it helps some times You found the right question but it doesn't seems you added the solution in the answer, you need to Add an InternalResourceViewResolver
@Bean
public ViewResolver getViewResolver(){
    InternalResourceViewResolver resolver = new InternalResourceViewResolver();
    resolver.setPrefix("/WEB-INF/jsp/");
    resolver.setSuffix(".jsp");
    resolver.setViewClass(JstlView.class);
    return resolver;
}

So waht I don't understand how Tomcat can't find primitive datatypes like boolean and why it does work when i run it locally.
@Bean
public JobApplicationDTO getJobapplicationDTO (boolean resume, ...)

Updating from springboot 2.0.2 to springboot 2.1.2 results in No qualifying bean of type exception

To fix the issue you can do An interesting arrangement here that works but it could very well not depending on how the ApplicationContext processes the bean definitions.
On one hand a TaskExecutor is exposed and on the other you are requesting that very specific bean with a different type. The context may not be able to honour that and if that's what you want, you must narrow down the return type of the bean definition to ThreadPoolTaskExecutor.
@EnableScheduling
@EnableAsync
@Configuration
public class MyConfiguration {}

SpringBoot JPA @Autowired no bean found exception

I hope this helps . You are getting this exception because your class TestRepo is part of repo package, which is not the sub-package hierarchy of Application class package. @SpringBootApplication defines an automatic component scan on the packages which are subpackages of your main class i.e Application. If you want to resolve this issue without changing your package hierarchy add below line with @SpringBootApplication:
@ComponentScan({"repo","your.application.class.package"}) //// add the names of the packages where the controllers, services, repositories beans are stored

No unique bean of type is defined: expected single matching bean but found 2
