本文详细解析了在使用MyBatis框架时遇到的严重异常情况，包括数据库连接失败的具体原因及解决步骤，适用于SpringMVC整合MyBatis的项目。文章提供了检查数据库配置和确保虚拟机中数据库连接正常的解决方案。

严重: Servlet.service() for servlet [dispatcherServlet] in context with path [/heima_ssm_web1] threw exception [Request processing failed; nested exception is org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.exceptions.PersistenceException:
### Error querying database. Cause: org.springframework.jdbc.CannotGetJdbcConnectionException: Failed to obtain JDBC Connection; nested exception is java.sql.SQLException: Connections could not be acquired from the underlying database!
### The error may exist in com/itheima/ssm/dao/IProductDao.java (best guess)
### The error may involve com.itheima.ssm.dao.IProductDao.findAll
### The error occurred while executing a query
### Cause: org.springframework.jdbc.CannotGetJdbcConnectionException: Failed to obtain JDBC Connection; nested exception is java.sql.SQLException: Connections could not be acquired from the underlying database!] with root cause
com.mchange.v2.resourcepool.CannotAcquireResourceException: A ResourcePool could not acquire a resource from its primary factory or source.

问题解决

1.检查数据库配置；

2.如果你和我一样也是虚拟机中的数据库，检查虚拟机中数据库是否还能链接
