启动类

package com.hbk;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application {


    public static void main(String[] args) {
        SpringApplication.run(Application.class);
    }
}

控制器类

package com.hbk.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class TestController {

    @Autowired
    private RedisTemplate redisTemplate;

    @RequestMapping("/test")
    public String test(){
        redisTemplate.opsForValue().set("spring-r-cluster-1", "黄宝康");
        redisTemplate.opsForValue().set("spring-r-cluster-2", 456);
        System.out.println(redisTemplate.opsForValue().get("spring-r-cluster-1"));
        System.out.println(redisTemplate.opsForValue().get("spring-r-cluster-2"));
        return "ok";
    }
}
