spring singleton bean circular reference solution

return bean

get

bean cache level 2

singletonFactoriesHashMap(16)

earlySingletonObjectsHashMap(16)

DI operation circular ref

bean cache level 1

if null

afterSingletonCreationthis.singletonsCurrentlyInCreation.remove(beanName)

doCreateBean

populateBeanDI operation

put bean into earlySingletonObjects

bean cache level 3

remove from singletonFactories

mark that bean is creating

DI

initializeBeanAOP operation and  get final bean

beforeSingletonCreation(this.singletonsCurrentlyInCreation.add(beanName))

singletonsCurrentlyInCreationSet(16)

getBean

addSingletonthis.singletonObjects.font color=\"#009900\

get singleton bean(singleton)

create bean

addSingletonFactoryif (!this.singletonObjects.containsKey(beanName)) {  this.earlySingletonObjects.remove(beanName);  this.singletonFactories.font color=\"#4d9900\

check if singleton is currentlyin creation
