SpringBoot如何从配置文件中读取配置参数

# 接口请求基础路径
base.param.url = http://192.168.1.110:18081/interaction/v1/
# 平台标识
base.param.platformID = 123456789
# 平台密钥
base.param.platformSecret = AaBbCcDd

@Value("${base.param.url}")
private String baseUrl;
 
@Value("${base.param.platformID}")
private String platformID;
 
@Value("${base.param.platformSecret}")
private String platformSecret;

@Component
public class Common {
 
    private static String platformID;
 
    @Value("${base.param.platformID}")
    public void setPlatformID(String platformID) {
        Common.platformID = platformID;
    }
}

<!--使用xml或properties配置所依赖的包 @PropertySource-->
