使用RedisTemplate前需要配置的类

@Configuration
public class RedisTemplateConfig {
    @Bean
    @Primary
    public RedisTemplate<String,Object> redisCacheTemplate(LettuceConnectionFactory redisConnectionFactory){
        RedisTemplate<String,Object> template = new RedisTemplate<>();
        template.setConnectionFactory(redisConnectionFactory);
        FastJsonRedisSerializer fastJsonRedisSerializer = new FastJsonRedisSerializer(Object.class);
        // key 的序列化方式为 string 序列化方式
        template.setKeySerializer(new StringRedisSerializer());
        template.setHashKeySerializer(new StringRedisSerializer());
        template.setValueSerializer(fastJsonRedisSerializer);
        template.setHashValueSerializer(fastJsonRedisSerializer);
        template.setDefaultSerializer(fastJsonRedisSerializer);
        template.afterPropertiesSet();
        return template;
    }
}
