明明都配置好了，为什么Redis连接失败

Question

问题描述：Linux虚拟机上的Redis连接失败

问题详情：此Redis服务，可以通过Redis Desktop Manager连接，但在springboot项目中却连不上。

情况如下：
springboot项目中配置：

    
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-data-redis</artifactId>
    </dependency>

    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-cache</artifactId>
    </dependency>

  data:
    redis:
      host: 192.168.23.141
      port: 6379
      password: root@1234
      database: 0

  cache:
    redis:
      time-to-live: 1800000

Linux系统中redis配置：

requirepass 1234
#bind 127.0.0.1 -::1
protected-mode no

Linux防火墙：

项目报错：

网上找了好多帖子，都没有解决，卡了老半天了，好难受。

密码不对，requirepass 1234表示redis密码是1234，springboot配置文件不是这个。
