SpringBoot学习记录3------外部配置文件yml

先看一个最简单的例子：

person:
  name: LJK
  age: 18@ConfigurationProperties(prefix = "person")
@Component
public class MyConfig {

    private String name;
    private int age;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }
}

要用到这个配置的时候，只要简单的

@Autowired
private MyConfig myConfig;
