Description

In such a configuration class

public class MyConfiguration {

    @BindToRegistry
    public ClientConfiguration myClientConfig() {
        ClientConfiguration cc = new ClientConfiguration();
        cc.setMaxConnections(5);
        return cc;
    }

    @BindToRegistry
    public MyBean myBean(@PropertyInject("hi") String hi, @PropertyInject("bye") String bye) {
        // this will create an instance of this bean with the name of the method (eg myBean)
        return new MyBean(hi, bye);
    }

    @BindToRegistry
    public AmazonS3 myAmazon(@BeanInject("myClientConfig") ClientConfiguration config) {
        return AmazonS3Client.builder().withRegion("US-EAST-1").withClientConfiguration(config).build();
    }

    public void configure() {
        // this method is optional and can be removed if no additional configuration is needed.
    }

}

We could detect that the myAmazon method has a parameter of type ClientConfiguration which we can attempt to lookup as singleton bean. Then you can do

    @BindToRegistry
    public AmazonS3 myAmazon(ClientConfiguration config)
