Jersey:如何访问全局应用程序对象？

@Path("/example")
public class ExampleResource {
    @Context
    private HttpServletRequest request;

    @GET
    public String getExample() {
        // 使用注入的HttpServletRequest对象
        String ipAddress = request.getRemoteAddr();
        // 其他业务逻辑
        return "Example response";
    }
}

@Path("/example")
@ApplicationScoped
public class ExampleResource {
    private int counter = 0;

    @GET
    public String getExample() {
        // 使用共享的counter状态
        counter++;
        return "Example response: " + counter;
    }
}
