dubbo 3.0.5 没有这样的问题！

通过查看源码做如下配置，修改他的缓存存储目录 dubbo.mapping.cache.filePath
下面这段是源码 public MappingCacheManager(String name, ScheduledExecutorService executorService) { String filePath = System.getProperty("dubbo.mapping.cache.filePath"); String fileName = System.getProperty("dubbo.mapping.cache.fileName"); if (StringUtils.isEmpty(fileName)) { fileName = DEFAULT_FILE_NAME; }
if (StringUtils.isNotEmpty(name)) { fileName = fileName + "." + name; } String rawEntrySize = System.getProperty("dubbo.mapping.cache.entrySize"); int entrySize = StringUtils.parseInteger(rawEntrySize); entrySize = (entrySize == 0 ? DEFAULT_ENTRY_SIZE : entrySize); String rawMaxFileSize = System.getProperty("dubbo.mapping.cache.maxFileSize"); long maxFileSize = StringUtils.parseLong(rawMaxFileSize); init(filePath, fileName, entrySize, maxFileSize, 50, executorService);}
