Oracle 数据库版本： 11.2.0.

驱动程序版本是否需要与数据库版本匹配？

编辑：

  1. 如何跟踪程序从哪个文件路径加载驱动程序？这增强了我找到根本原因的能力。谢谢。

  2. 如何启用 ojdbc6-g 日志记录？我试图遵循这个Oracle_JDBC但我不知道如何完成它。如何全局设置 Java 系统属性？我知道环境变量可能不是一个好的选择。还有其他想法吗？我只想在使用此java时将-Doracle.jdbc.Trace=true和-Djava.util.logging.config.file添加到jvm创建中。它是否在启动期间设置了 oracle 数据库？

  3. 如何启用休眠日志记录？

  4. 我使用的是Hibernate-4.1.1和JBoss 7.1。

请帮忙。

谢谢。


答案 1

“ojdbc.jar”不在应用程序服务器中。CLASSPATH

只需告诉我们它是哪个应用程序服务器，我们就会告诉您驱动程序应该放在哪里。

编辑：我看到标签jboss，所以它必须放在文件夹中"$JBOSS_HOME/server/default/lib/"


答案 2

“没有合适的驱动程序”通常意味着你提供用于连接的 URL 语法不正确，或者根本没有加载驱动程序。JDBC

当调用 getConnection 方法时，将尝试从初始化时加载的驱动程序和使用与当前小程序或应用程序相同的类加载器显式加载的驱动程序中找到合适的驱动程序。（使用DriverManagerClass.forName())

例如

import oracle.jdbc.driver.OracleDriver;

Class.forName("oracle.jdbc.driver.­OracleDriver");

还要检查您的类路径中是否有。我建议将物理位置放在项目的JBoss目录中。ojdbc6.jar.jar"$JBOSS_HOME/server/default/lib/"

编辑：

你最近提到过。hibernate

检查您的文件是否具有如下所示的连接属性：hibernate.cfg.xml

<property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<property name="hibernate.connection.url">jdbc:oracle:thin:@localhost:1521:orcl</property> 
<property name="hibernate.connection.username">scott</property>
<property name="hibernate.connection.password">tiger</property>
