Circular dependencies between beans managed by Spring is usually caused by a logic error, but it may be sometimes exactly what developers intend to obtain.

We recently ran into this problem: Spring seems to “over-eagerly” initialize the beans, resulting in a circular dependency error.

2007-04-05 13:24:41,310 ERROR [main] context.ContextLoader (ContextLoader.java:205) – Context initialization failed
org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name ‘articleManager’: Bean with name ‘*********’ has been injected into other beans [******, **********, **********, **********] in its raw version as part of a circular reference,
but has eventually been wrapped (for example as part of auto-proxy creation). This means that said other beans do not use the final version of the bean. This is often the result of over-eager type matching – consider using ‘getBeanNamesOfType’ with the ‘allowEagerInit’ flag turned off, for example.

We managed to overcome the problem by using the “lazy-init” attribute for our Spring beans. Other techniques for avoiding/fixing the problems are described by Costin Leau and Andreas Senft on the spring framework’s forums here and here.
