JPA: persisting Collections of Enum

Event Sourcing using spring application events

see:

1. service/**/src/main/java/daggerok/history/applicationevent

2. service/**/src/main/java/daggerok/history/service

http :8080/rest/engineers username=tttest | jq '._links.self'
http :8080/rest/histories | jq '._embedded.histories'

Event Sourcing (history) using spring data-rest

see:

1. service/**/src/main/java/daggerok/history/springdatarest

2. service/**/src/main/java/daggerok/history/service

http :8080/rest/domains firstName=1 lastName=1 username=1 | jq '._links.self'
http :8080/rest/domains firstName=2 lastName=2 username=2 | jq '._links.self'
http :8080/rest/otherDomains test=1 | jq '._links.self'
http :8080/rest/histories | jq '._embedded.histories'

Embedded primitive @OneToMany and @ManyToMany relationships

see: service/**/src/main/java/daggerok/relationships

@OneToMany → @Embeddable Set emails (also could be a list)

@ManyToMany → @Embeddable Map tags (same for labels)

gradle compileQuerydsl xjc # gradle assemble
gradle bootRun

http ":8080/api/v4/engineers?size=2&page=0&sort=username,desc"

gradle --stop
gradle composeDown

Optimization: 3NF

see: service/**/src/main/java/daggerok/embedded

examine REST API using HTTPie:

http :8080/api/v3/predicate
http ":8080/api/v3/predicate?second.secondField1=1"

# bash
http ":8080/api/v3/predicate?createdDate=$(date +%Y-%m-%d)"
# fish
http ":8080/api/v3/predicate?createdDate="(date +%Y-%m-%d)

http ":8080/api/v2/pagination?page=0&size=1&sort=first.firstField1,desc"
http ":8080/api/v2/sorted?sort=id,desc"

http :8080/api/v2/flatten
http :8080/api/v2/flatten/2

note: see .travis.yml for cURL examples

generate Q-classes from JPA:

gradle compileQuerydsl xjc

quick startup

bootstrapping docker before bootRun

gradle bootRun
open http://localhost:8080 # press enter
...
gradle composeDown
gradle --stop

integration tests

see docker subproject

gradle clean assemble test
gradle --stop

spring data jpa auditing

see service/**/src/main/java/daggerok/audit package

• spring-boot, spring-data, spring-web, fallback 404 handler

• JPA auditing

• Performance optimization: de-normalize JPA NF4 → NF3, @Embedded, @Embeddable

• QueryDSL (spring-data integration)

• Event sourcing using spring data-rest and spring application events

• gradle, SoapUI

• Postgres, Docker
