Multiple bean injection in spring singleton bean

Problem:

When injecting a multi-instance bean into a singleton bean, it is not getting to that multi-sample object, because, when the singleton is initialized, it is initialized directly, and this multi-instance bean is always getting the first initialized bean.

Configuration file:

<?xml version= "1.0" encoding= "UTF-8"?> <beans xmlns= "Http://www.springframework.org/schema/beans" Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance" xmlns:aop= "HTTP://WWW.SPRINGFRAMEWORK.ORG/SCHEMA/AOP" Xsi:schemalocation= "Http://www.springframework.org/schema/beans Http://www.springframework.org/schema/beans/spring-beans.xsd Http://www.springframework.org/schema/aop Http://www.springframework.org/schema/aop/spring-aop.xsd "> <bean id= "single" class= "Com.lzd.spring.context.resource.test.bean.SingletonObject" > <property name= "Prototypeobject" ref= "prototype" ></property> </bean> <bean id= "prototype" class= "Com.lzd.spring.context.resource.test.bean.PrototypeObject" scope= "prototype" > <property name= "name" value= "Dong Dong" ></property> <property name= "password" value= "123" ></property> <!--<aop:scoped-proxy/> -- </bean> </beans>

Singletonobject object:

Package Com.lzd.spring.context.resource.test.bean; public class Singletonobject { Private Prototypeobject prototype; public void Setprototypeobject (Prototypeobject prototype) { This.prototype = prototype; } Public Prototypeobject Getprototype () { return this.prototype; } }

Prototypeobject object:

package Com.lzd.spring.context.resource.test.bean; /**  *  * <p>description: This is a multi-instance object </p>  * @ClassName: Prototypeobject  * @author lzd  February 15, 2017 morning 10:54:52  */ public class Prototypeobject {     private String name;     private String password;          public String getName () {          return name;     }     public void SetName (String name) {         this.name = name;     }     public String GetPassword () {          return password;     }     public void SetPassword (String password) {          This.password = password;     } }

Applicationresourcetest Test class:

Package com.lzd.spring.context.resource.test; Import Org.junit.Test; Import Org.springframework.context.ApplicationContext; Import Org.springframework.context.support.ClassPathXmlApplicationContext; Import Com.lzd.spring.context.resource.test.bean.SingletonObject; public class Applicationresourcetest { @Test public void Applicationresource () { ApplicationContext context = new Classpathxmlapplicationcontext (new string[]{"Classpath:application.xml"}); Singletonobject s = (singletonobject) Context.getbean ("single"); for (int i = 0; i <; i++) System.out.println (S.getprototype ()); } }
