我正在使用 EJB 和 JPA 开发 JavaEE 应用程序。
这是我的来源:
航类实体:
package com.airline.models;
import java.io.Serializable;
import java.util.Date;
import javax.persistence.*;
/**
* Entity implementation class for Entity: Flight
*
*/
@Entity
public class Flight implements Serializable {
private static final long serialVersionUID = 1L;
public Flight() {
super();
}
@Id()
@GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;
@Enumerated(EnumType.STRING)
private FlightDestination flightdestination;
@Enumerated(EnumType.STRING)
private FlightDestination flightorigin;
private Integer price;
@Temporal(TemporalType.TIMESTAMP)
private Date flighttime;
@OneToOne
@JoinColumn(name = "airplane_id")
private Airplane airplaneDetail;
public Airplane getAirplaneDetail() {
return airplaneDetail;
}
@Override
public String toString() {
return "Flight [id=" + id + ", flightdestination=" + flightdestination + ", flightorigin=" + flightorigin
+ ", price=" + price + ", flighttime=" + flighttime + "]";
}
// getters&setters
}
飞机实体:
public class Airplane implements Serializable {
private static final long serialVersionUID = 1L;
public Airplane() {
super();
}
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "id")
private Integer id;
private String planeMake;
private String modelName;
private Integer seatCapacity;
@OneToOne(mappedBy = "airplaneDetail")
private Flight flightDetail;
//getters&setters
}
尝试添加航类时发生错误。这是完整的堆栈跟踪:

有人可以帮我找出问题所在吗？
最佳答案
通过查看错误堆栈跟踪，如果您仔细观察引起的异常:
Caused by: java.sql.SQLSyntaxErrorException: 'AIRPLANE_ID' is not a column in table or VTI 'ADMIN.FLIGHT'.
在您的航类实体中，您似乎正在尝试通过 AIRPLANE_ID 加入:
@JoinColumn(name = "airplane_id")
但是 Airplane 实体中没有具有该名称的字段。
这就是您收到此异常的原因。
如果您尝试加入Airplane实体类中的id字段，您应该在Flight实体中指定:
@JoinColumn(name = "id")
或者根本不指定 @Joincolumn 名称属性(JPA 将使用 Airplane 实体中的默认 @Id 字段)。
希望这能解决您的问题。
关于java - 异常 : java. sql.SQLSyntaxErrorException: 'AIRPLANE_ID' 不是表中的列，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/58047408/
