Java Redis命令超时；嵌套异常为io.莴苣.core.RedisCommandTimeoutException:命令在1分钟后超时

今天，当我使用Java redis客户端（

spring-data-redis-2.3.9.RELEASE.jar

）使用redis流消息时，遇到以下错误：

2021-05-11 17:49:42.134 ERROR 26301 --- [-post-service-1] c.d.s.p.common.mq.StreamConsumerRunner   : pull message error

一开始，客户端可以成功地使用消息，一些消息可以被正确地使用和处理，过一段时间，它将遇到超时问题。这是我的代码：

我在网上搜索，没有找到有用的建议。我已尝试将莴苣软件包版本升级到最新的

6.1.1.RELEASE

版本，但仍未修复它。问题出在哪里？我应该怎么做才能使它按预期工作？我还试着用绝地武士取代莴苣：

api ("org.springframework.boot:spring-boot-starter-data-redis") {
            exclude group: "io.lettuce", module: "lettuce-core"
}
api "redis.clients:jedis:3.6.0"

---

看来没用。

我试着用绝地武士而不是莴苣来解决这个问题

步骤1：排除生菜：

api ("org.springframework.boot:spring-boot-starter-data-redis") {
            exclude group: "io.lettuce", module: "lettuce-core"
            exclude group: "org.springframework.data", module: "spring-data-redis"
        }

由于spring boot starter数据redis同时包含

绝地

和

莴苣

，如果排除

莴苣

，默认连接应使用

绝地

api ("org.springframework.boot:spring-boot-starter-data-redis") {
            exclude group: "io.lettuce", module: "lettuce-core"
            exclude group: "org.springframework.data", module: "spring-data-redis"
        }
