PostgreSQL is an open-source relational database technology. Spring has a robust integration with this technology: Spring Data JPA.

The first step is to choose the database that you would like to use in your project. Define the driver for PostgreSQL and the Java dependencies. Then determine the DataSource client using the Java configuration reader library.

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import sh.platform.config.Config;
import sh.platform.config.PostgreSQL;

import javax.sql.DataSource;

public class DataSourceConfig {

    @Bean(name = "dataSource")
    public DataSource getDataSource() {
        Config config = new Config();
        PostgreSQL database = config.getCredential("database", PostgreSQL::new);
        return database.get();
