一、添加jar

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

二、添加 redis配置

#redis
spring.redis.host=localhost
spring.redis.port=6379
#spring.redis.password=123456
spring.redis.database=0
spring.redis.pool.max-active=8 
spring.redis.pool.max-idle=8 
spring.redis.pool.max-wait=-1 
spring.redis.pool.min-idle=0 
spring.redis.timeout=0

三、添加工具类

package com.drunck.utils;

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

@Component
public class RedisUtil {
    @Autowired
    private StringRedisTemplate stringRedisTemplate;

    public void set(String key, String value) {
        this.stringRedisTemplate.opsForValue().set(key, value);
    }

    public String get(String key) {
        return this.stringRedisTemplate.opsForValue().get(key);
    }

    public void del(String key) {
        this.stringRedisTemplate.delete(key);
    }
}

四、使用

if(CommonUtil.isNotEmpty(redisUtil)) {
    System.out.println(redisUtil.get("key"));
} else {
    redisUtil.set("key", "redis");
}
