備註：本系列開發工具均爲IDEA

1、構建項目，選擇Lombok（後面發現其實沒有用到）、Web、Redis三個基本的Maven依賴。

            </plugin>
        </plugins>
    </build>

</project>

2、準備Redis，這裏可以參考歷史文章的安裝Redis環節，我使用Redis Desktop Manager桌面工具進行鏈接

3、構建項目目錄，我構建了一個普通的web項目目錄，切了dao層，僅僅由service、controller

4、填寫application.yml，默認生成不是yml，不過我覺得yml視覺效果好一些，就改了一下，我們需要填寫Redis鏈接信息

spring:
  redis:
    host: 192.168.192.133

5、構建service接口，這裏普通實現兩個set、get信息的業務

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、接口實現，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層的業務實現了

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);
    }

}

8、啓動項目，使用Postmane測試
