Spring Boot使用Value注解给静态变量赋值的方法

@Component
public class CoverImageUtil {

  private static String endpoint;

  private static String bucketName;

  @Value("${oss.endpoint}")
  private void setEndpoint(String name){
    endpoint = name;
  }
  @Value("${oss.bucketName}")
  private void setBucketName(String name){
    bucketName = name;
  }
  public static String getImage(String path){

    if (StringUtils.isEmpty(path)){
      return null;
    }
    // XXX的图片地址 https://oss.XXX.com/uploads/8F/70/8F70879210F08AAA6F4A04A3D42F3704.jpg
    if (path.contains("oss.XXX.com")){
      return path;
    }
    String[] str = path.split(",");

    // mt的图片地址
    // key = customer/coverImg/1002,FAFA5EFEAF3CBE3B23B2748D13E629A1,418530,image/jpeg
    // url = https://m-t-tesing.oss-cn-hangzhou.aliyuncs.com/customer/coverImg/1002
    StringBuilder url = new StringBuilder("https://");
    url.append(bucketName)
        .append(".")
        .append(endpoint)
        .append("/")
        .append(str[0]);

    return url.toString();
  }
}
