错误：java.lang.NullPointerException: Cannot invoke “Object.toString()” because “temp” is null
at com.example.emos.wx.service.impl.MeetingServiceImpl.searchRoomIdByUUID(MeetingServiceImpl.java:200)
at com.example.emos.wx.controller.MeetingController.searchRoomIdByUUID(MeetingController.java:147)
at com.example.emos.wx.controller.MeetingController $F a s t C l a s s B y S p r i n g C G L I B$ abe39e21.invoke()

报错的代码

public Long searchRoomIdByUUID(String uuid) {
    Object temp = redisTemplate.opsForValue().get(uuid);
    long roomId = Long.parseLong(temp.toString());
    return roomId;
}
