hi team,
Please kindly advise.
Below is my code and exception.
Btw, if I use ScanQuery<String, Object> and List, no error.
Something wrong with classloader? the normal cache put and get work well for
my class, data could be deserialised to my class automatically.
thank you
My code:
*******************************************************************************
cache.put(ProjectCacheConst.STATION_PREFIX+"1", new StationDto());
cache.put(ProjectCacheConst.STATION_PREFIX+"2", new StationDto());
cache.put(ProjectCacheConst.STATION_PREFIX+"3", new StationDto());
ScanQuery<String, StationDto> scanQuery = new ScanQuery<>(
(k, v) -> k.startsWith(ProjectCacheConst.STATION_PREFIX) &&
nonNull(v));
List<StationDto> list = getCache(projectCode).query(scanQuery,
Cache.Entry::getValue).getAll();
*******************************************************************************
