问题
We are upgrading from Camel v2.13 to v2.16 and discovered that beanRef() has been marked as deprecated. What is the replacement/alternative recommended by Apache Camel. I was unable to find anything useful on Camel v2.16.0 Documentation site. Even updated examples are not yet available.
beanRef() is syntax within Java DSL Bean Language of Camel.
回答1:
I assume that you are talking about the ProcessorDefinition class.
The javadoc comments say to use the bean(...) methods as replacements for the beanRef(...) methods.

回答2:
from(...).to("bean:beanId?method=myMethod")
OR
from(...).bean("beanId", "myMethod")
