谷歌应用引擎Spring Boot给出一个404错误

蒋文光
2023-03-14

将我的Spring Boot应用程序部署到Google App Engine时，我在尝试访问Web应用程序时收到404错误。该应用程序在本地运行良好，但拒绝在应用程序引擎上运行。我使用命令mvn包appEngine：部署-Dapp.deploy.projectId=pollog部署应用程序。

以下是部署应用程序后的日志：

  redirect_http_response_code: 301
  script: auto
- url: /login
  secure: always
  redirect_http_response_code: 301
  script: auto

编辑：我尝试使用更大的instace类型F4，F4_1G但这没有任何区别。我还添加了以下内容来抑制有关端口的警告，但这没有任何区别：

public static void main(String[] args) throws IOException {
        SpringApplication.run(CapripolApplication.class, args);
        int port = Integer.parseInt(System.getenv().getOrDefault("PORT", "8080"));
        HttpServer server = HttpServer.create(new InetSocketAddress(port), 0);

        // Set root URI path.
        server.createContext("/", (t) -> {
        byte[] response = "Hello World!".getBytes();
        t.sendResponseHeaders(200, response.length);
        try (OutputStream os = t.getResponseBody()) {
            os.write(response);
        }
        });

        // Create a second URI path.
        server.createContext("/foo", (t) -> {
        byte[] response = "Foo!".getBytes();
        t.sendResponseHeaders(200, response.length);
        try (OutputStream os = t.getResponseBody()) {
            os.write(response);
        }
        });

        server.start();
    }
