实际开发中，可能很多人会用到uuid,nutz貌似没有提供这方面的东东，建议是不是可以加个uuid生成什么的

实现也很简单
java.util.UUID.randomUUID().toString().replace("-", "");

@id(auto=false)可不可以在这里搞个GeneratorType，可以参考下JPA ID生成策略

考虑扩展使用
@JsonField(by="")的生成器机制

现在nutz支持这种EL标注
@name
@column("id")
@Prev(els = @el("$me.initUUID()"))
protected String id;

public String initUUID() {
    if (this.id == null)
        return UUID.randomUUID().toString();
    return this.id;
}

我觉得可以满足上面提到的主键生成策略问题
