SpringBoot通過@Value獲取application.yml配置文件的屬性值

application.yml實例：

spring: redis: database: 0 host: 127.0.0.1

獲取方法：

/** * @Auther:WangZiBin * @Description: * @Modified By: */ @Configuration public class JedisConfig{ private Logger jedisConfigLogger= LoggerFactory.getLogger(JedisConfig.class); @Value("${spring.redis.host:#{null}}") private String host; @Value("${spring.redis.port:#{null}}") private Integer port; public String getHost() { return host; } public void setHost(String host) { this.host = host; } public Integer getPort() { return port; } public void setPort(Integer port) { this.port = port; } }

注意@Configuration注解是必須的，@Component同樣適用

@Value("${spring.redis.port:#{null}}")

其中

:#{null}

作用為在取不到對應配置值時，采用默認值null賦值
