spring依赖注入的三种方式

1.接口注入

2.getter,setter注入

3.构造器注入

1.接口注入

2.setter注入

     <bean id="book" class="com.PRoperty.Book">		<property name="bookName" value="java核心技术"></property>     </bean> 
package com.property;public class Book {	private String bookName;		public void setbookName(String bookName){		this.bookName = bookName;	}		public void demoBook(){		System.out.println("..........."+this.bookName);	}}3.构造器注入
package com.property;public class Property {	private String name;	public Property(String name){		this.name = name;	}	public void test(){		System.out.println("............."+name);	}	}
     <bean id="property" class="com.chen.property.Property">         <constructor-arg name="name" value="java">               </constructor-arg>     </bean>或者是
     <bean id="property" class="com.property.Property">         <constructor-arg index="0" value="java" >               </constructor-arg>              </bean>
接口注入
