Quick Start

1. Add worm as a dependency.

Maven

<repository>
    <id>eldonexus</id>
    <url>https://eldonexus.de/repository/maven-public/</url>
</repository>

<dependency>
    <groupId>de.paul2708</groupId>
    <artifactId>worm</artifactId>
    <version>0.2.0</version>
</dependency>

Gradle

repositories {
    maven("https://eldonexus.de/repository/maven-public/")
}

dependencies {
    implementation("de.paul2708:worm:0.2.0")
}

2. Define an entity.

@Entity("persons")
public class Person {

  @Identifier
  @MaxLength(128)
  @Attribute("email_address")
  private String email;

  @Attribute("age")
  private int age;

  @Reference
  @Attribute("partner")
  private Person partner;

  @Attribte("passwords")
  private List<String> passwords;

  public Person() {

  }
}

3. Create a repository.

public interface PersonRepository extends CrudRepository<Person, String> {

  List<Person> findByAge(int age);
}

4. Create a MySQL database and store the first entity.

Database database = new MySQLDatabase("localhost", 3306, "database", "user", "password");
PersonRepository repository = Repository.create(PersonRepository.class, Person.class, database);

Person person = new Person();
// ...

repository.save(person);
