如何解决冬眠PSQLException：类型为int的值错误：admin
终于我发现了错误！
Hibernate返回给我的错误消息是“类型int的错误值：admin”，但这 问题。关于此问题，此消息是完全疯狂的。
在Vlad尝试帮助我假设jdbc驱动程序的版本之后，我将配置与我可以正常工作的其他项目完全相同，并且错误是相同的，因此我肯定知道该错误是在我自己的代码中。
解决方法
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：-
