我正在尝试使用Spring和Hibernate以及MySQL数据库配置Java MVC webapp,但是当我运行服务器时出现此错误,我不知道是什么问题.

我不知道错误在哪里.这是我的applicationContext.xml.错误似乎在dataSource bean中.
这是我的jdbc.properties
hibernate.generate_statistics = true
hibernate.show_sql = true
jdbc.driverClassName=com.mysql.jdbcDriver
jdbc.url=jdbc:mysql://localhost:3306/baseDeDatos
jdbc.username=miUsuario
jdbc.password=miContrasena
hibernate.dialect=org.hibernate.dialect.MySQLDialect
我有这个jar来加载类.它们中的某些东西(比如jpa-api.jar)我认为它不是必要的而且其他的都是重复的,但我在其他项目中已经开始制作它,我还没有删除它：

有人可以帮我解决这个问题吗？我使用Tomcat 7在Eclipse中运行它.
谢谢！
你在这里得到了错误的驱动程序名称：
jdbc.driverClassName=com.mysql.jdbcDriver
它应该是：
jdbc.driverClassName=com.mysql.jdbc.Driver
请注意.在jdbc和Driver之间.
诊断类似事物的方法是查看它找不到的类：
Cannot load JDBC driver class 'com.mysql.jdbcDriver'
这已经看起来很可疑,因为名称jdbcDriver不遵循Java命名约定.那么在那时你再仔细检查它应该是什么 – 例如通过查看jar文件 – 并修复配置.
正如评论中所指出的那样,我认为在类路径上拥有同一个jar文件的多个版本并不是一个好主意 – 我看不出结果很好.
