Generate SpringBoot API Docs Instantly with JApiDocs – No Annotations Needed

JApiDocs is a SpringBoot API documentation generation tool that works out‑of‑the‑box without requiring additional annotations.

Writing and maintaining API docs is a tedious but unavoidable task for backend developers; JApiDocs provides a convenient wheel to automate this process and save time.

Generated documentation looks like the following:

Compared with Swagger, which requires many annotations, and Spring RestDocs, which needs test cases, JApiDocs integrates painlessly and lets you start using it within minutes.

Quick Start

To make JApiDocs work correctly, your code should follow the pattern below:

/**
 * User API
 */
@RequestMapping("/api/user/")
@RestController
public class UserController {
    /**
     * User list
     * @param listForm
     */
    @RequestMapping(path = "list", method = {RequestMethod.GET, RequestMethod.POST})
    public ApiResult<PageResult<UserVO>> list(UserListForm listForm){
        return null;
    }

    /**
     * Save user
     * @param userForm
     */
    @PostMapping(path = "save")
    public ApiResult<UserVO> saveUser(@RequestBody UserForm userForm){
        return null;
    }
}

Annotate controller classes and methods with necessary comments and return types; JApiDocs will parse this information. Use @param to describe method parameters, which IDE assistance makes easy.

Then execute the following code in any main entry point to generate the documentation:

DocsConfig config = new DocsConfig();
config.setProjectPath("your springboot project path"); // project root
config.setProjectName("ProjectName"); // project name
config.setApiVersion("V1.0"); // API version
config.setDocsPath("your api docs path"); // output directory
config.setAutoGenerate(Boolean.TRUE); // enable auto‑generation
Docs.buildHtmlDocs(config); // generate docs

After that, just keep writing code; JApiDocs will handle the API documentation automatically, eliminating the need for manual maintenance.

Feature Highlights

Code‑as‑Documentation: Parses SpringBoot source directly, requiring only standard controller syntax and reasonable comments.

HTML Export: Provides convenient navigation and interface view, with local preview or deployment to an HTTP server for front‑back collaboration.

Client Model Sync: Can export Android Java and iOS Objective‑C model code, reducing duplicate work for front‑end developers.

Additional Features: Interface search, multi‑version and English docs, custom extensions, etc.

Concise Documentation

A great tool is useless without clear docs; JApiDocs offers a minimal guide that lets you get started in under five minutes, freeing you to focus on more valuable tasks.
