Java 使用QueryDSL和分页的Spring引导：嵌套数组元素上的页面排序不起作用

我使用Spring Boot QueryDSL过滤实体和Spring Boot Page功能进行分页和排序，以便调用以下方法：

Page<Country> all=countryRepository.findAll(predicate,pageable);

我得到以下结果：

            "id": "DE",
            "currency": "EUR",  
            "preSelection": 49,
            "currencySign": "€",
            "translations": [
                {

                },
                {

        },

                },
                {
                    "id": "23",

            ]
        },
        {

                    "name": "Portugal",
                    "text": null,
                    "languageId": "en"
                },
                {
                    "id": "17",
                    "name": "Portugal",
                    "text": null,
                    "languageId": "de"
                }
            ]
        }
]

好的，那就行了！ 但现在我想根据收集的翻译对象，根据它们的德语名称，对我的国家对象进行排序：

http://localhost:8090/countries?translations.languages.id=de&sort=translations.name

结果是：

好吧，那没用！有没有可能让它起作用
