• Basic Knowledge of JAVA. Great tutorial on Javatpoint.
• Java JDK 8 at least installed locally Oracle Docs for Mac & Windows.
• Maven installed
• Basic knowledge of Springboot
• Postman
• Basics of Spring Annotations

Install all project dependencies with:

$ mvn install

Open a terminal and run the following commands to ensure that you have valid versions of Java and Maven installed:

$ java -version

$ mvn -v

You should get the versions of Java and Maven.

The Spring Boot Maven plugin includes a run goal that can be used to quickly compile and run your application. Applications run in an exploded form, as they do in your IDE. The following example shows a typical Maven command to run a Spring Boot application:

$ mvn spring-boot:run

####Using Executable Jar

To create an executable jar run:

$ mvn clean package

Step 19: Open the browser and invoke the URL http://localhost:8080/. It returns an empty list because we have not added any user in the List.

To add a user to the database, we will send a POST request by using the Postman.

Step 20: Open the Postman and do the following:

Select the POST

Invoke the URL http://localhost:8080/add-user.

Click on the Body

Select Content-Type as JSON(application/json).

Insert the data which want to insert in the database. We have inserted the following data:

{  
    "id": "001",  
    "name": "john",  
    "email": "[email protected]"  
}  

When we click on the Send button, it shows Status:200 OK. It means the request has been successfully executed.

Step 21: Open the browser and invoke the URL http://localhost:8080. It returns the user that we have inserted in the database.
