shiro的配置可以添加在spring的配置文件中。但是为了便于管理我们再单独创建一个shiro的配置文件，里面的Schema还是spring的。

自定义realm
自定义realm一定要继承AuthorizingRealm，可以重写doGetAuthenticationInfo来实现认证方法，可以重写doGetAuthorizationInfo来实现授权方法

MyRealm extends AuthorizingRealm

MyRealm

    /**
     * 认证的方法
     */
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException 
        // 获取登录的账号
        UsernamePasswordToken upToken = (UsernamePasswordToken) token;
        String username = upToken.getUsername();
        System.out.println("登录提交的账号:" + username);
        // 去数据库中查询
        List<User> list = userService.login(username);
        if (list == null || list.size() != 1) 
            return null;
        
        User user = list.get(0);
        System.out.println("user:" + user);
        return new SimpleAuthenticationInfo(user.getUsername(), user.getPwd(), new SimpleByteSource(user.getSalt()),
                "myrealm");
