springboot中使用spring-data-redis出现Caused by: java.lang.ClassNotFoundException: redis.clients.jedis.JedisPoolConfig
在maven的配置如下：
<dependency>
? ?<groupId>org.springframework.boot</groupId>
? ?<artifactId>spring-boot-starter-data-redis</artifactId>
? ?<version>2.0.4.RELEASE</version>
?</dependency> ??启动测试类的时候，总是出现如下异常；

修改成如下配置：
<dependency>
? <groupId>org.springframework.boot</groupId>
? <artifactId>spring-boot-starter-data-redis</artifactId>
? <exclusions>
??? <exclusion>
??? ?<groupId>io.lettuce</groupId>
??? ?<artifactId>lettuce-core</artifactId>
??? </exclusion>
? </exclusions>??? ??? ????
</dependency>??? ????
<dependency>
? <groupId>redis.clients</groupId>
? <artifactId>jedis</artifactId>
</dependency>?为什么？看友人翻译
JedisPoolConfig?is needed when we use?Jedis?Configuration. In Spring Boot 2.0,?spring-boot-starter-data-redis?gives?Lettuce?dependency by default instead of?Jedis. To use?Jedis?configuration, exclude?Lettuce?and add?Jedis?as following.
