賦值:
@Value(“true”) 直接賦值
在類中使用@Value注解獲取yml配置文件中的值時(shí),需要注意:
這種類型的值時(shí),需要用雙引號(hào)將值引起來。
比如:
錯(cuò)誤:key=0000
正確:key=“0000”
如果不使用雙引號(hào)的話,在使用@value注解時(shí),得到的值是0,而不是0000
需要使用@Autowired進(jìn)行注入,對(duì)應(yīng)類需要加上@Service
到此,相信大家對(duì)“@Value怎么獲取yml和properties配置參數(shù)”有了更深的了解,不妨來實(shí)際操作一番吧!這里是億速云網(wǎng)站,更多相關(guān)內(nèi)容可以進(jìn)入相關(guān)頻道進(jìn)行查詢,關(guān)注我們,繼續(xù)學(xué)習(xí)!
