i read my console and found that the main reason behind this failure was ambiquity in #RequestMapping in my Home.controller so i updated my annotation and then my Homepage start loading just fine

I am trying to run a Vaadin projekt with Spring Boot on a Tomcat applicationserver on a Ubuntu 18.04 Server.
I downloaded the Vaadin Flow Spring Starter Projekt: https://vaadin.com/start/latest/project-base-spring
But when I deploy it on tomcat and try to open it, I get this error:
There was an exception while trying to navigate to '' with the exception message 'Unable to create an instance of 'de.web.michail.spring.MainView'. Make sure the class has a public no-arg constructor.'
java.lang.IllegalArgumentException: Unable to create an instance of 'de.web.michail.spring.MainView'. Make sure the class has a public no-arg constructor.

I don't understand how this base example project is not running.
Do you thing tomcat is the issue? Maybe an other applicationserver like WildFly will run correct?
Let Application extend SpringBootServletInitializer solves the issue.
public class Application extends SpringBootServletInitializer {
// ...
}
The project that I have is currently set up like so:
Controller:
package com.frclocks.district.controller;
:imports:
#Path("/districts")
#Controller
public class DistrictController {
#Autowired
private DistrictService districtService;
#GET
#Produces(MediaType.APPLICATION_JSON)
public List<District> getDistricts() {
return districtService.getAllDistricts();
}
}
Service (Impl):
package com.frclocks.district.service;
:imports:
#Service("districtService")
#Transactional
public class DistrictServiceImpl implements DistrictService {
#Autowired
private DistrictDao districtDao;
#Override
public List<District> getAllDistricts() {
return districtDao.getAllDistricts();
}
}
Config:
package com.frclocks.config;
:imports:
#Configuration
#ComponentScan(basePackages="com.frclocks", includeFilters=#ComponentScan.Filter(Controller.class))
public class AppConfig { }
The web.xml is empty as I'll be using JavaConfig instead of xml, nor do I have any spring config xml. I have read through several tutorials online, several threads on here, and even browsed through a project at work that I'm developing with which also uses #Autowired and have reached a brick wall. Some of the tutorials say to do something in a main class (such as here: Spring Docs) but the project at work doesn't do anything like that. It has a similar AppConfig (with a few additional, not necessary annotations for me) and no xml config files. What would I be doing wrong? What am I missing here? Thanks!

You have mixed RestEasy and Spring MVC. You should decide for either of those frameworks for your REST endpoints. #Controller is a Spring annotation, while #Path is a JAX-RS annotation. Both together don't work. Currently your Controller is called through RestEasy, which doesn't know anything about your Spring configuration.
I have a 1000s of IOT devices continuously sending data in form of small files (1 Kb approx) to my Spring-Boot Application server.
I keep getting this error at specific intervals. Could someone point out what is wrong?
I have Controllers to upload files as well as a TCP socket.

A firewall may drop a TCP connection that has been inactive for a longer period. A solution is to send TCP keepalives.
Check also that both the maximum amount of connection through the firewall, and that the maximum number of OS file descriptors is not exceeded.
My Spring Boot REST application only uses Thymeleaf for mail templates.
Unfortunately my boot configuration tries to resolve an error template when an error is encountered.

This seems to indicate that Spring Boot has configured a Thymeleaf view resolver for pages (whereas I only uses Thymeleaf for mail templates).
How can I make sure Spring Boot only uses Thymeleaf for mail templates and thus avoid the above exception?
edit: I have the following line to my application.properties
server.error.whitelabel.enabled=false
but it does not seem to make any difference.
Using this property in application.properties:
spring.thymeleaf.enabled=false
seems to disable thymeleaf for spring mvc - whilst still keeping thymeleaf for mail templates.
see spring boot source code here.
edit:
Furthermore, it seems necessary to disable the default error controller registered by Spring Boot: see here.
One can for instance implement a custom error controller as described here: https://stackoverflow.com/a/25362790/536299
#SpringBootApplication(
exclude = {
ThymeleafAutoConfiguration.class,
})
public class ApiApplication {
public static void main(String[] args) {
SpringApplication.run(ApiApplication.class, args);
}
}
I have a simple Wicket 7.4.0 project when Wicket is configured inside of SpringBoot. I have #Service spring beans that want to inject into Wicket pages. Now when Wicket page is mounted by mountPage(..) command #Inject annotation works fine for wicket page. But #Inject doesnt work for wicket pages mounted by AnnotatedMountScanner() . Any idea whats wrong here? See my code snippet below.
#Override
public void init() {
super.init();
getComponentInstantiationListeners().add(
new SpringComponentInjector(this, applicationContext));
new AnnotatedMountScanner().scanPackage("com").mount(this);
mountPage("/x", PageAbout.class);
getMarkupSettings().setDefaultMarkupEncoding("utf-8");
}
EDIT #1 - Full traceback I'm getting
Unexpected RuntimeException
Last cause: Concrete bean could not be received from the application context for class: com.dubture.TestService.
