From the client side, if I want to access a web service, I would simply generate a proxy for it using wsimport. That is my web service reference.

Where then does the annotation @WebServiceRef come into play? Is it meant to be used at the server side only, to obtain injected references to web services hosted in the same environment?

不一定，但它确实取决于服务器实现。例如，要访问远程服务，它需要能够访问生成的客户端以及可选的 WSDL 文档和方案文件（按照惯例应该在 中WEB-INF/wsdl），这样

public class HelloServlet extends HttpServlet {

    @WebServiceRef(HelloMessengerService.class) // class with @WebServiceClient
    private HelloMessenger port; // the SEI

    ...
}

该类HelloMessengerService是存根并具有具有属性的@WebServiceClient注释 wsdlLocation（指向本地或远程 WSDL 文档）。

但你可以有类似的东西

@WebServiceRef(wsdlLocation = "META-INF/wsdl/AnyService/Any.wsdl")
private HelloMessengerService service;

或者

@WebServiceRef
public HelloMessengerService service;

如果您使用处理程序链来更改传入和传出的 SOAP 消息：

@WebServiceRef(HelloMessengerService.class)
@HandlerChain(file="handler-chain.xml")
private HelloMessenger port;

注释的使用@WebServiceRef必须应用于 JAX-WS 管理的客户端，如 Servlet、EJB 或其他 Web 服务。

只是为了补充 Paul Vargas 的回答，@WebServiceRef注释是一个工具，用于完成 Java EE 平台向完全托管环境的演变。这样想：

Almost every component within the Java EE stack is injectable by some means, EJBs, JSF managed beans, CDI beans, @Resources etc. Why not be able to inject a webservice reference? With the ability to inject a webservice reference using this annotation, the following are ready injection targets:

  • EJBs
  • Servlets (under Servlet 3.0)
  • JSF Managed Beans
  • CDI Beans
  • MDBs
