Use ehcache to storage MethodAccess occured NotSerializableException #49

Closed qianzhiheilv closed 8 years ago

qianzhiheilv commented 8 years ago

EntityMethodAccess is created by ReflectASM,I think it should implements Seriablizable

I don't see any thing Kryo related here.

qianzhiheilv commented 8 years ago

I used ehcache to cache the MethodAccess and Instance to improve efficiency，It is not Kryo,It is ehcache.

NathanSweet commented 8 years ago

Oh right, this repo is Reflectasm, not Kryo, sorry. The stacktrace shows ObjectOutputStream is being used, which is Java's native serialization, and it can't write EntityMethodAccess. I don't think we'll make MethodAccess Serializable. You can wrap it in your own class that is Serializable though.

Actually,My class Entity is already Serializable,My Entity is extend JSONObject and JSONObject extends JSON implements Map<String, Object>, JSONAware, Cloneable, Serializable, InvocationHandler. If I use ehcache to cache Entity or Class of Entity directly ,It is successful.

qianzhiheilv commented 8 years ago

I changed the source code to implement Serializable,It cache successfully
