Spring单例Bean中注入多例Bean

问题:

当在一个单例Bean中注入一个多例Bean的时候,是获取不到那个多例对象的,因为,单例在初始化的时候,就直接初始化,这个多例Bean啦, 一直获取的是第一次初始化的Bean

配置文件:

<?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="刘东"></property>
<property name="password" value="123"></property>

</bean>
</beans>

SingletonObject对象:

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对象:

package com.lzd.spring.context.resource.test.bean;
/**
*
* <P>Description: 这是一个多例的对象</P>
* @ClassName: PrototypeObject
* @author lzd 2017年2月15日上午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测试类:

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 < 10; i++)
System.out.println(s.getPrototype());

}

}

问题解决:

配置文件:

<aop:scoped-proxy/>
</bean>
</beans>

测试结果:
