有道翻译：

在上下文初始化时遇到的异常-取消刷新尝试:org.springframework.beans.factory.BeanCreationException:创建在类路径资源[applicationContext.xml]中定义名为“dataSource”的bean时出错:设置属性值时出错;嵌套的异常是org.springframework.beans.PropertyBatchUpdateException;嵌套的PropertyAccessExceptions(1)是:

PropertyAccessException: org.springframework.bean . methodinvocationexception: Property 'driverClassName'抛出异常;嵌套异常是java.lang.IllegalStateException: Could not load JDBC driver class [com.mysql.cj.jdbc.Driver]

 因为jdbcTempate拼写错误

 数据库版本问题

同样错误的人可以修改一下
