Java 使用JAXB创建具有动态标记名的XML

我必须使用JAXB创建一个XML。 但它应该有动态标记名。 从POJO的设计和应用注释来看，这是令人困惑的部分

POJO结构应该是什么，类上应该使用哪些注释

我想要的XML的结构如下所示

根标签是“公司”，一个公司有许多“部门”，每个部门有许多动态的“子部门”，每个子部门有一个“经理”、“电话”和“工资”

（我对我的上述设计的效率和有效性有疑问，请证明其正确性）

以下是用JAXB注释标记的3个类：

1） 公司级

@XmlRootElement(name = "tarang")
public class Company {

    private List<Department> listDepartments;

    public Company(List<Department> listDepartments) {
        this.listDepartments = listDepartments;
    }

    public Company() {

    }

    @XmlElementRef
    public List<Department> getListDepartments() {
        return listDepartments;
    }

    public void setListDepartments(ArrayList<Department> listDepartments) {
        this.listDepartments = listDepartments;
    }

}

电流输出为：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

        <branch>
            <salary>50000</salary>

部门名称和分支名称既不会作为单独的标记追加，也不会作为属性追加。请通知注释标记中的更正以获得所需的输出。

如果所有标记名都是预先知道的，那么您可以使用

@xmlementref

、

@xmlementdecl

和

JAXBElement

的组合来映射您的用例

但是，从长远来看，如果数据能够更直接地表示出来，您可能会更高兴

Hai Blasise，我在链接中看到了示例，并进行了尝试。我认为我没有以正确的方式使用注释。我没有将“部门名称”和“分支机构名称”的名称附加为属性。请检查下面的当前输出：我得到的当前输出是50000 Manasa hr招聘99999999@Blasise Doughan，我编辑了问题并添加了我使用的3个类，这将为您提供正在应用和使用的注释的图片。请再次查看编辑后的问题，并建议我更正，以获得所需的输出。
