SpringBoot属性配置-第三章

1.application.yml配置
#自定义参数对象
book:
  name: A
  id: 1
  page:  100

2.创建实体类：

/**
 * @Auther: youqc
 * @Date: 2018/4/7 16:36
 * @Description:
 */
@Component
@ConfigurationProperties(prefix = "book")
public class Book {
    private Integer id;
    private String name;
    private Integer page;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

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

    public Integer getPage() {
        return page;
    }

    public void setPage(Integer page) {
        this.page = page;
    }
}

3.创建Controller类

/**
 * @Auther: youqc
 * @Date: 2018/4/7 16:38
 * @Description:
 */
@RestController
public class BookController {

    @Autowired Book book;
    @RequestMapping(value = "/getInfo",method = RequestMethod.GET)
    public String getBookInfo(){
        return "bookInfo:  id="+book.getId()+",name="+book.getName()+",Page="+book.getPage();
    }
}
访问结果：
