Equivalent of @Bean without Spring

Question

How to make the same thing without Spring ? I don't know how to declare the bean using specific constructor.

Usually I would do it with Spring this way, but right now I can't use Spring.

@Configuration public class ClientConfig { @Bean public MyApi myApi() { return Feign.builder().target(MyApi.class, myUrl); } }

And use injection in another class.

public class AnotherClass { @Inject MyApi myApi; }

How to "declare" the bean? Today I'm using a singleton and it is 'ugly', so thanks in advance for any advice.

Did you try with @Inject annotation (Java EE CDI Dependency Injection) — Narayan Yerrabachu

You can use producer method which creates desired injectable bean. It's good practice to put producer methods in separated bean:

@Dependent public class Resources { @Produces @Default public MyApi myApi() { return Feign.builder().target(MyApi.class, myUrl); } }

you can use @Inject MyApi myApi anywhere you need it then.

For more info see the CDI documentation http://weld.cdi-spec.org/.
