在测试jfinal-demo时，改成tomcat启动。启动正常，只是有些资源404，改了路径就好了，但是在自己项目中，改用tomcat部署时就报错了，第一次用jfinal，求各位解答，具体报错如下：

五月 23, 2018 3:12:42 下午 org.apache.catalina.core.StandardContext filterStart

严重: Exception starting filter [jfinal]

其中报错的125行代码如下：

  // 配置ActiveRecord插件

        ActiveRecordPlugin arp = new ActiveRecordPlugin(druidPlugin);

        arp.setShowSql(true);

        // 统一全部默认小写,数据库字段不区分大小写

        arp.setContainerFactory(new CaseInsensitiveContainerFactory(true));

        // 所有映射在 MappingKit 中自动化搞定

        _MappingKit.mapping(arp);

        me.add(arp);

不知道怎么弄了，启动不了
