java - Ehcache of spring doesn't work correctly between microservices -

i have monolithic application.according microservices appearance , needs adapt appearance splited small apps.you assume after splinting each microservice has model has 1 object same in microservices.the following example clearing.

into micro1:

class { private object obj;  //getter , setter } 

into micro2:

class b { private object obj;  //getter , setter } 

and object obj has own repository , service , controller layer.
there config of ehcash of spring @ save method service layer of model. this:

@transactional @override @caching(evict = { @cacheevict(value = "obj", key = "#obj.id" ) }) public integer save(object obj) {     //code here } 

it working when application monolithic after spliting because of obj dependency microservices , method(save method) repeated each microservice,the ehcash doesn't work correctly.
how do when each microservice affects object obj other microservices aware to.

there many solution can in problem , redis have integration spring , can use sloving problem , can read more in link

also there solutions likes hazelcast , it's datagrid , more simple key-value cache.
