Autowiring spring bean by name using annotation

Question

In Springs latest version, we can autowire a bean using annotation as @Autowired. This will autowire the bean using its type(or constructor, if applied on it).

Answer 1

You can use JSR-250 @Resource for by-name bean autowiring, unless you need constructor injection or multi-parameter method injection.

From the docs:

If you intend to express annotation-driven injection by name, do not primarily use @Autowired, even if is technically capable of referring to a bean name through @Qualifier values. Instead, use the JSR-250 @Resource annotation, which is semantically defined to identify a specific target component by its unique name, with the declared type being irrelevant for the matching process.
