回答: 这个错误是由于缺少redis.clients.jedis.ConnectionPoolConfig类引起的。根据引用\[1\],可能是由于缺少redis.clients.jedis.UnifiedJedis类导致的。解决这个问题的方法有两种。一种是根据引用\[2\],在项目的pom文件中排除lettuce-core依赖,然后添加jedis依赖。另一种是根据引用\[3\],检查项目中的redis和springboot版本是否冲突,如果有冲突,可以尝试升级或降级其中一个版本以解决冲突。

这个错误信息表明在运行时没有找到 com.venustech.ca.system.model.SoftwareUpgradeBO 类。这可能是由于类路径问题,即缺少类文件或类文件不在正确的位置。也可能是由于该类所在的 jar 包没有被正确加载。您可以检查类路径和 jar 包加载是否正确,以解决这个问题。
