Spring 依赖注入有哪几种方式

/*带参数，方便利用构造器进行注入*/   public CatDaoImpl(String message){           
    this. message = message;   
}  
<bean id="CatDaoImpl" class="com.CatDaoImpl">   
    <constructor-arg value=" message "></constructor-arg>   
</bean> 复制代码

 public class Id {   
     private int id;   
     public int getId() {   
         return id;  
     }    
     public void setId(int id) {  
         this.id = id;   
     }   
}  
<bean id="id" class="com.id ">  
    <property name="id" value="123"></property>  
</bean>   复制代码

public class DaoFactory {   
    //静态工厂       
    public static final FactoryDao getStaticFactoryDaoImpl(){           
        return new StaticFacotryDaoImpl();   
    }   
}   
public class SpringAction {             
    private FactoryDao staticFactoryDao;  //注入对象   
    //注入对象的 set 方法   
    public void setStaticFactoryDao(FactoryDao staticFactoryDao) {           
        this.staticFactoryDao = staticFactoryDao;   
    }
}   
//factory-method="getStaticFactoryDaoImpl"指定调用哪个工厂方法
<bean name="springAction" class=" SpringAction" >   
    <!--使用静态工厂的方法注入对象,对应下面的配置文件-->   
    <property name="staticFactoryDao" ref="staticFactoryDao"></property>             
</bean>   
<!--此处获取对象的方式是从工厂类中获取静态方法-->   
<bean name="staticFactoryDao" class="DaoFactory" factory-method="getStaticFactoryDaoImpl"></bean> 复制代码
