Question

我在尝试将实体类持久化到Oracle数据库时遇到错误。这是我的实体类

    package com.airline.models;

import java.io.Serializable;
import java.time.LocalDate;

import javax.persistence.Entity;
import javax.persistence.EnumType;
import javax.persistence.Enumerated;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.SequenceGenerator;
import javax.persistence.Transient;

/**
 * Entity implementation class for Entity: Passenger
 *
 */
@Entity

public class Passenger implements Serializable {

    @Transient
    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(generator = "PASSENGER_SEQ")
    @SequenceGenerator(name="PASSENGER_SEQ",sequenceName="PASSENGER_SEQ1", allocationSize=1)
    private Integer id;

    private String firstName;
    private String lastName;

    private LocalDate dob;

    @Enumerated(EnumType.STRING)
    private Gender gender;

    @Enumerated(EnumType.STRING)
    private FlightClass flightClass;

    ...
}

以及为LocalDate类型实现AtributeConverter的类

   package com.airline.converter;

    import java.time.LocalDate;
    import java.sql.Date;

    import javax.persistence.AttributeConverter;
    import javax.persistence.Converter;

    @Converter(autoApply = true)
    public class LocalDateAttributeConverter implements AttributeConverter<LocalDate, Date> {

        @Override
        public Date convertToDatabaseColumn(LocalDate locDate) {
            return (locDate == null ? null : Date.valueOf(locDate));

        }

        @Override
        public LocalDate convertToEntityAttribute(Date sqlDate) {
            return (sqlDate == null ? null : sqlDate.toLocalDate());
        }
    }

然而，当我试图坚持它时，我收到了这个错误：

> 

    Caused by: Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.6.4.qualifier): org.eclipse.persistence.exceptions.DatabaseException
    Internal Exception: java.sql.SQLException: ORA-00942: table or view does not exist
    Error Code: 942
    Call: INSERT INTO PASSENGER (ID, DOB, FIRSTNAME, FLIGHTCLASS, GENDER, LASTNAME) VALUES (?, ?, ?, ?, ?, ?)
        bind => [6 parameters bound]
    Query: InsertObjectQuery(com.airline.models.Passenger@2441be63)

我正在使用Eclipse Link作为持久性单元。 Persistence.xml：

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
    <persistence-unit name="airline">
        <jta-data-source>jdbc/airline</jta-data-source>
        <class>com.airline.models.Passenger</class>
        <properties>
            <property name="eclipselink.ddl-generation" value="drop-and-create-tables" />
        </properties>
    </persistence-unit>
</persistence>

如何持久保存实体类。
