MrLiuFang opened a new issue, #12836:
URL: https://github.com/apache/dubbo/issues/12836

   ### Environment
   
   * Dubbo version: 3.2.4
   * Operating System version: ubuntu
   * Java version: 17
   * spring boot 3.1.2
   
   ### Steps to reproduce this issue
   
   在interface 上使用@Cacheable （org.springframework.cache.annotation.Cacheable）的问题
   
   **生产者 interface：**
   ```
       @Cacheable(value = FileDefinition.CACHE_KEY_URL_MULTIPLE,key = "#tableId 
+ '-' + #fileFieldName + '-' +#tableName")
       public Map<Long,String> getUrl(@NotNull Long tableId,@NotBlank String 
fileFieldName,@NotBlank String tableName);
   ```
   
   **消费者调用方：**
   ```
   fileExposeService.getUrlSingle(1L, UserPo.TABLE_NAME, 
UserDefinition.PROFILE_PHOTO_FIELD_NAME);
   fileExposeService.getUrlSingle(2L, UserPo.TABLE_NAME, 
UserDefinition.PROFILE_PHOTO_FIELD_NAME);
   fileExposeService.getUrlSingle(3L, UserPo.TABLE_NAME, 
UserDefinition.PROFILE_PHOTO_FIELD_NAME);
   ```
   
   **在redis中缓存的数据如下：`（只有第一次远程调用可以正常缓存数据，第二，三次远程调用后的均无法正常缓存数据）`**

   ```
   第一次远程调用能产生redis key为：（urlSingle::1-t_user-profilePhoto） 的缓存
   fileExposeService.getUrlSingle(1L, UserPo.TABLE_NAME, 
UserDefinition.PROFILE_PHOTO_FIELD_NAME);
   
   第二，三次远程调用均产生了错误的redis key为：（urlSingle::null-null-null） 的缓存
   fileExposeService.getUrlSingle(2L, UserPo.TABLE_NAME, 
UserDefinition.PROFILE_PHOTO_FIELD_NAME);
   fileExposeService.getUrlSingle(3L, UserPo.TABLE_NAME, 
UserDefinition.PROFILE_PHOTO_FIELD_NAME);
   
   第二，三次远程调用产生的redis key 应为：（urlSingle::2-t_user-profilePhoto）   
（urlSingle::3-t_user-profilePhoto）
   ```
