工厂方法需要时个静态方法呢

@wendal
那我如何配置一个 字符串的 list 数据 到ioc中

写个静态方法，然后返回需要的对象

@wendal
单独list没戏啦

来自 iPhone 6

@Rekoe 肯定可以啊，待我写段demo。代码给你

@wendal 好

来自 iPhone 6


		array : {
			type : "java.util.ArrayList",
			args : [["wendal", "zozoh", "pangwu"]]
		}

读取

System.out.println(ioc.get(List.class, "array").toString());

输出

[wendal, zozoh, pangwu]

@wendal
为啥我的报这个错误

额，aop

你配置了某些泛指的aop？

继承ArrayList做个类吧

@wendal
$aop : { type : 'org.nutz.ioc.aop.config.impl.JsonAopConfigration', fields : { itemList : [ [ '.+', 'toString', 'ioc:log' ], [ 'com\\.rekoe\\.msg\\.handler\\..+', '(doHandler)+','ioc:msgHadhler' ], [ 'com\\.rekoe\\.db\\.service\\.impl\\..+', '(update)+','ioc:txREPEATABLE_READ' ], ] } }

@wendal
去掉那个日志的aop了
