Question

我已经用tomcat 9.0.16，spring-boot 2.1.3.RELEASE，JDK1.8创建了spring-boot应用程序。当我使用--http2发出curl post请求时，它说“ curl：（56）Recv失败：对等重置连接”。

但是当我使用--http-prior-knowledge时，它工作正常。

我的application.property文件

server.port=8080
server.http2.enabled=true

和congif文件

@Bean
    public WebServerFactoryCustomizer tomcatCustomizer() {
        return (container) -> {
            if (container instanceof TomcatServletWebServerFactory) {
                ((TomcatServletWebServerFactory) container)
                        .addConnectorCustomizers((connector) -> {
                            connector.addUpgradeProtocol(new Http2Protocol());
                        });
            }
        };
    }

用于curl -vvv --http2 -H'内容类型：application / json'-H'缓存控制：no-cache'-XPOST http://localhost:8080/save -d'{“ xyz”：“ xyz” }' curl->

您不能使用POST方法执行HTTP / 1.1升级，因此Tomcat可能由于这个原因而阻塞了您的第一个请求（curl --http2 ...）。

我是Jetty的HTTP / 2实现者，在这种情况下，Jetty也不升级到HTTP / 2，尽管它以HTTP / 1.1 200响应请求，而不是阻塞。

将第一个请求转换为不带任何内容的GET，按预期，该升级在Jetty中成功，并带有HTTP / 1.1 101响应。

第二个请求不是HTTP / 1.1升级，而是先验的HTTP / 2请求；没有升级，因此对可以使用的HTTP方法没有限制，因此该请求在Jetty和Tomcat中均成功。

curl post请求不适用于选项--http2，但是当我使用--http2-prior-knowledge时，它工作正常
