Question

我无法连接到数据库而我找不到问题

持久性文件：

<?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://xmlns.jcp.org/xml/ns/persistence/persistence_2_0.xsd ">
  <persistence-unit name="UP_GAB" transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <properties>
            <property name= "hibernate.show_sql" value= "true"/>
            <property name="hibernate.hbm2ddl.auto" value="validate" />
            <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" />
        </properties>
    </persistence-unit>
</persistence>

contexte file：

<?xml version="1.0" encoding="UTF-8"?>

</beans>

数据库信息：

连接名称：Gab
  用户名：issam
  主机名：localhost
  港口：1521
  SID：Gab

这是pom.xml文件中的依赖项：

       <dependency>
            <groupId>com.oracle</groupId>
            <artifactId>ojdbc14</artifactId>
            <version>10.2.0.4.0</version>
        </dependency>

注意：我有Oracle 11 g而不是phpmyadmin

感谢您的帮助！

Answer 1

财产应该是：
property name =＆＃34; hibernate.hbm2ddl.auto＆＃34;值=＆＃34;创建＆＃34;

为什么数据库Oracle 11g中的表不是由Hibernate创建的（通过Spring＆amp; Maven）？
