    项目功能:

    连接MySql数据库,向数据库插入一条数据

 

    项目结构:

 

    DEBUG信息:

    

DEBUG [main] - Destroying singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@67b92f0a: defining beans 
[org.springframework.context.support.PropertySourcesPlaceholderConfigurer#0,studentService,studentDao,dataSource]; root of factory hierarchy

    juint信息:

org.springframework.beans.factory.BeanCreationException:
Error creating bean with name 'studentService' defined in class path resource [applicationContext.xml]:
Cannot resolve reference to bean 'studentDao' while setting bean property 'studentDao';
nested exception is org.springframework.beans.factory.BeanCreationException:
Error creating bean with name 'studentDao' defined in class path resource [applicationContext.xml]:
Cannot resolve reference to bean 'dataSource' while setting bean property 'dataSource';
nested exception is org.springframework.beans.factory.BeanCreationException:
Error creating bean with name 'dataSource' defined in class path resource [applicationContext.xml]:
Error setting property values; nested exception is org.springframework.beans.PropertyBatchUpdateException;
nested PropertyAccessExceptions (1) are: PropertyAccessException 1: org.springframework.beans.MethodInvocationException:
Property 'driverClassName' threw exception; nested exception is java.lang.IllegalStateException: Could not load JDBC driver class [${jdbc.driverClass]

 分析:

  1.配置文件出错。

  (1)检测jdbc.properties————————————没有错误

  (2)检测applicationContext.xml————————没有错误

  2.JAR包错误

  (1)重新导包————————————————解决错误,成功连接数据库,插入数据。

 

    问题原因:

    产生错误时使用的Jar包:                                          重新导入的Jar包:

   

 

   缺少mysql-connector-java-5.1.13-bin.jar包!!

 

   所以报的是无法找到驱动。
