解决方法：
缺少commons-dbcp.jar、commons-pool.jar这两个包
在pom.xml中加入：
1 <dependency> 2 <groupId>commons-dbcp</groupId> 3 <artifactId>commons-dbcp</artifactId> 4 <version>1.4</version> 5 </dependency> 6 7 <dependency> 8 <groupId>commons-pool</groupId> 9 <artifactId>commons-pool</artifactId> 10 <version>1.6</version> 11 </dependency>
