做SSH练习的时候，JUunit运行遇到报错信息

提示说是applicationcontext文件中的jdbcUrl信息错误，可是xml文件中的url再三确认是没有错的，不知道怎么回事？ 最下面贴上applicationContext.xml中的数据源配置信息

org.sPRingframework.beans.factory.BeanCreationException: Error creating bean with name 'db' defined in class path resource [applicationContext.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'jdbcUrl' of bean class [org.springframework.jdbc.datasource.DriverManagerDataSource]: Bean property 'jdbcUrl' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

applicationContext.xml 文件中的配置信息，Oracle的信息注掉了，现在用的是MySQL数据库
