commons-dbcp

commons-pool 

之后再Maven中加入了上述的两个依赖项

		<dependency>
			<groupId>commons-dbcp</groupId>
			<artifactId>commons-dbcp</artifactId>
			<version>20030825.184428</version>
		</dependency>
		<dependency>
			<groupId>commons-pool</groupId>
			<artifactId>commons-pool</artifactId>
			<version>20030825.183949</version>
		</dependency>

之后服务器正常启动
