废话不多说。直接开始

1，pom

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

2，配置文件

spring:
  redis:
    database: 0
    #    host: 192.168.1.48
    #    port: 6379
    #    password: 123456
    jedis:
      pool:
        max-active: 8
        max-wait: -1
        max-idle: 8
        min-idle: 0
    timeout: 10000
    cluster:
      nodes:
        - 192.168.1.48:9001
        - 192.168.1.48:9002
        - 192.168.1.48:9003
        - 192.168.1.48:9004
        - 192.168.1.48:9005
        - 192.168.1.48:9006

java代码

    }

    public String getString(String key) {
        return stringRedisTemplate.opsForValue().get(key);
    }
