Spring注解疑问，谢谢，@Autowired 注释private List as;就自动绑定到a所有的实现类到List没有,谢谢

下面代码无法依赖注入实际的类，请各位大神能否帮忙看看，谢谢，测试代码如下:
public interface HelloBeanInf {
public void test();
}
然后两个实现类
@Service
public class HelloBean implements HelloBeanInf{
private String helloWord = "ssss";

public void test(){
System.out.println(helloWord);
}
}


@Service
public class HelloBean1 implements HelloBeanInf{
private String helloWord = "aaaaa";

public void test(){
System.out.println(helloWord);
}
}
配置文件
bean.xml
<context:annotation-config/>

主类进行调用的
public class SpringTest {

private HelloBeanInf helloBean;

@Autowired
private HelloBeanInf[] helloBeanInfs;//List<HelloBeanInf> helloBeanInfs;

public HelloBeanInf[] getHelloBeanInfs() {
return helloBeanInfs;
}


public void setHelloBeanInfs(HelloBeanInf[] helloBeanInfs) {
this.helloBeanInfs = helloBeanInfs;
}

public static void main(String[] args) {
// TODO Auto-generated method stub
org.springframework.core.io.Resource res = new ClassPathResource("com/cec/bean.xml");
BeanFactory factory = new XmlBeanFactory(res);
SpringTest springTest = new SpringTest();
for (HelloBeanInf t : springTest.getHelloBeanInfs()) {
((HelloBeanInf) t).test();
}

}

报null,依赖没有注入，请问是什么原因没有注入呢，谢谢

org.springframework.core.io.Resource res = new ClassPathResource("com/cec/bean.xml"); BeanFactory factory = new XmlBeanFactory(res); SpringTest springTest = new SpringTest(); 这样new出来有什么用？

解决办法： 第一步 @service("springTest") public class SpringTest { 第二步： ApplicationContext res = new FileSystemXmlApplicationContext( "com/cec/bean.xml"); Test springTest = (Test) res.getBean("springTest") for (HelloBeanInf t : springTest.getHelloBeanInfs()) { ((HelloBeanInf) t).test(); }
