Project purpose

This project is a simplified internet shop.

---

This internet shop performs these basic functions:

• Registration, log in forms and logout
• Shopping cart and order services
• Two roles: User and Admin

---

This project has authentication and authorization filters, DAO and Service layers, Servlets and JSP pages.

DAO layer has two implementations: inner storage based on List and outer storage based on MySQL DB.

Project structure

• Java 11
• Maven
• MavenCheckstylePlugin 3.1.1
• javax.servlet 3.1.0
• javax.jstl 1.2
• mysql-connector-java 8.0.20
• log4j 1.2.17

For developer

To run this project you need to install:

• Java 11
• Tomcat
• MySQL (can use another RDBMS)

---

Add this project to your IDE as Maven project.

Add Java SDK 11 in project structure.

Configure Tomcat:

• Add war
• Add Java SDK 11

Change a path to your Log file in src/main/resources/log4j.properties on line 12.

---

To work with MySQL you need to:

• Use file src/main/resources/init_db.sql to create schema and all the tables required by this app in MySQL DB
• Change username and password to match with MySQL in src/main/java/mate/academy/internet/shop/util/ConnectionUtil.java class on 19 and 20 lines

---

To work with inner Storage you need to:

• Need to remove annotation @Dao from classes :
  1. src/main/java/mate/academy/internet/shop/dao/jdbc/OrderDaoJdbcImpl.java
  2. src/main/java/mate/academy/internet/shop/dao/jdbc/ProductDaoJdbcImpl.java
  3. src/main/java/mate/academy/internet/shop/dao/jdbc/ShoppingCartDaoJdbcImpl.java
  4. src/main/java/mate/academy/internet/shop/dao/jdbc/UserDaoJdbcImpl.java
• Need to add annotation @Dao to classes :
  1. src/main/java/mate/academy/internet/shop/dao/impl/OrderDaoImpl.java
  2. src/main/java/mate/academy/internet/shop/dao/impl/ProductDaoImpl.java
  3. src/main/java/mate/academy/internet/shop/dao/impl/ShoppingCartDaoImpl.java
  4. src/main/java/mate/academy/internet/shop/dao/impl/UserDaoImpl.java

The class src/main/java/mate/academy/internet/shop/lib/Injector.java checks all classes in all packages and checks the annotation over the class name and selects the desired classes that implements the interfaces

---

Run the project:

Main page is at URL: .../{context_path}

For MySQL DAO only on first run of the project, for inner Storage on every launch, to create default users open URL: .../{context_path}/injectData

By default there are two users with an USER role (name = "Bob", login = "bob", password = "1"), (name = "Alisa", login = "alisa", password = "1")
one with an ADMIN role (login = "admin", password = "3"),
