Hotel Management System 🏬

(HMS) - Java with Hibernate ♨️

Welcome to our Hotel Management System project! 🎉 Building a Hotel Management System (HMS) in Java using Hibernate for CRUD operations is an excellent project for honing your skills in both Java programming and Hibernate ORM.

I'll guide you through the process step by step. Let's begin by crafting a well-structured Main class that serves as the entry point to our application. Additionally, this approach facilitates easy integration of more advanced features and functionalities as our Hotel Management System evolves.

Setup Instructions 🚀

To set up the project locally, follow these steps:

1. Clone the Repository:

   git clone <[email protected]:itsindrajput/Hotel-Management-System.git>
   

2. IDE Setup:

   • Open the project in your preferred IDE (e.g., Eclipse, IntelliJ IDEA).

3. Database Configuration:

   • Choose a database management system (DBMS) like MySQL, PostgreSQL, or H2.
   • Configure the database connection details in hibernate.cfg.xml.
   • This MySQL hibernate.cfg.xml example includes optional settings to generate and format SQL as well as an instruction to create database tables if any entity beans require them.

      <?xml version="1.0" encoding="UTF-8"?>
      <!DOCTYPE hibernate-configuration PUBLIC
            "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
            "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
      <hibernate-configuration>
         <session-factory>
            <!-- Database connection settings -->
            <property name="hibernate.connection.driver_class">com.mysql.cj.jdbc.Driver</property>
            <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/hotel_management</property>
            <property name="hibernate.connection.username">username</property>
            <property name="hibernate.connection.password">password</property>
            <property name="hibernate.hbm2ddl.auto">update</property>
   
            <!-- Hibernate dialect -->
            <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
   
            <!-- Enable Hibernate automatic session context management -->
            <property name="hibernate.current_session_context_class">thread</property>
   
            <!-- Specify the package to scan for entity classes -->
            <mapping class="org.example.model.Room"/>
            <mapping class="org.example.model.Guest"/>
            <mapping class="org.example.model.Invoice"/>
            <mapping class="org.example.model.Reservation"/>
         </session-factory>
      </hibernate-configuration>
   
   

4. Dependency Management:

   • Make sure to include these dependencies in your pom.xml if you're using Maven for dependency management. POM is an acronym for Project Object Model. The pom.xml file contains information of project and configuration information for the maven to build the project such as dependencies, build directory, source directory, test source directory, plugin, goals etc. Maven reads the pom. xml file, then executes the goal.

      <dependencies>
      <dependency>
         <groupId>junit</groupId>
         <artifactId>junit</artifactId>
         <version>3.8.1</version>
         <scope>test</scope>
      </dependency>
   
      <!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java -->
      <dependency>
         <groupId>mysql</groupId>
         <artifactId>mysql-connector-java</artifactId>
         <version>8.0.32</version>
      </dependency>
      <!-- https://mvnrepository.com/artifact/org.hibernate/hibernate-core -->
      <dependency>
         <groupId>org.hibernate</groupId>
         <artifactId>hibernate-core</artifactId>
         <version>6.1.7.Final</version>
      </dependency>
   </dependencies>
