插入数据时JBoss休眠错误

Question

我配置了一个数据源并在persistence.xml中使用：

<persistence-unit name="myds">
      <jta-data-source>java:jboss/datasources/BBDS</jta-data-source>
      <properties>         
         <property name="hibernate.hbm2ddl.auto" value="create-drop" />
         <property name="hibernate.show_sql" value="false" />
      </properties>
   </persistence-unit>

我测试了一下，显示连接成功：

http://localhost:9990/console

在我的 Web 应用程序中，我有一个 import.sql 用于初始加载到数据库：

insert into Member (id, name, email, phone_number) values (0, 'John Smith', 'john.smith@mailinator.com', '2125551212') 

我正在使用 Wildfly 服务器，并尝试启动我的应用程序，但收到此错误消息。似乎无法加载初始会员记录。

我有一个具体的问题：

1) 数据源名称为“BBDS”。在运行应用程序之前，我应该在 MySql (MariaDB) 中创建数据库名称“BBDS”吗？我以为数据库和表会因为

而自动创建和销毁

2）“未选择数据库”，在哪里指定数据库？

Answer 1

这样的配置不会自动为您创建数据库。在部署此应用程序之前，必须在 wildfly 中配置 BombwordDS 数据源，并且它应该引用现有数据库。

如果您暂时不关心数据的持久化，而只想测试您的应用程序/架构，您也可以使用 Wildfly 包含的 ExampleDS，它使用 H2 内存数据库。
