Spring / Spring Beans

What are the limitations of autowiring in Spring framework?

Autowiring fails on primitives, multiple same-type beans without @Qualifier, and circular constructor dependencies. It also cannot inject final fields without a constructor.

  • Overriding: You can still specify dependencies using and settings which will always override autowiring.
  • Primitive data types: You cannot autowire simple properties such as primitives.
  • Confusing nature: Autowiring is less exact than explicit wiring, so if possible prefer using explicit wiring.
