拦截器拦截非法访问

Action部分，BaseAction未给出，JdbcUtils未给出

package erchou;

import java.util.List;

import org.apache.struts2.ServletActionContext;

public class HelloAction extends BaseAction{
	private Admin admin;
	
    public Admin getAdmin() {
		return admin;
	}

	public void setAdmin(Admin admin) {
		this.admin = admin;
	}


	public String login(){
		Admin ad = null;
		try {
			ad = JdbcUtils.isAdmin(admin);
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		if(ad!=null){
			session.put("info", admin);
			return "success";
		}
    	return "wrong";
    }
	
	public String showList() {
		try {
			List list = JdbcUtils.getAdmin();
			
			requset.put("admins", list);
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		return "showList";
	}
}

import com.opensymphony.xwork2.interceptor.AbstractInterceptor;

public class UserInterceptor extends AbstractInterceptor{
	public String intercept(ActionInvocation invocation) throws Exception {
		ActionProxy proxy = invocation.getProxy();
		String methodName = proxy.getMethod();
		ActionContext ac = invocation.getInvocationContext();
		if(!"login".equals(methodName)){
			Object object = ac.getSession().get("info");
			if(object==null){
				return "wrong";
			}else{
				return invocation.invoke();
