spring-boot-rest-api-tutorial | Sample REST CRUD API with Spring Boot, Mysql, JPA and Hibernate | Object-Relational Mapping library

I'm new to programming and I got a project to make a rest API. I made one using spring boot to use GET and POST operations. Now I'm trying to get it to work on a simple java application where,

• The user inserts their first name using the java scanner.
• Then sends a POST request to send it to a database.

So far the API works fine in Postman but I have no idea on how to add it to java using a method.

( I used this tutorial to make the api : https://www.callicoder.com/spring-boot-rest-api-tutorial-with-mysql-jpa-hibernate/ )

I have created a docker container of mysql with the database init. Now i am trying to connect my local spring boot project with that mysql in container. It always give me communication link failure.

application.properties

Edited to add proc structure:

main/java hello(package) Application(main app) TestRestController models(package) Test services(package) TestRepo(interface)

I'm currently looking at component scan as just released the 'repo.Test' in the exception is a clue.

I've been through numerous tutorials and questions and still cannot find the answer to my particular issue, which is most likely to be down to my lack of understanding.

I have a spring boot application that I'm adding a db to. I've been following this tutorial : https://www.callicoder.com/spring-boot-rest-api-tutorial-with-mysql-jpa-hibernate/

However when I try and run my application (following identical steps) I get an exception:

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'testRestController': Unsatisfied dependency expressed through field 'testRepo'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'repo.TestRepo' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

I do have another bean autowired in, the main difference is that this bean(the one that works) has a service that implements the interface and a bean configuration class. None of the examples for JPA follow that model and it seems daft to create a service to re-implement the methods from the JPARepo.

This is the controller I'm using:

I am trying to create webservices in JAVA Spring boot with backend as SQL Server 2012. I followed the tutorial from this website https://www.callicoder.com/spring-boot-rest-api-tutorial-with-mysql-jpa-hibernate/.

The only change i did was, changed the application.properties as

I am working on Spring Boot MySQL example following link : https://www.callicoder.com/spring-boot-rest-api-tutorial-with-mysql-jpa-hibernate/. I am getting below url when trying to access
