You can create a new Spring project using Spring Initializr. That is the name.<\/p>\n

First, not hat the spelling, ‘Initializr’ is not a typo.<\/p>\n

 <\/p>\n

So what is Spring Initializr?<\/strong><\/p>\n

Spring Initializr is an online tool you can use to generate Spring Starter project. Then you can download the project and open it in your local IDE.<\/p>\n

To use Spring Initializr, go to www.start.spring.io.<\/a> The page is as shown below:<\/p>\n

 <\/p>\n

\"\"<\/p>\n

 <\/p>\n

Leave the Generate a ‘Maven Project’ with ‘Java’.<\/p>\n

Also leave the Spring Boot version the default value. The value at the time of this tutorial is 2.1.3.<\/p>\n

 <\/p>\n

Under the group enter com.tutorials (you can change it)<\/p>\n

Under artifact, enter FirstApp (you can also change it)<\/p>\n

When you are done, click on Generate Project<\/p>\n

The zip file would be downloaded.<\/p>\n

Unzip the zip file into.<\/p>\n

Now you can open the sts IDE.<\/p>\n

Go to File and choose New > Open Project.<\/p>\n

Then navigate the to the folder that contains the downloaded project and select it<\/p>\n

 <\/p>\n

You can see that the project opens in sts. So in the Package Explorer, expand the project and open the pom.xml.<\/em> The content should look like shown below:<\/p>\n

 <\/p>\n

 <\/p>\n
Open the the FirstAppApplication.java File<\/strong><\/p>\n
Expand the src\/main\/java folder and locate the FirstAppApplication.java file (demoApplication.java)<\/p>\n
Open it<\/p>\n
Write this code inside the main method:<\/p>\n
 <\/p>\n
    System.<\/span>out<\/span>.<\/span>print<\/span>(<\/span>\"Welcome to Spring Initializr\"<\/span>);<\/span>\r\n<\/pre>\n
 <\/p>\n
The file should now look like this:<\/p>\n
\"\"<\/p>\n
 <\/p>\n
Click on Run in the menu.<\/p>\n
Select Run As > Spring Application as shown below<\/p>\n
 <\/p>\n
\"\"<\/p>\n
 <\/p>\n
The project would run, and you would have the output below. In the next tutorial, we would examine how to add REST endpoints.<\/p>\n
