hibernate4 异常

 最近学习hibernate4遇到的问题记录一下，数据库使用 的是mysql5.6.23

1.Exception in thread "main" org.hibernate.MappingException: Could not instantiate id generator [entity-name=com.share.domain.User]

at org.hibernate.id.factory.internal.DefaultIdentifierGeneratorFactory.createIdentifierGenerator(DefaultIdentifierGeneratorFactory.java:123)

Caused by: org.hibernate.MappingException: Could not interpret id generator strategy [increament]

... 5 more

这个问题产生的原因是实体类User中的主键id生成策略导致

        @Id

@GenericGenerator(name = "generator", strategy = "increament")//错误位置

// id属性自增

@GeneratedValue(generator = "generator")

@Column(name = "id", nullable = false, unique = true)

private long id;

将上面的increament改为native即可
