Hibernate/JPA查詢語言具有子查詢的新實體構造函數 - 無法找到合適的構造函數

我有訂單和訂單欺詐警報。該關聯只能從欺詐警報到訂單，而不是相反。Hibernate/JPA查詢語言具有子查詢的新實體構造函數 - 無法找到合適的構造函數

public class FraudAlerts 
... 
@ManyToOne 
@JoinColumn(name = "customerOrderId") 
private CustomerOrder customerOrder;

我的查詢是這樣的：

"select new com.acme.struts.search.FraudOrderSearchViewModel" 
+ "(co.orderId, co.orderPlacedDate, tot.totalIncVat, adr.email, co.customerNumber, co.ipAddress, " 
+ "(select name from FraudAlerts where co.orderId = customerOrder))" 
+ " from CustomerOrder as co join co.customerBillTo adr join co.originalTotal as tot");

你可以看到我使用子查詢來獲取被accociated這個順序作爲一個集合所有fraudAlert名稱和傳遞給視圖模型bean FraudOrderSearchViewModel。

我的問題是，Hibernate不會爲它找到合適的構造函數，並拋出一個異常：

java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: Unable to locate appropriate constructor on class [com.acme.struts.search.FraudOrderSearchViewModel] [select new com.acme.struts.search.FraudOrderSearchViewModel(co.orderId, co.orderPlacedDate, tot.totalIncVat, adr.email, co.customerNumber, co.ipAddress, (select name from com.acme.data.model.fraud.FraudAlerts where co.orderId = customerOrder)) from com.acme.data.model.customer.CustomerOrder as co join co.customerBillTo adr join co.originalTotal as tot]

at com.acme.services.fraud.FraudHibQueryTest.testFraudServiceHibQuery(FraudHibQueryTest.java:72)

我的構造函數如下：

public FraudOrderSearchViewModel(final String orderId, final Date datePlaced, final BigDecimal originalTotal, final String customerEmail, final String customerId, 
     final String ipAddress, final Object[] holdReason)

我試過的String []，列表列出無濟於事。 hibernate希望我使用什麼類型的構造函數變量？
