Nutz解析Ioc的js配置文件的几个Bug！ #210

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
我用的是 Nutz1.a.27 版本，而且是Nutz文档里面ioc入门的例子。

第一个：相互引用的Bug
ioc配置文件pet.js
var ioc = {
    xiaohei : {
        type : 'nutz.ioc.demo.Pet',
        fields : {
            name : 'XiaoHei',
            birthday : '2010-05-31 00:40:50',
            friend : {
                refer : 'xiao3'
            }
        }
    },

    xiao3 : {
        type : 'nutz.ioc.demo.Pet',
        fields : {
            name : 'Xiao3',
            birthday : '1987-12-08 00:40:50',
            friend : {
                refer : 'xiaohei'
            }
        }
    }
}

客户端代码：
public class HelloPet {

    public static void main(String[] args) {
        Ioc ioc = new NutIoc(new JsonLoader("nutz/ioc/demo/pet.js"));
        Pet pet = ioc.get(null, "xiaohei");
        System.out.printf("%s - [%s]\n", pet.getName(),
pet.getBirthday().getTimeZone().getID());
        System.out.println(pet.getFriend().getName());
    }

}
直接抛 Exception in thread "main" java.lang.StackOverflowError 异常。

第二个：无法引用无类型定义的Bean
var ioc = {
    xiaobai : {
        name : 'XiaoBai',
        birthday : '2010-05-31 00:35:50'
    },

    xiaohei : {
        type : 'nutz.ioc.demo.Pet',
        fields : {
            name : 'XiaoHei',
            birthday : '2010-05-31 00:40:50',
            friend : {
                refer : 'xiabai'
            }
        }
    }
}
客户端代码同上，直接抛 Exception in thread "main"
org.nutz.ioc.IocException: For object [xiabai] - type:[null] 异常。
如果把friend定义改为
friend : {
    type : 'nutz.ioc.demo.Pet',
    refer : 'xiabai'
}
则打印：
XiaoHei - [Asia/Shanghai]
null
显然，还是无法生成或是引用名为‘xiaobai’的Bean。

第三个：莫名其妙的type字段
var ioc = {
    xiaohei : {
        type : 'nutz.ioc.demo.Pet',
        fields : {
            name : 'XiaoHei',
            birthday : '2010-05-31 00:40:50',
            friend : {
                refer : 'xiao3'
            }
        }
    },

    xiao3 : {
        type : 'nutz.ioc.demo.Pet',
        fields : {
            name : 'Xiao3',
            birthday : '1987-12-08 00:40:50',
            friend : {
                type : 'nutz.ioc.demo.Pet',
                refer : 'xiaohei'
            }
        }
    }
}
客户端代码同上，运行正常，打印：
XiaoHei - [Asia/Shanghai]
Xiao3
不过，如果在xiaohei的friend定义加上type，即：
xiaohei : {
    type : 'nutz.ioc.demo.Pet',
    fields : {
        name : 'XiaoHei',
        birthday : '2010-05-31 00:40:50',
        friend : {
            type : 'nutz.ioc.demo.Pet',
            refer : 'xiao3'
        }
    }
},
就会出错，打印：
XiaoHei - [Asia/Shanghai]
null
显然，还是引用名为‘xiao3’的Bean。

如果是
var ioc = {
    xiaohei : {
        type : 'nutz.ioc.demo.Pet',
        fields : {
            name : 'XiaoHei',
            birthday : '2010-05-31 00:40:50',
            friend : {
                type : 'nutz.ioc.demo.Pet',
                refer : 'xiao3'
            }
        }
    },

    xiao3 : {
        type : 'nutz.ioc.demo.Pet',
        fields : {
            name : 'Xiao3',
            birthday : '1987-12-08 00:40:50',
            friend : {
                refer : 'xiaohei'
            }
        }
    }
}
还是出错，打印：
XiaoHei - [Asia/Shanghai]
null

第一个问题, 已经有相关的issue
第二个问题, 
这是必然的,因为xiaohei没有type信息,根本无法进行创建. 
不过,这个使我想到相
关的一些问题.
第三个问题, 字段的type不能这样写的,请参阅

第二个问题: 应该写成:
friend : {
    refer : 'xiabai:nutz.ioc.demo.Pet'
}

如果用 {refer:'xxx'} 这里面不能再用 type 
了，否则，就不能表示一个引用。

现在明白了，相互引用只有在单例情况下才又意义。

friend : {
    refer : 'xiabai:nutz.ioc.demo.Pet'
}

xiaobai后面的的类型nutz.ioc.demo.Pet，理想情况下应该可以根据��
�它信息推断出来的吧。呵
呵……我的要求高了，何况自己也没什么贡献，而且要求实��
�多了也会引入更多本可以避免的复杂度。

是可以推断出来的，我前面的回复已经说了，你可以仔细对��
�一下那三个文件
