java - Glassfish 上的 Hibernate 不是实体异常

Question

我有以下问题:应用程序已成功部署，但每当我尝试执行查询时，结果都会像这样:

Caused by: java.lang.IllegalArgumentException: Not an entity: class javaeetutorial.addressbook.entity.Contact

这是我的配置:

持久性.xml

<persistence-unit name="address-bookPU" transaction-type="JTA">

<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
<jta-data-source>jdbc/PostgreSQLDataSource</jta-data-source>

<class>javaeetutorial.addressbook.entity.Contact</class>

<properties>
  <property name="hibernate.archive.autodetection" value="class, hbm"/>
  <property name="javax.persistence.schema-generation.database.action" value="drop-and-create"/>
  <property name="hibernate.transaction.jta.platform" value="org.hibernate.service.jta.platform.internal.SunOneJtaPlatform" />
  <property name="show_sql" value="true"/>
</properties>
</persistence-unit>

实体类当然是用@Entity注释的。

谁能帮我解决这个问题吗？

Answer 1

我花了两天时间找到了以下解决方案。1. 至少使用Hibernate 4.3.10:

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-entitymanager</artifactId>
        <version>4.3.10.Final</version>
    </dependency>

2.按如下方式更改 persistence.xml(架构 2.1，提供程序 <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider> ，两个属性 - 必须):

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
  <persistence-unit name="your_pu" transaction-type="JTA">
    <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
    <jta-data-source>jdbc/your_src</jta-data-source>
    <exclude-unlisted-classes>false</exclude-unlisted-classes>
    <properties>
        <property name="hibernate.archive.autodetection" value="class, hbm, jar"/>
        <property name="hibernate.transaction.jta.platform" value="org.hibernate.service.jta.platform.internal.SunOneJtaPlatform"/>
    </properties>
  </persistence-unit>
</persistence>
