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.

What’s new in JHipsterLand?

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

14. 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);
});
}
}

15. 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)

24. Get Started with JHipster 4 Demo

25. AAA Sonar Rating

26. JHipster Libraries

27. Thoughtworks Radar

32. Continuous Integration and Deployment
$ yo jhipster:ci-cd
Supports:
Jenkins pipeline
Travis CI
GitLab CI
CircleCI jhipster.github.io/setting-up-ci/

34. Deploying to Production
Cloud Foundry
Heroku
Kubernetes
AWS
AWS with Boxfuse

35. Deploy to Google Cloud with Kubernetes
1. Convert a monolith to a microservice gateway
hibernateCache: “hazelcast”
serviceDiscovery: “eureka”
applicationType: “gateway”
2. Create microservices app and generate entities
3. Create UI for entities on gateway using yo jhipster:entity
4. Clone JHipster Registry in same directory and prove it all works

36. Deploy to Google Cloud with Kubernetes
5. Create a sub-directory alongside apps and run yo jhipster:kubernetes
6. Create a Google Cloud project - console.cloud.google.com
7. Set project using gcloud config set project $project-name
8. Create a cluster:
gcloud container clusters create demo --machine-type=n1-
standard-2 --scopes cloud-platform
9. Authenticate:
gcloud auth application-default login --no-launch-browser

37. Deploy to Google Cloud with Kubernetes
10. Run kubectl commands to deploy
11. Use port-forwarding to see registry locally:
kubectl port-forward jhipster-registry-0 8761:8761
12. Scale microservice apps as needed:
kubectl scale deployment store --replicas=3

38. Microservices with Docker Demo
