Spring依赖注入三种实现方式

1.构造函数注入(通过构造函数的参数注入)

class Solution{
	private Student student;
	public Solution(Student student){
		this.student=student;
	}
	public static void main(String[]args){
		
	}
}

2.setter方法注入

class Solution{
	private Student student;
	public void setStudent(Student student){
		this.student=student;
	}
	public static void main(String[]args){
		
	}
}

3.接口注入

public interface Dependence{
           void SetDependence(Student student);//设置依赖
}
class Solution implements Dependence{
	private Student student;
	public void SetDependence(Student student){
		this.student=student;
	}
	public static void main(String[]args){
		
	}
}
