您好我正在尝试使用JBoss Hibernate Tools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。当我尝试配置hibernate工具配置时,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>
堆栈追踪:

我的数据库与eclipse的连接是成功构建的,因为在Database explore
的帮助下,eclipse make connection成功并且还显示了所有表。我使用的是Hibernate 4.3
和最新的MySQL driver 5.1.31
。以下是我配置的屏幕截图。
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>

我找到了解决方案,问题在于数据库名称。我不知道,但是hibernate jboss工具,不支持数据库名称中的( - )
连字符。当我用下划线更改名称时,配置将成功运行。
答案 1 :(得分:4)
您应该设置hibernate
默认架构(对于sql server)
<property name="hibernate.default_schema">dbo</property>
答案 2 :(得分:1)
我使用以下JDBC驱动程序,并且问题得到解决。
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.47</version>
</dependency>
答案 3 :(得分:0)
我遇到了同样的问题,但是使用MS SQL Server而DB名称中没有“ - ”。 您可以尝试设置“可选”属性hibernate.default_schema。
