无法从无处构建Hibernate SessionFactory异常

Question

每次我想部署我的应用程序时,都会出现一个奇怪的错误.我正在使用IntelliJ IDEA 2016.3.

我的应用程序是使用JSF,EJB和JPA(Hibernate)的Java WEB应用程序.所有的库都是由IDEA下载的(在这个项目中没有Maven),所有依赖项都附带.war文件.我正在Windows 10上部署到TomEE 7.0.2.

以下是部署中涉及的配置文件:resources.xml

<?xml version="1.0" encoding="UTF-8"?>
<resources>
    <Resource id="my_internet_shop_db" type="javax.sql.DataSource">
        JdbcDriver  com.mysql.jdbc.Driver
        JdbcUrl jdbc:mysql://localhost:3306/my_internet_shop?autoReconnect=true&amp;useSSL=true
        UserName root
        Password alpine
        validationQuery = SELECT 1
        JtaManaged true
    </Resource>
</resources>

persistence.xml中

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="2.0">

    <persistence-unit name="my_internet_shop" transaction-type="JTA">

        <properties>

            <property name="hbm2ddl.auto" value="update"/>
        </properties>
    </persistence-unit>
</persistence>

这只是提到例外的一小部分.以下是完整的堆栈跟踪和服务器日志

所有数据库内容和JPA映射都可以.经过双重检查,精制至完美.事实上,我能够在Tomcat 8.5.6服务器上运行我的应用程序,但它不支持EJB,所以我需要TomEE.

这里的根本重复是java.lang.IllegalStateException: On a thread without an initialized context nor a classloader mapping a deployed app.它出现在我的所有Hibernate-JPA项目中(即使是只有一个实体且没有错误空间的简单测试),所以我认为这是真正的服务器端配置问题.

但是,我无法在StackOverflow和互联网上找到任何有关此异常的线索.

我期待着你的帮助,很乐意得到任何帮助和建议.

Answer 1

您可以添加persistence.xml

<property name="tomee.jpa.factory.lazy" value="true" />

要么

<property name="tomee.jpa.cdi" value="false" />

如果您不需要CDI/JPA集成

编辑:第一个将使工厂在运行时首次使用时创建,第二个将禁用cdi.这两项工作都会导致您在启动期间初始化JPA时不需要CDI(在启动cdi之前创建工厂因为cdi可以依赖它 - 鸡蛋问题)
