Java Jackson XML到JSON未正确格式化列表

我正在将原始XML输入转换为JSON，但输出的所需结构存在问题（列表显示不正确）。导入的XML结构可能与下面的示例不同，因此使用POJO和简单的注释是不可行的。下面是XML输入示例：

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<gang>
    <id>435dfb3f-1129-4375-b0f9-09955d7434cc</id>
    <name>Brew's Crews</name>
    <members>
        <member>
            <member>d3433b1c-a93d-4af1-b698-89fcd921e48d</member>
            <dateJoined/>
        </member>
        <member>
            <member>8ac9f5bc-5710-4cb1-a75d-839e211f0286</member>
            <dateJoined/>
        </member>
    </members>
    <anthem/>
    <logo>http://localhost:8080/cloud/master-index-record/raw/58338b91-2390-44a7-ac31-581c5dd921e1</logo>
</gang>

生成了以下JSON：

{
  "id": "435dfb3f-1129-4375-b0f9-09955d7434cc",
  "name": "Brew's Crews",
  "members": {
    "member": {
      "member": "8ac9f5bc-5710-4cb1-a75d-839e211f0286",
      "dateJoined": null
    }
  },
  "anthem": null,
  "logo": "http://localhost:8080/cloud/master-index-record/raw/58338b91-2390-44a7-ac31-581c5dd921e1"
}

我的问题是“members”元素应分组在JSON数组中，如下所示：

"members":[{"member":blah,"dateJoined":null},{"member":blah2,"dateJoined":null}]

但它们不是……是否需要对XML映射器或对象映射器进行特定配置以实现这些期望的结果？

Jackson通常无法处理诸如

对象

之类的通用类型。当你这样做的时候-

Object entry = xmlMapper.readValue(result, Object.class);   

Jackson不知道应该反序列化的对象的结构

你可以试试这个-

class Member {
    private String memberId;
    private String dateJoined;
}

class Gang {
    private String id;
    private String name;
    private List<Member> members;
    private String anthem;
    private String logo;
}

class Test {

    public static void main(String[] args) {
        String result = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"no\"?><Gang><id>435dfb3f-1129-4375-b0f9-09955d7434cc</id><name>Brew's Crews</name><members><member><memberId>d3433b1c-a93d-4af1-b698-89fcd921e48d</memberId><dateJoined/></member><member><memberId>8ac9f5bc-5710-4cb1-a75d-839e211f0286</memberId><dateJoined/></member></members><anthem/><logo>http://localhost:8080/cloud/master-index-record/raw/58338b91-2390-44a7-ac31-581c5dd921e1</logo></Gang>";

        XmlMapper xmlMapper = new XmlMapper();
        xmlMapper.setVisibility(PropertyAccessor.FIELD, Visibility.ANY);

        Object entry = xmlMapper.readValue(result, Gang.class);   
        ObjectMapper jsonMapper = new ObjectMapper();
        jsonMapper.setVisibility(PropertyAccessor.FIELD, Visibility.ANY);

        System.out.println(jsonMapper.writeValueAsString(entry));
    }

}
