1、类A中有成员变量类B,类B使用@Autowired注解的方式注入A中。
2、类B实现了接口IB.
问题：
启动时报错：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'a':
Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException:
Could not autowire field: com.siqisoft.test.B com.siqisoft.test.A.b;
nested exception is java.lang.IllegalArgumentException:
Can not set com.siqisoft.test.B field com.siqisoft.test.A.b to $Proxy23
疑问：
为什么实现了接口的B不能被注入到A中呢？
类A:
package com.siqisoft.test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
@Component
public class A {
@Autowired
B b;
}
类B:
package com.siqisoft.test;
import org.springframework.stereotype.Component;
@Component
public class B {
public void BMethod(){};
}
B实现的接口
package com.siqisoft.test;
public abstract interface IB {
}
