Spring Boot如何读取自定义外部属性详解

public class People {
    private String name;
    private String address;
    private String phone;
}

    @Autowired
    private People people;

    @RequestMapping("/test1")
    public void test1(){
        System.out.println(people);
    }
}

@Data
//@Setter
@ToString
@Configuration
@ConfigurationProperties(prefix = "people.default")
