How to use Jersey 2 with Spring IoC container

Question

What is the best way to enable injection of spring beans into Jersey 2? Jersey seems to not support this natively.

What is needed to wire the 2 frameworks together?

Answer 1

Jersey 2.3 has now spring support:

https://jersey.github.io/documentation/latest/user-guide.html#spring

As stated in the documentation

The Spring extension module configuration is based on annotations

So you have to tell spring to scan your classpath, for example:

and annotate your resource class with a spring annotation (I advise to use @Component, and then specify the jersey resource scopes @Singleton/@PerLookup/@RequestScoped )

@Component
@Singleton
@Path("example")
public class Example {

    //Spring beans can't be injected directly into JAX-RS classes by using Spring XML configuration
    @Autowired
    private MyOtherBean myOtherBean;

    @GET @Path("hello")
    public String hello() {
        return myOtherBean.hello();
    }
}
