Failed to obtain JDBC Connection; nested exception is java.sql.SQLException: Connections could not be acquired from the underlying database!
已经解决了，是数据库的url弄错了
数据库用的是MySQL，客户端用的是navicat，
它报出这个错误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!
我刚刚写完了
你用的什么数据库？ 客户端用的什么呢？
