------------------------------------
Summary: Quartz Endpoint with a SimpleTrigger does not support
referencing a bean in URI
Key: CAMEL-7540
URL: https://issues.apache.org/jira/browse/CAMEL-7540
Project: Camel
Issue Type: Bug
Components: camel-quartz
Affects Versions: 2.12.3
Reporter: Nathan Jensen
Priority: Minor
When configuring a Quartz endpoint with Spring, if you are using a
SimpleTrigger then it doesn't work to use a bean reference as a parameter on
the URI. For example,
{code:xml}
<bean id="taskCount" class="java.lang.Integer">
<constructor-arg>5</constructor-arg>
</bean>
<endpoint id="taskLauncher"
uri="quartz://taskThread?trigger.repeatCount=#taskCount"/>
{code}
Since there is no cron specified, it will use a SimpleTrigger. In
QuartzComponent.createEndpoint(String, String, Map) it will get the repeatCount
as the string "#taskCount" instead of the actual bean, and therefore when it
goes to convert it to an Integer, it will fail with an exception like this:

Caused by: org.apache.camel.TypeConversionException: Error during type
conversion from type: java.lang.String to the required type: java.lang.Integer
with value #taskCount due java.lang.NumberFormatException: For input string:

A workaround is to explicitly set the value of repeatCount or use a system or
environment variable, but there are situations where we want to use a value
defined elsewhere in the application context. Looking at the code, it appears
a similar problem will occur with repeatInterval.
