springboot整合redis

Posted 2021-02-09 gongtaodj

向Redis中存储键值对时会出现，key：xACxEDx00x05tx00x1xxxxxxx　　value：xACxEDx00x05tx00 xxxxxx 的情况：

原因：springboot默认使用JdkSerializationRedisSerializer序列化方式

解决：需要改成StringRedisSerializer或直接使用Jedis的方式

 

@Configuration
@EnableCaching
public class RedisConfig extends CachingConfigurerSupport {
/**
     * redis模板，存储关键字是字符串，值是Jdk序列化
     * @param factory
     * @return
     * @Description:
     */
    @Bean
    public RedisTemplate<?, ?> redisTemplate(RedisConnectionFactory factory) {
        RedisTemplate<?, ?> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(factory);
        //key序列化方式;但是如果方法上有Long等非String类型的话，会报类型转换错误；
        RedisSerializer<String> redisSerializer = new StringRedisSerializer();//Long类型不可以会出现异常信息;
        redisTemplate.setKeySerializer(redisSerializer);
        redisTemplate.setHashKeySerializer(redisSerializer);

        //默认使用JdkSerializationRedisSerializer序列化方式;会出现乱码，改成StringRedisSerializer
        StringRedisSerializer stringSerializer = new StringRedisSerializer();
        redisTemplate.setKeySerializer(stringSerializer);
        redisTemplate.setValueSerializer(stringSerializer);
        redisTemplate.setHashKeySerializer(stringSerializer);
        redisTemplate.setHashValueSerializer(stringSerializer);
        return redisTemplate;
    }
}
