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();

   }
