Why IDEA Warns on @Autowired but Not on @Resource: A Spring DI Overview

IDEA flags @Autowired field injection but not @Resource because Spring advises against field injection—seeing it as tightly coupled and hard to test—while @Resource is a standard JSR‑250 annotation, so the IDE applies the warning only to the Spring‑specific @Autowired usage.

Understanding Spring DI: @Autowired vs @Resource and Field Injection Pitfalls

Spring supports constructor, setter, and field injection, but field injection is discouraged; @Autowired (Spring‑specific, by‑type) and @Resource (standard, by‑name) differ in defaults and IDE warnings, so prefer constructor injection for required beans, setter injection for optional ones, and only use @Resource for unavoidable field injection to lessen container coupling.
