问题原因:pom.xml中引入的两个redis相关jar不兼容.

<!--Spring整合redis包 --><dependency><groupId>org.springframework.data</groupId><artifactId>spring-data-redis</artifactId><version>2.1.3.RELEASE</version></dependency><dependency><groupId>redis.clients</groupId><artifactId>jedis</artifactId><version>3.0.0</version></dependency>

解决办法:降低redis.clients的版本:

<!--Spring整合redis包 --><dependency><groupId>org.springframework.data</groupId><artifactId>spring-data-redis</artifactId><version>2.1.3.RELEASE</version></dependency><!-- https://mvnrepository.com/artifact/redis.clients/jedis --><!-- https://mvnrepository.com/artifact/redis.clients/jedis --><dependency><groupId>redis.clients</groupId><artifactId>jedis</artifactId><version>2.9.1</version></dependency>

希望对你有所帮助:
