following your hint I removed all spring references and replacing
.to("bean:testBean?scope=Request")
with
.bean(TestBean.class, BeanScope.Request)
I now have the expected behavior.
My goal is to instantiate a dataSource with request scope and reference it
in the sql component like this
.to("sql:classpath:sql/gsl/show_search_path.sql?dataSource=postgresDataSource")
but I don't know how to tell it to take the specific instance that I just
created.
Any suggestions?
