-----------------------------------------------
Summary: camel-main - Unable to declare map bean with dotted keys
Key: CAMEL-18700
URL: https://issues.apache.org/jira/browse/CAMEL-18700
Project: Camel
Issue Type: Bug
Components: camel-bean, camel-main
Affects Versions: 3.19.0, 3.18.1
Reporter: Christian Schubert-Huff
I have been trying to configure camel-ldap using camel-main:
|*dirContextName* (producer)|*Required* Name of either a
javax.naming.directory.DirContext, or java.util.Hashtable, or Map bean to
lookup in the registry. If the bean is either a Hashtable or Map then a new
javax.naming.directory.DirContext instance is created for each use.|
It should be sufficient to declare a map bean like this:
{code:java}
camel.beans.ldapserver[java.naming.provider.url] = ldaps://ldap.local:636
camel.beans.ldapserver[java.naming.security.principal] = scott
camel.beans.ldapserver[java.naming.security.credentials] = tiger
{code}
However, this fails:
{noformat}
java.lang.IllegalArgumentException: Cannot find getter method: java on bean:
class java.util.LinkedHashMap when binding property: java.naming.provider.url

{noformat}
Note that the keys are - required - to be dotted, as they are known constants
declared in {{javax.naming.Context}}
Reproduction is easy:
{code:java}
@Test
public void testBindBeansMapSquareDotted() {
Main main = new Main();
main.configure().addRoutesBuilder(new MyRouteBuilder());
// create by class
main.addProperty("camel.beans.ldapserver[java.naming.provider.url]",
"ldaps://ldap.local:636");
main.addProperty("camel.beans.ldapserver[java.naming.security.principal]",
"scott");
main.addProperty("camel.beans.ldapserver[java.naming.security.credentials]",
"tiger");
main.start();
CamelContext camelContext = main.getCamelContext();
assertNotNull(camelContext);
Map foo = camelContext.getRegistry().lookupByNameAndType("ldapserver",
Map.class);
assertNotNull(foo);
assertEquals(3, foo.size());
assertEquals("ldaps://ldap.local:636",
foo.get(javax.naming.Context.PROVIDER_URL));
assertEquals("scott", foo.get(javax.naming.Context.SECURITY_PRINCIPAL));
assertEquals("tiger",
foo.get(javax.naming.Context.SECURITY_CREDENTIALS));
main.stop();
}
{code}
There is a workaround, which requires the declaration of an additional property
for each entry, like this:
{noformat}
providerUrl = java.naming.provider.url
camel.beans.ldapserver[{{providerUrl}}] = ldaps://ldap.local:636
{noformat}
This affects both version 3.18.1 and the latest snapshot from main.
