ActiveRecordPlugin 这样配置的！
public void configPlugin(Plugins me) {
// 配置 druid 数据库连接池插件
DruidPlugin druidPlugin = new DruidPlugin(PropKit.get("jdbcUrl"), PropKit.get("user"), PropKit.get("password").trim());
me.add(druidPlugin);
// 配置ActiveRecord插件
ActiveRecordPlugin arp = new ActiveRecordPlugin(druidPlugin);
// 所有映射在 MappingKit 中自动化搞定
_MappingKit.mapping(arp);
me.add(arp);
}
