spring boot execution: org.apache.tomcat.util.scan.StandardJ

我是 spring boot 的新手，并尝试在 spring boot 中从一个简单的项目开始，但无法将项目作为 Java 应用程序启动并收到下面提到的错误消息，

项目结构

SpringBootWebApplication.java

package main.java.com.test;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
@SpringBootApplication
public class SpringBootWebApplication extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(SpringBootWebApplication.class);
}
public static void main(String[] args) throws Exception {
SpringApplication.run(SpringBootWebApplication.class, args);
}
}

欢迎控制器.java

package main.java.com.test;
import java.util.Map;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class WelcomeController {
// inject via application.properties
@Value("${welcome.message:test}")
private String message = "Hello World";
@RequestMapping("/")
public String welcome(Map<String, Object> model) {
model.put("message", this.message);
return "welcome";
}
}

欢迎.jsp

以下是我在/WEB-INF/lib 下添加的 Jar 列表

我在这里做错了什么以及如何解决此错误？我已经尝试了先前查询中可用的答案，但无法解决此问题。

转到项目属性 ->项目方面 -->从运行时取消选中 tomcat。

我发现问题是由我为该项目配置的 tomcat 服务器引起的，我从项目中删除了服务器，现在能够将该项目作为 java 应用程序运行而没有任何问题。
