spring-bean

I'm currently working on a rabbit-amqp implementation project and use spring-rabbit to programmatically setup all my queues, bindings and exchanges. (spring-rabbit-1.3.4 and spring-framework versions 3.2.0) The declaration in a javaconfiguration class or xml-based configuration are both quite static in my opinion declared.

I'm using Spring Beans with annotations and I need to choose different implementation at runtime. @Service public class MyService { public void test(){...} } For example for windows's platform I need MyServiceWin extending MyService , for linux platform I need MyServiceLnx extending MyService . For now I know only one horrible solution: @Service public class MyService { private MyService impl; @PostInit public void init(){ if(windows) impl=new MyServiceWin(); else impl=new MyServiceLnx(); } public void test(){ impl.test(); } } Please consider that I'm using annotation only and not XML config.

I have a similar question here Guice with multiple concretes......picking one of them with a solution for Guice. But I have a different project using spring di (beans), but with the same kind of issue. I have an interface with N number of concretes. (3 here) public interface OrderProcessorInterface { void ProcessOrder(String preferredShipperAbbreviation, Order ord); } public class FedExShipper implements ShipperInterface { private Log logger; public FedExShipper(Log lgr) { if (null == lgr) { throw new IllegalArgumentException("Log is null"); } this.logger = lgr; } public void ShipOrder(Order

I want to create a Spring bean in Spring Java configuration with some constructor arguments passed at runtime. I have created the following Java config, in which there is a bean fixedLengthReport that expects some arguments in constructor. @Configuration public class AppConfig { @Autowrire Dao dao; @Bean @Scope(value = "prototype") **//SourceSystem can change at runtime** public FixedLengthReport fixedLengthReport(String sourceSystem) { return new TdctFixedLengthReport(sourceSystem, dao); } } But i am getting error that sourceSystem couldn't wire because no bean found. How can I create bean
