I understand how I could perform member injection to achieve my desired
result. However, I'd prefer to use only constructor injection. If I could
use constructor injection, then the constructor could be used with our
without Guice.
One idea is to rewrite the fields of the annotations of constructor
parameters. In the example below, x.y.z.Foo's constructor would be
rewritten* by a Guice listener* of some sort as:
package x.y.z
Foo ( @Settings("param1") String x )
or better yet:
Foo( @Settings String param1 )
is rewritten as:
package x.y.z
Foo ( @Settings("x.y.z.Foo.param1") String param1 )
Then, I could use the equivalent of the Named facility to inject a value
for x. Is this possible?
