I found a solution myself, by extending RequestFactoryServelt and passing a
ServiceLayerDecorator. Note that it's possible to
implement functionality of ServiceLocator as a decorator here too.
Hope it will help someone else.
public class SpringRequestFactoryServelet extends RequestFactoryServlet {
private static final long serialVersionUID = 1L;
public static class SpringLocatorDecorator extends ServiceLayerDecorator {
private final ApplicationContext ctx;
public SpringLocatorDecorator(ApplicationContext ctx) {
super();
this.ctx = ctx;
}
@Override
public <T extends Locator<?, ?>> T createLocator(Class<T> clazz) {
return ctx.getBean(clazz);
}
}
public SpringRequestFactoryServelet() {
super(
new DefaultExceptionHandler(),
new SpringLocatorDecorator(
WebApplicationContextUtils.getWebApplicationContext(getThreadLocalServletContext())));
}
}
