调用程序：
Ioc ioc = new NutIoc(new JsonLoader("/conf/ioc/ dao.js"));
DataSource ds = ioc.get(DataSource.class);
报错：

Exception in thread "main" org.nutz.ioc.IocException: IocBean[dataSource] throw Exception when creating

若调用程序改为：
Ioc ioc = new NutIoc(new JsonLoader("/conf/ioc/dao.js"));
DataSource ds = ioc.get(DruidDataSource.class);
报错为：

Exception in thread "main" org.nutz.ioc.IocException: IocBean[druidDataSource] For object [druidDataSource] - type:[class com.alibaba.druid.pool.DruidDataSource]

完整启动日志发一下

另外，这是做测试吗？ nutz mvc下不需要新建NutIoc实例的

是做测试

dao.js 贴一下

var ioc = {
	dataSource : {
		type : "com.alibaba.druid.pool.DruidDataSource",
		events : {
			create : "init",
			depose : 'close'
		},
		fields : {
			driverClassName:"com.mysql.cj.jdbc.Driver",
			url : "jdbc:mysql://localhost:3306/nutz?serverTimezone=Asia/Shanghai",
			username : "root",
			password : "root",
			testWhileIdle : true, // 非常重要,预防mysql的8小时timeout问题
			maxWait : 15000, // 若不配置此项,如果数据库未启动,druid会一直等可用连接,卡住启动过程
			maxActive : 100
			defaultAutoCommit : false
		// 提高fastInsert的性能
		}
		dao:{
			type:"org.nutz.dao.impl.NutDao",
			args:[{refer:"dataSource"}]
		}
	}
}

dao怎么在dataSource里面?

改过后可以了，万分谢谢！：）
