hibernate。 PSQLException：int类型的错误值：admin
好吧，我有一个使用JAVA和Hibernate 4.3.1的桌面应用程序。 现在我只有两个实体（用户和角色）。
用户
... @ManyToOne(fetch = FetchType.LAZY) @Fetch(FetchMode.JOIN) @JoinColumn(nullable = false, name = "fk_role") private Role fk_role; ... 角色
... @Column(name = "admin", nullable = false) @Type(type = "org.hibernate.type.BooleanType") private boolean admin = false; ...
我试过了
@Type(type = "org.hibernate.type.BooleanType")
这个。
@Type(type = "org.hibernate.type.NumericBooleanType")
和
@Type(type = "org.hibernate.type.YesNoType")
和
@Type(type = "org.hibernate.type.TrueFalseType")
如下所示： http ： //docs.jboss.org/hibernate/core/3.6/reference/en-US/html/types.html#types-value-basic
没别的了。 = /
我也试过了： http ： //alenovarini.wikidot.com/mapping-a-custom-type-in-hibernate
=（在数据库中，列admin的类型是布尔值，我使用Postgres 9.3 。当我运行它时，我得到以下内容： –

引起：org.postgresql.util.PSQLException：int类型的错误值：admin
最后我发现了错误！
Hibernate返回给我的错误消息是“类型int：admin”的错误值，但这不是问题。 关于这个问题，这条消息非常疯狂。 真正的问题是在数据库中我的主键（pk_role）是VARCHAR类型，但在我的实体中我将其作为INTEGER类型。
在Vlad尝试帮我假设jdbc驱动程序的版本之后，我把配置完全等于我工作得很好的其他项目并且错误是一样的，所以我知道错误是在我自己的代码中，当然。
如果您有单独的数据库模式，只需将列类型更改为boolean ：
ALTER TABLE role ALTER COLUMN admin TYPE boolean default false; ALTER TABLE role MODIFY admin NOT NULL;
然后映射就像这样简单：
@Column(name = "admin", nullable = false) private boolean admin = false;
