解决方案
解决方案二：
<propertyname="datesource"ref="datesource"></property>后面的ref对应的值可以随便取，但是前面的property的name值可不能随便取，是dataSource
解决方案三：
<propertyname="datesource"ref="datesource"></property>，哈哈，name="datesource"意味着为变量名为dateSource的变量赋值的，不能随便写的...可以用代码助手自动生成啊
解决方案四：
Spring异常提示已经很明白了呀,DataSource这里的问题呀!beanproperty'datasource'isnotwritable
