如何在Springboot中使用RedisUtils工具类？针对这个问题，这篇文章详细介绍了相对应的分析和解答，希望可以帮助更多想解决这个问题的小伙伴找到更简单易行的方法。
SpringBoot整合Redis
引入Redis依赖
<!-- redis--><dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-redis</artifactId></dependency>设置Redis的Template
RedisConfig.java
package cn.wideth.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;@Configurationpublic class RedisConfig { @Bean public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) { RedisTemplate<String, Object> template = new RedisTemplate<>(); template.setConnectionFactory(factory); // 设置key的序列化方式 template.setKeySerializer(RedisSerializer.string()); // 设置value的序列化方式 template.setValueSerializer(RedisSerializer.json()); // 设置hash的key的序列化方式 template.setHashKeySerializer(RedisSerializer.string()); // 设置hash的value的序列化方式 template.setHashValueSerializer(RedisSerializer.json()); template.afterPropertiesSet(); return template; }}设置Redis连接信息
redis操作5种常见的数据类型
Redis工具类
redisTemplate API
opsForValue -> String
opsForSet -> Set
opsForHash -> hash
opsForZset -> SortSet
opsForList -> list队列

springboot一种全新的编程规范，其设计目的是用来简化新Spring应用的初始搭建以及开发过程，SpringBoot也是一个服务于框架的框架，服务范围是简化配置文件。
