问题原因:pom.xml中引入的两个redis相关jar不兼容.

		
		
			org.springframework.data
			spring-data-redis
			2.1.3.RELEASE
		
		
			redis.clients
			jedis
			3.0.0
		

解决办法:降低redis.clients的版本:

		
		
			org.springframework.data
			spring-data-redis
			2.1.3.RELEASE
		
		
		
		
			redis.clients
			jedis
			2.9.1
		

希望对你有所帮助:
