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
">
<bean>
<property ref="prototype"></property>
</bean>
<bean scope="prototype">
<property value="刘东"></property>
<property value="123"></property>
<!-- <aop:scoped-proxy/> -->
</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:
