Cannot determine embedded database driver class for database type NONE while running jar
提问by Anas
As mentioned in the headline of question I am facing issue Cannot determine embedded database driver class for database type NONE. The application I have built is on spring boot and working fine when I run the code in intellij.
正如问题标题中提到的，我面临问题Cannot determine embedded database driver class for database type NONE。我构建的应用程序在 spring boot 上运行，当我在 intellij 中运行代码时工作正常。
I have followed several questions regarding the same exception and they suggested that I need to add spring.datasourceproperties in my application.properties file. I already have them and still facing the same issue. This issue occurs when I create jar file using artifacts of intellij and then run it by the following command.
java - jar myJar.jar
我已经关注了关于相同异常的几个问题，他们建议我需要spring.datasource在我的 application.properties 文件中添加属性。我已经有了它们，但仍然面临同样的问题。当我使用 Intellij 的工件创建 jar 文件，然后通过以下命令运行它时，会发生此问题。
java - jar myJar.jar
My application.properties file
我的 application.properties 文件
# ===============================
# = DATA SOURCE
# ===============================
spring.datasource.url = jdbc:mysql://localhost:3306/db_wssmith?useSSL=false
spring.datasource.username =
spring.datasource.password =
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (no profiles are currently active).

You should create the jar from maven, to do that go to Viewon top then Tool Windows/Maven Projectsand from there double click on install in LifeCycleoption in maven. Use the jar created by that command instead of using intellij. It Should work.
您应该从 maven 创建 jar，为此转到顶部的查看，然后是工具 Windows/Maven 项目，然后双击maven中的生命周期选项中的安装。使用该命令创建的 jar 而不是使用 intellij。它应该工作。
