var ioc = {
    config : {
        type : "org.nutz.ioc.impl.PropertiesProxy",
        fields : {
//            paths : ["custom/db.properties"]
            paths : ["../db.properties"]
        }
    }
}

1、看日志，config这个类已经进入ioc了

log.debug(Arrays.toString(IocMaster.getInstance().getNames()));

[allBeans] - [txREPEATABLE_READ, txREAD_COMMITTED, txNONE, littleBlueBird, txSERIALIZABLE, config, txREAD_UNCOMMITTED]

2、单元测试时，用has方法是通过的

Assert.assertTrue(IocMaster.getInstance().has("config"));

3、但是用get却get不到。这是为什么？

Assert.assertTrue(null != IocMaster.getInstance().get(PropertiesProxy.class));
