Spring data redis Failed to deserialize object type; The nested exception is java.lang.ClassNotFoundException

I am using spring-data-redis 1.1.0 and jedis 2.1.0.

When I deploy my code to Karaf, I get the following exception:

Is the byte array a result of corresponding serialization for DefaultDeserializer?; nested exception is org.springframework.core.NestedIOException: Failed to deserialize object type; nested exception is java.lang.ClassNotFoundException

It works when I start JUnit.

Below is my redisTemplate.

<bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
