Takeaways

• 😀 The video introduces how to set up a Spring Boot development environment using Cursor, with a focus on configuring the necessary tools for Java development.
• 😀 The presenter discusses the advantages of using Cursor over other IDEs, such as Intellij IDEA, highlighting features like AI-assisted coding with Claude Sonnet 3.5 and lower memory usage.
• 😀 The shift from GitHub Copilot to Cursor is mentioned, particularly because Cursor offers superior AI models and a more interactive experience compared to Copilot in IntelliJ IDEA.
• 😀 Memory management is a concern with larger projects, as IntelliJ IDEA tends to consume a significant portion of system memory, leading to potential performance issues.
• 😀 Cursor is introduced as a lightweight code editor that can handle various programming languages, including JavaScript, Python, and now, Spring Boot development.
• 😀 The tutorial walks through setting up Java and Spring Boot environments in Cursor, including the installation of Java and Spring Boot extension packs.
• 😀 The Spring Boot environment in Cursor supports Maven and Gradle as build tools, and the presenter opts for Maven based on personal preference.
• 😀 The demonstration uses the Spring Boot 'Pet Clinic' project to show how to clone, configure, and run a sample project in Cursor, highlighting key setup steps and debugging features.
• 😀 Basic debugging features in Cursor are compared to IntelliJ IDEA, with emphasis on breakpoints, stepping through code, and variable inspection during runtime.
• 😀 Cursor provides various navigation shortcuts for jumping between code definitions, references, and API endpoints, improving workflow efficiency for developers.
• 😀 The video showcases how Cursor can assist in creating a 'To-Do' RESTful API project using AI-generated code, including interaction with databases and testing via curl and HTTP client integrations.

Q & A

Why does the presenter choose to configure the Spring Boot development environment in Cursor instead of IntelliJ IDEA?

The presenter prefers Cursor over IntelliJ IDEA due to its AI-assisted model and plugins, better memory management, and a consistent development environment. Cursor supports Claude Sonnet 3.5, offers an improved Tab programming experience, and uses fewer system resources compared to IntelliJ IDEA.

What are the main differences between Github Copilot and Cursor in terms of AI-assisted coding?

Initially, Github Copilot provided AI assistance through its plugin for IDEA and VS Code. However, Cursor supports Claude Sonnet 3.5, which provides a better AI model experience, especially for those using VS Code. This shift attracted developers from VS Code to Cursor, but IDEA users did not have access to the new AI features until recently.

How does Cursor's memory usage compare to IntelliJ IDEA during development?

Cursor is more memory-efficient than IntelliJ IDEA, which often consumes 50% to 60% of system memory. The presenter, with 16 GB of memory, experiences less lag and system crashes while using Cursor for JavaScript and Python projects, making it a more practical choice for multiple projects.

What is the role of the Spring Boot Extension Pack in configuring the development environment on Cursor?

The Spring Boot Extension Pack provides the necessary plugins to configure the Spring Boot development environment. It requires the installation of the Java Extension Pack first, followed by the Spring Boot Extension Pack, which includes essential tools like Maven and Gradle support, as well as debugging tools.

What steps does the presenter take to install Java and Spring Boot extensions in Cursor?

The presenter first opens Cursor and searches for the 'Extension Pack for Java' to install the required Java tools. After that, they search for and install the 'Spring Boot Extension Pack', which includes the necessary plugins for Maven, Gradle, and Spring Boot development.

How does the presenter clone and run the 'Pet Clinic' example project in Cursor?

The presenter clones the 'Pet Clinic' project from a GitHub repository using the terminal in Cursor. After cloning, they open the project in Cursor and choose Maven as the build tool, as they are more familiar with it. The presenter confirms that the project runs correctly by launching it in debug mode and verifying that it starts on port 8080.

What debugging features does Cursor provide when developing a Spring Boot application?

Cursor offers several debugging features, such as setting breakpoints, stepping through code with 'Step Over' and 'Step Into' functions, and inspecting variables and method calls in real-time. These features make it easy to troubleshoot issues in the Spring Boot application, such as checking API responses or inspecting the state of objects.

What is the process for searching and navigating code in Cursor?

Cursor provides various code navigation shortcuts such as Command+Left Click to jump to a method or variable's definition, and Command+T followed by @ to list and search through all available APIs. Additionally, Command+P allows searching for files or actions within the codebase.

What is the purpose of the 'to-do' feature created by the presenter in Cursor, and how does it work?

The presenter demonstrates Cursor's ability to generate a 'to-do' RESTful API. Using AI, they create the necessary backend code to manage to-do items, including create, read, update, and delete (CRUD) operations. The presenter tests the API functionality using Curl and HTTP client plugins.

What problems did the presenter face while implementing the to-do API, and how were they resolved?

The presenter initially encountered an issue where the 'todos' table did not exist in the database. They resolved this by adjusting the Spring Boot configuration to automatically create the database schema ('create-drop') and successfully tested the API after restarting the application.
