What's New in JHipsterLand - DevNexus 2017

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 explored include Angular 2, Progressive Web Apps, HTTP/2, JUnit 5, and Spring 5.

  9. 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

  10. 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);
    });
    }
    }

  11. 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:
    # 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)
