Spring 春季及；休眠，找到位，应为TINYINT（1）默认值0

在数据库中：有一个字段的类型为TINYINT（1），默认值为0。在模型中，它被定义为TINYINT（1）默认值0。但是，它会产生如下错误：

错误

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：

它正在服务器和另一台计算机上运行。然而，在我的电脑和新安装的电脑，只是为了尝试它给出了相同的错误。我在谷歌上搜索了好几天，不知道是什么原因导致了这个问题。尝试在模型中使用布尔列定义并更改mysqldialent定义，但没有任何更改。甚至错误消息都是相同的。

将@Type注释添加到警报字段，如下所示：

@org.hibernate.annotations.Type(type="true_false")
@Column(name="alerted", columnDefinition = "TINYINT(1) DEFAULT 0")
private int alerted;

您可以使用tinyInt1isBit=false mysql驱动程序参数。i、 e.jdbc：mysql://localhost?tinyInt1isBit=false

这将防止驱动程序将tinyint（1）列报告为java.sql.Type.BIT

---

但是，如果布尔字段在数据库中也表示为tinyint（1），则可能会出现布尔字段问题。

使用位作为列定义

这对我很有用：

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