備註：本系列開發工具均爲IDEA

一、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。

二、準備Redis，這裏能夠參考歷史文章的安裝Redis環節，我使用Redis Desktop Manager桌面工具進行連接

三、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

四、填寫application.yml，默認生成不是yml，不過我以爲yml視覺效果好一些，就改了一下，咱們須要填寫Redis連接信息

spring:
 redis:
 host: 192.168.192.133

五、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);

}
複製代碼

六、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);
    }
}
複製代碼

七、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);
    }

}
複製代碼

八、啓動項目，使用Postmane測試
