java Spring会话Redis如何配置RedistemAlte以使用jackson序列化器/反序列化器

Question

我想使用jackson serializer/de-serializer for在Spring redis中存储会话信息，但在如下配置redis tempalte之后，仍然使用JDKDefaultSerializer。 下面是stacktrace，我们可以看到它仍然使用JDKDefault序列化程序。如何重写以使用jackson序列化程序而不是默认的JDKSerializer

我想使用jackson序列化程序，因为我可以将objectmapper配置为在反序列化会话数据时忽略未知的proeprities和bean。在我们的例子中，一个微服务设置详细说明了会话中的对象，但在从另一个微服务检索会话时发现了“未找到类”异常，因为该类在第二个微服务源代码中不可用。非常感谢您为解决此问题提供的任何帮助

@Bean
public <K> RedisTemplate<String,K> redisTemplate(RedisConnectionFactory connectionFactory) {
    RedisTemplate<String, K> template = new RedisTemplate<>();
    template.setConnectionFactory(connectionFactory
        );
    Jackson2JsonRedisSerializer serializer = new Jackson2JsonRedisSerializer(Object.class);
    ObjectMapper mapper = new ObjectMapper();
    mapper.disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES);
    mapper.enable(DeserializationFeature.ACCEPT_EMPTY_STRING_AS_NULL_OBJECT);
    mapper.configure(SerializationFeature.FAIL_ON_EMPTY_BEANS, false);
    mapper.configure(SerializationFeature.WRITE_ENUMS_USING_TO_STRING, false);
    mapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);
    serializer.setObjectMapper(mapper);
    template.setDefaultSerializer(serializer);
    template.setKeySerializer(new StringRedisSerializer());
    template.setHashKeySerializer(serializer);
    template.setValueSerializer(serializer);
    template.afterPropertiesSet();
    return template;
}
