Additional Camel Quarkus configuration
Simple language
Using the OGNL notation
When using the OGNL notation from the simple language, the camel-quarkus-bean extension should be used.
For instance, the simple expression below is accessing the getAddress() method on the message body of type Client.
---
simple("${body.address}")
---In such a situation, one should take an additional dependency on the camel-quarkus-bean extension as described here. Note that in native mode, some classes may need to be registered for reflection. In the example above, the Client class needs to be registered for reflection.
Using dynamic type resolution in native mode
When dynamically resolving a type from simple expressions like:
-
simple("${mandatoryBodyAs(TYPE)}") -
simple("${type:package.Enum.CONSTANT}") -
from("…").split(bodyAs(TYPE.class)) -
simple("${body} is TYPE")
It may be needed to register some classes for reflection manually.
For instance, the simple expression below is dynamically resolving the type java.nio.ByteBuffer at runtime:
---
simple("${body} is 'java.nio.ByteBuffer'")
---As such, the class java.nio.ByteBuffer needs to be registered for reflection.
Using the simple language with classpath resources in native mode
If your route is supposed to load a Simple script from classpath, like in the following example
from("direct:start").transform().simple("resource:classpath:mysimple.txt");then you need to use Quarkus quarkus.native.resources.includes property to include the resource in the native executable as demonstrated below:
quarkus.native.resources.includes = mysimple.txtMore information about selecting resources for inclusion in the native executable can be found at Embedding resource in native executable.
Configuring a custom bean via properties in native mode
When specifying a custom bean via properties in native mode with configuration like #class:* or #type:*, it may be needed to register some classes for reflection manually.
For instance, the custom bean definition below involves the use of reflection for bean instantiation and setter invocation:
---
camel.beans.customBeanWithSetterInjection = #class:org.example.PropertiesCustomBeanWithSetterInjection
camel.beans.customBeanWithSetterInjection.counter = 123
---As such, the class PropertiesCustomBeanWithSetterInjection needs to be registered for reflection, note that field access could be omitted in this case.

Used for exclusive filtering scanning of RouteBuilder classes. The exclusive filtering takes precedence over inclusive filtering. The pattern is using Ant-path style pattern. Multiple patterns can be specified separated by comma. For example to exclude all classes starting with Bar use: **/Bar* To exclude all routes form a specific package use: com/mycompany/bar/* To exclude all routes form a specific package and its sub-packages use double wildcards: com/mycompany/bar/** And to exclude all routes from two specific packages use: com/mycompany/bar/*,com/mycompany/stuff/* | List of | |
Used for inclusive filtering scanning of RouteBuilder classes. The exclusive filtering takes precedence over inclusive filtering. The pattern is using Ant-path style pattern.

The set selected by this option can be narrowed down by Note that Quarkus extensions typically register the required classes for reflection by themselves. This option is useful in situations when the built in functionality is not sufficient. Note that this option enables the full reflective access for constructors, fields and methods.
