title: Spring services should be serializable
body: <p>I am developing Spring-mvc application.</p>
  
  <p>I am getting <code>NotSerializableException</code>.</p>
  
  <p>The exception is coming on the restart of the server. I search for the solution and got to know that session scoped beans should be serialized.</p>
  
  <p>My session scoped bean implements serializable, but it gives exception for injected beans and services.</p>
  
  <p>It asks me to serialize all injected beans and services.</p>
  
  <p>I have serialized my beans but is it required to serialize services also.</p>
  
  <p>Is it accepted behavior to serialize services also?
  If yes then will I have to serialize all the services in my applications?</p>
  
  <p>Thanks.</p>
