Update the samples and integration tests to use Java 8. There's no
specific reason to keep them on Java 6 and it helps keep Eclipse happy
if we upgrade.
A dependency on org.glassfish.jersey.ext:jersey-bean-validation has
been added to spring-boot-starter-jersey. jersey-bean-validation’s EL
dependencies have been excluded in favour of those provided by
spring-boot-starter-tomcat (or starter-jetty or starter-undertow should
the user choose to use a different embedded container).
Closes gh-2315
If you inject the class (via a servlet parameter) it seems that
Jersey tries to create all the beans for you (and fails). I thought
it was supposed to work (according to the docs), so I'm a bit confused
but the sample now has Spring DI and the tests pass.
Fixes gh-1981
Jersey 2 has some Spring support built in but it's a bit awkward to
use in a Boot app, so autoconfiguration seems appropriate. The tests
and sample show how to use it, but the short story is that any
@Component can define JAX-RS endpoints via @GET etc.
There's a sample for Jersey 1 as well (pay careful attention to
the plugin configuration if you want to build an executable jar)
Fixes gh-1651
