----------------------------------------
Summary: camel-bean: @Handler annotation doesn't work with
FunctionalInterfaces
Key: CAMEL-17844
URL: https://issues.apache.org/jira/browse/CAMEL-17844
Project: Camel
Issue Type: Bug
Components: camel-bean
Affects Versions: 3.4.1
Reporter: Bjørn Ole Myrold
Version 3.4.1 introduced fixes in regards to how `BeanInfo` gets built, this
seems to break beans which are `@FunctionalInterface`s.
I believe it was introduced with
https://issues.apache.org/jira/browse/CAMEL-15278
The fix created in the above case only handles super classes, and does not look
at interfaces. A lambda cast to a `FunctionalInterface` will only provide
`Object` as super class, and `BeanInfo` will then not find any methods marked
with `@Handler` in the interface.
This works in 3.4.0, but not in 3.4.1
{code:java}
public class TestRoute extends RouteBuilder {
@Override public void configure() throws Exception {
from("direct:testRoute").id("TestRoute")
.setBody().method((Formatter) a -> String.format("%s %s",
a.getName(), a.getOtherName()))
.to("direct:testEndpoint");
}
@FunctionalInterface
public interface Formatter {
@Handler String test(@Body RandomPojo t);
}
} {code}
