默认@Bean是单例的，但可以使用@Scope注解来覆盖此如下：

@Configurationpublic class MyConfiguration {	@Bean	@Scope("prototype")	public MovieCatalog movieCatalog(){		//...	}}

 Bean的作用域包括singleton、prototype、request、session、global session

例子：

 新建接口Store及实现类StoreImpl

package com.scope;public interface Store {}

 

package com.scope;public class StoreImpl implements Store {	}

 java config 实现

package com.scope;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.context.annotation.Scope;@Configurationpublic class StoreConfig {	@Bean	@Scope("prototype")	public Store stringStore(){		return new StoreImpl();	}}

 XML配置：

 单元测试：

package com.scope;import org.junit.Test;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;public class UnitTest {		@Test	public void test(){		ApplicationContext context = new ClassPathXmlApplicationContext("classpath:spring-beanannotation.xml");  		Store store=(Store)context.getBean("stringStore");		System.out.println(store.hashCode());				Store store2=(Store)context.getBean("stringStore");		System.out.println(store2.hashCode());			}}

 结果：

2015-7-8 9:47:11 org.springframework.context.support.ClassPathXmlApplicationContext prepareRefresh信息: Refreshing org.springframework.context.support.ClassPathXmlApplicationContext@36b8bef7: startup date [Wed Jul 08 09:47:11 CST 2015]; root of context hierarchy2015-7-8 9:47:11 org.springframework.beans.factory.xml.XmlBeanDefinitionReader loadBeanDefinitions信息: Loading XML bean definitions from class path resource [spring-beanannotation.xml]1152423575628012732

结果发现，两个对象的hashcode不一样，说明每次取出的都是新的对象。
