Spring Bean装配之Autowired注解说明-2

1.使用

2.数组及Map的自动注入：

package com.wuyonghu.autowired;

public interface BeanInterface {

}

package com.wuyonghu.autowired;

import org.springframework.stereotype.Component;

@Component
public class BeanImpl1  implements BeanInterface{

}

package com.wuyonghu.autowired;

import org.springframework.stereotype.Component;

@Component
public class BeanImpl2  implements BeanInterface{

}

package com.wuyonghu.autowired;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Component
public class BeanInvoker {

    @Autowired
    private List list;

    public void say(){
        if(null!=list){
            for (BeanInterface bean : list) {
                System.out.println(bean.getClass().getName());
            }
        }else{
            System.out.println("自动注入失败");
        }
    }
}

测试代码：

@Test
    public void testHello7() {
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
        BeanInvoker resources = (BeanInvoker) context.getBean("beanInvoker");
        resources.say();
    }
