JFinal 非web项目多数据源 arp报错 Config already exists?报错

@JFinal 你好，想跟你请教个问题：

JFinal 非web项目多数据源 arp启动第二次的时候会报错 已经存在

C3p0Plugin c3p0Plugin = new C3p0Plugin();
c3p0Plugin.start();
ActiveRecordPlugin arp = new ActiveRecordPlugin(c3p0Plugin);
arp.start();


C3p0Plugin c3p0Plugin1 = new C3p0Plugin();
c3p0Plugin1.start();
ActiveRecordPlugin arp1 = new ActiveRecordPlugin(c3p0Plugin1);
arp1.start();

arp1.start();这里报错

Exception in thread "main" java.lang.IllegalArgumentException: Config already exists: main
