Exercise 23: Creating RESTFul Services - jkneal/spring-angular-train GitHub Wiki

Learn the basics of RESTFul services and how to create them using Spring MVC

1. In edu.train.shop.shopController, create a new method named 'getProduct' that maps to the path '/products/{id}' and accepts Http Get methods. This method should take the path variable 'id' as a argument (type should be Integer). Within the method, invoke the productRepository.findOne method passing the id. Return the product as a message response

2. Now refactor the controller edu.train.product.InventoryController to be a rest controller. To implement the methods use productRepository. Also make the following adjustments:

• Remove the method deleteProduct
• addProducts should accept Http Put methods, and after adding the product return all products
• searchProducts should invoke the method productRepository.findByNameMatching
• deleteProductById should map to the path '/inventory/{id}' and accept Http Delete methods. This method should also return ResponseEntity<Void>. Within the method, first check if the id given is a valid product (by using the productRepository). If the id is not valid, return the Http status code 404. Otherwise carry out the deletion and return 200

1. Start the training application and go to the app home page
2. Click on the link 'Ex 23 Get Product'. Verify the the JSON for product with id 1 is returned
3. Now go back to the menu and click on the link 'Ex 23 Get All'. Verify the JSON for all five products is returned.
4. Now go back to the menu and click on the link 'Ex 23 Add'. Verify you receive an alert with the message "Product added successfully"
5. Now click on the link 'Ex 23 Search'. Verify the JSON for products with names "Baseball" and "Basketball" is returned (with the products in that order)
6. Now go back to the menu and click on the link 'Ex 23 Delete'. Verify you receive an alert with the message "Product deleted successfully"
7. Now click on the link 'Ex 23 Delete Invalid'. Verify you receive an alert with the message "Error in request: status code: 404"
