Walkthrough

The update introduces a centralized ChatService to streamline chat functionalities, reducing direct interactions between the ChatController and clients (ChatClient, EmbeddingClient). It enhances the chat system with methods for handling various chat scenarios and RAG generation. Additionally, a new dataset of restaurant information is added, alongside a template for document-based chat responses.

Changes

File Path	Change Summary
.../controller/ChatController.java	Updated to use ChatService for chat functionalities and added ragGenerate method.
.../service/ChatService.java	New service class for AI chat interactions, including chat processing and RAG generation.
.../resources/data/restaurants.json	Added restaurant information dataset.
.../resources/rag-prompt-template.st	Introduced a template for document-based chat responses.
.../controller/ChatControllerTest.java	Updated tests with HttpStatus.SC_OK, added JSON content type assertions, and a new test method ragWithSimpleStore.

🐰✨
In the realm of code, under the digital sky,
A change was made, oh me, oh my!
With ChatService now leading the play,
Our chats are smarter, day by day.
So here's to the team, with brains so bright,
Making our digital world a delight!

Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

CodeRabbit Commands (invoked as PR comments)

• @coderabbitai pause to pause the reviews on a PR.
• @coderabbitai resume to resume the paused reviews.
• @coderabbitai review to trigger a review. This is useful when automatic reviews are disabled for the repository.
• @coderabbitai resolve resolve all the CodeRabbit review comments.
• @coderabbitai help to get help.

Additionally, you can add @coderabbitai ignore anywhere in the PR description to prevent this PR from being reviewed.

CodeRabbit Configration File (.coderabbit.yaml)

• You can programmatically configure CodeRabbit by adding a .coderabbit.yaml file to the root of your repository.
• Please see the configuration documentation for more information.
• If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: # yaml-language-server: $schema=https://coderabbit.ai/integrations/schema.v2.json

1-9: LGTM! The RAG prompt template is well-structured and aligns with the objectives of enhancing response generation capabilities.

chatmodel-springai/src/main/java/com/example/ai/controller/ChatController.java (5)

19-22: Ensure ChatService is properly annotated with @Autowired or passed through constructor injection for maintainability and consistency with Spring's dependency injection principles.

---

27-52: The delegation of chat functionalities to ChatService simplifies the controller and centralizes business logic, aligning with best practices for clean architecture.

---

50-52: Consider adding error handling for external service calls within ChatService methods to ensure robustness and reliability of the chat functionalities.

---

50-52: Adding logging for incoming requests and responses can enhance observability and debugging capabilities.

---

50-52: The new ragGenerate method introduces RAG functionality as intended. Ensure comprehensive testing to validate its integration and functionality.

chatmodel-springai/src/test/java/com/example/ai/controller/ChatControllerTest.java (2)

38-39: Using HttpStatus.SC_OK constant and asserting JSON content type improves readability and maintainability of the tests.

---

79-89: The new test method ragWithSimpleStore effectively covers querying restaurant information using the RAG feature. Ensure it includes negative test cases and edge cases for comprehensive coverage.

chatmodel-springai/src/main/resources/data/restaurants.json (1)
