Programmer's action

Spring2.08 webwork2.24
There is a problem with the service injected into the Action. The injected service is not the same object as the referenced service.
Whether it is a singleton or not, the service referenced in the execute method is null, and the service in the setter method is valid when the initialization is declared as singleton="true".
Or declaring the service as static is no problem.

Action

Java code Collection code
public class SystemAction extends ActionSupport implements ModelDriven{ 
    SystemModel sm = new SystemModel(); 
    private SystemService systemService; 
     
    public String execute() throws Exception { 
        System.out.println("in execute systemservice is "+systemService); 
        systemService .TestSystemDAO(); 
        return SUCCESS; 
    } 
 
..setter.. Omit

Similar problems were also found in javae ,but. . Still not solved
http://www.iteye.com/post/139291

solved it.
The original default is to declare the service that injects action according to the name
in webwork.properties
, and that's it. . . vomiting blood. . .
webwork.objectFactory.spring.autoWire = type
