EzyJPA Configuration

1. Configuration List

EzyJPA provides a list of configurations in bellow table:

#	Property	Default Value	Description
1	datasource.jdbc_url	null	JDBC connection url
2	datasource.username	null	Datasource's username
3	datasource.password	null	Datasource's password
4	datasource.driver_class_name	null	JDBC driver class name
5	datasource.database_name	null	Database name

You can encrypt sensitive configuration like username, password if you want and please take a look HikariCP to find out another configuration.

2. An Example

You can put bellow configuration to your application.yaml file:

# for application.yaml
datasource:
  jdbcUrl: jdbc:mysql://root:12345678@localhost:3306/test
  driverClassName: com.mysql.cj.jdbc.Driver

Or for application.properties file:

# for application.properties
datasource.jdbcUrl=jdbc:mysql://root:12345678@localhost:3306/test
datasource.driverClassName=com.mysql.cj.jdbc.Driver

3. Auto Configuration

To configure automatically, you just need add configuration and add ezyfox-boot-autoconfigure to your project dependency like this:

<dependency>
    <groupId>com.tvd12</groupId>
    <artifactId>ezyfox-boot-autoconfigure</artifactId>
    <version>1.0.4</version>
</dependency>

4. Configure Manually

For some reason, you can not use ezyfox-boot-autoconfigure you can config like this:

import com.tvd12.ezydata.database.EzyDatabaseContext;
import com.tvd12.ezydata.jpa.EzyJpaDatabaseContextBuilder;
import com.tvd12.ezydata.jpa.loader.EzyJpaDataSourceLoader;
import com.tvd12.ezydata.jpa.loader.EzyJpaEntityManagerFactoryLoader;
import com.tvd12.ezyfox.bean.EzyBeanConfig;
import com.tvd12.ezyfox.bean.EzyPackagesToScanAware;
import com.tvd12.ezyfox.bean.EzySingletonFactory;
import com.tvd12.ezyfox.bean.EzySingletonFactoryAware;
import com.tvd12.ezyfox.bean.annotation.EzyAutoBind;
import com.tvd12.ezyfox.bean.annotation.EzyConfigurationBefore;
import com.tvd12.ezyfox.util.EzyPropertiesAware;
import lombok.Setter;

import javax.persistence.EntityManagerFactory;
import javax.sql.DataSource;
import java.util.Properties;
import java.util.Set;

import static com.tvd12.ezyfox.boot.util.EzyDatabaseContexts.addRepositoriesFromDatabaseContextToSingletonFactory;

@Setter
@EzyConfigurationBefore
public class EzyJpaConfiguration implements
    EzyBeanConfig,
    EzyPropertiesAware,
    EzySingletonFactoryAware {

    private Properties properties;
    
    @EzyAutoBind
    private EzySingletonFactory singletonFactory;

    @Override
    public void config() {
        addRepositoriesFromDatabaseContextToSingletonFactory(
            databaseContext(),
            singletonFactory
        );
    }

    private EzyDatabaseContext databaseContext() {
        return new EzyJpaDatabaseContextBuilder()
            .properties(properties)
            .entityManagerFactory(entityManagerFactory())
            .scan("your_package_to_scan")
            .build();
    }

    private EntityManagerFactory entityManagerFactory() {
        return new EzyJpaEntityManagerFactoryLoader()
            .entityPackages(packagesToScan)
            .dataSource(dataSource())
            .properties(properties)
            .load("Default");
    }

    private DataSource dataSource() {
        return new EzyJpaDataSourceLoader()
            .properties(properties, "datasource")
            .load();
    }
}
