Question

I find @RequestMapping is very usable in the controller class. This annotation based controller maps a url to a method instead to a class. Also I dont need to bloat the spring-servlet.xml for handler mapping.

But with this it looks like only @Autowired or @Resource is possible for the dependency injection. Is there any other way?

And how bad its to use @Resource in the production code?

Answer 1

It is not bad at all. Using @Autowired / @Resource / @Inject is a perfectly normal way of specifying injection points.

One drawback of @Resource (that has nothing to do with production vs development) is the it relies on strings, which are not checked at compile-time. Instead you can use @Qualifier if you need to specify a concrete implementation for injection, rather than an interface.
