             Summary: Spring Boot startup failure when running executable war file with libraries containing TypeConverter services file and classes annotated @Converter
                 Key: CAMEL-9058
                 URL: https://issues.apache.org/jira/browse/CAMEL-9058
             Project: Camel
          Issue Type: Bug
          Components: camel-spring-boot
    Affects Versions: 2.15.2
         Environment: Mac OS X
Java 8

            Reporter: pavan dinavahi
            Priority: Critical


When running Camel within Spring Boot and using Smooks, the AnnotationTypeConverterLoader is not able find any @Converter annotated classes with the Spring Boot Executable War file, this causes a startup failure of the Spring Boot application. The @Converter annotated classes are within the Smooks library within WEB-INF/lib/ of the Spring Boot generated executable War file. 

The AnnotationTypeConverterLoader default strategy is using the Resolver's findAnnotated method for loading @Converter annotated classes within the WAR. There is no way to configure a custom TypeConverterLoader within CamelContext or SpringCamelContext either. 
 
I had to rebuild the Smooks library without the META-INF/services/org/apache/camel/TypeConverter file to get the application running.
 
Please note that this was not an issue when running Spring Boot using "gradle bootRun".
