com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Неизвестный столбец 'day0_.calendar_id' в 'списке полей'

Question

Я уже нашел несколько вопросов, которые были очень похожи на мои, но, к сожалению, ни одно из решений не помогло мне.

Мне нужно много к одному отношение между таблицей Календарь и днем. Календарь может иметь несколько дней.

вот мой код, спасибо за глядя на него:

Календарь класса:

@Entity 
@Table(name="calendars") 
@NamedQuery(name="Calendar.findAll", query="SELECT c FROM Calendar c") 

public class Calendar implements Serializable { 
private static final long serialVersionUID = 1L; 

@Id 
@Column(name="calendar_id") 
@GeneratedValue(strategy=GenerationType.IDENTITY) 
private int calendarId; 

private String background; 

@Temporal(TemporalType.DATE) 
private Date begindate; 

CalendarBean:

@EJB 
CalendarEJB calendarEJB; 

private static final long serialVersionUID = 1L; 

private String calendarName; 
private int calendarID; 

public String getCalendarName() { 
    return calendarName; 
} 

public void setCalendarName(String calendarName) { 
    this.calendarName = calendarName; 
} 

public int getCalendarID() { 
    return calendarID; 
} 

public void setCalendarID(int calendarID) { 
    this.calendarID = calendarID; 
} 

День класса:

@Entity 
@Table(name="days") 
@NamedQuery(name="Day.findAll", query="SELECT d FROM Day d") 
public class Day implements Serializable { 
private static final long serialVersionUID = 1L; 

@Id 
private int iddays; 

private int calendars_calendar_id; 

//bi-directional many-to-one association to Calendar 
@ManyToOne 
@JoinColumn(name="calendar_id") 
private Calendar calendar; 

public int getCalendars_calendar_id() { 
    return calendars_calendar_id; 
} 

public void setCalendars_calendar_id(int calendars_calendar_id) { 
    this.calendars_calendar_id = calendars_calendar_id; 
} 

DayBean:

@EJB 
DayEJB dayEJB; 

private static final long serialVersionUID = 1L; 

private int iddays; 
private int calendars_calendar_id; 

private CalendarBean calendarb = new CalendarBean(); 

public int getIddays() { 
    return iddays; 
} 

public void setIddays(int iddays) { 
    this.iddays = iddays; 
} 

public int getCalendars_calendar_id() { 
    return calendars_calendar_id; 
} 

public void setCalendars_calendar_id(int calendars_calendar_id) { 
    this.calendars_calendar_id = calendars_calendar_id; 
} 

public List<Day> allDays(){ 
    return dayEJB.listAllDays(); 

} 

MySQL:

CREATE TABLE IF NOT EXISTS `mydb`.`calendars` (
`calendar_id` INT(5) NOT NULL AUTO_INCREMENT, 
`calendarname` VARCHAR(45) NULL DEFAULT NULL, 
`background` BLOB NULL DEFAULT NULL, 
`begindate` DATE NULL DEFAULT NULL, 
`public` TINYINT(1) NULL DEFAULT NULL, 
PRIMARY KEY (`calendar_id`), 
UNIQUE INDEX `calender_id_UNIQUE` (`calendar_id` ASC)) 
ENGINE = InnoDB 
AUTO_INCREMENT = 121 
DEFAULT CHARACTER SET = utf8; 


-- ----------------------------------------------------- 
-- Table `mydb`.`days` 
-- ----------------------------------------------------- 
CREATE TABLE IF NOT EXISTS `mydb`.`days` (
`iddays` INT(10) NOT NULL AUTO_INCREMENT, 
`date` VARCHAR(45) NULL DEFAULT NULL, 
`text` VARCHAR(450) NULL DEFAULT NULL, 
`link` VARCHAR(45) NULL DEFAULT NULL, 
`calendars_calendar_id` INT(5) NOT NULL, 
PRIMARY KEY (`iddays`), 
INDEX `calendar_id_idx` (`calendars_calendar_id` ASC), 
CONSTRAINT `calendar_id` 
FOREIGN KEY (`calendars_calendar_id`) 
REFERENCES `mydb`.`calendars` (`calendar_id`) 
ON DELETE NO ACTION 
ON UPDATE NO ACTION) 
ENGINE = InnoDB 
AUTO_INCREMENT = 8 
DEFAULT CHARACTER SET = utf8; 

я изменил @JoinColumn (имя = «CALENDAR_ID») с именем ключа внешнего, но ошибка осталась, поэтому я переименовал внешний ключ к этому значению также без изменений. Если я переименую @JoinColumn (name = "calendar_id") в calendars_calendar_id, wildfly вообще не сможет развертываться.

Answer 1

Ваша модель объект не соответствует схеме базы данных.

модель субъект определяет ассоциацию Day -> Calendar, как это:

@Entity 
@Table(name = "days") 
public class Day implements Serializable { 

    @ManyToOne 
    @JoinColumn(name="calendar_id") 
    private Calendar calendar; 
} 

, но в базе данных, то ключевой столбец внешней называется calendars_calendar_id, не calendar_id.
