默认@Bean是单例的，使用@Scope指定它的范围：

package com.imooc.beanannotation.javabased;//import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;
import org.springframework.context.annotation.Scope;@Configuration
@ImportResource("classpath:config.xml")
public class StoreConfig {/*@Value("${url}")private String url;@Value("${jdbc.username}")private String username;@Value("${password}")private String password;@Beanpublic MyDriverManager myDriverManager(){return new MyDriverManager(url,username,password);}*//*@Bean(name="stringStore",initMethod="init",destroyMethod="destroy")public Store stringStore(){return new StringStore();}*/@Bean(name="stringStore"/*,initMethod="init",destroyMethod="destroy"*/)@Scope(value="prototype")public Store stringStore(){return new StringStore();}
}

package com.imooc.test.beanannotation;import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.BlockJUnit4ClassRunner;import com.imooc.beanannotation.javabased.MyDriverManager;
import com.imooc.beanannotation.javabased.Store;
import com.imooc.ioc.interfaces.UnitTestBase;@RunWith(BlockJUnit4ClassRunner.class)
public class TestJavabased extends UnitTestBase {public TestJavabased(){super("classpath*:spring-beanannotation.xml");
}@Testpublic void test(){Store store=super.getBean("stringStore");System.out.println(store.getClass().getName());;}@Testpublic void testMyDriverManager(){MyDriverManager manager=super.getBean("myDriverManager");System.out.println(manager.getClass().getName());;}@Testpublic void testScope(){Store store=super.getBean("stringStore");System.out.println(store.hashCode());store=super.getBean("stringStore");System.out.println(store.hashCode());}
}

运行结果：
