I deployed my spring boot project with jar file on my server and can't access it

I deployed my spring boot project with jar file on my lightsail server. I think it deployed fine however, I can't access it.
Chrome says,

I remove server.address=localhost from application.properties and it works well.

Injecting JdbcOperationsSessionRepository into a constructor

I'm upgrading a SpringBoot app from 2.1.17 to 2.3.4, which includes this class:
#Configuration
public class SessionRepositoryConfig {
public SessionRepositoryConfig(JdbcOperationsSessionRepository sessionRepo) {
// configure session expiry + table name + converter
...
...
}
}
This is the only mention of JdbcOperationsSessionRepository in the entire code-base, so presumably in 2.1.17 a bean of this type was automatically made available by SpringBoot. However, when I switch to 2.3.4 the injection fails:

Fixed by replacing JdbcOperationsSessionRepository with JdbcIndexedSessionRepository

There was an unexpected error (type=Not Found, status=404). - Spring Java

I have this service in github https://github.com/felloz/personsService The application compile with no errors but when im trying to access the route http://localhost:8080/demo/persons Im getting this error:
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

you have #RequestMapping({"/persons"}) in your controller, so try this link http://localhost:8080/persons without demo

after spring 2 , context path configuration has been changed ;
server.servlet.context-path=/demo
And then try http://localhost:8080/demo/persons

If you don't want to use Jpa, following changes would be needed :
Context Path should be set as:
server.servlet.context-path=/demo
DemoApplication Class (correcting base package):
#SpringBootApplication
#ComponentScan(basePackages = {"com.example"})
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
You need to provide the implementation for your Repositoory:
import java.util.ArrayList;
import java.util.List;
import org.springframework.stereotype.Repository;
#Repository
public class PersonRepository{
public List<Person> findAll(){
List<Person> list = new ArrayList<>();
Person person = new Person();
person.setId(10001);
person.setName("Name");
person.setLastname("LastName");
list.add(person);
return list;
}
}
To work with MySQL DB and SpringBoot , you can find many example on web. Please follow that. Example : SpringBootMySQLExample

Java: Eclipse console doesn't display Spring Controller information

When I run my spring boot application in eclipse 4.7.3 IDE, the console doesn't display the information about the rest controller. Nevertheless the controller is working when I test it with browser.
It is just a "Hello World" application:
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class HelloWorldSpringBootApp {
public static void main(String[] args) {
SpringApplication.run(HelloWorldSpringBootApp.class, args);
}
}
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
#RestController
public class HelloWorldController {
#RequestMapping(value = "/")
public String helo() {
return "Hello World!";
}
}

As above it just display until "Started HelloWorldSpringBootApp in 1.904 seconds" without the request mapping status & mapped URL path info. Why?

The log output was changed in Spring 2.1. That changelog states that
If you are trying to debug an application and you want to restore
Spring Boot 2.0 style logging you should add the following to your
application.properties
logging.level.web=debug
This change however does not output what I would expect given this RestController
#RestController
public class HelloWorldController {
#RequestMapping(value = "/hello")
public String hello() {
return "Hello World!";
}
}
If I set the log level to trace it gives the expected output (though not in the exact same way as Spring Boot 2.1).
10:53:26.427 [main] TRACE o.s.w.s.m.m.a.RequestMappingHandlerMapping -
c.i.e.d.r.HelloWorldController:
{ /hello}: hello()
The requirement for trace log level is most likely due to a change in Spring Framework 5.1 (see release note)

When I tried to access the application through url 'http://localhost:8080/process', It says Site can't be reached.

Why would you do such thing? This should be a unit test and the flow of the test should be the following:
Start the application -> Call your controller endpoint -> assert that a specific text/element on that page is present -> Shut down the application.
Start the application : #RunWith(SpringRunner.class) doing this for you, no need to start is manually.
Shut down the application : At the end of your test class Spring boot does this for you (That's why you cant access your app in the browser)
For further help please see my answer here: How to test (rest) enpoints

By default, in #SpringBootTest annotation the field webEnvironment is set to WebEnvironment.MOCK
Therefore, Tomcat does not start.
You can set this field to WebEnvironment.DEFINED_PORT/RANDOM_PORT.
After this, Tomcat will be running.
#SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)
public class MyTestClass {
