无法加载JDBC驱动程序.为什么？(春,休眠)

我已经在两周前创建了一个程序(SPRING+ HIBERNATE)Maven,现在它在加载JDBC驱动程序时遇到了问题(直到现在才发生).所以,我的pom.xml文件看起来像这样:

    4.0.0
    com.spring.hib
    HibPav
    1.0-SNAPSHOT

    

    
        org.springframework
        spring
        2.5.6
    


    mysql
    mysql-connector-java
    5.1.27


    
      org.springframework
      spring-hibernate3
      2.0.5
    

        
        dom4j
        dom4j
        1.6.1
    

    
    javax.transaction
    jta
    1.1
    

     
      org.springframework
      spring-jdbc
      3.2.5.RELEASE
       

    
          org.hibernate
          hibernate-core
          4.2.7.Final 
    


    

看来这个文件很清楚.但是在我尝试创建dataSourcebean 时,无法加载JDBC驱动程序的主要问题是什么.

其他文件:

数据源文件

    
        properties/database.properties
    



    
    
    
    

属性文件

jdbc.driverClassName=com.mysql.jdbc.Driver;
jdbc.url=jdbc:mysql://localhost/mydb
jdbc.username=myinfuser
jdbc.password=myinfuserpw

错误:
