Smart-Doc Project

Introduce

smart-doc is a tool that supports both JAVA REST API and Apache Dubbo RPC interface document generation. Smart-doc is based on interface source code analysis to generate interface documents, and zero annotation intrusion. You only need to write Javadoc comments when developing, smart-doc can help you generate Markdown or HTML5 document. smart-doc does not need to inject annotations into the code like Swagger.

Features

Zero annotation, zero learning cost, only need to write standard JAVA document comments.
Automatic derivation based on source code interface definition, powerful return structure derivation support.
Support Spring MVC, Spring Boot, Spring Boot Web Flux (Not support endpoint), Feign.
Supports the derivation of asynchronous interface returns such as Callable, Future, CompletableFuture.
Support JSR-303 parameter verification specification.
Support for automatic generation of request examples based on request parameters.
Support for generating JSON return value examples.
Support for loading source code from outside the project to generate field comments (including the sources jar package).
Support for generating multiple formats of documents: Markdown,HTML5,Asciidoctor,Postman Collection 2.0+,OpenAPI 3.0.
Support for exporting error codes and data dictionary codes to API documentation.
The debug html5 page fully supports file upload and download testing.
Support Apache Dubbo RPC.

Best Practice

smart-doc + Torna form an industry-leading document generation and management solution, using smart-doc to complete Java source code analysis and extract annotations to generate API documents without intrusion, and automatically push the documents to the Torna enterprise-level interface document management platform.

Getting Started

Smart-doc Samples。

# git clone https://github.com/shalousun/smart-doc-demo.git

This example already provides a static html document generated in advance. You can start the Spring Boot project and then go directly to http://localhost:8080/doc/api.html to view the interface documentation generated by smart-doc. Of course, you can also browse http://localhost:8080/doc/api.html, which looks a html like generated by asciidoctor-maven-plugin plugin.

Add Maven Plugin

Add smart-doc-maven-plugin in your pom.xml.

<plugin>
    <groupId>com.github.shalousun</groupId>
    <artifactId>smart-doc-maven-plugin</artifactId>
    <version>[latest]</version>
    <configuration>
        <!--Specify the configuration file used to generate the document-->
        <configFile>./src/main/resources/smart-doc.json</configFile>
        <!--smart-doc implements automatic analysis of the dependency tree to load the source code of third-party dependencies. If some framework dependency libraries are not loaded, an error is reported, then use excludes to exclude-->
        <excludes>
            <!--The format is: groupId: artifactId; refer to the following-->
            <exclude>com.google.guava:guava</exclude>
        </excludes>
        <!--Since version 1.0.8, the plugin provides includes support-->
        <!--smart-doc can automatically analyze the dependency tree to load all dependent source code. In principle, it will affect the efficiency of document construction, so you can use includes to let the plugin load the components you configure.-->
        <includes>
            <!--The format is: groupId: artifactId; refer to the following-->
            <include>com.alibaba:fastjson</include>
        </includes>
    </configuration>
    <executions>
        <execution>
            <!--Comment out phase if you don't need to start smart-doc when compiling-->
            <phase>compile</phase>
            <goals>
                <!--smart-doc provides html, openapi, markdown, adoc and other goals-->
                <goal>html</goal>
            </goals>
        </execution>
    </executions>
</plugin>

Configuration

Create a JSON configuration file in your project. The smart-doc-maven-plugin plugin will use this configuration information. For example, create /src/main/resources/smart-doc.json in the project. The configuration contents are as follows.

Minimize configuration:

{
   "allInOne": true, // whether to merge documents into one file, generally recommended as true
   "isStrict": false,//If the strict mode is set to true, Smart-doc forces that the public method in each interface in the code has a comment.
   "outPath": "src/main/resources/static/doc" //Set the api document output path.
}

Only the above three simple configuration items can make smart-doc-maven-plugin work. In fact, only the outPath configuration item is necessary.

Detailed configuration content:

When you need to use smart-doc to generate more API document information, you can add detailed configuration content.

{
  "serverUrl": "http://127.0.0.1", // Set the server address, not required
  "pathPrefix": "", //Set the path prefix,not required。eg: Servlet ContextPath

Note: This JSON configuration can be converted into JSON using smart-doc's ApiConfig Object. So the project configuration can also refer to the introduction of smart-doc.

Generated document

Run Plugin with MAVEN command

// Generate html
mvn -Dfile.encoding=UTF-8 smart-doc:html
// Generate markdown
mvn -Dfile.encoding=UTF-8 smart-doc:markdown
// Generate adoc
mvn -Dfile.encoding=UTF-8 smart-doc:adoc
// Generate postman collection
mvn -Dfile.encoding=UTF-8 smart-doc:postman
// Generate document and send to Torna
mvn -Dfile.encoding=UTF-8 smart-doc:torna-rest

// Apache Dubbo RPC
// Generate html
mvn -Dfile.encoding=UTF-8 smart-doc:rpc-html
// Generate markdown
mvn -Dfile.encoding=UTF-8 smart-doc:rpc-markdown
// Generate adoc
mvn -Dfile.encoding=UTF-8 smart-doc:rpc-adoc
// Push dubbo rpc document to Torna
mvn -Dfile.encoding=UTF-8 smart-doc:torna-rpc

Note: Under the window system, if you use the maven command line to perform document generation, non-English characters may be garbled, so you need to specify -Dfile.encoding = UTF-8 during execution.
