请教关于工程启动加载session问题

[dunerunner]

小弟做了个struts2+spring小练习想启动工程时加载某些值到session中但是遇到问题了

applicationContext.xml:

<bean id="testAction" class="action.TestAction"></bean>
<bean id="init" class="action.TestAction" init-method="init"></bean>

TestAction:
public String execute() {
	Map session = ActionContext.getContext().getSession();
	System.out.println("ip: " + session.get("ip"));
	
	HttpServletRequest req = ServletActionContext.getRequest();
	HttpSession sess = req.getSession();
	System.out.println("ip: " + sess.getAttribute("ip"));

	return SUCCESS;
}

public void init() {
	System.out.println("init here!");
	Map session = ActionContext.getContext().getSession();
	HttpServletRequest req = ServletActionContext.getRequest();
	System.err.println("session == null: " + (session == null));
	System.err.println("request == null: " + (req == null));
	if (session != null) {
		session.put("ip", req.getLocalAddr());
	}
	if (req != null) {
		HttpSession sess = req.getSession();
		sess.setAttribute("ip", req.getLocalAddr());
	}
}

这里工程启动的时候输出的是：
init here!
session == null: true
request == null: true

action提交后输出的是：
ip: null
version: null
ip: null
version: null

请问 如何在工程启动的时候将需要的值 保存到session中 小弟就剩30分了所有分全部奉上了 谢谢！！

放session：
ActionContext ctx = ActionContext.getContext();
ctx.getSession().put("user", bean);

取session：
ActionContext ctx = ActionContext.getContext();
UserBean uBean = new UserBean();
uBean = (UserBean) ctx.getSession().get("user");
