hibernate - 使用 Hibernate 在 Wildfly 上使用 JPA 创建表失败

Question

我使用 JPA 在使用 hibernate 安装的 Wildfly 8.0 的内置 H2 数据库上创建一个表，但失败并显示以下错误消息:

该问题似乎与未找到表“JPA_USER”行相关； SQL语句:

insert into JPA_User (employeeId, first_name, last_name, salary)
values (null, ?, ?, ?) [42102-173]

但我希望 jPA 为我创建表 我的 persistence.xml 如下所示:

<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="ExampleDS">
<jta-data-source>java:jboss/datasources/ExampleDS</jta-data-source>
<properties>
      <property name="hibernate.hbm2dll.auto" value="create"/>
      <property name="hibernate.connection.username" value="sa"/>
      <property name="hibernate.connection.driver_class" value="org.hsqldb.jdbcDriver"/>
      <property name="hibernate.connection.password" value="sa"/>
      <property name="hibernate.show_sql" value="true"/>
      <property name="hibernate.format_sql" value="true"/>
    </properties>
</persistence-unit>
</persistence>

我使用默认数据源，该数据源与 h2 数据库关联。

有谁知道这里的问题是什么？

Answer 1

您的属性名称不正确。它是 ddl 而不是 dll。

<property name="hibernate.hbm2ddl.auto" value="create"/>
