[英]google cloud app engine and spring boot bug on localhost deploy with app engine
[英]Google cloud App engine Spring deploy error
Im trying to deploy a springboot rest api to google cloud's app engine, following this recent tutorial: https://medium.com/@smccartney09/deploy-a-spring-boot-api-to-gcp-app-engine-722198bab4d4and
但是我收到了這個錯誤:
org.springframework.context.ApplicationContextException: Unable to start ServletWebServerApplicationContext due to missing ServletWebServerFactory bean.
該應用程序在本地主機中正常運行,從我所看到的嘗試調試來看,在本地主機上 springboot 啟動了 tomcat web 服務器,並且它不在谷歌應用程序運行部署的日志中。 這是否意味着我必須使用谷歌的 web 服務器而不是 tomcat? 我真的很迷茫,因為我現在做錯了什么。

主要的:
@SpringBootApplication
@EnableCaching
public class OwlServerApplication {
public static void main(String[] args) {
SpringApplication.run(OwlServerApplication.class, args);
}
好的,所以經過大量閱讀后,我認為這可能是因為谷歌應用引擎不支持 tomcat 作為網絡服務器,而只支持碼頭? 所以我嘗試了以下方法:
添加到 pom xml:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<scope>provided</scope>
</dependency>
</dependencies>
但這什么也沒做,同樣的錯誤。 然后我也嘗試添加碼頭,它在本地運行得很好,作為碼頭 web 服務器,但在應用程序引擎上給出了相同的錯誤。 所以我們知道錯誤是由於谷歌應用引擎不支持 tomcat 或碼頭,但我現在用什么? 有人知道出了什么問題嗎?
所以經過大量調試,這里的問題出在spring安全性上。 If you have a class that extends WebSecurityConfigurerAdapter, spring will automatically attempt to use apply it to the embedded tomcat web server. 谷歌應用引擎不支持它,這打破了它。 只需刪除 class 即可運行該應用程序。
