我想通過JAXB將帶有java.time.Localdate（JSR-310）的Object轉換為XML，但輸出錯誤

Question

我想轉換一個帶有java.time.Localdate（JSR-310）的Object和一個通過JAXB將Localdate包裝到XML但是輸出錯誤的屬性。

public <T> void printPdf(T obj) {
    // create xml
    JAXBContext context = JAXBContext.newInstance(obj.getClass());
    Marshaller m = context.createMarshaller();
    m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
    StringWriter outWriter = new StringWriter();
    StreamResult result = new StreamResult(outWriter);
    m.marshal(obj, result);

    StringBuffer sb = outWriter.getBuffer();
    String finalstring = sb.toString();
    System.out.println(finalstring);
}

這是對象：

@XmlRootElement
public class Invoice implements Validateable {
    private LocalDate date = LocalDate.now();
    private ObjectProperty<LocalDate> dueDate = new SimpleObjectProperty<LocalDate>(
            LocalDate.now().plusDays(20));
    // ========================================================================
    // date
    // ========================================================================
    public LocalDate getDate() {
        return date;
    }
    public void setDate(LocalDate date) {
        this.date = date;
    }
    // ========================================================================
    // companyName
    // ========================================================================
    public LocalDate getDueDate() {
        return this.dueDate.get();
    }
    public void setDueDate(LocalDate duedate) {
        this.dueDate.set(duedate);
    }
    public final ObjectProperty<LocalDate> dueDateProperty() {
        return dueDate;
    }
}

這是XML輸出：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<invoice>
    <date/>
    <dueDate/>
</invoice>

我怎樣才能正確轉換？ 如果有更好的東西，我不會停止使用JAXB。

您可以使用JAXB XmlAdapter來控制JSR-310對象如何轉換為XML或從XML轉換。
