Hibernate. PSQLException: bad value for type int : admin
提问by Marco A. Braghim
Well I have a desktop application with JAVA and Hibernate 4.3.1. For now I have just two entities (User and Role).
好吧，我有一个带有 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）。
User
用户
...
@ManyToOne(fetch = FetchType.LAZY)
@Fetch(FetchMode.JOIN)
@JoinColumn(nullable = false, name = "fk_role")
private Role fk_role;
...
Role
角色
...
@Column(name = "admin", nullable = false)
@Type(type = "org.hibernate.type.BooleanType")
private boolean admin = false;
...
I have tried instead
我已经尝试过了
@Type(type = "org.hibernate.type.BooleanType")
this.
这。
@Type(type = "org.hibernate.type.NumericBooleanType")
and
和
@Type(type = "org.hibernate.type.YesNoType")
and
和
@Type(type = "org.hibernate.type.TrueFalseType")
As shown here: http://docs.jboss.org/hibernate/core/3.6/reference/en-US/html/types.html#types-value-basic
如下所示：http: //docs.jboss.org/hibernate/core/3.6/reference/en-US/html/types.html#types-value-basic
And nothing. =/
没别的了。=/

=( In the database, the type for column admin is boolean and I use Postgres 9.3. When I run this, I got the following: --

Caused by: org.postgresql.util.PSQLException: bad value for type int: admin
引起：org.postgresql.util.PSQLException：int 类型的错误值：admin
回答by Marco A. Braghim
Finally I found the error!
最后我发现了错误！
The error message that Hibernate was returning to me was "bad value for type int: admin", but that was notthe problem. This message was completely crazy in relation to the issue. The real problem was that in the database my primary key (pk_role) is a VARCHAR type, but in my entity I put as an INTEGER type.
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。这条消息对于这个问题完全是疯狂的。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，我将其放置为 INTEGER 类型。
After Vlad try to help me supposing the version of the jdbc driver, I put the configuration exactly equal to other project I have working pretty well and the error was the same, so I knew that the error was in my own code, for sure.
在 Vlad 尝试帮我假设 jdbc 驱动程序的版本后，我将配置完全等同于我工作得很好的其他项目并且错误是相同的，所以我知道错误是在我自己的代码中，当然。

If you have a separate database schema, just change the column type to boolean:
如果您有单独的数据库架构，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;
and then the mapping is as simple as this:
然后映射就像这样简单：
@Column(name = "admin", nullable = false)
private boolean admin = false;
