Dependency Injection

[kri shan]

@Autowired / @Resource / @Inject using these spring annotations we can inject the dependencies into spring bean. All three annontations does same thing. Is there any difference ?

[Bill Gorder]

There are some, I typically use @Autowired in my applications because I have no intention of moving away from Spring. Of course I still need @Resource for wiring in Collections(of non spring beans) as @Autowired handles this differently. However the main differences come down to name vs type. Whatever approach you choose just stay consistent throughout the application.

Here is a more detailed look at it.
