学习ioc,根据文档demo,没看出来哪里错写错了啊。
js:

var ioc = {
    xiaobai : {
        name : 'XiaoBai',
        birthday : '2009-10-25 15:23:40'
    },
    xiaohei : {
        type : 'org.nutz.demo.Pet', // 类型
        singleton : false, // 是否为单件
        args : [ 'XiaoHei' ], // 构造函数参数
        fields : {
            birthday : '2009-11-3 08:02:14',
            friend : {refer : 'xiaobai'}    // 指向容器里另外一个对象
        }
    }
}
    @Test
    public void test_get_xiaohei() {
        Ioc ioc = new NutIoc(new JsonLoader("pet.js"));
        Pet pet = ioc.get(null, "xiaohei");
        System.out.println(pet.getBirthday().getTimeZone().getID());
        System.out.println(pet.getName());
        ioc.depose();
    }

ioc.get()方法指定类型或者null都报错。nutz使用1.r.65-SNAPSHOT版本
日志如下:

先获取小白,使其类型确定,然后再获取小黑

@Test
    public void test_get_xiaohei() {
        Ioc ioc = new NutIoc(new JsonLoader("pet.js"));
        Pet xiaobai = ioc.get(Pet.class,"xiaobai");
        Pet pet = ioc.get(null, "xiaohei");
        System.out.println(pet.getBirthday().getTimeZone().getID());
        System.out.println(pet.getName());
        ioc.depose();
    }

如大神指点,无错误。
根据下面这段文档理解的话,感觉容易误解。

如果配置文件中声明了类型,则可不传入类型
Pet xh = ioc.get(null, "xiaohei");
System.out.printf("%s's friend is %s\n", xh.getName(), xh.getFriend().getName());

感谢秒回。回复信息在浏览器这边提示出来,是什么技术?

html5的notify api
