枚举Java未保存为带枚举注释的字符串

Question

我无法创建枚举以在MySQL DB中保存为字符串.我有一个带有字段的MySQL表:

status varchar(50)

枚举

public enum Status {OPEN, CLOSED, CANCELLED, DONE}

实体

@Column(name="status", nullable=false)
private Status status;

@Enumerated(EnumType.STRING)
public Status getStatus() {return status;}

当我启动我的应用程序时,我在获取数据时出现以下错误: SQLException:getInt()'OPEN'的值无效

另外我无法创建实体,我有一个SQLGrammarError.它试图用status = OPEN而不是status ='OPEN'来保存对象.

我按照文档JavaDoc Persistence Enum 编写了 本教程Jpa和Enums

通过在属性状态上添加@Enumerated(EnumType.STRING).提取错误不存在,但我仍然有相同的错误来创建实体.

Answer 1

移动@Enumerated到现场

@Column(name="status", nullable=false)
@Enumerated(EnumType.STRING)
private Status status;

编辑

您获得的例外与枚举无关.在MySQL中lock是一个保留字,你必须将它的名字改为其他东西.
