@Dreamlu 恩,这种是没问题的,但是我再获取此key(Redis.use().get("OnlyTest"))的时候就会报错:java.lang.RuntimeException: java.io.IOException: java.lang.NullPointerException at com.jfinal.plugin.redis.serializer.FstSerializer.valueFromBytes(FstSerializer.java:78) at com.jfinal.plugin.redis.Cache.valueFromBytes(Cache.java:1211)
