@JFinal 你好,想跟你请教个问题:

在jetty上跑之后出现了以下问题

我的数据库连接配置是这样的

C3p0Plugin cp = new C3p0Plugin("jdbc:mysql://localhost/guard", "root", "root");
  me.add(cp);
  ActiveRecordPlugin arp = new ActiveRecordPlugin(cp);
  arp.setShowSql(true);
  me.add(arp);

为什么会有这个错误,没有用到druid,为什么错误会和druid相关?

后来我改用druid,配置如下

 DruidPlugin druidPlugin = new DruidPlugin("jdbc:mysql://localhost/guard", "root", "root");
       druidPlugin.setInitialSize(3).setMaxActive(10);
       me.add(druidPlugin);
       // 配置ActiveRecord插件
       ActiveRecordPlugin arp = new ActiveRecordPlugin(druidPlugin);
运行时出现如下错误

 想问下,这个log类型转换是在jfinal里做的吗,有办法可以解决吗
