How to build [WIP]

For the moment, to build this project you should

1. fetch and build the core project

   git clone https://github.com/informatici/openhospital-core.git
   cd openhospital-core
   mvn clean install -DskipTests=true
   

2. clone and build this project

   git clone https://github.com/informatici/openhospital-api
   cd openhospital-api
   mvn clean install -DskipTests=true
   

3. prepare settings from each rsc/*.dist file

   rsc/application.properties <- set a SHA-256 jwt token
   rsc/database.properties
   rsc/log4j2-spring.properties
   rsc/...
   

4. set target/rsc/database.properties

   DB can be created with `docker-compose up` from `openhospital-core` or using a dedicated MySQL server
   

5. start openhospital-api (in target folder)

   # Windows
   java -cp "openhospital-api-0.1.0.jar;rsc/;static/" org.springframework.boot.loader.launch.JarLauncher
   
   # Linux
   java -cp "openhospital-api-0.1.0.jar:rsc/:static/" org.springframework.boot.loader.launch.JarLauncher
   

6. call services

   • URL base: http://localhost:8080
   • URL login: http://localhost:8080/auth/login
   • URL patients: http://localhost:8080/patients
   • URL swagger: http://localhost:8080/swagger-ui/index.html

You can see Swagger API Documentation at: http://localhost:8080/swagger-ui/index.html

7. enable LAN networking

   # set in application.properties
   ...
   server.address=0.0.0.0 # or the machine server IP
   ...
   

Using Swagger-UI

1. use endpoint /auth/login to login and get the token

2. use the Authorize button at the top of the Swagger-UI, paste the token from step #1 and click Authorize

3. close the dialog

4. now all the endpoints are automatically secured and the token will be added to the request

Using Postman

1. import postman_collection.json in your Postman installation

How to build a war file

1. Prepare settings from each rsc/*.dist file

### Note: 
### server.address, server.port, server.servlet.context-path and server.tomcat.accesslog.* will be ignored
### jwt.token.secret <- set a SHA-256 jwt token
### api.host <- set to openhospital-api-0.1.0 (<artifactId>-<version>) or any <appname> that will match <appname>.war
rsc/application.properties

### note: if the DB is on the host, use 'host.docker.internal' as hostname
rsc/database.properties

### note: if the DB is on the host, use 'host.docker.internal' as DBSERVER
rsc/log4j2-spring.properties

### as required in [Admin Doc](https://github.com/informatici/openhospital-doc/blob/develop/doc_admin/AdminManual.adoc#settings-properties)
rsc/settings.properties

2. Build war file

### OH-core must have been built and available in .m2 (Maven) repo
./mvnw clean install -DskipTests=true -P war

3. (Optional) rename war to the desired <appname>.war:

mv /target/openhospital-api-0.1.0.war <appname>.war

How to deploy backend in Docker environment

Make sure you have docker with docker-compose installed, then run the following commands:

• copy dotenv file into .env and set variables as needed (the SHA-256 jwt token is needed)
• run make
• run docker compose up -d database (wait for some seconds the very first time to build the DB)
• (optional - demo data after set the database container, English only) run docker compose run --rm oh-database-init
• run docker compose up backend

When done successfully, head over at http://localhost:[API_PORT]/swagger-ui/index.html

You can change the deployment branch using the .env file.

NOTE:

• API should be already available from LAN at http://your-server-ip:[API_PORT]
• Swagger will be available at http://[API_HOST]:[API_PORT]/swagger-ui/index.html

How to generate openapi specs

Make sure to have API started without errors.

Run the Maven command and it will overwrite the openapi/oh.yaml

mvn springdoc-openapi:generate

To redirect the output to another file, use:

mvn springdoc-openapi:generate -Dspringdoc.outputFileName=my_revision.yaml

Cleaning

docker compose rm --stop --volumes --force
make clean
make clean-all # remove deps/ folder

Code style

This project uses a consistent code style and provides definitions for use in both IntelliJ and Eclipse IDEs.

IntelliJ IDEA instructions

For IntelliJ IDEA the process for importing the code style is:

• Select Settings in the File menu
• Select Editor
• Select Code Style
• Expand the menu item and select Java
• Go to Scheme at the top, click on the setting button by the side of the drop-down list
• Select Import Scheme
• Select IntelliJ IDE code style XML
• Navigate to the location of the file which relative to the project root is: .ide-settings/idea/OpenHospital-code-style-configuration.xml
• Select OK
• At this point the code style is stored as part of the IDE and is used for all projects opened in the editor. To restrict the settings to just this project again select the setting button by the side of the Scheme list and select Copy to Project.... If successful a notice appears in the window that reads: For current project.

Eclipse instructions

For Eclipse the process requires loading the formatting style and the import order separately.

• Select Preferences in the Window menu
• Select Java
• Select Code Style and expand the menu
• Select Formatter
• Select the Import... button
• Navigate to the location of the file which relative to the project root is: .ide-settings/eclipse/OpenHospital-Java-CodeStyle-Formatter.xml
• Select Open
• At this point the code style is stored and is applicable to all projects opened in the IDE. To restrict the settings just to this project select Configure Project Specific Settings... in the upper right. In the next dialog select the openhospital repository and select OK. In the next dialog select the Enable project specific settings checkbox. Finally select Apply and Close.
• Back in the Code Style menu area, select Organize Imports
• Select Import...
• Navigate to the location of the file which relative to the project root is: .ide-settings/eclipse/OpenHospital.importorder
• Select Open
• As with the formatting styles the import order is applicable to all projects. In order to change it just for this project repeat the same steps as above for Configure Project Specific Settings...
