SpringBoot学习之配置Redis

1.pom.xml中操作redis需要引入的包

2.appliction.properties中配置redis信息

3.创建redis的java配置类

4.实际代码中调用

 

2025年3月27日更新：关于SpringBoot3.0整合Redis序列化配置Jackson2JsonRedisSerializer的问题

SpringBoot3.0版本后，弃用了setObjectMapper(objectMapper)，而是改为了new Jackson2JsonRedisSerializer<>(objectMapper, Object.class)：代码如下

@Configuration
public class RedisConfig {

    @Bean("redisTemplate")
    @Scope("prototype")
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {

        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);

        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        objectMapper.activateDefaultTyping(LaissezFaireSubTypeValidator.instance, ObjectMapper.DefaultTyping.NON_FINAL);
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<>(objectMapper, Object.class);

        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);

        return redisTemplate;
    }
}
