For this Project, I customized a Spring Framework application with an HTML front-end and a Java backend. I was given a UML class diagram and asked to create an inventory application for a business. I created a sample inventory, buy now and delete product buttons and reflected the changes in the connected database. I used Validators to enforce a maximum and minimum inventory and displayed error messages if inventory fell outside of those bounds. Finally I created Unit tests for the maximum and minimum fields

C. Customize the HTML user interface for your customer’s application. The user interface should include the shop name, the product names, and the names of the parts. Changed My Bicycle shop to My Guitar Shop on line number 14 in mainscreen.html Changed Shop to Guitar Shop on line 19 in mainscreen.html Changed Parts to Guitar Parts on line number 21 in mainscreen.html

added link to demo.css on line 11 in about.html added link to demo.css on line 13 in mainscreen.html

E. Add a sample inventory appropriate for your chosen store to the application. You should have five parts and five products in your sample inventory and should not overwrite existing data in the database.

added line 31 in BootStrapData.java to add InhousePartRespository changed line 34 to include InhousePartRepository in BootStrapData.java added line 38 in BootStrapData.java to include InhousePartRepository added line 44 to have if statement to check if partRespository is empty before adding parts in BootStrapData.java

changed line 45 in BootStrapData.java to add new outsourced part called strings changed line 46 in BootStrapData.java to set part name to Guitar Strings changed line 47 in BootStrapData.java to change inventory to 40 changed line 48 in BootStrapData.java to set price to 10 changed line 49 in BootStrapData.java to set Id to 100L changed line 50 in BootStrapData.java to save string to inhousePartRepository added lines 52-57 in BootStrapData.java to add headstock to inhousePartRepository added lines 59-65 to add outsourced part called Body in BootStrapData.java added lines 67-73 to add outsourced part called Tuning Pegs in BootStrapData.java added lines 75-81 to add outsourced part called Guitar Knobs in BootStrapData.java

added if statement to line 86 to check if product repo is empty in BootStrapData.java added lines 87-91 to create 5 new products in BootStrapData.java added lines 92-96 to save products in BootStrapData.java

added style to lines 11-34 in about.html instead of linking css (trying to make sure bootstrap css is showing up) added style to lines 13-36 in mainscreen.html instead of linking css (trying to make sure bootstrap css is showing up)

changed lines 71-115 back to original code in mainscreen.html (I thought part C wanted me to hard code in parts, I realize that was a mistake.) changed lines 143 - 187 back to original code in mainscreen.html (same thing, thought that part c wanted me to hard code in products.)

F. Add a “Buy Now” button to your product list. Your “Buy Now” button must meet each of the following parameters: • The “Buy Now” button must be next to the buttons that update and delete products. • The button should decrement the inventory of that product by one. It should not affect the inventory of any of the associated parts. • Display a message that indicates the success or failure of a purchase.

added line 114 in mainscreen.html to include buy now button create buyNowSuccess.html to indicate success of purchase created nuyNowFailure.html to indicate failure of purchase changed line 5 title in buyNowSuccess.html and buyNowFailure.html to Buy Now Success and Buy Now Failure added h1 tag on line 8 in buyNowSuccess.html to display success message added link on line 9 in buyNowSuccess.html to link to mainscreen.html added h1 tag on line 8 in buyNowFailure.html to display failure message added link on line 9 in buyNowFailure.html to link to mainscreen.html created a BuyProductController to handle request from button in mainscreen.html added lines 16 and 17 in BuyProductController to inject ProductRepository added lines 19-21 to Getmapping for /buyProduct in BuyProductController and create optional product variable added lines 23 - 35 to include if/else statements to check if product inventory is greater than 0 and decrement and return buyNowSuccess if it is. If Product inventory 0 or product not found return buyNowFailure.html

G. Modify the parts to track maximum and minimum inventory by doing the following: • Add additional fields to the part entity for maximum and minimum inventory. • Modify the sample inventory to include the maximum and minimum fields. • Add to the InhousePartForm and OutsourcedPartForm forms additional text inputs for the inventory so the user can set the maximum and minimum values. • Rename the file the persistent storage is saved to. • Modify the code to enforce that the inventory is between or at the minimum and maximum value.

added lines 31-34 in Part.java to add fields and Minimum for Max and Min inventory for parts changed line 53 in Part.java to add minInv and maxInv to constructor added lines 49-50 to set default values for maxInv and minInv in Part.java added lines 18-19 in OutsourcedPart.java to set default for max and min added lines 18-19 in InhousePart.java to set default for max and min added lines 58-59 to set default values for maxInv and minInv w additional constructor in Part.java added lines 92-104 in Part.java to include getters and setters for maxInv and minInv added lines 50-51, 59-60, 69-70, 79-80, and 89-90 to include max and minimum fields for sample inventory in BootStrapData.java added lines 24-28 in InhousePartForm.html to include max and min text inputs so user can set the maximum and minimum values. added lines 25-29 in OutsourcedPartForm.html to include max and min text inputs so user can set the maximum and minimum values. added lines 67 and 68 to add min and max inv to table headings in mainscreen.html added line 77 and 78 in mainscreen.html to show min and max inv in table renamed database to kate_favre_d287_db on line 6 in application.properties added @max on line 31 in Part.java to make sure inventory is between or at min and max added @min on line 33 in Part.java to make sure inventory is greater than min added @min and @max on lines 35-36 in Part.java to make sure inventory is between min and max

H. Add validation for between or at the maximum and minimum fields. The validation must include the following: • Display error messages for low inventory when adding and updating parts if the inventory is less than the minimum number of parts. • Display error messages for low inventory when adding and updating products lowers the part inventory below the minimum. • Display error messages when adding and updating parts if the inventory is greater than the maximum.

• Display error messages for low inventory when adding and updating parts if the inventory is less than the minimum number of parts: created MinimumValidator.java and ValidMinimum.java to add validation for minimum fields added lines 11-13 in MinimumValidator to set up custom annotation and @autowired for access to springbeans lines 15-17 in MinimumValidator.java for optional initialization method lines 19-22 in MinimumValidator.java logic to check inv is greater than min inv line 10 ValidMinimum.java link annotation to Validation class lines 11-12 in ValidMinimum set target (Part class) and makes sure available during runtime lines 13-17 in ValidMinimum.java set error message if validation fails line 21 added @ValidMinimum to Part.java added lines 33-37 in outsourcedPartForm.html to check for validation errors in form and display error messages added lines 32-36 in InhousePartForm.html to check for validation errors in form and display error messages

• Display error messages for low inventory when adding and updating products lowers the part inventory below the minimum: added lines 37-38 to EnufPartsValidator.java to check if updating products lowers part inventory below minimum updated line 20 in ValidEnufParts.java to display error message added lines 53-56 in ProductServiceImpl.java to display error message if product inventory is lower than min Inv added line 27 @ValidEnufParts annotation to AddProductController.java to check if adding or updating product makes part go below min added line 32 in EnufPartsValidator (was getting errors on running app about myContext and I realized I needed to add assignment) added line 43-47 in EnufPartsValidator.java to check if there are enough parts to add an amount of products and display an error message if not fixed line 21 in MinimumValidator.java to include >= instead of just > (because part can be equal to min but not less than equal)

• Display error messages when adding and updating parts if the inventory is greater than the maximum: created MaximumValidator.java and ValidMaximum.java to add validation for maximum fields added lines 10-12 in MaximumValidator.java to set up custom annotation and @autowired for access to springbeans lines 14-17 in MaximumValidator.java for optional initialization method lines 18-21 in MaximumValidator.java logic to check inv is less than or equal to max inv line 10 ValidMaximum.java link annotation to Validation class lines 11-12 in ValidMaximum set target (Part class) and makes sure available during runtime lines 13-17 in ValidMaximum.java set error message if validation fails line 22 added @ValidMaximum to Part.java

I. Add at least two unit tests for the maximum and minimum fields to the PartTest class in the test package. lines 30-37 in PartTest.java created test for getMaxInv tested for partIn and partOut lines 38-45 in PartTest.java created test for setMaxInv tested for partIn and PartOut lines 46-53 in PartTest.java created test for setMinInv tested for partIn and PartOut lines 54-61 in PartTest.java created test for setMinInv tested for partIn and PartOut

J. Remove the class files for any unused validators in order to clean your code. removed DeletePartValidator.java because it was unused

*** changed create-drop back to update in application properties

*** updating returned submission for part H *** (I also included these in part H above) added line 32 in EnufPartsValidator (was getting errors on running app about myContext and I realized I needed to add assignment) removed @max from lines 35 and line 40 from Part.java (realized it was hard coding a max) added lines 33-37 in outsourcedPartForm.html to check for validation errors in form and display error messages added lines 32-36 in InhousePartForm.html to check for validation errors in form and display error messages added line 43-47 in EnufPartsValidator.java to check if there are enough parts to add an amount of products and display an error message if not fixed line 21 in MinimumValidator.java to include >= instead of just > (because part can be equal to min but not less than equal) changed line 11 to uncommented in application.properties changed line 12 to commented out in application.properties
