tomcat8.5支持jdk1.8吗_tomcat jdk版本

最近接收到任务要让公司的框架支持Http2协议，主要是RPC之间走Http2。通过查找官网以及上网找资料和咨询大神的帮助，终于找到以下两种方式，蠢人不多话，直接上代码。网上大多数都是抄来抄去的，所以希望本文能帮助到大家，共同学习吖
springboot2.1.4 + tomcat9 +java 8 
这个方法是我从外网查找到的，但是缺点就是需要额外的再开一个端口来接收h2c的请求
有兴趣想看原文的可以点击以下的网址进行查看 ，简书也有对这篇文章有翻译过
点击这里可看原文

@Configuration
public class Http2cServletContainer { 
   

    @Bean
    public ServletWebServerFactory servletContainer() { 
   
        TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory();
        tomcat.addAdditionalTomcatConnectors(createH2cConnector());
        tomcat.addConnectorCustomizers();
        return tomcat;
    }

    private Connector createH2cConnector() { 
   
        Connector connector = new Connector();
        Http2Protocol upgradeProtocol = new Http2Protocol();
        connector.addUpgradeProtocol(upgradeProtocol);
        connector.setPort(8089);
        return connector;
    }
}

最近看看了最新的springboot的稳定版2.2.2 发现可以使用新的方式来升级，请看代码，这种方式就不需要开通另外一个端口来进行接收，但是得升级版本
springboot官方文档

@Component
public class H2cServletTomcatContainer implements WebServerFactoryCustomizer<TomcatServletWebServerFactory> { 
   

    @Override
    public void customize(TomcatServletWebServerFactory factory) { 
   
        TomcatProtocolHandlerCustomizer handler = s -> s.addUpgradeProtocol(new Http2Protocol());
        factory.addProtocolHandlerCustomizers(handler);
    }
}

容器启动后，看看有没有出现这个，出现了就ok了

接下来是关于jetty的支持，这个是通过问大佬的
需要剔除springboot 内置的tomcat，使用jetty容器，也要引入jetty的server包需要自己去查一下对应的版本信息

 <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web</artifactId>
            <exclusions>

            <version>9.4.24.v20191120</version>
        </dependency>

@Configuration
public class JettyH2cConfiguration { 
   
    private final JettyServerCustomizer serverCustomizer = server -> { 
   
        for (Connector connector : server.getConnectors()) { 
   
            if (connector instanceof ServerConnector) { 
   
                final ServerConnector serverConnector = (ServerConnector)connector;

                final HTTP2CServerConnectionFactory serverConnectionFactory =
                        new HTTP2CServerConnectionFactory(new HttpConfiguration());
                serverConnector.addConnectionFactory(serverConnectionFactory);
            }
        }
    };

    /** * for spring-webflux */
    @Bean
    public JettyReactiveWebServerFactory jettyReactiveWebServerFactory() { 
   
        final JettyReactiveWebServerFactory serverFactory = new JettyReactiveWebServerFactory();
        serverFactory.addServerCustomizers(serverCustomizer);
        return serverFactory;
    }

    /** * for spring-mvc */
    @Bean
    public JettyServletWebServerFactory jettyServletWebServerFactory() { 
   
        final JettyServletWebServerFactory serverFactory = new JettyServletWebServerFactory();
        serverFactory.addServerCustomizers(serverCustomizer);
        return serverFactory;
    }

看jetty启动后的输出

基本配置完应该就没有问题了，很多东西都可以在官网上看到的，多看官网，多问大佬，成就人生哈哈哈
