picoservice

Picoservice is a java library for service registration and service lookup. With it, you can find classes that have special meaning in your project. Internally it uses java's ServiceLoader so it integrates nicely with you build tools. Nothing magical is happening here.

Picoservice is focused on its main purpose: registration and lookup. For registration, you have to annotate a custom annotation with @PicoService. Each class annotated with that custom annotation can afterwards be found by using IPicoRegistry.INSTANCE.find(Class<C> pSearchedType, Class<A> pAnnotationClass).

Get started

The easiest way to get started with picoservice is using the following snippet in your pom.xml.

<dependency>
  <groupId>de.adito.picoservice</groupId>
  <artifactId>picoservice</artifactId>
  <version>1.1.7</version>
</dependency>

Example of usage

Custom annotation which is put on classes for registration:

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.TYPE)
@PicoService
public @interface TestAnno
{
  int value();
}

Annotated class 1:

@TestAnno(10)
public class TestAnnotated
{
}

Annotated class 2:

@TestAnno(20)
public class TestAnnotated2
{
}

Find those classes:

public class Test
{
  public static void main(String[] args)
  {
    Map<Class<?>, TestAnno> map = IPicoRegistry.INSTANCE.find(Object.class, TestAnno.class);
  }
}
