I have created spring-boot application with tomcat 9.0.16, spring-boot 2.1.3.RELEASE, JDK1.8. When I am making curl post request with --http2 its saying "curl: (56) Recv failure: Connection reset by peer".
but when I use --http-prior-knowledge it works fine.
my application.property file
server.port=8080
server.http2.enabled=true
and congif file
@Bean
public WebServerFactoryCustomizer tomcatCustomizer() {
return (container) -> {
if (container instanceof TomcatServletWebServerFactory) {
((TomcatServletWebServerFactory) container)
.addConnectorCustomizers((connector) -> {
connector.addUpgradeProtocol(new Http2Protocol());
});
}
};
}
- for curl -vvv --http2 -H 'Content-Type: application/json' -H 'cache-control: no-cache' -XPOST http://localhost:8080/save -d '{"xyz":"xyz"}' logs of curl->
