1、构建项目，选择Lombok（后面发现其实没有用到）、Web、Redis三个基本的Maven依赖。

2、准备Redis，这里可以参考历史文章的安装Redis环节，我使用Redis Desktop Manager桌面工具进行链接

《SpringBoot+Redis的入门教程》

3、构建项目目录，我构建了一个普通的web项目目录，切了dao层，仅仅由service、controller

《SpringBoot+Redis的入门教程》

4、填写application.yml，默认生成不是yml，不过我觉得yml视觉效果好一些，就改了一下，我们需要填写Redis链接信息

spring:
  redis:
    host: 192.168.192.133

5、构建service接口，这里普通实现两个set、get信息的业务

package com.github.myself.service;

/**
 * Created by MySelf on 2019/4/11.
 */
public interface MsgService {

    public String setMsg(String key,String msg);

    public String getMsg(String key);

}

6、接口实现，引入RedisTemplate

package com.github.myself.service.impl;

import com.github.myself.service.MsgService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Service;

/**
 * Created by MySelf on 2019/4/11.
 */
@Service
public class MsgServiceImpl implements MsgService {

    @Autowired
    private RedisTemplate redisTemplate;

    @Override
    public String setMsg(String key,String msg) {
        redisTemplate.opsForValue().set(key,msg);
        return "success";
    }

    @Override
    public String getMsg(String key) {
        return (String) redisTemplate.opsForValue().get(key);
    }
}

7、controller层的业务实现了

package com.github.myself.controller;

import com.github.myself.service.MsgService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

/**
 * Created by MySelf on 2019/4/11.
 */
@RestController
@RequestMapping("/msg")
public class MsgController {

    @Autowired
    private MsgService msgService;

    @GetMapping("/set")
    public String setMsg(@RequestParam(value = "key") String key,@RequestParam(value = "msg") String msg){
        return msgService.setMsg(key,msg);
    }

    @GetMapping("/get")
    public String getMsg(@RequestParam(value = "key") String key){
        return msgService.getMsg(key);
    }

}
