## 一、Maven依赖 ##

<parent>
        <groupId>org.springframework.boot</groupId>

            </dependency>
        </dependencies>
    </dependencyManagement>

## 二、工具类 ##

package com.demo.utils;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.data.redis.core.StringRedisTemplate;
    import org.springframework.stereotype.Component;
    
    import java.util.concurrent.TimeUnit;
    
    /**
     * @Author: JYC
     * @Title: RedisUtils
     * @Description: TODO
     * @Date: 2022/4/27 16:29
     */
    @Component
    public class RedisUtils {
        
    
        @Autowired
        private StringRedisTemplate stringRedisTemplate;
    
        public void setString(String key, String value) {
        
            setString(key, value, null);
        }
    
        public void setString(String key, String value, Long timeOut) {
        
            stringRedisTemplate.opsForValue().set(key, value);
            if (timeOut != null) {
        
                stringRedisTemplate.expire(key, timeOut, TimeUnit.SECONDS);
            }
        }
    
        public String getString(String key) {
        
            return stringRedisTemplate.opsForValue().get(key);
        }
    }

## 三、控制层 ##

package com.demo.controller;
    
    import com.alibaba.fastjson.JSONObject;
    import com.demo.entity.UserEntity;
    import com.demo.utils.RedisUtils;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    /**
     * @Author: JYC
     * @Title: RedisController
     * @Description: TODO
     * @Date: 2022/4/27 16:34
     */
    @RestController
    public class RedisController {
        
        @Autowired
        private RedisUtils redisUtils;
    
        @RequestMapping("/setRedis")
        public void setRedisKey(UserEntity userEntity) {
        
            redisUtils.setString("userEntity", JSONObject.toJSONString(userEntity));
        }
    
        @RequestMapping("/getRedis")
        public UserEntity setRedisKey() {
        
            String userEntityJson = redisUtils.getString("userEntity");
            UserEntity userEntity = JSONObject.parseObject(userEntityJson, UserEntity.class);
            return userEntity;
        }
    }

## 四、配置文件 ##

spring:
      redis:
        host: 192.168.1.100
        password: root
        port: 6379
