Installation

Raspberry

• Git installation
• Maven installation
• Java installation
• Login via gh auth login
• Clone repositories

uwe@raspberrypi4:~/SoftwareProjects/eclipse-workspace $ git clone https://github.com/UweHeuer/uweheuer-backend.git
uwe@raspberrypi4:~/SoftwareProjects/eclipse-workspace $ gh repo clone UweHeuer/uweheuer-frontend

Build

• build by Maven
• setup on computer see here
• steering of target environments by profiles in pom.xml:
  • local_dev (default)
  • heroku

Development Laptop

• jar-file

C:\Uwes\SoftwareProjects\eclipse-workspace\uweheuer-backend>mvn -DskipTests package

Raspberry

• get updates from repository

uwe@raspberrypi4:~/SoftwareProjects/eclipse-workspace/uweheuer-backend $ git pull

• jar-file

uwe@raspberrypi4:~/SoftwareProjects/eclipse-workspace/uweheuer-backend $ mvn -DskipTests package

Docker

• build image on all computers

<PROJECT_PATH> docker build --tag uweheuerbackend .

Run

Local from Command Line

C:\Uwes\SoftwareProjects\eclipse-workspace\uweheuer-backend>mvn spring-boot:run -Dspring-boot.run.arguments="--spring.datasource.password=mHalloo0@1m --spring.datasource.username=root --uweheuer.bookmarks.import.dbuser=root --uweheuer.bookmarks.import.dbpwd=mHalloo0@1m --uweheuer.bookmarks.parole=jakobthimo123456"

Local from Eclipse

• run MySQL
• create Eclipse Run Configuration (picture outdated)
  • this creates a file UweHeuerBackend Run SpringBoot Run Configuration.launch in C:\Uwes\SoftwareProjects\eclipse-workspace\.metadata\.plugins\org.eclipse.debug.core\.launches\
    • if eclipse error occurs and run configuration is empty see here. Add the two missing lines with value of project name 'uweheuer-backend'.

Docker Compose

• run all containers

uwe@raspberrypi4:~/SoftwareProjects/eclipse-workspace/uweheuer-backend $ docker compose --env-file .compose.env up -d // using an local env file, run in background

• stop all containers

uwe@raspberrypi4:~/SoftwareProjects/eclipse-workspace/uweheuer-backend $ docker compose --env-file .compose.env down

Implementation

Spring Boot Standard Diagnosis Actuator

• adding Spring Boot Actuator by adding to pom.xml:

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

• adding to application.properties all endpoints

management.endpoints.web.exposure.include=*

• add class ActuatorHttpExchangesConfiguration for HTTP request logging

Set Build Timestamp

• see pom.xml below spring-boot-maven-plugin and
• AdminController.java BuildProperties attribute

Logging

• uses Logback
• see /src/main/resource/log-back-spring.xml
  • log files go to ./logs/ directory
• in a Docker environment /logs/ is mapped via .compose.env to a local machine directory
