School project to customize a Spring Framework application with an HTML front-end and a Java backend for a retailer's inventory management system.

Step 1)

src/main/resources/templates/mainscreen.html, line 14, changes title to "My Soccer Shop";
-mainscreen.html, line 19, changes header to "Soccer Shop";
-mainscreen.html, line 21-22, adds static lists of parts and products;

Step 2)

new file: src/main/resources/templates/about.html;
-mainscreen.html, line 91, adds link to "About Us" page;
-about.html, line 5, adds "About Us" title
-about.html, line 8, adds "About Us" header
-about.html, line 9, adds description of business
-about.html, line 10, adds linebreak
-about.html, line 11, adds return link to mainscreen;
new file: src/main/java/com/example/demo/controllers/AboutController.java;
-AboutController.java, line 6-11, creates new class AboutController for page links;

Step 3)

com/example/demo/bootstrap/BootStrapData.java, lines 42-96, creates 5 new parts;
-BootStrapData.java, lines 79, creates 'inventoryCheck' boolean set to false;
-BootStrapData.java, lines 80-82, iterates through parts repository; changes inventoryCheck to true if any are found;
-BootStrapData.java, lines 108-110, iterates through products repository; changes inventoryCheck to true if any are found;
-BootStrapData.java, lines 119-130, if inventoryCheck is false, products & parts are added to repositories.  

Step 4)

new file: src/main/resources/templates/buy-now.html;
-controllers/AddProductController.java, line 171-191, creates new controller and method for buy-now . Checks product inventory and if zero, creates failure message.  If >0, creates success message and reduces item inventory by 1.
-buy-now.html, line 9, creates display for success/failure message from controller;
-mainscreen.html, line 86, adds button for 'buy now' to product table;

Step 5)

com/example/demo/domain/Part.java, lines 31-34, creates minInv and maxInv class variables for Part; -Part.java, lines 49-50, adds minInv and maxInv to constructor; -Part.java, lines 59-59, adds minInv and maxInv to constructor; -Part.java, lines 94-103, creates setter and getter methods for minInv and maxInv; -mainscreen.html, lines 38-39, adds table columns for min/max attributes; -mainscreen.html, lines 48-49, adds min/max attributes to table;

-BootStrapData.java, lines 49-50, add minimum and maximum to sample inventory part o1; -BootStrapData.java, lines 58-59, add minimum and maximum to sample inventory part o2; -BootStrapData.java, lines 67-68, add minimum and maximum to sample inventory part o3; -BootStrapData.java, lines 76-77, add minimum and maximum to sample inventory part o4; -BootStrapData.java, lines 85-86, add minimum and maximum to sample inventory part o5; -templates/InhousePartForm.html, lines 25-28, add form fields for minInv and maxInv; -templates/OutsourcedPartForm.html, lines 25-28, add form fields for minInv and maxInv;

src/main/resources/application.properties, line 6, renamed storage file as: "spring-boot-h2-db102-RENAMED"

new file: src/main/java/com/example/demo/validators/InventoryMinMaxValidator.java new file: src/main/java/com/example/demo/validators/ValidPartsInventory.java -part.java, line 4, adds import of ValidPartsInventory; -part.java, line 20, adds validation annotation to the Part class;

Step 6)

OutSourcedPartForm.HTML, line 22, changes field error to show class errors instead of just from the inv field; InhousePartForm.HTML, line 22, changes field error to show class errors instead of just from the inv field; InventoryMinMaxValidator.java, line 17-19, converts attributes inv,minInv,maxInv to Integer for logical tests; InventoryMinMaxValidator.java, line 20-21, creates various error messages for inventory minimum and inventory maximum warnings; InventoryMinMaxValidator.java, line 22-40, test if inventory drops below minimum or exceeds maximum, and assigns error message; EnufPartsValidator.java; line 36, changes required part inventory test to minumum inventory, to prevent new products from reducing inventory below required level.

BootStrapData.java, lines 44, 53, 62, 71, 80; changes company name of parts to be more realistic. BootStrapData.java, line 81, creates "soccer ball" as an available part.

Step 7)

src/test/java/com/example/demo/domain/PartTest.java, lines 153-160, creates test unit for minimum inventory field. src/test/java/com/example/demo/domain/PartTest.java, lines 161-168, creates test unit for maximum inventory field.

Step 8)

DeletePartValidator.java, file deleted because validator is unused;
