经过一些研究，我发现我的 class 注释可能有问题，但我检查了它们，它们看起来很好。知道如何解决这个问题以便我可以 运行 我的 jar 文件吗？
编辑
这里是classmk.klimasistemi.KlimasistemiApplication
package mk.klimasistemi;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
@SpringBootApplication
public class KlimasistemiApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(KlimasistemiApplication.class, args);
}
}
编辑 18.04.2022
我试图从 main 方法中删除 extends SpringBootServletInitializer 并从 pom.xml 中删除 tomcat 依赖项

按照以下两个步骤告诉我们。
第一步：
只需从主 class.
中删除 extends SpringBootServletInitializer
第 2 步：
从您的 pom.xml 文件中删除以下依赖项。
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
清理 maven，将新构建作为 jar 并 运行。
这里解决了我的问题。我不知道它的作用，也不知道它是如何工作的。但它有效。

经过一些研究，我发现我的 class 注释可能有问题，但我检查了它们，它们看起来很好。知道如何解决这个问题以便我可以 运行 我的 jar 文件吗？
编辑
这里是classmk.klimasistemi.KlimasistemiApplication
package mk.klimasistemi;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
@SpringBootApplication
public class KlimasistemiApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(KlimasistemiApplication.class, args);
}
}
编辑 18.04.2022
我试图从 main 方法中删除 extends SpringBootServletInitializer 并从 pom.xml 中删除 tomcat 依赖项
结果：

按照以下两个步骤告诉我们。
第一步： 只需从主 class.
中删除 extends SpringBootServletInitializer第 2 步： 从您的 pom.xml 文件中删除以下依赖项。
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
清理 maven，将新构建作为 jar 并 运行。
这里解决了我的问题。我不知道它的作用，也不知道它是如何工作的。但它有效。
