解决Connections could not be acquired from the underlying database!

之前一直认为是代码错了,后来网上查资料,发现可能是C3P0和mysql的版本不匹配导致的,更改完C3P0的版本 以后就好了,更改完的版本如下:
<dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.48</version> </dependency> <dependency> <groupId>c3p0</groupId> <artifactId>c3p0</artifactId> <version>0.9.1.2</version> </dependency>
