10 import org.springframework.beans.BeansException;

21 @Configuration
22 public class Car {
23     private String brand;
24     private String color;
25     private int maxSpeed;
26     
27     private List abc = new ArrayList();

29     private Properties mail = new Properties();

31     private Boss boss;
32     @Scope("prototype")
33     @Bean
34     public Boss getBoss() {
35         return boss;
36     }
37     public void setBoss(Boss boss) {
38         this.boss = boss;
39     }

44         this.mail = mail;
45     }
46     public Map getMap() {
47         return map;
48     }
49     public void setMap(Map map) {
50         this.map = map;
51     }
52     public List getAbc() {
53         return abc;
54     }
55     public void setAbc(List abc) {
56         this.abc = abc;
57     }
58     public String getBrand() {
59         return brand;
60     }
61     public void setBrand(String brand) {
62         this.brand = brand;
63     }
64     public String getColor() {
65         return color;
66     }
67     public void setColor(String color) {
68         this.color = color;
69     }
70     public int getMaxSpeed() {
71         return maxSpeed;
72     }
73     public void setMaxSpeed(int maxSpeed) {
74         this.maxSpeed = maxSpeed;
75     }
76 
77 
78 }

@Configuration 相当于 @@Component

@Scope 定义bean的作用域

用

AnnotationConfigApplicationContext启动注解类

1     ApplicationContext ctx = new AnnotationConfigApplicationContext(Car.class);
2         Car car = ctx.getBean(Car.class);
           ctx.register(Boss.class); //注册多个@Configuration的配置类
3         System.out.println(car.getBoss());
