是什么原因 造成的呢？

你贴的日志没有"报错"

snowflake忘记写@Inject ?

这个思路好像是对的private Snowflake snowflake; 这个没有以Bean的方式注入

<?xml version="1.0" encoding="UTF-8" ?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
	http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

       <bean id="snowflake" class="com.relops.snowflake.Snowflake" scope="singleton" >
              <constructor-arg value="1" />
       </bean>
</beans>

借鉴Spring的做法 ，nutz 应该怎么注入呢？

@Inject
private Snowflake snowflake;

哦, 那加个snowflake.js做ioc配置文件吧,放在dao.js同一个文件夹内

var ioc = {
    snowflake : {
        type : "com.relops.snowflake.Snowflake",
        args : [1]
    }
}

这样就ok啦！他的通过它@IocBy注入到 Ioc 容器中才能使用，非常谢谢
