休眠h2可嵌入列表预期的“标识符". [英] hibernate h2 embeddable list expected "identifier"

问题描述

我正在尝试在我的员工实体中关联功能列表(可嵌入的功能)，H2对此表示不满，因为它希望有一个标识符"

I'm trying to associate a list of function (whom Embeddable) within my Employee Entity and H2 seems unhappy with this saying that it expected an "identifier"

由以下原因引起:org.h2.jdbc.JdbcSQLException:SQL语句中的语法错误" 创建表EMPLOYEE_FUNCTIONS( EMPLOYEE_EMPLOYEEID VARCHAR(255)非空， 活动布尔值不为NULL， DEPARTMENTNUMBER INTEGER NOT NULL， 说明VARCHAR(255)， ORDER [*] INTEGER NOT NULL )"；预期的标识符"；

Caused by: org.h2.jdbc.JdbcSQLException: Syntax error in SQL statement " CREATE TABLE EMPLOYEE_FUNCTIONS ( EMPLOYEE_EMPLOYEEID VARCHAR(255) NOT NULL, ACTIVE BOOLEAN NOT NULL, DEPARTMENTNUMBER INTEGER NOT NULL, DESCRIPTION VARCHAR(255), ORDER[*] INTEGER NOT NULL ) "; expected "identifier";

问题是我已经在另一个项目中做到了，我不明白为什么它不起作用.

The thing is I already done that with an other project and I don't see why it doesn't work.

Employee.java

Employee.java

@Entity
public class Employee extends AbstractScheduleEntity<EmployeeSchedule> {
    public static final String ACOMBA_UNIQUE_FIELD = "acombaUnique";

    @Id
    @GenericGenerator(name = "sequence_id", strategy = 
    "ca.tecsar.core.sql.ServerSequenceGenerator")
    @GeneratedValue(generator = "sequence_id")
    @Column(name = "EmployeeID", unique = true, nullable = false)
    private String employeeID;
    @ElementCollection
    private List<Function> functions;

    //getter and setter
}

Function.java

Function.java

@Embeddable
public class Function implements Serializable {
    private int order;
    private boolean active;
    private String description;
    private int departmentNumber;

    //getter and setter
}

我删除了Employee中不必要的一些属性. 可能导致此错误的原因是什么?是因为我在Employee中有一个String作为标识符吗?如果是这样，我如何告诉Hibernate添加Employee_EmployeeID作为标识符? 谢谢

I removed a few properties in Employee that wasn't necessary. What may cause this error? Is it because I have a String as identifier in my Employee? If so how can I tell to Hibernate to add Employee_EmployeeID as identifier? Thanks

推荐答案

原来我很笨，并命名为"Order"列.想知道为什么H2不开心:upside_down:

Turns out I was being dumb and named a column "Order". Wonder why H2 wasn't happy :upside_down:

将变量名更改为其他名称，然后它起作用了！

Changed the variable name to something else and it worked!
