java - 有没有办法将响应实体存储在redis缓存中？

Question

我尝试了以下代码但出现错误 - spring web ResponseEntity 无法序列化。

org.springframework.data.redis.serializer.SerializationException: Cannot serialize; nested exception is org.springframework.core.serializer.support.SerializationFailedException: Failed to serialize object using DefaultSerializer; nested exception is java.lang.IllegalArgumentException: DefaultSerializer requires a Serializable payload but received an object of type [org.springframework.http.ResponseEntity]

尝试了以下代码:

@Override

@Transactional

@Cacheable(value = "mostFollowedSub", key = "{#root.methodName, #offset, #limit}" )
    public ResponseEntity<Response> mostFollowedSubCategory(int offset, int limit) {
        return subCategoryDao.getMostFollowedSubCategory(offset, limit);
    }

Answer 1

ResponseEntity 不是Serializable。更好的方法是在服务/DAO 层进行缓存(在您的情况下是 subCategoryDao 的 getMostFollowedSubCategory 方法)。
