连接到 oracle 数据库的 Junit 问题

Question

我正在尝试进行测试以连接到我的数据库并写入其中。这是测试代码的一部分 class: public class

     ManagerTest {
            @Test
            public void testSave() {
                EntityManager entityManager = EntityManagerUtil.getEntityManagerFactory().createEntityManager();
         }
     }

这是 EntityManagerUtil：

public class EntityManagerUtil {

    private static EntityManagerFactory entityManagerFactory = null;

    static {
        try {
        entityManagerFactory = Persistence.createEntityManagerFactory("SomeName");
        }catch (Exception e) {
            e.printStackTrace();
        }
    }

    public static EntityManagerFactory getEntityManagerFactory() {
        return entityManagerFactory;
    }
}

这是persistence.xml

<?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="SomeName" transaction-type="RESOURCE_LOCAL">
        <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>

我无法显示声明和属性，但我 100% 确定它们设置正确。

这是我得到的错误：

Answer 1

经过几个小时的调试和搜索，我发现我在另一个项目中使用了相同的名称作为持久性单元。棘手的部分是我的项目依赖于另一个项目，因此当尝试使用 xml 创建工厂时，它正在使用另一个文件，该文件具有 <jta-data-source> 标签。此标记负责错误消息。所以当我更改名称时一切正常。
