我正在尝试在tomcat服务器上运行springboot应用程序，但是我的所有实验都失败了。
在这里你可以看到 pom.xml :

    </build>

</project>

主要类别：

package com.example.SpringbootTomcat;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
@RestController
public class SpringbootTomcatApplication {

//  @GetMapping("/test")
    @RequestMapping(value = "/test")
    public String test(){
        return "Application deployed!";
    }

    public static void main(String[] args) {
        SpringApplication.run(SpringbootTomcatApplication.class, args);
    }

}

servletinitializer位于另一个类中：

package com.example.SpringbootTomcat;

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

public class ServletInitializer extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(SpringbootTomcatApplication.class);
    }

}

它是以这种方式从https://start.spring.io/.
tomcat正在本地主机1234上运行。
我把war文件复制到了 webapps 文件夹。但是，当我在浏览器中键入 http://localhost:1234/SpringbootTomcat-0.0.1-SNAPSHOT/test ，我得到以下信息：

HTTP Status 404 – Not Found
Type Status Report

Message The requested resource [/SpringbootTomcat-0.0.1-SNAPSHOT/test] is not available

Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

我正在计算机上运行tomcat 10.0.6， CATALINA_HOME 设置为tomcat的文件夹， CLASSPATH 是 CATALINA_HOME\lib .
它只能作为maven应用程序使用，不能作为tomcat应用程序使用。
那么如何在tomcat服务器上运行应用程序呢？
