推荐答案

请确保打开pom.xml而非文件夹. IntelliJ将询问您是否要导入为项目.对这个问题回答是. 您始终可以右键单击pom.xml，然后选择Maven-> Reimport，它将自动为您创建类路径.

Be sure to open the pom.xml and not the folder. IntelliJ will ask if you want to import as a project. Answer yes to this question. You can always right-click on the pom.xml and choose Maven->Reimport which will do the classpath for you automatically.

然后从树中转到主类，然后右键单击并选择运行".那应该在您的运行配置中创建一个临时配置.

Then you go to the main class from the tree and right-click and choose Run. That should create a temporary configuration in your run configurations.

如果要作为Maven项目运行，请执行以下操作:

If you want to run as a maven project, go with this:

如果要以Java jar从终端运行，则在构建spring-boot-jar时，按CTRL + TAB + T(以激活终端)并输入终端: java -jar target/yourjar.jar

If you want to run from terminal as java jar, when you have built your spring-boot-jar press CTRL+TAB+T (to activate terminal) and type in the terminal: java -jar target/yourjar.jar
