实际上有两个问题。
1）如何在spring mvc 3中使用@autowired注释替换下面的代码，我希望将动态值从控制器类传递给构造函数参数。
EncDec lEncDec = (EncDec) context.getBean("encDec", new Object[]{EncDec.getMD5Hash(Id)});
normal java code would be EncDec lEncDec = new EncDec(EncDec.getMD5Hash(Id))
2）@service和@repository抛出异常之间我声明它们工作正常但我想从xml中删除依赖
org.springframework.beans.factory.BeanCreationException: Error creating bean with name
我在dispatch-servlet.xml中声明了我的类
<context:component-scan base-package="com.controller,com.serviceimpl,com.daoimpl" />
Please see this mkyong example for question 2
