注释@Type（type =“pg-uuid”）类“pg-uuid”未找到异常

标签： java spring postgresql hibernate uuid

我在尝试使用注释@Type（type =“pg-uuid”）时遇到了一些麻烦。它抛出了这个例外：

Caused by: java.lang.ClassNotFoundException: Could not load requested class : pg-uuid

我的所有实体都在这个结构中：

package entv.enterprise.application.core.entity;

import java.io.Serializable;

import org.hibernate.annotations.Type;
import org.springframework.format.annotation.DateTimeFormat;

    this.username = username;
}

public String getPassword() {

}

@Override
public int hashCode() {
    final int prime = 31;
    int result = 1;
    result = prime * result + ((id == null) ? 0 : id.hashCode());

        return true;
    if (obj == null)
        return false;
    if (getClass() != obj.getClass())
        return false;
    User other = (User) obj;
    if (id == null) {
        if (other.id != null)
            return false;
    } else if (!id.equals(other.id))
        return false;
    return true;
}
}

如果我在type =中使用“org.hibernate.type.PostgresUUIDType”，它会抛出：     没有JDBC类型的Dialect映射：1111

编辑08/12/2016：我不确定为什么，但在项目清理后问题似乎已经解决了。

1 个答案:

答案 0 :(得分：0)

改为使用此annotation 

@org.hibernate.annotations.Type(type = "org.hibernate.type.PostgresUUIDType")
