次の XML ドキュメントを JAXB Java オブジェクトに非整列化しようとしています。
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<company>
<name>ABC Inc</name>
<address>123 1st Street, My City, AB</address>
<employees>
<employee>
<firstName>John</firstName>
<lastName>Doe</lastName>
</employee>
<employee>
<firstName>John2</firstName>
<lastName>Doe2</lastName>
</employee>
</employees>
</company>
次の Java コードを使用しましたが、XML に 2 つの要素が含まれていても、子コレクション (company.getEmployees()) には要素が含まれていませんでした。
JAXBContext jc = JAXBContext.newInstance("com.abc");
Unmarshaller unmarshaller = jc.createUnmarshaller();
JAXBElement<Company> root = unmarshaller.unmarshal(new StreamSource(new FileInputStream( "TestCompany.xml" )), Company.class);
Company company = root.getValue();
List<Employee> employees = company.getEmployees();
JAXB で生成されたクラスは次のとおりです。
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "company", propOrder = {
"name",
"address",
"employees"
})
public class Company {
@XmlElement(required = true)
protected String name;
@XmlElement(required = true, nillable = true)
protected String address;
protected List<Employee> employees;
public String getName() {
return name;
}
public void setName(String value) {
this.name = value;
}
public String getAddress() {
return address;
}
public void setAddress(String value) {
this.address = value;
}
public List<Employee> getEmployees() {
if (employees == null) {
employees = new ArrayList<Employee>();
}
return this.employees;
}
}
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "employee", propOrder = {
"firstName",
"lastName"
})
public class Employee {
@XmlElement(required = true)
protected String firstName;
@XmlElement(required = true)
protected String lastName;
public String getFirstName() {
return firstName;
}
public void setFirstName(String value) {
this.firstName = value;
}
public String getLastName() {
return lastName;
}
public void setLastName(String value) {
this.lastName = value;
}
}
