springboot中更改RedisTemplate序列化方式

RedisTemplate默認的序列化方式為jdkSerializeable，會把對象序列化存儲到Redis中（二進制形式），StringRedisTemplate的默認序列化方式為StringRedisSerializer。

通過配置，將RedisTemplate的序列化方式進行更改

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//參數--一個工廠
    public RedisTemplate redisTemplate(RedisConnectionFactory redisConnectionFactory){
        RedisTemplate redisTemplate = new RedisTemplate();
        //給redis模板先設置連接工廠，在設置序列化規則
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        //設置序列化規則
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(genericJackson2JsonRedisSerializer());
        redisTemplate.setHashKeySerializer(genericJackson2JsonRedisSerializer());
        redisTemplate.setHashValueSerializer(genericJackson2JsonRedisSerializer());
        return redisTemplate;
    }

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

 這樣在其他代碼中

@Autowired
private RedisTemplate redisTemplate;

就可以自動裝配（注入）使用了。
