Redis自定义序列化工具

Redis自定义序列化工具

在用Spring Boot 使用Redis命令时会出现乱码问题

解决乱码问题写序列化工具

@Configuration
public class RedisConfig {
    

 @Bean //主动注册了一个名字叫redisTemplate 的bean
    public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory)
    {
        RedisTemplate<Object, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(redisConnectionFactory);

        Jackson2JsonRedisSerializer jackson = new Jackson2JsonRedisSerializer(Object.class);

        ObjectMapper  mapper = new ObjectMapper();

        // 启用默认类型推理，将类型信息作为属性写入JSON
        // 就是把对象的全类名写入json
        mapper.activateDefaultTyping( mapper.getPolymorphicTypeValidator(), ObjectMapper.DefaultTyping.NON_FINAL);

        jackson.setObjectMapper(mapper);
        template.setKeySerializer(StringRedisSerializer.UTF_8);
        template.setValueSerializer(jackson);
        template.setHashKeySerializer(StringRedisSerializer.UTF_8);
        template.setHashValueSerializer(jackson);
        return template;
    }

}
