0.2 Creating a Spring Boot 3 Project<\/h2>\n<\/header>\n
\n

1. What is Spring Boot?<\/h3>\n

Spring Boot is a framework for easily building Java-based web applications and RESTful web services. It is an enhanced version of the traditional Spring Framework, helping developers to quickly develop applications with minimal setup and without complex configuration processes.<\/p>\n

Spring Boot offers various pre-configured libraries and starter packages, enabling rapid prototyping and simple deployment. By following the ‘Convention over Configuration’ principle, developers can focus more on business logic.<\/p>\n<\/section>\n

\n

2. Setting Up the Development Environment<\/h3>\n

To use Spring Boot 3, you need the Java Development Kit (JDK) and either Maven or Gradle. JDK version 17 or higher is required, and it is recommended to use IDEs like IntelliJ IDEA or Eclipse.<\/p>\n

2.1 Installing the JDK<\/h4>\n
    \n
  1. JDK Download: Visit the Oracle JDK download page<\/a>.<\/li>\n
  2. Select and download the JDK according to your operating system.<\/li>\n
  3. After installation, add the environment variable. For Windows, set JAVA_HOME to the JDK installation path in System Properties -> Advanced System Settings -> Environment Variables.<\/li>\n<\/ol>\n

    2.2 Installing the IDE<\/h4>\n

    IntelliJ IDEA has both free and paid versions, and the free Community Edition is sufficient. After downloading and installing, you can add Maven or Gradle as plugins.<\/p>\n<\/section>\n

    3. Creating a Spring Boot 3 Project<\/h3>\n

    Now, let’s create a Spring Boot 3 project. There are two ways to create a project: using Spring Initializr or through an IDE.<\/p>\n

    3.1 Creating a Project with Spring Initializr<\/h4>\n
      \n
    1. \n

      Access Spring Initializr<\/a>.<\/p>\n<\/li>\n

    2. \n

      Select either Maven Project or Gradle Project for the Project type.<\/p>\n<\/li>\n

    3. \n

      Select Java for the Language.<\/p>\n<\/li>\n

    4. \n

      Choose Spring Boot version 3.0.0 or higher.<\/p>\n<\/li>\n

    5. \n

      Input the Project Metadata, including Group, Artifact, Name, Description, and Package Name.<\/p>\n<\/li>\n

    6. \n

      Select necessary libraries from Dependencies. Add libraries like Web, JPA, H2, etc.<\/p>\n<\/li>\n

    7. \n

      Click the Generate button to download the ZIP file, and then extract it to your desired location.<\/p>\n<\/li>\n<\/ol>\n

      3.2 Creating a Project through the IDE<\/h4>\n
        \n
      1. Open IntelliJ IDEA and select File > New > Project.<\/li>\n
      2. Select Spring Initializr and proceed to the next steps. Set up Group, Artifact, and Dependencies.<\/li>\n
      3. Click Finish to create the project.<\/li>\n<\/ol>\n

        3.3 Project Structure<\/h4>\n

        The basic structure of the created project is as follows:<\/p>\n
