将SOAP POJO打印到字符串

我在下面提供了一个SOAP Pojo对象：

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "Deposit", propOrder = {
    "amount",
    "bag",
    "businessDate",
    "depositTypeId",
    "id",
    "notes",
    "number",
    "time"
})
public class Deposit {

    @XmlElement(name = "Amount")
    protected BigDecimal amount;
    @XmlElementRef(name = "Bag", namespace = "http://www.brinksoftware.com/webservices/sales/v2", type = JAXBElement.class, required = false)
    protected JAXBElement<String> bag;
    @XmlElement(name = "BusinessDate")
    @XmlSchemaType(name = "dateTime")
    protected XMLGregorianCalendar businessDate;
    @XmlElement(name = "DepositTypeId")
    protected Integer depositTypeId;
    @XmlElement(name = "Id")
    protected Integer id;
    @XmlElementRef(name = "Notes", namespace = "http://www.brinksoftware.com/webservices/sales/v2", type = JAXBElement.class, required = false)
    protected JAXBElement<String> notes;
    @XmlElement(name = "Number")
    protected Integer number;
    @XmlElement(name = "Time")
    protected DateTimeOffset time;

    public BigDecimal getAmount() {
        return amount;
    }

    public void setAmount(BigDecimal value) {
        this.amount = value;
    }

    public JAXBElement<String> getBag() {
        return bag;
    }

    public void setBag(JAXBElement<String> value) {
        this.bag = value;
    }

    public XMLGregorianCalendar getBusinessDate() {
        return businessDate;
    }

    public void setBusinessDate(XMLGregorianCalendar value) {
        this.businessDate = value;
    }

    public Integer getDepositTypeId() {
        return depositTypeId;
    }

    public void setDepositTypeId(Integer value) {
        this.depositTypeId = value;
    }

    public Integer getId() {
        return id;
    }

    public void setId(Integer value) {
        this.id = value;
    }

    public JAXBElement<String> getNotes() {
        return notes;
    }

    public void setNotes(JAXBElement<String> value) {
        this.notes = value;
    }

    public Integer getNumber() {
        return number;
    }

    public void setNumber(Integer value) {
        this.number = value;
    }

    public DateTimeOffset getTime() {
        return time;
    }

    public void setTime(DateTimeOffset value) {
        this.time = value;
    }
}

在调试时，我得到类似的值。

由于它没有任何toString方法，如何将POJO打印到String？
