I reviewed Strut's internal codes and seems following works:
import org.apache.struts2.dispatcher.HttpParameters;
import org.apache.struts2.dispatcher.Parameter;
import org.apache.struts2.interceptor.HttpParametersAware;
import java.util.HashMap;
import java.util.Map;
/**

public class HttpParametersAwareAction implements HttpParametersAware {
@Override
public void setParameters(HttpParameters parameters) {
Map<String, Parameter> newParams = new HashMap<String,Parameter>();
for(String key :parameters.keySet()){
Parameter p = parameters.get(key);
if(p instanceof Parameter.Request){
newParams.put(key, new Parameter.Request(key, new
String[] {"new"+p.getValue()}));
}
}
parameters.appendAll(newParams);
}
}
