Enum serilization issue #19

Closed apotapov closed 10 years ago

apotapov commented 10 years ago

I have the following enum that serves as a field on a hibernate entity:

package com.bvg.models.enums;

public enum Gender {
    MALE,
    FEMALE
}

Entity:

@Entity
@Table(name = "users")
@Getter
@Setter
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
public class User extends AbstractModel implements Subject {
...
@Enumerated(EnumType.STRING)
    @Column
    protected Gender gender;
...
}

I have configured hibernate-redis as per instructions, and things seem to work fine for entities that use primitive types for fields (String, int, boolean, etc) However, this enum is giving me trouble. Do I need to register it with the serializer somehow? Seems like it should be able to handle an enum.

Here's the stack trace that i get:

Well... try test enumerated entity example

debop commented 10 years ago

Oh! hibernate-redis use Fast-Serialization FST not support jdk 8, I guess try to use JDK 6 or JDK 7

apotapov commented 10 years ago

But lambda functions are so sexy!

I'll file a bug for FST to support java 8.

RuedigerMoeller commented 10 years ago

I'd speculate its a classpath/classloader issue. This does not look like a FST error as you can see it is looking for a perfectly valid classname, but cannot load it. NOte that with 1.55 there is a setClassLoader on the FSTConfiguration in case you have to deal with custom classloaders, however this seems more like a setup problem.

apotapov commented 10 years ago

Thanks for looking into it. I would prefer not to roll my own classloader for this purpose.

I filed a bug with FST. I will try to get a reproducible test for FST and hopefully we can figure out the issue. I'll keep you posted.

apotapov commented 10 years ago

This has nothing to do with Java 8 after all. Looks like this is an issue with Playframework and their classloaders:

playframework/playframework#2847

Apologies for the confusion.
