Answer 1

如Spring Boot reference documentation所述，您可以使用@Component public class MyNettyWebServerCustomizer implements WebServerFactoryCustomizer<NettyReactiveWebServerFactory> { @Override public void customize(NettyReactiveWebServerFactory factory) { factory.addServerCustomizers(new EventLoopNettyCustomizer()); } } class EventLoopNettyCustomizer implements NettyServerCustomizer { @Override public HttpServer apply(HttpServer httpServer) { EventLoopGroup eventLoopGroup = //...; return httpServer.tcpConfiguration(tcpServer -> tcpServer.bootstrap(serverBootstrap -> serverBootstrap.group(eventLoopGroup))); } }自定义Reactor Netty Web服务器。

这是Spring Boot 2.1的一个例子：

您可以更改依赖项：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <exclusions>
        <!-- Exclude the Tomcat dependency -->
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<!-- Use Jetty instead -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-jetty</artifactId>
</dependency>
