spring怎么后台注入数据？

3种方法 1。构造器注入 public class xx { private Manager manage; public xx(Manager manage){ this.manage= manage; } } 2.setter 方法注入 public class xx { private Manager manage; public void setManager(Manager manage){ this.manage= manage; } } 3.接口注入 public interface Manager{ public void manage(Business business); } public class xx { private Business business; public void manage(Business business){ this.business = business; } }
