是否可以将 WebClient 配置为使用 reactor-http-nio 线程池以外的自定义线程池(使用 Netty 时)?如果可能,我们能否以某种方式限制该自定义线程池仅在特定处理器内核上运行?
最佳答案
是的。你可以。
{
Intger THREADS = 10;
BasicThreadFactory THREADFACTORY = new BasicThreadFactory.Builder()
.namingPattern("HttpThread-%d")
.daemon(true)
.priority(Thread.MAX_PRIORITY)
.build();
EXECUTOR = new ThreadPoolExecutor(
THREADS,
THREADS,
0L,
TimeUnit.MILLISECONDS,
new LinkedBlockingQueue<>(),
THREADFACTORY,
new ThreadPoolExecutor.AbortPolicy());
NioEventLoopGroup RESOURCE= new NioEventLoopGroup(THREADS,EXECUTOR);
}
@Bean
public ReactorResourceFactory reactorResourceFactory(NioEventLoopGroup RESOURCE) {
ReactorResourceFactory f= new ReactorResourceFactory();
f.setLoopResources(new LoopResources() {
@Override
public EventLoopGroup onServer(boolean b) {
return RESOURCE;
}
});
f.setUseGlobalResources(false);
return f;
}
@Bean
public ReactorClientHttpConnector reactorClientHttpConnector(ReactorResourceFactory r) throws SSLException {
SslContext sslContext = SslContextBuilder
.forClient()
.trustManager(InsecureTrustManagerFactory.INSTANCE)
.build();
return new ReactorClientHttpConnector(r, m -> m.secure(t -> t.sslContext(sslContext)));
}
@Bean
public WebClient webClient(ReactorClientHttpConnector r) {
return WebClient.builder().clientConnector(r).build();
}
如果你想对 WebServer 使用相同的。对 ReactiveWebServerFactory 做同样的配置。
@Bean
public ReactiveWebServerFactory reactiveWebServerFactory(NioEventLoopGroup RESOURCE) {
NettyReactiveWebServerFactory factory = new NettyReactiveWebServerFactory();
factory.addServerCustomizers(hs->hs.tcpConfiguration(s->s.runOn(RESOURCE)));
return factory;
}
