我有一个 spring boot rest web 应用程序，它可以在嵌入式服务器上完美运行。但是，按照博客中提到的步骤执行操作后 https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-create-a-deployable-war-file ，当我向服务器上的资源发送请求时收到 404 错误消息。我在本地使用了 java 1.8.0_212 并使用了 java 1.8.0_131 并将我的应用程序部署在服务器上的 tomcat 9 上。让我感到困惑的一件事是可以访问扩展 CrudRepository 的存储库。下面是我的应用程序的入口点。

@SpringBootApplication
@ComponentScan(basePackages = "com.dbe.ref")
public class RefmsApplication extends SpringBootServletInitializer {

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

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

还有我的 pom.xml

最佳答案

默认情况下，在嵌入式服务器和外部服务器上部署应用程序时会有一点不同。

使用嵌入式服务器，您可以使用以下方式访问您的应用程序:

http://localhost:<port>/<resourceName>

如果你在另一个容器中部署war，那么你需要添加带有版本的应用程序名称:

http://localhost:<port>/<applicationNameWithVersion>/<resourceName>

例如，如果您部署此 example那么嵌入式服务器的 URL 是:

http://localhost:8080/greeting

以及外部部署应用程序的 URL，如:

http://localhost:8999/gs-rest-service-0.1.0/greeting

注意:此 URL 是我的应用程序服务器的，因此它可能会针对您的进行一些更改。
