Guice

java 代码

google 的新Ioc容器 号称快spring100倍

小例子:

public interface Service {
void go();
}

===

public class ServiceImpl implements Service {
public void go() {
   System.out.println("go go go a le a le a le");
}
}

===

public class Client {
private final Service service;
@Inject
public Client(Service service) {
   this.service = service;
}
public void go(){
   service.go();
}
}

===

public class MyModule implements Module {
public void configure(Binder binder) {
   binder.bind(Service.class).to(ServiceImpl.class).in(Scopes.SINGLETON);
}
}

===

public static void main(String[] args) {
   Module myModule = new MyModule();
   Injector injector = Guice.createInjector(myModule);
   Client client = injector.getInstance(Client.class);
   client.go();
}
