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"

</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>
<!-- <aop:scoped-proxy/> -->
</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:
/**
*
* <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:
<!-- 添加下面,一行,每次创建的,都是一个代理对象,然后注入获取的都是新的对象 -->
<aop:scoped-proxy/>
测试结果:
