spring如何使用xml装配bean

package soundsystem;
public class Dog {
private String Cry;//叫声
//用setter方法注入
public void setCry(String cry) {
  Cry = cry;
}
//定义一个狗叫方法
  public void DogCry(){
    System.out.println("狗叫："+Cry);
    Cat.CatCry();
    catEat.CatEating();
  }
}

package soundsystem;
public class Cat {
  private String Cry;//叫声

//用构造函数注入
  public Cat(String cry){
    this.Cry=cry;
  }

//定义一个猫叫方法
  public void CatCry(){
    System.out.println("猫叫："+Cry);
  }
}

<&＃63;xml version="1.0" encoding="UTF-8"&＃63;>

  }
}
