无法使用 springdoc-openapi-maven-plugin 生成 Swagger.json 文件

Question

我正在尝试在 Maven 构建期间生成 Swagger.json 文件。

这是我在 pom.xml 中来自 docs 的插件。

<plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <id>pre-integration-test</id>
                        <goals>
                            <goal>start</goal>
                        </goals>
                    </execution>
                    <execution>
                        <id>post-integration-test</id>
                        <goals>
                            <goal>stop</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
            <plugin>
                <groupId>org.springdoc</groupId>
                <artifactId>springdoc-openapi-maven-plugin</artifactId>
                <version>0.2</version>
                <executions>
                    <execution>
                        <id>integration-test</id>
                        <goals>
                            <goal>generate</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                <apiDocsUrl>http://localhost:8080/registrationprocessor/v1/registrationstatus</apiDocsUrl>
                <outputFileName>openapi.json</outputFileName>
                <outputDir>${project.build.directory}</outputDir>
            </configuration>
            </plugin>

我看过这个repo。它在单独的项目中运行ning 很好，但是当我试图在我的项目中运行时。它给 java.net.ConnectException: Connection refused (Connection refused)

我已经尝试了 this Whosebug question and this github issue 的所有答案，但不幸的是，没有一个对我有用。

我们将不胜感激。

Answer 1

您的应用程序似乎不在运行端口 8080 上。请检查您的 Spring 配置，也许您设置了不同的端口？

Answer 2

Openapi.json 文件是在将 application.properties 的某些配置从 test 文件夹移动到 src 文件夹中的 bootstrap.properties 后生成的。但是每次我必须关闭端口 9001 才能生成 json 文件。
