java - multiple singleton beans referencing the same class -

-

i have java class lets 'class1' holds concurrenthashmap (to used cache) , functions update , remove entries in map.this class not designed singleton class. having discussion colleague, couldnt decide due couple of posts read on internet.i asking if okay this-

<bean id="reqrespcachemgr1" class="gravity.applications.rfqservice.reqrespgtwy.utility.reqrespcachemanager" scope="singleton">     </bean> <bean id="reqrespcachemgr2" class="gravity.applications.rfqservice.reqrespgtwy.utility.reqrespcachemanager" scope="singleton">     </bean> <bean id="reqrespcachemgr3" class="gravity.applications.rfqservice.reqrespgtwy.utility.reqrespcachemanager" scope="singleton">     </bean>

i trying create 3 singleton instances of same class..i think doesnt spoil meaning of singleton-ness because talking singleton scope in spring bean factory context , not class loader context.. know there alternate ways this.. having 3 concurrenthash maps in same class , using 1 singleton bean reference ,there trying create update , remove methods 3 maps in same class.

i hope didnt make confusing wanna know approach.i afraid im making improper use of design patterns..

let me know if question unclear

it seems need not singleton prototype

<bean id="reqrespcachemgr" class="gravity.applications.rfqservice.reqrespgtwy.utility.reqrespcachemanager" scope="prototype" />  class b1 {    @autowire    reqrespcachemanager cachemanager; }  class b2 {    @autowire    reqrespcachemanager cachemanager; }  class b3 {    @autowire    reqrespcachemanager cachemanager; }

all 3 beans new instance of reqrespcachemanager
