Java Spring Boot返回404

Question

当我从Eclipse运行Spring Boot应用程序时，它在嵌入式Tomcat服务器上正常运行，但当我将其部署到外部tomcat服务器（在Windows上）时，我将获得HTTP 404状态。

我清理了包并从本地tomcat服务器上tomcat webapps文件夹中的目标文件夹war文件中复制，然后重新启动了tomcat，但是。。。

当我运行获取方法在邮递员与endpointhttp://localhost:8080/export/test/我得到404未找到

Tomcat版本9
Java11

TOMCAT管理器：

@SpringBootApplication
public class ExportApplication extends SpringBootServletInitializer {

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

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(ExportApplication.class);
    }
}

应用特性：

server.servlet.context-path=/export

控制器：

package bojankosta.export.controller;

import bojankosta.export.service.ContinentService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class BasicController {

       @Autowired
       private ContinentService continentService;

       @GetMapping("/")
       public String getAllData()  {
              return continentService.export();
       }

       @GetMapping("/test")
       @ResponseBody
       public String currentUserName() {
              return "Hello";
       }

}

Answer 1

您可以在构建文件中使用finalName属性（maven的pom.xml）

<finalName>export</finalName>

Answer 2

404表示您正在点击的url不可用。当我们在外部应用服务器上部署代码时，它从根上下文（通常以项目名称开头）提供服务。您可以在日志中检查它所服务的是什么上下文，然后将其余endpoint附加到它。它会起作用的
