编辑：已发现此问题的解决方案，问题是在persistence.xml中，data-source-name需要以java：comp / env /为前缀，如下所示：java：comp / env / jdbc / TSDB
我知道这是一个记录良好的问题，然而，经过许多不同的尝试和充分的阅读，我仍然无法配置Hibernate使用的数据源。
我正在尝试开发一个Tomcat应用程序服务器，它使用hibernate连接到MySQL服务器。
我正在使用Eclipse版本：2018-12（4.10.0）Hibernate：5.4.1.Final Mysql连接器：8.0.14 SERVER：Apache Tomcat / 9.0.14
数据源在server.xml中定义：
<GlobalNamingResources>
<Resource auth="Container" driverClassName="com.mysql.jdbc.Driver" maxTotal="100"
maxIdle="30" maxWaitMillis="10000" minIdle="5" name="jdbc/TSDB" password="PASSWORD"
type="javax.sql.DataSource" url="jdbc:mysql://localhost:3306/tstest?allowPublicKeyRetrieval=true" username="USERNAME"/>
</GlobalNamingResources>
Veb.hml：
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd" id="WebApp_ID" version="4.0">
<resource-ref>
<res-ref-name>jdbc/TSDB</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
</web-app>
context.xml中：
<Context>
<ResourceLink name="jdbc/TSDB" global="jdbc/TSDB" type="javax.sql.DataSource" />
</Context>
persistence.xml中：
<?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="TsPersistence" transaction-type="JTA">
<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
<jta-data-source>jdbc/TSDB</jta-data-source>
<!-- Entity Classes Mappings -->
<class>com.ts.hibernate.entities.User</class>
<!-- EO Entity Classes Mappings -->
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>
</properties>
</persistence-unit>
</persistence>
然后，当我尝试在Web侦听器中创建实体管理器时：
@WebListener
public class HibernateSessionFactoryListener implements ServletContextListener {
public final Logger logger = LogManager.getLogger(HibernateSessionFactoryListener.class);
public void contextInitialized(ServletContextEvent servletContextEvent) {
EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("TsPersistence");
servletContextEvent.getServletContext().setAttribute("EntityManagerFactory", entityManagerFactory);
logger.info("Entity Manager Configured Successfully!");
}
我收到以下错误：

我需要创建任何其他配置吗？任何帮助将不胜感激，谢谢！
在GlobalNamingResource文件中声明的server.xml元素与Docs文件中声明的resource-ref等效（web.xml）。我要说删除web.xml里面的那个
<resource-ref>
<res-ref-name>jdbc/TSDB</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
