使用jfinal源码在jetty上运行出错? 400 报错

@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
