在测试springmvc的时候，出现Request processing failed; nested exception is org.springframework.transaction.CannotCreateTransactionException: Could not open JDBC Connection for transaction; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Access denied for user ‘root’@‘localhost’ (using password: YES))
问题描述`
Root Cause
org.springframework.transaction.CannotCreateTransactionException: Could not open JDBC Connection for transaction; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Access denied for user ‘root’@‘localhost’ (using password: YES))
原因分析：问题提示的很清楚，就是无法连接数据库，数据库拒绝访问。导致form表单页面出现不了，可以检查一下数据库的连接配置和数据库密码是否正确
解决方案：
修改数据库配置文件里的密码
