Question

我一直在进行在线培训（https://www.udemy.com/building-an-e-commerce-store-using-java-spring-framework），当我完成applicationContext.xml时，我会收到以下错误。

ref="sessionFactory"表示以下内容：

Bean必须为org.hibernate.SessionFactory类型较少...（Ctrl + F1）检查Spring注入的值类型（属性和构造函数参数）

ref="dataSource"表示datasource unexpected。

我不明白我错过了什么。我该怎么纠正这个？

我已将我的项目上传到github：https://github.com/arendkolk/Wholesaleproducts

applicationContext.xml：

在pom.xml文件中，将所有依赖关系放在依赖关系标记内。然后它将完美构建。

    <dependency>
        <groupId>jstl</groupId>
        <artifactId>jstl</artifactId>
        <version>1.2</version>

Bean必须是＆＃39; org.hibernate.SessionFactory＆＃39;类型
