java - 在 Virtual Box 上为 Spring Boot 应用程序运行 WAR 时出错

Question

我正在尝试在 Virtual Box 上运行由 MongoDB 和 Redis Server 组成的 Spring Boot 应用程序，但出现与 redis 相关的错误，因此无法完成该过程..我收到这些错误:

我尝试了以下但没有成功:

Answer 1

看起来像是连接问题，请验证以下内容:

配置不匹配

在您的 redis redis.conf 文件中找到绑定(bind)配置和默认端口

bind 127.0.0.1
port 6379

JedisConnectionFactory 使用的 jedis 默认值(查看您的堆栈跟踪)是:

bind localhost
port 6379

查看jedis客户端Protocol和 Spring 数据 JedisConnectionFactory类。

确保它们与您的 spring-boot 应用程序配置相匹配如果不使用 JedisShardInfo要更新您的配置，JedisConnectionFactory 在其构造函数中接受 JedisShardInfo。

确保您的/etc/hosts 或 c:\windows\system32\drivers\etc\hosts有条目

127.0.0.1       localhost

尽管有些琐碎，但有时有人会更改或删除它。

Redis 启动失败

确保您的 redis 已启动并正在运行，也许其他进程正在使用 redis 端口。使用

netstat –anp | grep 6379

或 window

netstat –ano | find “6379”

如果发现其他进程使用该端口，则相应调整
