Spring boot使能http/2协议

Question

我正在使用Spring boot 1.5.12 (JDK8)和嵌入式Undertow服务器1.4，我已经在我的属性中使用了'server.https.enabled: true‘来启用http2协议，但它似乎不起作用。我也有自己签署的证书安全连接。当我在浏览器上加载我的应用程序(Angular 5)时，我仍然得到http/1.1协议。

下面是我的SpringBootApplication类中的内容：

@SpringBootApplication
@EnableEurekaClient
@EnableOAuth2Sso
public class Application extends WebSecurityConfigurerAdapter {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    @Override
    public void configure(HttpSecurity http) throws Exception {
        //some authorization configuration
    }
}

Application.properties文件

security:
  require-ssl: true
server:
  ssl:
    enabled: true
  http2:
    enabled: true
   port: 8085
    ssl:
      key-store: classpath: keystore.p12
      key-store-type: PKCS12
      key-alias: devel
      key-store-password: pass
      key-password: pass
eureka:
  client:
    serviceUrl:
      defaultZone: https://localhost:8761/eureka
  instance:
    preferIpAddress: false
    securePortEnabled: true
    securePort: ${server.port}

还有什么我需要配置的吗？

提前感谢

Answer 1

尝试将以下bean添加到配置中：

@Bean
UndertowEmbeddedServletContainerFactory embeddedServletContainerFactory() {
    UndertowEmbeddedServletContainerFactory factory = new UndertowEmbeddedServletContainerFactory();
    factory.addBuilderCustomizers(
            builder -> builder.setServerOption(UndertowOptions.ENABLE_HTTP2, true));
    return factory;
}

属性server.http2.enabled在spring boot 1.5.13中不存在。请参阅this
