我有一台使用jax-rs的服务器，除了我尝试在其上运行Junit测试时，它的工作方式与我希望的完全相同。
我有一个RepositoryService类，该类具有要测试的方法，并且它使用EntityManagerFactory访问数据库。
每当我尝试在测试中实例化此类时，都会给我以下错误。
我认为需要注意的重要一点是，只要我正常运行应用程序，一切都可以正常运行，这些错误仅在我尝试运行任何测试时才会发生。
我尝试使用Google搜索所有“ Caused by：”行，但无济于事。
这是我用于配置持久性单元的persistence.xml，因为持久性单元似乎是错误的出处：
<?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="userPU" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
<non-jta-data-source>java:comp/env/jdbc/ziggoDb</non-jta-data-source>
<properties>
<property name="javax.persistence.sql-load-script-source" value="sql/data.sql"/>
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>
<property name="hibernate.show_sql" value="true"/>
</properties>
</persistence-unit>
</persistence>
这些是错误：
