好吧，我有一个使用JAVA和Hibernate 4.3.1 的桌面应用程序。目前，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;

...

我尝试了

@Type(type = "org.hibernate.type.BooleanType")

这。

@Type(type = "org.hibernate.type.NumericBooleanType")

和

@Type(type = "org.hibernate.type.YesNoType")

和

@Type(type = "org.hibernate.type.TrueFalseType")

如此处所示：http :
//docs.jboss.org/hibernate/core/3.6/reference/zh-CN/html/types.html#types-
value-basic

没别的了。= /

我也尝试过：http : //alenovarini.wikidot.com/mapping-a-custom-type-
in​​-hibernate

=（在数据库中，admin列的类型为boolean，我使用Postgres 9.3 。运行此命令时，得到以下信息：-
