[jira] [Created] (CAMEL-7429) Camel Properties Component
concatenation issue
Andrea Cosentino created CAMEL-7429:
---------------------------------------
Summary: Camel Properties Component concatenation issue
Key: CAMEL-7429
URL: https://issues.apache.org/jira/browse/CAMEL-7429
Project: Camel
Issue Type: Bug
Components: camel-core
Affects Versions: 2.12.3
Environment: Linux Ubuntu 13.10, Windows 7
Reporter: Andrea Cosentino
Hi,
Suppose you have a properties file of this type
{code}
#PROPERTIES CONCATENATION
prop1=file:
prop2=dirname
concat.property={{prop1}}{{prop2}}
#PROPERTIES WITHOUT CONCATENATION
property.complete=file:dirname
{code}
and you want to use the property concat.property. Using Camel 2.10.3 loading this property doesn't create any kind of problem. When I upgrade to Camel 2.12.3 I get an exception, that you can reproduce with the following informations.
In *DefaultPropertiesParser* class of org.apache.camel.component.properties package, I found a strange behaviour relative to that specific kind of property. When I execute a test like the following, (the first try to use concatenated property and the second try to use property without concatenation):
{code:title=PropertiesComponentConcatenatePropertiesTest.java}
import org.apache.camel.CamelContext;
import org.apache.camel.ContextTestSupport;
import org.apache.camel.builder.RouteBuilder;
public class PropertiesComponentConcatenatePropertiesTest extends ContextTestSupport {
@Override
protected CamelContext createCamelContext() throws Exception {
CamelContext context = super.createCamelContext();
context.addComponent("properties", new PropertiesComponent("classpath:org/apache/camel/component/properties/concatenation.properties"));
return context;
}
@Override
protected void setUp() throws Exception {
System.setProperty("environment", "junit");
super.setUp();
}
@Override
protected void tearDown() throws Exception {
System.clearProperty("environment");
super.tearDown();
}
public void testConcatPropertiesComponentDefault() throws Exception {
context.addRoutes(new RouteBuilder() {
@Override
public void configure() throws Exception {
from("direct:start").setBody(simple("${properties:concat.property}"))
.to("mock:result");
}
});
context.start();
getMockEndpoint("mock:result").expectedBodiesReceived("file:dirname");
template.sendBody("direct:start", "Test");
assertMockEndpointsSatisfied();
}
public void testWithoutConcatPropertiesComponentDefault() throws Exception {
context.addRoutes(new RouteBuilder() {
@Override
public void configure() throws Exception {
from("direct:start").setBody(simple("${properties:property.complete}"))
.to("mock:result");
}
});
context.start();
getMockEndpoint("mock:result").expectedBodiesReceived("file:dirname");
template.sendBody("direct:start", "Test");
assertMockEndpointsSatisfied();
}
}
{code}
The first test return the following exception:
{code}

{code}
It seems that *DefaultPropertiesParser* don't like concatenation of properties. I've forked Camel project on GitHub and I've added the unit test posted above. Here is the link: https://github.com/ancosen/camel
Investigating the history of the particular class I found that the problem should arise from:
*CAMEL-5328 supports resolution of nested properties in PropertiesComponent*
Here is the link of the commit:
https://github.com/apache/camel/commit/83f4b0f485521967d05de4e65025c4558a75ff3c
Thanks.
Bye
