spring boot quartz scheduler

spring-boot-quartz-scheduler

Spring Boot + Quartz + vueJs(Vuetify) application.

Introduction:

The solution provide managing and scheduling jobs which makes HTTP calls to supplied endpoint. The good thing about the scheduler is that we can deploy it in clusters.(Inspired by quartz cluster mode setting)

System Requirements:

• OpenJDK for Java 1.8
• Git
• Project Lombok https://projectlombok.org
• Flyway schema migration tool

Building the example project:

Environment variable:

export DB_NAME='<your_db_name>'
export DB_HOST='<your_db_host>'
export DB_PORT='<your_db_port>'
export DB_USERNAME='<your_db_user>'
export DB_PASSWORD='<your_db_password>'

Quartz schema creation:

./gradlew flywayMigrate 
#Note : this is alreday initialise by spring hibernate.ddl-auto: update property

To build the fat JAR and run tests:

./gradlew build test

Jacoco tst coverage:

./gradlew jacocoTestReport

Run:

java -jar build/libs/spring-boot-quartz-scheduler-1.0-SNAPSHOT.jar
OR
./gradlew bootRun

Docker:

   ## build
   docker build -t needubey/quartz_scheduler
   
   # RUN
   docker run --name quartz_scheduler 
       -p 1234:1234 
       --env DB_NAME="quartz_scheduler" 
       --env DB_HOST="postgres" 
       --env DB_PORT="5432" 
       --env DB_USER_NAME="postgres" 
       --env DB_PASSWORD="postgres" 
       --detach 
       needubey/quartz_scheduler

Docker-Compose:

  postgres:
    container_name: postgres
    image: postgres
    environment:
      POSTGRES_DB: ${DB_NAME:-quartz_scheduler}
      POSTGRES_USER: ${DB_USERNAME:-postgres}
      POSTGRES_PASSWORD: ${DB_PASSWORD:-postgres}
      PGDATA: /data/postgres
    volumes:
      - postgres:/data/postgres
    ports:
      - "5432:5432"
    networks:
      - postgres
    restart: unless-stopped

swagger -> http://localhost:1234/swagger-ui.html

Assumptions:

• Vue js UI project could be run separately. However, we can run it together by copying the vue-app/dist/ to src/main/resources/static/ folder
• To generate the Vue js UI build follow ==> link to section
