JAX RS 客户端 API 拦截器

当使用 JAX RS 客户端 API 时，有没有办法通过拦截器将标头添加到请求中，而不是通过显式设置标头：

Client client = ClientBuilder.newClient();
Response response = client.target("someUrl").path("somePath").request().get();

以AOP方式

创建一个ClientRequestFilter http://docs.oracle.com/javaee/7/api/javax/ws/rs/client/ClientRequestFilter.html:

@Provider
public class MyClientRequestFilter implements ClientRequestFilter {

    @Override
    public void filter(ClientRequestContext requestContext) throws IOException {
        requestContext.getHeaders().add("Authorization", "value");
    }
}

并将其注册到您的Client http://docs.oracle.com/javaee/7/api/javax/ws/rs/client/Client.html:

Client client = ClientBuilder.newClient().register(MyClientRequestFilter.class);
