我有两个类PaymentJDO和PaymentItemJDO。付款可以有几个项目。任何付款项目都与发票相关联。 我想检索与特定发票相关的每笔付款。我有发票ID来查询。使用Google App Engine中的JDO查询集合属性
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class PaymentJDO implements BaseOwnedObject, BasicBean {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
protected Long id;
@Persistent
private Date date;
@Persistent
private String customerId;
@Persistent
private String pelicamoId = null;
@Persistent
@Element(dependent = "true")
private List<PaymentItemJDO> items;
public void setId(Long id) { this.id = id;}
public String getId() {
if(id == null) return null;
return id.toString();
}
public void setId(String id) {
if(id!=null) {
this.id = Long.parseLong(id);
}
}
public Date getDate() { return date;}
public void setDate(Date date) { this.date = date;}
public String getCustomerId() { return customerId;}
public void setCustomerId(String customerId) { this.customerId = customerId;}
public List<PaymentItemJDO> getItems() { return items;}
public void setItems(List<PaymentItemJDO> items) {this.items = items;}
public String getPelicamoId() { return pelicamoId;}
public void setPelicamoId(String pelicamoId) { this.pelicamoId = pelicamoId;}
}
@PersistenceCapable(identityType = IdentityType.APPLICATION, detachable="true")
public class PaymentItemJDO {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
protected Key id;
@Persistent
private String invoiceId;
@Persistent
private double amount;
public PaymentItemJDO(String invoiceId) {
setInvoiceId(invoiceId);
}
//override equals method for List .contains
@Override
public boolean equals(Object item) {
return ((PaymentItemJDO)item).getInvoiceId().equals(this.invoiceId);
}
public Key getId() { return id;}
public String getInvoiceId() { return invoiceId;}
public void setInvoiceId(String invoiceId) { this.invoiceId = invoiceId;}
public double getAmount() { return amount;}
public void setAmount(double amount) { this.amount = amount;}
}
我有一个功能来查询相关的特定发票
public List<PaymentJDO> getJDOPayments(String invoiceId) throws SessionExpiredException {
PersistenceManager pm = JdoUtil.getPm();
Query query = pm.newQuery(PaymentJDO.class);
String pelicamoId = getCurrentPelicamoId();
query.setFilter("items.contains(:invoice)");
return (List<PaymentJDO>) query.execute(new PaymentItemJDO(invoiceId));
}
我得到下一个错误
