Registry Startup

It is possible to provide extra logic to be executed at Registry startup, by making contributions to the RegistryStartup service configuration.

...

Here's an example of a module that makes a contribution:

Code Block
java
java

public class MyModule
{
  public static void contributeRegistryStartup(OrderedConfiguration<Runnable> configuration)
  {
    configuration.add("MyContributionName", new Runnable() { ... });
  }
}

Generally, these contributions are in the form of inner classes; if they were services, they could just be eagerly loaded.

Startup Methods

Since
since5.2

Instead of making contributions to the RegistryStartup service configuration you can provide startup methods inside your modules. A startup method is a static or instance method of a module annotated with @Startup annotation. Each module is allowed to contain several startup methods.

java

public class MyModule
{

  @Startup
  public static void initMyApplication(Logger logger, MyService service)
  {
    logger.info("Starting up...");

    service.init();
  }
}
