最后它说:

Description:

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.

Reason: Failed to determine a suitable driver class


Action:

Consider the following:
    If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
    If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).
注意:有一件事我搞不清楚,我已经在pom.xml中注册了sql server驱动程序的依赖项,但该库在外部库中不存在

关于

试试这个:

1) 右键单击项目

2) Maven->更新项目

3) 再次刷新项目

或者尝试使用其他依赖项

<!-- https://mvnrepository.com/artifact/com.microsoft.sqlserver/sqljdbc4 -->
<dependency>
    <groupId>com.microsoft.sqlserver</groupId>
    <artifactId>sqljdbc4</artifactId>
    <version>4.0</version>
    <scope>test</scope>

测试

我已经搜索了这个版本,但在mvnrepository.com上找不到它。现在我复制了,它说找不到这个版本

您是否正确输入了此项???或者您可以尝试此项。问题与您提到的行无关。我已经读过那个教程了。如果您使用的是
mssql jdbc
依赖项,感谢您删除
JPA
依赖项。您试图将哪个数据库与此应用程序一起使用?这是个问题!Sql server
