OnCompletion() in Apache Camel is called more than once

问题

In routeBuilder class it is having many routes, after completion of all routes need to call testMethod() but currently testMethod() method is calling many times

 .onCompletion().bean(TestProcessor.class,"testMethod").end()

//Router Class

     from(Source).setHeader("message", 

    body()).onCompletion().bean(TestProcessor.class,"testMethod").end().
    choice().when(header("camelfilenameonly").contains("test1.csv"))
   .unmarshal().bindy(BindyType.Csv,Test1CsvDto.class).bean(TestProcessor.class,
                        "processTest1Object").stop()

                .otherwise().choice()
                .when(header("camelfilenameonly").contains("test2.csv"))
                //Unmarshal csv
                .unmarshal().bindy(BindyType.Csv, Test2CsvDto.class).bean(TestProcessor.class,
                        "processTest2").stop()

any help would be appreciated..
