JHipster is an application generator that allows you to create monoliths or microservices, based on Spring Boot and Angular. It leverages Spring Cloud for microservices and contains best-of-breed JavaScript and CSS libraries for creating your UI. In this session, you’ll learn about what’s new in JHipster. Topics include Angular 4, Progressive Web Apps, HTTP/2, JUnit 5 and Spring 5.

#DevoxxPL

13. HTTP/2
Binary, instead of textual
Fully multiplexed, instead of ordered and blocking
Can use one connection for parallelism
Uses header compression to reduce overhead
Allows servers to “push” responses proactively into client caches

17. HTTP/2 in JHipster
/*
* Enable HTTP/2 for Undertow - https://twitter.com/ankinson/status/829256167700492288
* HTTP/2 requires HTTPS, so HTTP requests will fallback to HTTP/1.1.
* See the JHipsterProperties class and your application-*.yml configuration files
* for more information.
*/
if (jHipsterProperties.getHttp().getVersion().equals(JHipsterProperties.Http.Version.V_2_0)) {
if (container instanceof UndertowEmbeddedServletContainerFactory) {
((UndertowEmbeddedServletContainerFactory) container)
.addBuilderCustomizers((builder) -> {
builder.setServerOption(UndertowOptions.ENABLE_HTTP2, true);
});
}
}

18. HTTP/2 in JHipster
# ===============================================================================================
# To enable SSL, generate a certificate using:
# keytool -genkey -alias blog -storetype PKCS12 -keyalg RSA -keysize 2048 -keystore keystore.p12 -validity 3650
#
# You can also use Let's Encrypt:
# https://maximilian-boehm.com/hp2121/Create-a-Java-Keystore-JKS-from-Let-s-Encrypt-Certificates.htm
#
# Then, modify the server.ssl properties so your "server" configuration looks like:
#
# server:
# port: 8443
# ssl:
# key-store: keystore.p12
# key-store-password: <your-password>
# keyStoreType: PKCS12
# keyAlias: blog
# ===============================================================================================
jhipster:
http:
version: V_1_1 # To use HTTP/2 you will need SSL support (see above the "server.ssl" configuration)
