springboot中更改RedisTemplate序列化方式

RedisTemplate默认的序列化方式为jdkSerializeable，会把对象序列化存储到Redis中（二进制形式），StringRedisTemplate的默认序列化方式为StringRedisSerializer。

通过配置，将RedisTemplate的序列化方式进行更改

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.GenericJackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

/**
 * @ClassName:RedisConfig
 * @Author:微微亮
 * @Description:
 * @Date:2020/11/11 20:48
 * @Version: 1.0
 */
@Configuration
public class RedisConfig {

    @Bean//参数--一个工厂
    public RedisTemplate redisTemplate(RedisConnectionFactory redisConnectionFactory){
        RedisTemplate redisTemplate = new RedisTemplate();
        //给redis模板先设置连接工厂，在设置序列化规则
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        //设置序列化规则
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(genericJackson2JsonRedisSerializer());
        redisTemplate.setHashKeySerializer(genericJackson2JsonRedisSerializer());
        redisTemplate.setHashValueSerializer(genericJackson2JsonRedisSerializer());
        return redisTemplate;
    }

    @Bean
    public GenericJackson2JsonRedisSerializer genericJackson2JsonRedisSerializer(){
        return new GenericJackson2JsonRedisSerializer();
    }
}

 这样在其他代码中

@Autowired
private RedisTemplate redisTemplate;

就可以自动装配（注入）使用了。
