Bootstrap Hyperon Runtime with Spring Boot Starter (since version 2.1.0)

Prerequisites

• Java 11
• Maven 3.x
• Spring Boot

Maven configuration

Apart from standard spring bootdependencies, you need to include hyperon-runtime-spring-boot-starter dependency, available in Maven Central.

Add hyperon-runtime-spring-boot-starter dependency to pom.xml file:

 
<dependency>
		<groupId>pl.decerto</groupId>
		<artifactId>hyperon-runtime-spring-boot-starter</artifactId>
		<version>${hyperon-runtime.version}</version>
</dependency> 

Another needed dependency is the JDBC driver to the database of choice, e.g., h2, oracle, mssql, postgresql:

 
<dependency>
		<groupId>com.h2database</groupId>
		<artifactId>h2</artifactId>
		<version>${h2-database.version}</version>
</dependency>

Properties

With the above setup, all the configuration that is needed is application.properties file with database properties:

 
hyperon.database.url=<jdbc_url>
hyperon.database.username=<username>
hyperon.database.password=<password>

By default, by including hyperon-runtime-spring-boot-starter Spring Boot with try to auto-configure HyperonEngine component using previously supplied database properties failing with adequate message if properties are not available.

Using auto-configured HyperonEngine

After successfully configuring properties while starting the application, spring will create HyperonEngine bean available in the spring application context, which can then be injected anywhere:

 
@Component
public class HyperonClient {
	@Autowired
	private HyperonEngine engine;
}

Overriding default configuration

To override default auto-configuration, you need to define HyperonEngine bean in the @Configuration class:

 
@Bean
public HyperonEngine hyperonEngine() {
	HyperonEngineFactory factory = new HyperonEngineFactory();
	return factory.create();
}

Existing auto-configured DataSource and HyperonRuntimeProperties can be used simply by injecting them:

 
public HyperonEnginehyperonEngine(
	HyperonRuntimeProperties properties,
	@Qualifier("hyperonDataSource") DataSource dataSource
) {}

Disabling Hyperon

If you want to disable hyperon temporarily for some reason, you can do it with property hyperon.runtime.enabled set to false:

 
hyperon.runtime.enabled=false
