publicclass IoCServlet extends ActionSupport implements SessionAware, ServletRequestAware, ServletResponseAware {

    private Map session;
    private HttpServletRequest request;
    private HttpServletResponse response;    

    //set注入Session，struts2把session封裝成了一個Map
    publicvoid setSession(Map session) {
        this.session= session;
    }
    //set注入request對象
    publicvoid setServletRequest(HttpServletRequest request) {
        this.request = request;
    }
    //set注入response對象
    publicvoid setServletResponse(HttpServletResponse response) {
        this.response = response;
    }

    @Override
    public String execute() {        
        //方法中能夠對session、request、response進行操做
