The question of how to inject a Spring bean by ID is a regular on the
mailing list . The documentation provides a reasonable explanation of how to
inject spring beans or the context (
http://tapestry.apache.org/integrating-with-spring-framework.html), e.g:
@Inject
private UserDAO userDAO;
This should find an implementation of the UserDAO and inject it into the
page/component. If there are multiple implementations of the same service,
there would be an error , and then the page author will have to do something
like:
@Inject
private ApplicationContext springContext;
public void someMethod() {
UserDAO userDao = (UserDAO) springContext.getBean("userDaoId")
}
Thus, the question that pops into my head is : if there is just this one
extra line, how come Tapestry doesn't do it for me ? Maybe it wouldn't use
the same generic @Inject annotation, maybe it could use some extra
annotation or something to specify the ID (in the spring context) of the
spring bean to be injected, e.g. :
@Inject @SpringId("myUserDao")
private ApplicationContext springContext;
