Properly setting up MS SQL Server with Spring Boot Application?

I'm having trouble setting up my MSSQL Database with my spring boot app. I'm new to spring boot, I'm not sure how to set up an entityManagerFactory, and my dependencies may be jumbled up. I tried reading the errors in the compiler but I'm still unsure. Somebody please help and let me know what I'm doing wrong. Thank you.
Application Properties
server.port=8080
spring.mvc.view.prefix=/pages/
spring.mvc.view.suffix=.jsp
spring.datasource.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.datasource.url=jdbc:sqlserver://localhost;databaseName=EXAMPLEDB
debug=true
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.format_sql = true
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.SQLServer2012Dialect
spring.jpa.hibernate.ddl-auto = update
My compiler

Based on the error message:

it appears that you are just failing to pass the 'spring.datasource.username' and 'spring.datasource.password' values in the application properties.

Springboot: org.hibernate.MappingException: Could not get constructor for org.hibernate.persister.entity.SingleTableEntityPersister

I know, it is duplicate question,but problem is new, Please do not mark duplicate question. This program runs in Window 10 it's run fine and create a database, but when same program runs in Debian 9 it throws exception. after that i checked this problem on google. some people said, create a all user class state setter and getter method. I created a setter and getter method but same exception is thrown.

The problem is with Jdk 11 and javassist.
Add this in your pom.xml:
<dependency>
<groupId>org.javassist</groupId>
<artifactId>javassist</artifactId>
<version>3.23.1-GA</version>
</dependency>
Info taken from: here
One needs to be careful when migration from Java 8 to Java 11, many things don't work out of the box.

You are defined the java.version = 1.8
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<java.version>1.8</java.version>
</properties>
This exception may cause if you use OpenJDK 11 (default on Travis-CI).
Try to change JDK version to 8 in .travis.yml like this:
jdk:
- openjdk8

Spring is not able to scan Product class.

"Error starting ApplicationContext" when executing spring application

I got few microservices and two are running great but on the other two I got some errors. The database schema is not created yet but usually it was created once I started the application successfully. I got similar running classes and I already tried few things such as deleting my repository in .m2 folder which didn't worked out.
I am also using eureka discovery service and eureka zuul.
I am not sure but I think it's not able to find the database schema. When I added a #Entity annotation in another but similar project it failed for the first time.
UPDATE
I figured out that I used the same coloumn name twice in a java class. So the first application is running again. But the second one (similar architecture) doesn't run when I am using annotations such as #Entity or #Column. When I delete them everything is working. The error message is the same.
UPDATE 2
I think it's a logical issue between the following two classes. I am two exhausted right now to figure out tho.

SOLVED THE ISSUE
The issue wasn't logical, at least not the way I expected it. I had no setter method for addressId!
Feeling so stupid right now.
My code wasn't able to set a primary key for AddressEntity

SpringBoot Controller error

I'm trying to create Spring Boot "Car rental" application, that will connect with database, so I can use simple operations like GET, POST, etc to test it. I've created 3 tables : Cars, Clients and Rentals (where rentals has foreign keys to client's and car's ids). But this is the error that I'm getting:
2017-06-13 22:22:59.238 ERROR 8044 --- [ main] o.s.b.d.LoggingFailureAnalysisReporter :
***************************
APPLICATION FAILED TO START
***************************
Description:
Parameter 0 of constructor in eu.fitk.controllers.CarsController required a bean named 'entityManagerFactory' that could not be found.
Action:
Consider defining a bean named 'entityManagerFactory' in your configuration.
and this is how my CarsController class looks like:
#RestController
#RequestMapping("/cars")
public class CarsController {
private final CarsRepository carsRepository;
public CarsController(CarsRepository carsRepository){
this.carsRepository = carsRepository;
}
#RequestMapping(method = RequestMethod.POST)
public void addCar(#RequestBody Cars car){
carsRepository.save(car);
}
#RequestMapping(method = RequestMethod.GET)
public List<Cars> getCars(){
return carsRepository.findAll();
}
}
I tried to add #Autowired annotation above CarsController constructor, but it didn't help, I'm new to Spring Boot and I don't really fully get how it is configurated.

dependencies is not needed, when i'm already using

already. Now i'm getting this kind of error:

Hibernate doesn't handle annotations added both on fields and on methods very well. Just move all the hibernate annotations either on fields either on methods in your entities.

Use Hibernate reverse engineering concept to generate Java persistent entities from database tables in eclipse
