我已经尝试了所有可以在任何地方找到的选项,我查看了之前就该主题提出的所有问题并尝试了解决方案,但没有任何效果,我得到的就是这个错误.

错误

我在这个例子中创建的文件如下.

spring.xml
这是架构定义

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;


public class Circle implements Shape{
    private Point center;

    @Override
    public void draw() {
        System.out.println("Drawing Circle");
        System.out.println("Point is : ("+center.getX()+","+center.getY()+")");
    }
    public Point getCenter() {
        return center;
    }
    @Autowired
    @Qualifier("CircleRelated")
    public void setCenter(Point center) {
        this.center = center;
    }

}
