用druid 连接 postgresql ，启动报错

Question

@JFinal 你好，想跟你请教个问题：

我用druid 连接 postgresql ，启动报错，（配置ActiveRecord插件后）

代码如下：

public void configPlugin(Plugins me) { // 配置C3p0数据库连接池插件  //C3p0Plugin c3p0Plugin = new C3p0Plugin(getProperty("jdbcUrl"), getProperty("user"), getProperty("password").trim());  //me.add(c3p0Plugin);   druidPlugin = new DruidPlugin(getProperty("url"),
         getProperty("username"),
         getProperty("password"),
         getProperty("driverClassName")); druidPlugin.start();
   me.add(druidPlugin); // 配置ActiveRecord插件  ActiveRecordPlugin arp = new ActiveRecordPlugin(druidPlugin);
   me.add(arp);
   arp.addMapping("blog", Blog.class); // 映射blog 表到 Blog模型 }

报错日志：
