# springboot-jpa-studies
The goal of this project is to study `JPA Batch Processing` (i.e, insert/update/delete a set of records in a single command), `JPA Locking` and `Datetime in JPA`.
## Proof-of-Concepts & Articles
On [ivangfr.github.io](https://ivangfr.github.io), I have compiled my Proof-of-Concepts (PoCs) and articles. You can easily search for the technology you are interested in by using the filter. Who knows, perhaps I have already implemented a PoC or written an article about what you are looking for.
## Modules
- ### [jpa-batch](https://github.com/ivangfr/springboot-jpa-studies/tree/master/jpa-batch#jpa-batch)
- ### [jpa-locking](https://github.com/ivangfr/springboot-jpa-studies/tree/master/jpa-locking#jpa-locking)
- ### [jpa-datetime](https://github.com/ivangfr/springboot-jpa-studies/tree/master/jpa-datetime#jpa-datetime)
## Prerequisites
- [`Java 17+`](https://www.oracle.com/java/technologies/downloads/#java17)
- [`Docker`](https://www.docker.com/)
## Start Environment
- Open one terminal and inside `springboot-jpa-studies` root folder run:
```
docker compose up -d
```
- Wait for Docker containers to be up and running. To check it, run:
```
docker compose ps
```
## Useful Commands
- **MySQL**
- Run `MySQL` interactive terminal (`mysql`)
```
docker exec -it -e MYSQL_PWD=secret mysql mysql -uroot --database studiesdb
```
> Type `exit` to exit
- **PostgreSQL**
- Run `Postgres` interactive terminal (`psql`)
```
docker exec -it postgres psql -U postgres -d studiesdb
```
> Type `\q` to exit
## Shutdown
- In a terminal, make sure you are in `springboot-jpa-studies` root folder;
- To stop and remove docker compose containers, networks and volumes run:
```
docker compose down -v
```
## Running tests
- In a terminal, make sure you are in `springboot-jpa-studies` root folder;
- The commands below will run the test cases of all modules. In order to run just the tests of a specific module check the module README;
During the tests, [`Testcontainers`](https://www.testcontainers.org/) starts automatically Docker containers of the databases before the tests begin and shuts the containers down when the tests finish;
> **Note**: jpa-datetime producer and consumer don't have test cases
- **Using MySQL**
```
./mvnw clean test -DargLine="-Dspring.profiles.active=mysql-test"
```
- **Using PostgreSQL**
```
./mvnw clean test -DargLine="-Dspring.profiles.active=postgres-test"
```
## TODO
- Fix `jpa-locking` tests when using PostgreSQL.
