Old Fashioned way:

Since you have already initialized the ContextLoaderListener a simple trick is to use the WebApplicationContext to retrieve your beans at any application point:

WebApplicationContext ctx = WebApplicationContextUtils.getRequiredWebApplicationContext(servletContext);
SomeBean someBean = (SomeBean) ctx.getBean("someBean");

Jersey Support:

Or you can use the annotation based discovery, since Jersey has already support for Spring DI. You have to register your beans under your main application entry point. That entry point, in below example will be some.package.MyApplication, should be provided as an of the servlet container:

  SpringApplication
  org.glassfish.jersey.servlet.ServletContainer
  
    javax.ws.rs.Application
    some.package.MyApplication

Register you beans in your application:

package some.package;

import org.glassfish.jersey.server.ResourceConfig;
import org.glassfish.jersey.server.spring.scope.RequestContextFilter;

public class MyApplication extends ResourceConfig {
  public MyApplication () {
    register(RequestContextFilter.class);
    register(SomeBean.class);
    // ...
  }
}

Here you can take a look to a ready to run example from Jersey Git repo.
