Spring依賴注入三種實現方式

1.構造函數注入(通過構造函數的參數注入)

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