我一直在寻找答案，但没有找到解决方案。我正在使用 JSF2 和 Hibernate 开发简单的网络应用程序。这是我第一次使用 Hibernate，我在配置方面遇到了很多问题。我当前的问题是：我将 mysql 连接器配置为 JBoss7.1 模块中的模块。然后我创建了数据源并将 mysql-connector-java-5.1.20-bin.jar 添加到类路径中（它位于 .war 的 WEB-INF/lib 目录中）。启动 JBoss 后，我收到以下日志：
23:44:07,497 INFO [org.jboss.as.connector.subsystems.datasources] (ServerService Thread Pool -- 27) JBAS010403: Deploying JDBC-compliant driver class org.h2.Driver (version 1.3)
23:44:07,603 INFO [org.jboss.as.connector.subsystems.datasources] (ServerService Thread Pool -- 27) JBAS010404: Deploying non-JDBC-compliant driver class com.mysql.jdbc.Driver (version 5.1)
...

23:44:21,535 INFO [org.hibernate.service.jdbc.connections.internal.DriverManagerConnectionProviderImpl] (MSC service thread 1-3) HHH000046: Connection properties: {user=root}
23:44:21,556 WARN [org.hibernate.engine.jdbc.internal.JdbcServicesImpl] (MSC service thread 1-3) HHH000342: Could not obtain connection to query metadata : No suitable driver found for jdbc:mysql://localhost/testdb
然后部署应用程序并成功启动服务器。当我尝试调用方法试图持久化我获得的一些数据时
org.hibernate.exception.JDBCConnectionException: Could not open connection
and
java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost/testdb
我确定mysql-connector-java-5.1.20-bin.jar 位于war 文件的WEB-INF/lib 目录中。任何想法我在这里想念什么？MySQL 服务器版本是 5.1.63，但我认为这里不相关。非常感谢！
编辑：端口没问题，我检查了两次；-) 但是，现在我真的很困惑，因为代码在容器外运行良好。我创建了使用相同代码的类（HIbernateUtil 获取会话工厂）并且没有异常，并且数据被插入到数据库中。您能否解释一下为什么它以这种方式工作，以及为什么它不能在容器下工作？以及如何解决这个问题，因为我不知道......非常感谢！

我使用的是 Hibernate 4.1.3，我必须添加 Hibernate jar 作为外部 jar 来构建路径，即使在 modules/org/hibernate/main 更改之后（我更改了 module.xml 并替换了旧 jar）。更改之后，我在部署期间遇到了不同的异常： .org.hibernate.service.classloading.spi.ClassLoadingException: Specified JDBC Driver com.mysql.jdbc.Driver class not found 在 Jboss 的日志中提到 com.mysql.jdbc.Driver已部署。帮助！
