使用注解@Value映射和使用注解@ConfigurationProperties映射

person:
  name: zhangsan
  age: 18

@Controller
public class QuickStartController {
    @Value("${person.name}")
    private String name;
    @Value("${person.age}")
    private Integer age;
    @RequestMapping("/quick")
    @ResponseBody
    public String quick(){
        return "springboot 访问成功! name="+name+",age="+age;
    }
}

person:
  name: zhangsan
  age: 18

@Controller
@ConfigurationProperties(prefix = "person")
public class QuickStartController {
    private String name;
    private Integer age;
    @RequestMapping("/quick")
    @ResponseBody
    public String quick(){
        return "springboot 访问成功! name="+name+",age="+age;
    }
    public void setName(String name) {
        this.name = name;
    }
    public void setAge(Integer age) {
        this.age = age;
    }
}
