java - 将动态应用程序部署到 Eclipse 上的 Tomcat 服务器后，Spring Web REST API 的 HTTP 状态 404

Question

我从 https://start.spring.io/ 获得了一个新的 Spring Web 应用程序有一些依赖。每当我尝试访问 REST Controller 路径(“api/companies”)时，服务器都会发送带有以下消息的 404 结果:

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

这是我的 pom.xml:

项目结构如下:

应用程序的入口点是 CompaniesApplication 类:

package helium.erp.com.companies;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

@SpringBootApplication
public class CompaniesApplication extends SpringBootServletInitializer {

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

我尝试访问的 REST Controller 如下:

package helium.erp.com.companies.company;

import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/api/companies")
public class CompanyApi {
  @GetMapping(value = "")
  public ResponseEntity<String> getAllCompanies() {
    return ResponseEntity.ok("all companies");
  }
}

我在 WebContent 的根目录中放置了一个 html 文件，当我向“localhost:9091”发送 GET 时，它会完美返回。该项目被添加为服务器资源，以下是服务器的配置:

我已通过 Eclipse 项目设置 > Web 项目设置 > 上下文根将项目上下文根从默认的“公司”更改为“/”，并通过服务器模块设置更改了路径，如下所示:

我做错了什么？我是否缺少某些配置？

[已解决]修复 Eclipse 中的部署程序集路径解决了该问题。
