春季如何使用杰克逊代替JdkSerializationRedisSerializer [英] How to use jackson instead of JdkSerializationRedisSerializer in spring

问题描述

我在我的一个Java应用程序中使用Redis，并且正在序列化要存储在Redis中的对象列表.但是，我注意到使用RedisTemplate将使用JdkSerializationRedisSerializer.相反，我想使用Jackson进行序列化，因为我认为这样做对速度更好.我该如何配置RedisTemplate改为使用Jackson?

I'm using redis in one of my java apps and I'm serializing a list of objects to be stored in Redis. However, I noticed that using the RedisTemplate would use the JdkSerializationRedisSerializer. Instead, I'd like to use Jackson to serialize since I believe it is better for speed. How would I go about configuring my RedisTemplate to use Jackson instead?

为澄清起见，这是我配置RedisTemplate的方式:

For clarification, this is how I'm configuring my RedisTemplate:

@Override
protected RedisConfiguration getRedisConfiguration() {
    return redisConfiguration;
}

@Bean
public RedisTemplate<String, Object> getRedisTemplate() {
    RedisTemplate<String, Object> template = new RedisTemplate<>();
    template.setConnectionFactory(jedisConnectionFactory());
    return template;
}

推荐答案

像这样，

@Bean
public RedisTemplate<String, Object> getRedisTemplate() {
    RedisTemplate<String, Object> template = new RedisTemplate<>();
    Jackson2JsonRedisSerializer jrs = new Jackson2JsonRedisSerializer(String.class);
    template.setKeySerializer(jrs);
    template.setConnectionFactory(jedisConnectionFactory());
    return template;
}

，我建议您阅读此文档 https://docs.spring.io/spring-data/data-redis/docs/current/reference/html/#redis:template

and, I suggest you read this document https://docs.spring.io/spring-data/data-redis/docs/current/reference/html/#redis:template
