Got String instead of the desired Pojo Type I need after deserialization

[Tsin Yi]

       @David Yu:

           When I tried to deserialize bytes from Redis(the Serializer works just fine), I got String instead of the desired Pojo Type I need after deserialization, the following is my custom serializer(implements RedisSerializer) :

          (And by the way ,how to allocate a proper size of the LinkedBuffer)

      Much Thanks!

Can you provide a simple example that I can replicate?

If multiple threads are accessing that method concurrently, your instance field "buffer" will cause problems.

So what you would do is use ThreadLocal to store a reference and use that.

    /**

     * Local serialization buffer for each thread 

     */ 

    static final ThreadLocal<LinkedBuffer> LOCAL_BUFFER = new ThreadLocal<LinkedBuffer>() { 

        @Override 

        protected LinkedBuffer initialValue() { 

            return LinkedBuffer.allocate(8192); 

        } 

    }; 

// usage

LinkedBuffer lb = LOCAL_BUFFER.get();

      Much Thanks!
