java - “无法在bigint上调用方法。”错误（使用JPA）

Question

我在java中的查询中一直使用JPQL。我遇到了这个问题。

Exception in thread "AWT-EventQueue-0" javax.persistence.PersistenceException: Exception [EclipseLink-4002]  (Eclipse Persistence Services - 2.5.1.v20130918-f2b9fc5): org.eclipse.persistence.exceptions.DatabaseException
Internal Exception: java.sql.SQLException: Cannot call methods on bigint.
Error Code: 258

这是我在jpql中的查询：

TypedQuery<WholeResultRecord> query = em.createQuery("SELECT NEW project.WholeResultRecord(v,c,h) FROM Vehiclehistory AS h JOIN h.vehicleID AS v ON h.vehicleID = v.vehicleID JOIN h.clientID AS c ON h.clientID = c.clientID",WholeResultRecord.class);
WholeResultRecord result = query.getSingleResult();
result.go();

WholeResultRecord.java

package project;

public class WholeResultRecord {

    private Vehicles vehicle;
    private Clients client;
    private Vehiclehistory history;

    public WholeResultRecord(Vehicles vehicle, Clients client, Vehiclehistory history){
        this.vehicle = vehicle;
        this.client = client;
        this.history = history;
    }

    protected void go(){
        System.out.println(vehicle.toString());
        System.out.println(client.toString());
        System.out.println(history.toString());
    }

}

我认为查询没问题。因为错误行在

中

  

WholeResultRecord result = query.getSingleResult（）;

我已经阅读了有关此错误的其他问题，但这些都与我的相关。他们说必须使用 T-SQL 吗？

请帮帮我。谢谢。

等...

我的表格是Vehiclehistory，Clients，Vehicles。
