Spring Boot Course

Learning Objectives:

In this Spring Boot training module, you will start with an introduction to embedded database and then understand where to use the embedded H2 database.

You will learn how to use H2 console UI. You will start by learning how to access the H2 console, followed by learning how to use it for executing queries.

Topics

• Embedded Database H2
• Configuring H2 Database
• How to Use H2 console UI

Learning Objectives:

You will understand what entity classes are and how they get mapped to database tables. You will learn about the difference between POJO and entity classes by designing the entity class bookstore. You will learn how to create an entity class with the JPA annotations at the rate Entity and at the rate ID and access the mapped table using the H2 console UI. Finally, you will learn how to use a true console UI to insert values in the derived table of the entity class.

Topics

• What are Entity Classes?
• Difference between POJO and Entity classes

Learning Objectives:

You will learn about JPA and Hibernate. You will look at what they are and their uses. You will learn how to create a Spring Boot repository using JPA. You will create a bookstore repository and then extend it with the JPA repository interface.

You will learn how to create a POST API called create bookstore. You will also create a GET API called get bookstores. You will then create a GET API called get bookstore by ID. You will create a GET API called get bookstore Which Has Particular Books. You will create a GET API called get Book Stores in Paged Format. You will create a GET API called countBookStores. Then, you will create a GET API called bookStoreExistById.

You will create a PUT API called update BookStoreName. You will then create a Delete API called deleteBookStoreById. Finally, you will create a Delete API called truncateBookStore in the BookstoreCRUDServiceIMPL class and test the method with the CommandLineRunner.

Topics

• JPA and Hibernate
• Creating a Spring Boot Repository
• Create a POST API ‘createBookStore()’
• Create a GET API ‘getBookStores()’
• Create a GET API ‘getBookStoreById()’
• Create a GET API for particular books
• Create a GET API getBookStoresInPagedFormat()
• Create a GET API countBookStores()
• Create a GET API bookStoreExistById()
• Create a PUT API updateBookStoreName()
• Create a DELETE API deleteBookStoreById()
• Create a DELETE API truncateBookStore()

Learning Objectives:

You will understand the difference between compile-time and runtime exceptions. You will implement runtime exceptions in the bookstore application.

Finally, you will implement compile-time exceptions in a bookstore application.

Topics

• Compile time and Runtime Exceptions
• Implement Runtime exception
• Compile-time exceptions in Library Applications

Learning Objectives:

You will learn about creating and implementing custom runtime exceptions. You will start with creating a custom runtime exception class BookStoreNotFoundRuntime ExceptionClass. Then, you are going to modify the updateBookstoreName method, and throw this new custom runtime exception.

You will learn to create and implement a custom compile-time exception. You will do this by creating a BookstoreNotFoundException class, modifying the updateBookStoreName method, and throwing the BookstoreNotFoundException.

Topics

• Creating and Implementing Custom Runtime Exception
• Creating and Implementing a Custom Compile Time Exception

Learning Objectives:

In this module of our Java Spring Boot course, you will learn what custom exception handler is in Spring Boot. You will learn to create responseErrorDto to class. You will create a response error DTO class with variables such as timestamp, and a list of error messages.

You will handle custom runtime exceptions. You will learn about @RestControllerAdvice and @ControllerAdvice annotations. You will learn how to create an exception handler method to handle the custom compile-time exception.

You will create an exception handler method to handle global runtime exception. You will create an exception handler method to handle global compile-time exceptions. Finally, you will learn to create and implement a custom compile-time exception.

Topics

• Custom Exception Handler
• Creating ResponseErrorDto Class
• Handling Custom Runtime Exceptions
• @RestControllerAdvice and @ControllerAdvice annotations
• Handling Custom Compile Time Exception
• Handling Global Runtime Exceptions
• Handling Global Compile Time Exceptions

Learning Objectives:

You will learn what configuration management is. You will learn the different tools we can use for configuration management. You will then explore the dependencies required for a Spring Boot Cloud Config Server project and look @enable Config Server annotation.

You will get a walk through the Spring Cloud Config Client 1 project. You will Learn how to point the Spring Cloud Config Server to a remote Git repository by first creating a remote Git repository and then pushing the changes from the local Git repository to the remote Git repository.

You will learn how to refresh imported properties. You will also learn how to manage configurations for multiple projects. Finally, you will create and implement a custom compile-time exception.

Topics

• Introduction to Configuration Management
• Tools for Configuration Management
• Spring Boot Cloud Config Server Project
• Spring Cloud Config Client 1 Project
• Pointing the Spring Cloud Config Server to Remote Git Repo
• Refresh Imported Properties
• Managing Configurations for Multiple Projects

Topics

• Inter-Process Communication
• Implementing Inter-Process Communication with OpenFeign

Learning Objectives:

In this module, you will learn how to create a security group in AWS. You will Understand what a security group is and then create one, which you can also use for any EC2 instance in the future.

While creating the security group, you will set some inbound and outbound rules. The inbound rules will allow the ipv4 and ipv6 source traffic and SSH TCP protocol port 22 sources. The outbound rules will allow all ipv4 destination traffic.

You’ll look at how to deploy an application to AWS EC2 service. You will follow the instructions written in the EC2 Deployment Guide provided and deploy the Spring Boot bookstore design application to an AWS EC2 Linux instance.

Topics

• Create a Security Group in AWS
• Deployment to AWS EC2 Service

Capstone Project:

As part of this Capstone project, you are going to design a Parking Lot Application, which can be used for keeping track of vehicles parked in the parking lot.
