我试图通过我的spring mvc应用程序连接redis进行会话存储 . 我使用Lettuce作为redis客户端 . 这样做时,我遇到一个错误说明..

NoClassDefFoundError: com/lamdaworks/redis/protocol/CommandEncoder at org.springframework.session.data.redis.RedisOperationSessionRepository$RedisSession.saveDelta(RedisOperationSessionRepository.java:788)

当我使用 jedis client api时,同样的工作正常 .

注意:我没有使用像maven这样的构建工具 . 我已经下载了独立的 jar . 以下是列表和版本

lettuce-3.5.0.Final.jar (也是https://mvnrepository.com/artifact/biz.paluch.redis/lettuce/3.5.0.Final中提到的所有支持 jar )

Spring-data-redis-1.7.1.release.jar

我的app-config.xml如下

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
