Unable to reproduce problem.
This is not an answer, but I copied the 3 files from question, and built and ran code without problem. My console log is however a bit different, included below, and that's why I'm posting this as an answer.
Try doing a clean build. Maybe that will fix the problem.

Maybe your template doesn't exist. Please specify file name of template which map with the retured value. Check this example
#Controller
public class HelloWorldController {
#RequestMapping("/hello")
public String hello(Model model, #RequestParam(value="name", required=false, defaultValue="World") String name) {
String message="You just create Spring Boot Example successfully";
model.addAttribute("name", name);
model.addAttribute("message", message);
return "hello";
}
}
Found this from Spring Boot Maven Example Hello World

It's seems there is some problem at your port 8080.
please change port and try to restart your appliaction.
Example: Add below to your application.properties file
server.port = 8090
and then try hitting http://localhost:8090/hello

You can try this.
Using application.properties /yml
The most straightforward way of changing the context path is to set the property in the application.properties:
server.servlet.context-path=/demoApp
Instead of putting the properties file in src/main/resources, we can also keep it in the current working directory (outside of the classpath).
Java System Property.
http://localhost:8090/demoApp/hello
for more info.
https://www.baeldung.com/spring-boot-context-path

Do you create a jsp or html page called hi... Check your views... You don;t have page to view.... Please create a jsp and put it on
#RequestMapping("/hello")
public String sayHi(Model model) {
model.addAttribute("Hi","Hi")
return "Hi";
}
jsp page must be Hi

Apache Camel - Error in Code - PropertiesComponent with name properties must be defined in CamelContext to support property placeholders

I am creating simple Apache Camel Spring boot program to transfer a file from one directory to another.
I am using application.yml file for route properties.
I am getting below error -
Exception: java.lang.IllegalArgumentException: PropertiesComponent with name properties must be defined in CamelContext to support property placeholders. Property with key [startRoute] not found in properties from text: {{startRoute}}
If give route value hard coded in configure() it's working fine. But giving error on using application.xml

Wrong alignment in application.yml
If want to use property as {{startRoute}}, ensure no space before property in .yml file
or use absolute path like {{spring.startRoute}}
I have tested. Issue resolved.

Your controller is not scanned by the default component scan that Spring Boot provides. By default Spring boot starts from the package that contains the "main" class - the one annotated with #SpringBootApplication and also scans all of it's sub packages.
Your main class is in package com.template; but the controller is in package controller;. Move the controller in a package named package com.template.controller;

Since you are using FreeMarker Template with spring boot, I would suggest you to move your welcome.ftl template from this location src/webapp/welcome.ftl to this src/main/resources/templates/welcome.ftl and then restart your application and hit http://localhost:8080/welcome

Spring Boot Getting Startet 404 error

I'm trying to use the spring framework for the first time. Unfortunately I'm getting 404-error when I call the URL of my webservice. Tomcat deployment of the war file is working (no errors in the logs).
When I execute the Example.java in eclipse everythings works fine.
Where is the mistake?
See my files/logs:
Example.java
import org.springframework.boot.*;
import org.springframework.boot.autoconfigure.*;
import org.springframework.stereotype.*;
import org.springframework.web.bind.annotation.*;
#Controller
#EnableAutoConfiguration
public class Example {
#RequestMapping("/")
#ResponseBody
String home() {
return "Hello World!";
}

SpringApplication.run(Example.class, args);
}

Use #RestController instead of #Controller and just give request like
localhost:8080/

In order to deploy a spring-boot application to an external servlet container you need to extend SpringBootServletInitializer.
The main method is only executed when the application is run standalone.
It is recommended to run spring-boot apps standalone rather than via an external servlet container, but it is possible to support both methods simultaneously.
See the spring documentation for more information.

By Default context path of Spring boot application is '/'. So in your case url to access home resource will be http://localhost:8080/
For custom context path add an application.properties file to src\main\resources. In that properties file, add 2 properties:
server.contextPath=/Service
server.port=12378
You may refer this link for example.

Maybe url mistake. try it like the url below .
http://localhost:8080/Service/

You have not mapped your controller or method with any specific string.
#Controller
#EnableAutoConfiguration
public class Example {
#RequestMapping("/")
#ResponseBody
String home() {
return "Hello World!";
}
...
You have used #RequestMapping("/") which maps the home() method so you need to use localhost:8080/ url instead of localhost:8080/service
and if you want to use the service in url just change mapping to #RequestMapping("/service").

The easiest way out is just by replacing the annotation above the class respectively. And use the #RestController, then you move the #RequestMapping("/") above the class, Beneath the rest controller. Go to the Postman and call it with localhost:8080/ and that's all

First of all i don't understand why you use #ResponseBody a method which return type void. Remove it. Then you need to use View Resolver to show html page and if you want to redirect it you can use an approach like below:
#Controller
public class RestControllerClass {
#RequestMapping("/rest/test/")
public String testOne(HttpServletResponse response) throws IOException{
return "redirect:/help";
}
}
HelpController.java
#Controller
public class HelpController {
#RequestMapping("/help")
public String get(HttpServletResponse response) throws IOException{
return "help";
}
}
in application.properties under src/main/resources folder.
spring.mvc.view.prefix=/static/
spring.mvc.view.suffix=.html

When Is My Business Code Actually Being Executed?

I got a Spring Boot app. It's running as such:
#SpringBootApplication
public class MyBooty implements CommandLineRunner {
public static void main(String[] args) {
SpringApplication.run(MyBooty.class, args);
}
public void run(String... args) throws Exception {
SomeClass someClass = new SomeClass(...);
someClass.doStuff();
System.out.println("Why Am I appearing Before \"Started In\" log line?");
}
Does what I need. But I noticed this line in the output: Started MyBooty in 17.594 seconds (JVM running for 18.206), which was printed after some of my console output.
This made me think my code was actually executing before the app was actually initialized. So I did some research found this blog post and then set up a new class as such:
#Component
public class ApplicationStartup implements ApplicationListener<ApplicationReadyEvent>{
public void onApplicationEvent(ApplicationReadyEvent event) {
SomeClass someClass = new SomeClass(...);
SomeClass.doStuff();
return;
}
}
Which supposedly executes after after application startup. Well, I still see the Started app in... output after my output again.
So, concept check. Are things working as intended and I'm just being naive? Or is there maybe something missing? If someone could knowledge share on the topic that would be appreciated.
Again, my code runs and does exactly what I need it to, but I just want to make sure I'm using/taking advantage of Spring Boot properly.
In case it's unclear what I'm asking, I'm asking Why does the "Started App in X seconds" message appear after my output? I ask this because I simply found it confusing that it said the app was started after my business code had ALREADY ran. This question is a conceptual question about how spring boot starts up.

You class is annotated with #SpringBootApplication, which makes it automatically register as a Spring Bean.
The SpringApplication run(Object source, String... args) method you are calling ends up calling run(String... args).
The run() method calls the afterRefresh() method right before it logs the "Started ..." message, and afterRefresh() will call the run() method of any registered ApplicationRunner and CommandLineRunner beans.
Or, as the documentation says it:
If you need to run some specific code once the SpringApplication has started, you can implement the ApplicationRunner or CommandLineRunner interfaces. Both interfaces work in the same way and offer a single run method which will be called just before SpringApplication.run(…) completes.

It's seems there is some problem at your port 8080. please change port and try to restart your appliaction. Example: Add below to your application.properties file server.port = 8090 and then try hitting http://localhost:8090/hello

Do you create a jsp or html page called hi... Check your views... You don;t have page to view.... Please create a jsp and put it on #RequestMapping("/hello") public String sayHi(Model model) { model.addAttribute("Hi","Hi") return "Hi"; } jsp page must be Hi
