类是托管的，但未在 persistence.xml 文件中列出

我在我的项目中遇到以下异常：

类“com.testApp.domain.Register”被管理，但未在 persistence.xml 文件中列出

My persistence.xml文件看起来像这样：

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0"
    xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">

    <persistence-unit name="default" transaction-type="RESOURCE_LOCAL">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <properties>
            <property name="hibernate.archive.detection" value="class, hbm" />
            <property name="hibernate.show_sql" value="true" />
            <property name="hibernate.format_sql" value="true" />

            <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect" />
            <property name="hibernate.hbm2ddl.auto" value="update" />

            <property name="hibernate.connection.driver_class" value="org.hsqldb.jdbcDriver" />
            <property name="hibernate.connection.url" value="jdbc:hsqldb:mem:." />
            <property name="hibernate.connection.username" value="SA" />
            <property name="hibernate.connection.password" value="" />

            <property name="hibernate.c3p0.min_size" value="5" />
            <property name="hibernate.c3p0.max_size" value="20" />
            <property name="hibernate.c3p0.timeout" value="300" />
            <property name="hibernate.c3p0.max_statements" value="50" />
            <property name="hibernate.c3p0.idle_test_period" value="3000" />

        </properties>
    </persistence-unit>

</persistence>

我已经尝试过这个post https://stackoverflow.com/questions/2242637/class-model-address-is-listed-in-the-persistence-xml-file-but-not-mapped and this https://stackoverflow.com/questions/18051055/must-every-entity-bean-be-registered-in-persistence-xml，两者都建议手动或自动将类添加到persistence.xml。其他人说这是与 eclipse 相关的问题，可以通过清理或重新打开项目来解决。但是，我希望 hibernate 自动检测这些类，而不是手动将它们添加到我的persistence.xml.

对于解决方案和解决我的错误有什么建议吗？

感谢您的回复！

如果您使用的是 Eclipse：(1) 选择：(您的项目) -> 属性 -> JPA； （2）查找“持久类管理”并选择“自动发现带注释的类”选项； (3) 按“应用”。
