的java不能persis實體，也許是因爲布爾場

的我想堅持這個實體，聲明的java不能persis實體，也許是因爲布爾場

@Entity 
@Table(schema="app") 
public class Remainder { 

@Id 
@GeneratedValue(strategy=GenerationType.IDENTITY) 
private int id; 
private int amount; 
private String description; 
private boolean repeat; 
@ManyToOne 
@JoinColumn(name="CATEGORY") 
private Category category; 

@Column(name="DUE_DATE") 
private LocalDate dueDate;

我使用的EntityManager的persist（）方法。我得到這個異常：

[EL Warning]: 2015-08-30 11:14:56.341--UnitOfWork(1824877389)--Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.6.0.v20150309-bf26070): org.eclipse.persistence.exceptions.DatabaseException

Error Code: 1064 
Call: INSERT INTO app.REMAINDER (AMOUNT, DESCRIPTION, DUE_DATE, REPEAT, CATEGORY) VALUES (?, ?, ?, ?, ?) 
bind => [5 parameters bound]

這是表聲明

CREATE TABLE `remainder` (
    `id` int(11) NOT NULL AUTO_INCREMENT, 
    `amount` int(11) NOT NULL, 
    `description` varchar(100) NOT NULL, 
    `repeat` bit(1) DEFAULT NULL, 
    `category` varchar(100) NOT NULL, 
    `DUE_DATE` varchar(45) NOT NULL, 
    PRIMARY KEY (`id`), 
    KEY `FK_REMAINDER-Category_CATEGORY_SUB-ID_idx` (`category`), 
    CONSTRAINT `FK_REMAINDER-Category_CATEGORY_SUB-ID` FOREIGN KEY (`category`) REFERENCES `category` (`SUB_CATEGORY`) ON DELETE NO ACTION ON UPDATE NO ACTION 
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

我認爲這個問題是與布爾字段，請幫助

您是否嘗試過直接在數據庫中執行此查詢？你有一個DML查詢，因爲它是由jpa執行的，你有所有的值，現在如果你試圖自己做，只是連接到你的數據庫，那麼你可以改變或排除一些值來找到那些值，這會導致異常。 – Stanislav

@karimmohsen REPEAT是錯誤的，類別是一個實體（電力是ID），所以它是全部設置。 – usertest

@斯坦尼斯拉夫感謝男人花時間，我修復它 – usertest

我通過重命名列REPEAT反覆修復，因爲REPEAT是一個保留在mysql中工作的。
