YML文件_yml 文件-优快云博客

文章讨论了在SpringBoot项目中如何正确读取YML配置文件，包括application.yml加载其他yml文件，使用@ConfigurationProperties注解绑定配置属性。在测试案例中，展示了bookorder对象的初始化，但测试结果显示time字段为null，可能存在配置解析问题。

YML文件读取

yml key 和value 之間必須有一個空格

SpringBoot通過
@Value(“${upload.path}”) 或者
@ConfigurationProperties(prefix = “upload”)
讀取不到value

upload:
path:X d:/upload

application.yml加载其它yml文件

spring:
  profiles:
    include: 'order'

定义application-order.yml

bookorder:
  orderID: ${random.int}
  orderName: "TSL order bill"
  des: "a good car"
  time:
    type: DateTime<'Y-m-d H:i:s'>
    groups: [detailed]
  buyer:
    - id: 1
      name: Claire
    - id: 2
      name: Jeff

@component && @ConfigurationProperties(prefix=“bookorder”)

@Data
@Component
@Slf4j 
@Builder
@AllArgsConstructor
@NoArgsConstructor
@JsonPropertyOrder(value= {"time","orderName"})
@ConfigurationProperties(prefix="bookorder")
public class Order {
	//@JsonIgnore
	public long orderID;
	public String orderName;
	public String des;
	@JsonFormat(shape = JsonFormat.Shape.STRING, 
	pattern = "yyyy-MM-dd hh:mm:ss", timezone = "GMT+8")
	public Date time;
	//@JsonProperty("buy")
	//@JsonInclude(JsonInclude.Include.NON_NULL)
	public List<Buyer> buyer;
}

测试Case

@SpringBootTest
@Slf4j
class OrderInitiationTest {

	@Resource
	Order order;
	
	@Test
	void test() {
		log.info(order.toString());
	}

}

测试结果

Order(orderID=-1804440514, orderName=TSL order bill, 
des=a good car, time=null, 
buyer=[Buyer(id=1, name=Claire), Buyer(id=2, name=Jeff)])
