Redis操作工具类

前期文章中关于RedisOperateUtil工具类使用时需要强制类型转换,针对List等操作不方便,为此特意更新RedisOperateUtil工具类,前文链接:https://blog.csdn.net/liwenyang1992/article/details/111771097?spm=1001.2014.3001.5501

通过Docker搭建Redis环境并启动,命令如下:

#docker启动redis服务
docker run -itd --name redis -p 6379:6379 redis
#使用redis-cli连接redis
docker exec -it redis redis-cli

application.properties配置如下:

server.port=8080
server.servlet.context-path=/redis

由于SpringBoot 2.0版本之后spring-boot-starter-data-redis的底层默认使用了Lettuce来操作redis,早期的版本使用的是Jedis,使用Lettuce获取连接都是通过LettuceConnectionFactory这个工厂类来获取的,默认情况下Lettuce使用的是一个线程安全的共享的本地连接来操作Redis,如果你不希望使用本地连接可以设置shareNativeConnection这个参数为false。备注:RedisTemplate底层使用commons-pool2来作为连接池。

备注:默认情况下RedisTemplate是不使用连接池的,并且性能还是不错的。

RedisConfiguration配置如下:

package com.lwy.it.configuration;

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.jsontype.impl.LaissezFaireSubTypeValidator;

import org.springframework.cache.interceptor.CacheErrorHandler;
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.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

/**
 * 使用Jackson2JsonRedisSerializer序列化和反序列化
 */
@Configuration
public class RedisConfiguration extends CachingConfigurerSupport {

    @Bean("redisTemplate")
    public RedisTemplate redisTemplate(LettuceConnectionFactory lettuceConnectionFactory) {
        RedisTemplate redisTemplate = new RedisTemplate();
        // 启用连接共享
        lettuceConnectionFactory.setShareNativeConnection(true);
        // 配置连接工厂
        redisTemplate.setConnectionFactory(lettuceConnectionFactory);
        // 使用Jackson2JsonRedisSerializer来序列化和反序列化Redis的value值
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
        ObjectMapper objectMapper = new ObjectMapper();
        // 指定药序列化的域,field,get和set,以及修饰符范围
        // ANY任何级别的字段都可以自动识别
        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        // 指定序列化输入的类型,类必须是非final修饰的,final修饰的类,比如String,Integer等会抛出异常
        objectMapper.activateDefaultTyping(LaissezFaireSubTypeValidator.instance, ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(objectMapper);
        // value采用Json序列化
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        // 使用StringRedisSerializer来序列化和反序列化Redis的key
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        // 使用StringRedisSerializer来序列化和反序列化Redis的Hash key
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        // Hash value采用Json序列化
        redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);
        return redisTemplate;
    }

    @Override
    public CacheErrorHandler errorHandler() {
        return new RedisCacheErrorHandler();
    }

}

核心Redis操作工具类RedisOperateUtil如下,主要包括Redis键(Key)、字符串(String)、哈希(Hash)、列表(List)、集合(Set)等常用的操作。
