Cascade Created Spring Bean Circular Dependency

Spring application fails to start with 'circular dependency' error after Cascade added new beans. Bean A depends on Bean B which depends on Bean A, creating an unsolvable dependency graph. The application cannot instantiate beans in any order.

Cascade likely generated beans without understanding dependency injection order.

Error Messages You Might See

BeanCurrentlyInCreationException: circular dependency The dependencies of some beans form a cycle Cannot instantiate bean due to circular reference
BeanCurrentlyInCreationException: circular dependencyThe dependencies of some beans form a cycleCannot instantiate bean due to circular reference

Common Causes

  1. Cascade added @Autowired field creating circular dependency between services
  2. Two beans depend on each other through constructor injection (no lazy loading)
  3. Cascade created bean that depends on itself indirectly through multiple hops

How to Fix It

Review bean dependencies - look for circular patterns. Use setter injection or lazy loading with @Lazy. Refactor to break cycle: extract common dependency into third service. Use ObjectProvider for optional late-binding. Consider if services should be split or combined differently.
