Spring 注解实例--@Autowired 注入到List和Map

package com.Autowired.ListMap;

import org.springframework.core.annotation.Order;
import org.springframework.stereotype.Component;
/**
 * order：把实现类排序输出 只适合List
 * @author liu
 *
 */
@Order(2)
@Component
public class BeanImplOne implements BeanInterface {

}

================================

package com.Autowired.ListMap;

import org.springframework.core.annotation.Order;
import org.springframework.stereotype.Component;

@Order(1)
@Component
public class BeanImplTwo implements BeanInterface {

}

=====================================

BeanInterface只是一个接口无方法

======================================

package com.Autowired.ListMap;

import java.util.List;
import java.util.Map;


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

@Component
public class BeanInvoke {
	
	@Autowired
      private List list;
      
    @Autowired
    private Map map;
    
    /** @Autowired默认为byType的  所以有两个相同类型的bean  
     * 如果不使用 @Qualifier指定具体的bean就会抛出异常
     *  private BeanInterface beaninterface;
     */
    @Autowired
   @Qualifier("beanImplOne")
    private BeanInterface beaninterface;
	public void say(){
		System.out.println("list...");
		if(null !=list &&0!=list.size()){
			for(BeanInterface bean :list){
				System.out.println(bean.getClass().getName());
			}
			
		}else{
			System.out.println("List list is null !!!!");
		}
		System.out.println();
		System.out.println("map...");
		if(null !=map &&0!=map.size()){
			for(Map.Entry m:map.entrySet()){
				  System.out.println(m.getKey()+"    "+m.getValue().getClass().getName());
			}
		}else{
			System.out.println("Map map is null !!!!");

		}
		System.out.println("-------------------------");
		if(null !=beaninterface){
			System.out.println(beaninterface.getClass().getName());
		}else{
			System.out.println("beaninterface is null !!!");
		}
	}
	
	
}

测试类：

package com.Autowired.ListMap;

import org.junit.Test;

import com.imooc.test.base.UnitTestBase;


public class TestListMap  extends UnitTestBase{
    public TestListMap(){
    	super("classpath*:spring-beanannotation3.xml");
    }
    
    @Test
    public void test(){
    	BeanInvoke  bean=super.getBean("beanInvoke");
    	bean.say();
    }
}
