在类路径资源[spring / business-config.xml]中定义名称为'entityManagerFactory'的bean时出错

时间：2017-01-23 11:32:10

标签： java xml spring spring-mvc h2

我遇到了dataSource和entityManagerFactory之间的某些连接问题。未发送数据或未创建任何内容或bean。到目前为止我还没有使用过h2数据库引擎（创建一个内存数据库）所以现在我不知道应该在哪里查看或修改。欢迎任何建议。

此外，我到目前为止一直寻找解决方案，但没有人帮我解决这个问题。

该应用程序是来自YouTube的教程（我将提供源代码和视频的链接），我正在尝试将其集成到我的电脑上，但我遇到了困难。

视频教程的链接（第7部分是我关注的最后一部分）：https://www.youtube.com/playlist?list=PL4gCdGOq-cxJrbRMWjrIvGhYqQO1tvYyX

这是控制台输出错误：

您似乎缺少以下依赖

   
SELECT n.id, n.title, COUNT(*) as num_total,
       SUM(n.status = 'Not Completed') as num_not_completed,
FROM notes j JOIN
     dependency d
     ON d.task_dependency = n.id
WHERE e.task = '7035' 
GROUP BY n.id, n.title;

添加后再试一次。
