我必须使用 JAXB 创建一个 XML。但它应该有动态标签名称。这就是 POJO 的设计和在其上应用注释方面令人困惑的部分。
POJO 结构应该是什么，类上应该使用哪些注解。
我想要的 XML 的结构如下。
根标签是“公司”，一个公司有很多“部门”，每个部门都有很多动态的“子部门”，每个子部门都有“经理”、“电话”和“工资”。
<company>
<department>
<hr>
<hr-recruitment>
<manager> Manasa </manager>
<phone>992222222</phone>
<salary> 20000 </salary>
</hr-recruitment>
<hr-finance>
<manager> Sunder </manager>
<phone>993333332</phone>
<salary> 50000 </salary>
</hr-finance>
</hr>
</department>
<department>
<transport>
<transport-employee>
<manager> Raman </manager>
<phone>888888888</phone>
<salary> 30000 </salary>
</transport-employee>
<transport-goods>
<manager> Sheela </manager>
<phone>99999999</phone>
<salary> 75000 </salary>
</transport-goods>
</transport>
</department>
</company>
请建议我最好的 java 类设计、它们的元素和所需的注释以及结构，以便我可以在我的应用程序中以更好的方式使用 Jaxb。
我目前的设计包含 3 个类。
1) 公司 2) 部门 3) 分公司
关系是：
1) class Company -has a- List of Departments.
2) class Department -has a- name (String).
3) class Department -has a- List of Branches.
4) class Branch -has a- name (String)
5) class Branch -has a- manager (String)
6) class Branch -has a- phone (String)
7) class Branch -has a- salary (String)
（我对上述设计的效率和有效性有疑问，请证明其正确性）。
以下是标有 JAXB 注释的 3 个类：
1) 公司.class
@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;
}
}
2) 部门.class
@XmlRootElement(name = "department")
public class Department {
private String strDepartmentName;
private List<Branch> listBranchs;
public Department(String strDepartmentName, List<Branch> listBranchs) {
this.strDepartmentName = strDepartmentName;
this.listBranchs = listBranchs;
}
public Department() {
}
@XmlElement(name = "name")
public String getStrDepartmentName() {
return strDepartmentName;
}
public void setStrDepartmentName(String strDepartmentName) {
this.strDepartmentName = strDepartmentName;
}
@XmlElementRef
public List<Branch> getListBranchs() {
return listBranchs;
}
public void setListBranchs(List<Branch> listBranchs) {
this.listBranchs = listBranchs;
}
}
3) 分支.class
@XmlRootElement(name = "branch")
public class Branch {
private String strName;
private String strManagerName;
private String strPhone;
private int intSalary;
public Branch(String strName, String strManagerName, String strPhone,
int intSalary) {
this.strName = strName;
this.strManagerName = strManagerName;
this.strPhone = strPhone;
this.intSalary = intSalary;
}
public Branch() {
// TODO Auto-generated constructor stub
}
@XmlElement(name = "name")
public String getStrName() {
return strName;
}
public void setStrName(String strName) {
this.strName = strName;
}
@XmlElement(name = "manager")
public String getStrManagerName() {
return strManagerName;
}
public void setStrManagerName(String strManagerName) {
this.strManagerName = strManagerName;
}
@XmlElement(name = "phone")
public String getStrPhone() {
return strPhone;
}
public void setStrPhone(String strPhone) {
this.strPhone = strPhone;
}
@XmlElement(name = "salary")
public int getIntSalary() {
return intSalary;
}
public void setIntSalary(int intSalary) {
this.intSalary = intSalary;
}
}
当前输出为：
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<tarang>
<department>
<branch>
<salary>50000</salary>
<manager>Manasa</manager>
<name>hr-recruitment</name>
<phone>999999999</phone>
</branch>
<branch>
<salary>40000</salary>
<manager>Sundar</manager>
<name>hr-finance</name>
<phone>888888888</phone>
</branch>
<name>hr</name>
</department>
<department>
<branch>
<salary>30000</salary>
<manager>Raman</manager>
<name>transport-employee</name>
<phone>7777777777</phone>
</branch>
<branch>
<salary>20000</salary>
<manager>Sheela</manager>
<name>transport-goods</name>
<phone>6666666666</phone>
</branch>
<name>tranport</name>
</department>
</tarang>
部门名称和分支名称既不会作为单独的标记，也不会作为属性附加。请通知注释标记中的更正以获得我想要的输出。
