设置Redis的Template

package com.cyb.mobile.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.RedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

/**
 * @ClassName：RedisConfig
 * @Description：Redis配置类
 * @Author：chenyb
 * @Date：2020/8/16 11:48 下午
 * @Versiion：1.0
 */
@Configuration //当前类为配置类
public class RedisConfig {
    @Bean //redisTemplate注入到Spring容器
    public RedisTemplate<String,String> redisTemplate(RedisConnectionFactory factory){
        RedisTemplate<String,String> redisTemplate=new RedisTemplate<>();
        RedisSerializer<String> redisSerializer = new StringRedisSerializer();
        redisTemplate.setConnectionFactory(factory);
        //key序列化
        redisTemplate.setKeySerializer(redisSerializer);
        //value序列化
        redisTemplate.setValueSerializer(redisSerializer);
        //value hashmap序列化
        redisTemplate.setHashKeySerializer(redisSerializer);
        //key hashmap序列化
        redisTemplate.setHashValueSerializer(redisSerializer);
        return redisTemplate;
    }
}

设置Redis连接信息

# 连接的那个数据库
spring.redis.database=0
# redis服务的ip地址
spring.redis.host=192.168.199.142
# redis端口号
spring.redis.port=6379
# redis的密码，没设置过密码，可为空
spring.redis.password=12345678

Redis工具类

redisTemplate API

opsForValue ==》String
opsForSet ==》Set
opsForHash ==》hash
opsForZset ==》SortSet
opsForList ==》list队列
