使用kryo作为spring data redis的序列化器

kryo是个高性能的序列化器，目前无人能出其右。

<bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
<property name="hostName" value="localhost"/>
<property name="port" value="6379"/>
<property name="password" value="asdf"/>
<property name="timeout" value="2000"/>
<property name="usePool" value="true"/>
</bean>

<bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
<property name="connectionFactory" ref="jedisConnectionFactory"/>
<property name="defaultSerializer">
<bean class="com.skmbw.yinlei.redis.KryoRedisSerializer"/>
</property>
<property name="keySerializer">
<bean class="org.springframework.data.redis.serializer.StringRedisSerializer"/>
</property>
</bean>

KryoRedisSerializer实现，kryo是非线程安全的，每个现成要使用自己的kryo。

public class KryoRedisSerializer<T> implements RedisSerializer<T> {
private Kryo kryo = new Kryo();

@Override
public byte[] serialize(Object t) throws SerializationException {
byte[] buffer = new byte[2048];
Output output = new Output(buffer);
kryo.writeClassAndObject(output, t);
return output.toBytes();
}

@Override
public T deserialize(byte[] bytes) throws SerializationException {
Input input = new Input(bytes);
@SuppressWarnings("unchecked")
T t = (T) kryo.readClassAndObject(input);
return t;
}

}
