JAXB无法正确地将Java Object属性编组为JSON（将其作为字符串编组）

Question

我正在使用JAXB来将Java对象编组为JSON，但是我遇到了这个框架的一些问题。

事实上，我的Java对象的大多数属性都是正确的marhsall，除了一个作为字符串的马歇尔。

这是我得到的部分输出：

"locations": [
                            {
                                "locationName": "Barcelone",
                                "locationCode": "HOTEL_FRED",
                                "codeType": "SPECIFIC",
                                "locationType": "HOTEL"
                            }

你们有没有人知道为什么只有“roomCombinations”没有正确编组？
