I have a problem since I export and import a spring project, and it is that now it takes more than 70 seconds to start. Get stuck in Triggering deferred initialization of Spring Data repositories ...

In case it works for someone, I found the solution. I just had to add these two lines in my properties file and I went from starting in 70 seconds to starting in 4 seconds
spring.jpa.properties.hibernate.temp.use_jdbc_metadata_defaults=false
spring.jpa.properties.hibernate.dialect =org.hibernate.dialect.Oracle12cDialect

Sping Boot Java backend application process gets killed

I have packaged my spring boot rest backend with mvn package.
When I run the jar on the server with java -jar ... the application starts and gets killed after a few seconds.
I also see that on the linux top view, that the java process goes over 300% CPU. Is that maybe the reason the process gets killed? And if yes, what can I do?
My spring boot application is not very big. Actually its almost empty.

Some ideas to check:
Try to run as detached: java -jar yourapp.jar &
Try ( just once ) to run under root
Check logs: journalctl -ex for details of who exactly has killed your application.
Depends on results, can plan next steps - typically which settings to adjust.

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

I have tested. Issue resolved.

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.

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

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.
