关于shiro的问题,会话管理器配置了 但是没有效果

Question

这个是spring

这个是realm

 package cn.ojama;

import java.util.ArrayList;
import java.util.List;

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.session.InvalidSessionException;
import org.apache.shiro.session.Session;
import org.apache.shiro.subject.PrincipalCollection;
import org.apache.shiro.subject.Subject;

import service.UserService;

import entity.User;

public class MyRealm extends AuthorizingRealm {
    private UserService    userService    = new UserService();

    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        String userCode = (String) principals.getPrimaryPrincipal();
        List<String> p = new ArrayList<String>();
        p.add("user:create");
        SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
        authorizationInfo.addStringPermissions(p);
        return authorizationInfo;

    }

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authcToken) throws AuthenticationException {
        UsernamePasswordToken token = (UsernamePasswordToken) authcToken;
        AuthenticationInfo authcInfo = new SimpleAuthenticationInfo(token.getUsername(), token.getPassword(), this.getName());
        return authcInfo;

这个是servlet 真心求教一下...配置了会话管理器,但是session还是半小时才失效,是我漏配置什么了吗?

 public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        String username = request.getParameter("username");
        String password = request.getParameter("password");
        Subject subject = SecurityUtils.getSubject();
        if (!subject.isAuthenticated()) {
            UsernamePasswordToken token = new UsernamePasswordToken(username, password);
            token.setRememberMe(true);
            UserService userService=new UserService();
        User user=    userService.getMemberByName(username);
            if(user==null){
                System.out.println("用户名或密码错误");
            }else{

            try {
                subject.login(token);
                response.sendRedirect("admin/index.jsp");
            } catch (Exception e) {
                System.out.println("用户名或密码错误");
            }
            }
        }
    }
