Question

We are using Struts2-Spring integration and all my action classes implement SessionAware, sample code to action class and their spring definition is given below,

public class IRXxxxAction extends ActionSupport implements SessionAware {
  private Map session;

  public String execute()
  {//}

  public void setSession(Map<String, Object> session)
  {
    this.session = session;
  }
} 

Spring Configuration

<bean name="userAction" class="com.IRXxxxAction" >
    <property name="adminDAO" ref="adminDAO" />
</bean>

If I understand correctly, each auto-wired property will be a singleton, so if the above is true, is there anyway that the session map get shared between two simultaneous requests?

Answer 1

You have asked same question on the user mailing list and as said if you are using Struts2-Spring plugin make sure to put bean scope as prototype.

Struts2 create new instance of action on each request, since action work as a model also and in order to make it thread safe a new object is being created on each request and placed on value stack.

Not proving scope will be treated by Spring as singleton and for ever request same action instance will be given back which can leads to a lot of issue from data corruption to weird behavior.
