SpringDoc 是一个基于 OpenAPI 3.0 规范的开源 API 文档生成工具,专为 Spring Boot 应用设计。它能自动扫描项目中的 REST 接口,生成标准化的 API 文档。

springdoc-openapi v1

由于springdoc v1和v2对应支持不同的springboot版本,所以我们拆分为两个部分做示例。

支持的springboot版本

Spring-boot (v1, v2 and v3)

maven引入

主要

springdoc-openapi-ui自带swagger界面,项目启动后路径:/swagger-ui.html

<dependency>
    <groupId>org.springdoc</groupId>
    <artifactId>springdoc-openapi-ui</artifactId>
    <version>1.8.0</version>
</dependency>

无UI界面

如果你只需要生成接口文档而不需要swagger界面,则引入核心依赖即可,接口文档路径:/v3/api-docs

<dependency>
    <groupId>org.springdoc</groupId>
    <artifactId>springdoc-openapi-webmvc-core</artifactId>
    <version>1.8.0</version>
</dependency>

JavaDoc支持

javadoc可以读取代码中的注释生成文档,不需要使用额外注解

<dependency>
    <groupId>org.springdoc</groupId>
    <artifactId>springdoc-openapi-javadoc</artifactId>
    <version>1.8.0</version>
</dependency>

注意:引入maven依赖后还需要添加maven插件才能生效

<build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <annotationProcessorPaths>
                        <path>
                            <groupId>com.github.therapi</groupId>
                            <artifactId>therapi-runtime-javadoc-scribe</artifactId>
                            <version>0.15.0</version>
                        </path>
                    </annotationProcessorPaths>
                </configuration>
            </plugin>
        </plugins>
</build>

注意!!如果项目中使用到了Lombok,则还需要同时引入lombok插件,否则会导致lombok不生效

<build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>${maven-compiler-plugin.version}</version>
                <configuration>
                    <annotationProcessorPaths>
                        <path>
                            <groupId>com.github.therapi</groupId>
                            <artifactId>therapi-runtime-javadoc-scribe</artifactId>
                            <version>${therapi-runtime-javadoc.version}</version>
                        </path>
                        <path>
                            <groupId>org.projectlombok</groupId>
                            <artifactId>lombok</artifactId>
                            <version>${lombok.version}</version>
                        </path>
                    </annotationProcessorPaths>
                </configuration>
            </plugin>
        </plugins>

依赖排除

我们在生产环境中并不需要使用到springdoc,所以我们可以将相关依赖全部排除,上线打包中只有项目相关的源码没有文档,我们在pom.xml中加入<profile>用于指定排除生产环境的依赖,生产打包时使用-P指定环境id即可:mvn clean package -P prod-env

<!-- 2. 配置 Profile,生产环境排除 springdoc -->
    <profiles>
        <!-- 测试环境(默认激活,保留 springdoc) -->
        <profile>
            <id>test-env</id>
            <activation>
                <activeByDefault>true</activeByDefault>
            </activation>
        </profile>

        <!-- 生产环境(激活时排除 springdoc) -->
        <profile>
            <id>prod-env</id>
            <activation>
