创建名为'；数据源'；：调用init方法失败：javax.naming.NameNotFoundException:Name[jdbc/spring]

我正在尝试在SpringWeb应用程序中执行基本的MySQL数据库连接。所有配置都与我学习的教程一样，我得到以下控制台输出：

               url="jdbc:mysql://localhost:3306/"/>

</Context>

我正在使用Tomcat8.5.4和Java8。Spring jars版本是4.3.1，mysql connector java版本是6.0.3

在

context.xml

和

dao context.xml

中的jndi名称不应该映射到您的资源吗？资源名称是“jdbc/drewnostalDB”哇，真是个愚蠢的错误，谢谢你们的回答，它现在可以工作了；）

context.xml

和

dao context.xml

中的jndi名称不匹配，spring配置文件中的jndi名称“jdbc/spring”不应该映射到您的资源吗？资源名称是“jdbc/drewnostalDB”哇，真是个愚蠢的错误，谢谢你们的回答，它现在可以工作了；）
