java.lang.Exception:不是实体：class com.domain.package.User

我正在将实体映射从annotations应用程序迁移到hbm.xml

我出错了，没有找到解决方案。谢谢

java.lang.Exception: Not an entity: class com.enterprise.package.user.domain.User

我在resources文件夹中有hibernate.cfg.xml，在一个包中有User.hbm.xml，在另一个包中有User.class

User.hbm.xml

<?xml version = "1.0" encoding = "utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD//EN"
        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

    <class name="com.enterprise.package.role.domain.User" table="user">

            <generator class="identity" />
        </id>
        <property name="username" column="username" type="java.lang.String" unique="true"/>
        <property name="password" column="password" type="java.lang.String"/>
        <many-to-one name="role" column="role_id" class="com.enterprise.package.role.domain.Role" not-null="true"/>
    </class>
</hibernate-mapping>

hibernate.cfg.xml

com.mysql.cj.jdbc.Driver
jdbc：mysql://localhost:3306/db
根

真的

我认为User.hbm.xml中User类的包可能是错误的（我们在您的代码片段中看不到这个类的包）

在User.hbm.xml中，而不是

com.enterprise.package.role.domain.User

可能是

---

com.enterprise.package.user.domain.user

我刚刚意识到复制和粘贴错误，两个实体都在com.enterprise.package.user.domain中*是的，它发生了。。。如果这是问题所在，你可以接受我的答案，thkx
