = ] For example: from(#[cool.start]) .to(log:#[cool.start]?showBodyType=falseshowExchangeId=#[cool.showid]) .to(mock:#[cool.result]); B) === Or maybe? - prefix = #p{ - suffix = } For example: from(#p{cool.start}) .to(log:#p{cool.start}?showBodyType=falseshowExchangeId=#p{cool.showid}) .to(mock:#p{cool.result}); C) We cannot do this one - prefix = ${ - suffix = } As it will clash with Camel Simple language (would take more work to let them co-exist in peace :) However we could most likely use a longer preifx such as - prefix = ${p: - suffix = } For example: from(${p:cool.start}) .to(log:${p:cool.start}?showBodyType=falseshowExchangeId=$p{p:cool.showid}) .to(mock:${p:cool.result}); Do you have any thoughts and preference what tokens to use? -- Claus Ibsen Apache Camel Committer Author of Camel in Action: http://www.manning.com/ibsen/ Open Source Integration: http://fusesource.com Blog: http://davsclaus.blogspot.com/ Twitter: http://twitter.com/davsclaus

What about - prefix = {{ - suffix = }} Then we'd avoid reserved URI characters such as $, #, ... etc. Am 02.04.2010 11:07, schrieb Claus Ibsen: Hi See ticket https://issues.apache.org/activemq/browse/CAMEL-2599 The problem is that Spring 3.0 includes a EL by default which is automatic in use in the Spring XML files.

+1 for #[], or #p{}. The other options still make the Spring EL confused.

Its possible but there is a resolver in DefaultCamelContext which depends on knowing the tokens beforehand. It would be more correct to let the tokens be customizable on PropertiesComponent. But for now they are fixed. I have implemented the suggestion by Martin Krasser to use {{key}} The camel source code now works with both Spring 2.5 and 3.0.

No. Spring EL is an expression language and not a property placeholder mechanism. However there is a ticket in JIRA to add Spring EL as a Language to Camel. Then you can use Spring EL in Camel predicates/expressions etc. Greetings Christian Am 02.04.2010 11:07, schrieb Claus Ibsen: Hi See ticket https://issues.apache.org/activemq/browse/CAMEL-2599 The problem is that Spring 3.0 includes a EL by default which is automatic in use in the Spring XML files.
