Question

I have a springboot application and i configured it to package as a war below are the changes i did.

pom.xml

...
<packaging>war</packaging>
...
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <scope>provided</scope>
</dependency>

Main application

public class TestApplication extends SpringBootServletInitializer {
    public static void main(String[] args) {
      SpringApplication.run(TestApplication.class, args);
    }
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(TestApplication.class);
    }
}

and then build the war file using maven plugin. then copied the war file to a running tomcat instance in webapps folder it extracted the war file and published the application.
i am able to access all API and static routes but the routes which return templates are giving the below error

I even checked that the templates folder is being extracted into /WEB-INF/classes/.
Also before the application is running perfectly fine using standalone tomcat server.

I am using Tomcat server v9 (External), springboot 2.7.8, spring-boot starter thymeleaf.

Please help me resolve the issue, any help is appreciated.
