Google App Engine Spring Boot 出现 404 错误
[英]Google App Engine Spring Boot gives a 404 error
问题描述
将 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 package appengine:deploy -Dapp.deploy.projectId=pollog部署应用程序。
以下是应用部署后的日志：

应用程序.yaml：
runtime: java11
# entrypoint: java -Xmx64m -jar capripol-0.0.1-SNAPSHOT.jar
instance_class: F2
handlers:
- url: /.*
secure: always
redirect_http_response_code: 301
script: auto
- url: /login
secure: always
redirect_http_response_code: 301
script: auto
编辑：我尝试使用更大的实例类型 F4、F4_1G 但这没有区别。 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();
}

我也一直在尝试解决它，发现路径或路线是错误的。尝试找邮递员看看它是否有效。 pd：我发现我的参数也错了。 数据源用户名应该是在谷歌云上注册时创建的
