The purpose of this project is to create a microservice to manage the categories and products of an e-commerce oriented to sellers who want to expose their product through manomano.
This project is a Java microservice with Spring Boot in which the dependency management is done through Maven. The
project consists of three layers; controller, service and persistence layer. The project is documented by swagger and
the contract (swagger.yml file) is in OpenApi 3.0.2 version. The controller interface is generated automatically
when compiling the project through a maven plugin. In the service layer there is a mapper whose function is to map
the records obtained from the database in the response object also defined in the contract. The persistence layer
is done using JPA and spring data jpa library. The database is an H2 memory database for which there is an
autoloading file data.sql in the path resources/data.sql
.
Once the microservice starts, you can access the swagger GUI and H2 console using the following paths:
http://localhost:8082/swagger-ui.html#/
http://localhost:8082/h2-console
The database credentials are in the file application.yml
##Tasks
-
Create a new entity named CategorizationType with the following attributes: id (numeric type), type (text string), desc (text string) and associate it to the existing entity Product knowing that a category can have n products.
-
Create the following categorization type inserts in the data.sql script associated with the entity created in step 1:
| CATEGORIZATION_ID | TYPE | DESCRIPTION | | :-------------: |:-------------:| :-----:| | 1 | B2B | Business-to-Business | | 2 | B2C | Business-to-Consumer | | 3 | C2C | Consumer-to-Consumer |
-
Modify the contract to pass as query param the categorization identifier and the minimum price. Also modify the response object in the contract so that it returns the categorization type as well as the description.
-
Create an object in the directory
controller/dto
that contains the data to be passed via the controller's getProducts method. -
Create the service to obtain all the products filtering by type of categorization, price greater than a given price and date given between startDate and endDate of the product through the Repository ProductRepository.
-
Create a unit test in the class
unittest/ProductControllerUnitTest
to check that if no mandatory parameters are passed, return an HTTP 400 BAD REQUEST and execute it. -
Create the integration test in the
Integrationtest/ProductControllerIntegrationTest
class that returns all products and run it passing as filters:fecha = 2021-04-14 00:00:00 categorizationId = 1 minPrice = 50.00
-
Compare that the same result is obtained in the following ways:
- Running the test manually.
- Using the maven command necessary to pass the tests.
- Compile, package, start the jar and Perform the necessary query from the H2 console.
