I am trying to deploy the Spring Boot Application with WAR packaging to Tomcat 10. The application gets deployed successfully, however, when I try to access the endpoints it results in 404 Not Found.
WAR File: 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)
Tomcat webapps/application folder consists of following and index.html (Angular) have <base href="/">
As discussed here, I have added a class AppServletInitializer which extends SpringBootServletInitializer as follow
@Configuration
public class AppServletInitializer extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(SpringApp.class);
}
}
In pom.xml, I have added the dependency for spring-boot-starter-tomcat, tomcat-embed-jasper and set packaging option as war. I have shared the simplified (removed dependency, plugins. will add the same if required)

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

Answer
The configuration was correct in the Project. As mentioned in the comment, there might be some issue with Tomcat 10 as it was in the alpha version. I have used Tomcat 9 it was working fine.
The configuration are as below.
Step 1: Change the packing option to war in pom.xml
<packaging>war</packaging>
Step 2: extends 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);
}
}
Step 3: Create WAR file
mvn clean install
And there we go! We can access the endpoints at
http://localhost:8080/context-path/endpoint OR http://localhost:8080/war-filename/endpoint
We can also create the profile for war as below

<maven-war-plugin.version>3.2.3</maven-war-plugin.version>
