Jfinal-weixin配置连接池报错

DruidPlugin mysqlPool = new DruidPlugin(PropKit.get("jdbcUrl"),PropKit.get("user"),PropKit.get("password"));

me.add(mysqlPool);

ActiveRecordPlugin arpMysql = new ActiveRecordPlugin("mysql", mysqlPool);

me.add(arpMysql);

arpMysql.addMapping("msg_news", "id",MsgNews.class);

以上是在configPlugin中配置的连接，启动项目时就直接报错。
