Wdróż WAR na Tomcat (Spring Boot + Angular)

Próbuję wdrożyć aplikację Spring Boot z pakietem WAR na platformę Tomcat 10. Aplikacja zostaje pomyślnie wdrożona, jednak gdy próbuję uzyskać dostęp do punktów końcowych, pojawia się błąd 404 Not Found .

Plik WAR: application.war

http://localhost:8080/application/api/abc -> 404 Not Found (Spring Boot Endpoint)
http://localhost:8080/application/abc -> 404 Not Found (Angular URL which calls /api/abc)

webapps/applicationFolder Tomcat składa się z następujących i index.html(Angular) mieć<base href="/">

Jak omówiono tutaj , dodałem klasę, AppServletInitializerktóra rozszerza się SpringBootServletInitializerw następujący sposób

@Configuration
public class AppServletInitializer extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(AutomationwhizApp.class);
    }
} 

W pom.xml dodałem zależność dla spring-boot-starter-tomcat, tomcat-embed-jasper i ustawiłem opcję pakowania jako war . Udostępniłem uproszczoną (usunięta zależność, wtyczki. Dodam to samo, jeśli to konieczne)

Używamy Angulara po stronie klienta, a zasoby znajdują się w folderze statycznym.

Środowisko: Spring Boot 2.1.8, Angular 8, Java 11,

Wspomniałem już, niestety, żaden z nich nie pracuje dla mnie. Każda pomoc byłaby doceniona

1. Utwórz wdrażalny plik wojenny
2. Wdrożenie Spring Boot War
3. Nie można uzyskać dostępu do wdrożonego pliku WAR na serwerze Tomcat

Konfiguracja w projekcie była poprawna. Jak wspomniano w komentarzu, może wystąpić problem z Tomcat 10, ponieważ był w wersji alfa. Użyłem Tomcat 9, działało dobrze.

Konfiguracja jest jak poniżej.

Krok 1: Zmień opcję pakowania na wojnę w pom.xml

<packaging>war</packaging>

Krok 2: rozszerza SpringBootServletInitializer

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

/**
 * This is a helper Java class that provides an alternative to creating a {@code web.xml}.
 * This will be invoked only when the application is deployed to a Servlet container like Tomcat, JBoss etc.
 */
public class ApplicationWebXml extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {       
        return application.sources(ApplicationApp.class);
    }
}

Krok 3: Utwórzplik WAR

mvn clean install 

I gotowe! Możemy uzyskać dostęp do punktów końcowych pod adresem

http://localhost:8080/context-path/endpoint OR
http://localhost:8080/war-filename/endpoint

Możemy również utworzyć profil warjak poniżej
