shiro配置问题，我配置了缓存然后自己重写了一个Realm，冲突：报错

public class MyShiroRealm extends AuthorizingRealm {

	@Override
	protected AuthorizationInfo doGetAuthorizationInfo(
			PrincipalCollection principals) {

		return null;
	}

	@Override
	protected AuthenticationInfo doGetAuthenticationInfo(
			AuthenticationToken authcToken) throws AuthenticationException {
		UsernamePasswordToken token = (UsernamePasswordToken) authcToken;
		return null;
	}

}

shiro.ini配置文件信息

[main]
shiroDbRealm = com.XXX.MyShiroRealm
securityManager.realms = $shiroDbRealm

sessionManager = org.apache.shiro.web.session.mgt.DefaultWebSessionManager

securityManager.sessionManager = $sessionManager
cacheManager = org.apache.shiro.cache.ehcache.EhCacheManager
