工具:读取错误模式--可能是JDBC驱动程序问题

Question

你好，我正在尝试使用JBoss Hibernate工具进行逆向工程。我正在使用来自eclipse市场的eclipse luna和最新的hibernate jboss工具。当我试图配置hibernate工具配置时，在配置完成后，当我展开树并展开database节点时，它会生成以下错误：

<Reading Schema Error: Could not get list of suggested identity strategies from database. Probably a JDBC Driver Problem>

堆栈跟踪：

我与eclipse的数据库连接是成功构建的，因为在eclipse Database explore的帮助下，成功地建立了连接，并显示了所有表。我正在使用Hibernate 4.3和最新的MySQL driver 5.1.31。下面是我的配置的屏幕截图。

以下是我的hibernate.cfg.xml文件：

<hibernate-configuration>
<session-factory>
    <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
    <property name="hibernate.connection.password">password</property>
    <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/nit-empirecl-test</property>
    <property name="hibernate.connection.username">root</property>
    <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
</session-factory>
</hibernate-configuration>

Answer 1

我找到了解决方案，问题在于数据库名。我不知道，但是hibernate jboss工具，在数据库名上不支持( - )连字符。当我用下划线更改名称时，配置将成功运行。

Answer 2

您应该设置hibernate默认架构(用于sql server)。

<property name="hibernate.default_schema">dbo</property>

Answer 3

我也有同样的问题，但在和数据库名称中没有"-“。您可以尝试设置“可选”属性hibernate.default_schema。
