使用spring 生成dataSource时，遇到了问题。已经配置好了数据库"newsdb",现在要连接过去。 <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver"> </property> <property name="url" value="jdbc:mysql://127.0.0.1:3306/Mysql"> </property> <property name="username" value="root"> </property> <property name="password" value="123456"> </property> </bean> 正如上面的代码完成后，却提示： Creation of element failed. See error log for more details. 在error中找到了错误的说明： Internal Error java.lang.reflect.InvocationTargetException at org.eclipse.jface.operation.ModalContext.runInCurrentThread(ModalContext.java:477) at
