Spring 和 Hibernate，找到位，预期为 TINYINT(1) DEFAULT 0

Question

在数据库中:有一个字段的类型是TINYINT(1)，默认值为0。在Model中它被定义为TINYINT(1) DEFAULT 0。但是它给出了如下错误:

错误

[jar:file:/C:/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/NetaCommerceFrameworkAdmin/WEB-INF/lib/NetaCommerceFramework-0.0.1-SNAPSHOT.jar!/com/netasoft/commerce/framework/lang/dao/LangDaoImpl.class]: Unsatisfied dependency expressed through constructor argument with index 0 of type

Found: bit, expected: TINYINT(1) DEFAULT 0

模型定义

@Column(name="alerted", columnDefinition = "TINYINT(1) DEFAULT 0")
private int alerted;

public int getAlerted() {
    return alerted;
}

public void setAlerted(int alerted) {
    this.alerted = alerted;
}

方言版本:

2013-01-17 08:45:36,920 INFO [org.hibernate.cfg.SettingsFactory] - Database ->
       name : MySQL
    version : 5.0.96-community-nt

它也在服务器和另一台计算机上运行。但是，在我的计算机和只是为了尝试而安装的新计算机中，它给出了相同的错误。我在谷歌上搜索了几天，无法弄清楚是什么原因导致了这个问题。尝试在模型中使用 boolean columnDefinition 并更改 MySqlDialect 定义，但没有任何变化。甚至错误消息都是一样的。

使用 BIT 作为列定义

这对我有用:

@Column(name = "my_field",columnDefinition = "BIT")
private int myField;
