需要的maven依賴 jar包，是對Jedis的封裝

maven依賴：

 專案的目錄結構：

redis中程式碼的封裝：

package com.toov5.service;

import java.util.Set;
import java.util.concurrent.TimeUnit;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.stereotype.Component;

@Component
 
public class RedisService {

    @Autowired
    private StringRedisTemplate stringRedisTemplate;
    //這樣該方法支援多種資料型別 
    public void set(String key , Object object, Long time){
        if (object instanceof String ) {  //判斷下是String型別不
            String argString =(String)object;  //強轉下
            //存放String型別的
            stringRedisTemplate.opsForValue().set(key, argString);
        }
        //如果存放Set型別
        if (object instanceof Set) {
            Set<String> valueSet =(Set<String>)object;
            for(String string:valueSet){
                stringRedisTemplate.opsForSet().add(key, string);  //此處點選下原始碼看下 第二個引數可以放好多
            }
        }
        //設定有效期
        if (time != null) {
            stringRedisTemplate.expire(key, time, TimeUnit.SECONDS);
        }
        
    }
    //做個封裝
    public void setString(String key, Object object){
        String argString =(String)object;  //強轉下
        //存放String型別的
        stringRedisTemplate.opsForValue().set(key, argString);
    }
    public void setSet(String key, Object object){
        Set<String> valueSet =(Set<String>)object;
        for(String string:valueSet){
            stringRedisTemplate.opsForSet().add(key, string);  //此處點選下原始碼看下 第二個引數可以放好多
        }
    }
    
    public String getString(String key){
     return    stringRedisTemplate.opsForValue().get(key);
    }
    
    
}

controller

package com.toov5.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import com.toov5.service.RedisService;

@RestController
public class IndexController {
  @Autowired
  private RedisService redisService;
    
   @RequestMapping("/setString")
   public String setString(String key, String value){
       redisService.set(key, value, 500l); //超時時間500s   l表示long型
       return "成功";
   }
   
   @RequestMapping("get")
   public String get(String key){
       return redisService.getString(key);
   }
}

啟動類

package com.toov5.app;

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

@SpringBootApplication(scanBasePackages={"com.toov5.*"})
public class app {
 public static void main(String[] args) {
    SpringApplication.run(app.class, args);
}
}

執行結果：

redis：

到期了後 就沒了哦 過期了
