Redis-09 SpringBoot集成Redis

Jedis 和 lettuce 基本已经过时

集成RedisTemplate 单机
1.建 Modul 2.改pom

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    </build>

</project>

3.写yml （properties）

server.port=7777

spring.application.name=RedisTemplate

# ========================logging=====================
logging.level.root=info
logging.level.com.dc.cloud.redis7=info
logging.pattern.console=%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger- %msg%n 

#logging.file.name=D:/mylogs2023/redis7_study.log
logging.pattern.file=%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger- %msg%n

# ========================swagger=====================
spring.swagger2.enabled=true
#?springboot2.6.X??swagger2.9.X???documentationPluginsBootstrapper??????
#????springboot2.6.X??SpringMVC?????????AntPathMatcher???PathPatternParser?
# ??????????matching-strategy?????ant_path_matcher
spring.mvc.pathmatch.matching-strategy=ant_path_matcher

# ========================redis??=====================
spring.redis.database=0
# ???????IP
spring.redis.host=192.168.248.132
spring.redis.port=6379
spring.redis.password=dc123
spring.redis.lettuce.pool.max-active=8
spring.redis.lettuce.pool.max-wait=-1ms
spring.redis.lettuce.pool.max-idle=8
spring.redis.lettuce.pool.min-idle=0

4.主启动

@SpringBootApplication
public class Redis7777
{
    public static void main(String[] args)
    {
        SpringApplication.run(Redis7777.class,args);
    }
}

5.业务类

解决方法1：改用 StringRedisTemplate

解决方法2：配置RedisConfig

package com.dc.cloud.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

/**
 * @Title: RedisConfig
 * @Author：代超
 * @Package：com.dc.cloud.config
 * @Date：2024/11/23 19:58
 * @description:
 */
@Configuration
public class RedisConfig
{
    /**
     * redis序列化的工具配置类，下面这个请一定开启配置
     * 127.0.0.1:6379> keys *
     * 1) "ord:102"  序列化过
     * 2) "\xac\xed\x00\x05t\x00\aord:102"   野生，没有序列化过
     * this.redisTemplate.opsForValue(); //提供了操作string类型的所有方法
     * this.redisTemplate.opsForList(); // 提供了操作list类型的所有方法
     * this.redisTemplate.opsForSet(); //提供了操作set的所有方法
     * this.redisTemplate.opsForHash(); //提供了操作hash表的所有方法
     * this.redisTemplate.opsForZSet(); //提供了操作zset的所有方法
     * @param lettuceConnectionFactory
     * @return
     */
    @Bean
    public RedisTemplate<String, Object> redisTemplate(LettuceConnectionFactory lettuceConnectionFactory)
    {
        RedisTemplate<String,Object> redisTemplate = new RedisTemplate<>();

        redisTemplate.setConnectionFactory(lettuceConnectionFactory);
        //设置key序列化方式string
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        //设置value的序列化方式json，使用GenericJackson2JsonRedisSerializer替换默认序列化
        redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer());

        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        redisTemplate.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());

        redisTemplate.afterPropertiesSet();

        return redisTemplate;
    }
}
