在 swagger maven 插件配置中包含 info 对象
Including info object in swagger maven plugin configuration

更新我按如下方式工作……在我的 pom.xml 中……

            <plugin>
            <groupId>io.swagger.core.v3</groupId>
            <artifactId>swagger-maven-plugin</artifactId>
            <version>2.0.9</version>                
            <configuration>
                <outputFileName>openapi</outputFileName>
                <outputPath>${project.build.directory}/openapi-json</outputPath>
                <outputFormat>JSONANDYAML</outputFormat>
                <resourcePackages>
                    <package>packageName.services</package>
                </resourcePackages>
                <configurationFilePath>${project.basedir}/openapi.yaml</configurationFilePath>              
            </configuration>
            <executions>
                <execution>
                    <phase>compile</phase>
                    <goals>
                        <goal>resolve</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

然后在单独的配置 YAML 文件中...

  openAPI:
  info:
    version: '1.0'
    title: API Documentation
    description: 'This is documentation for the Foosite API. You can find out more about FooSite at FooSite.org.'
    termsOfService: http://foosite.org/terms/
    license:
      name: Apache2.0
      url: http://www.apache.org/licenses/LICENSE-2.0.html
    contact:
      email: george@aol.com
prettyPrint: true

“info”标签应该在“apiSource”标签下，如下所示

<configuration>
    <apiSources>
        <apiSource>
            <springmvc>true</springmvc>
            <locations>com.xx.yyy.oooo</locations>
            <schemes>http,https</schemes>
            <host>@YYYY@</host>
            <basePath>@XXXX@</basePath>
            <info>

            </info>

在您的 JAX-RS 应用程序类中，使用@OpenAPIDefinition注释按照OpenAPI 规范的架构定义您的 swagger 信息：

package test.webapp.rest.application;

import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
    
import io.swagger.v3.oas.annotations.OpenAPIDefinition;
import io.swagger.v3.oas.annotations.servers.Server;
import io.swagger.v3.oas.annotations.info.Info;
@ApplicationPath("/rest/*")
@OpenAPIDefinition(
            info = @Info(title="This is my title", 
            description="This is my description", version="9.9.9"), 
            servers = @Server(url="http://localhost:8080/test-webapp-rest/rest"))
public class RESTApplication extends Application{
    ...
}

在你的 pom.xml 中，将这个 Application Class 的包添加到 swagger-maven-plugin 的“resourcePackages”中：

        <!-- GENERATE openapi.json in /src/main/webapp/swagger-ui-->
        <plugin>
            <groupId>io.swagger.core.v3</groupId>
            <artifactId>swagger-maven-plugin</artifactId>
            <version>2.1.5</version>
            <configuration>
                <outputFileName>openapi</outputFileName>
                <outputPath>${basedir}/src/main/webapp/swagger-ui</outputPath>
                <outputFormat>JSONANDYAML</outputFormat>
                <resourcePackages>
                    <package>test.webapp.rest.application</package>
                    <package>test.webapp.rest.resource</package>
                </resourcePackages>
                <prettyPrint>TRUE</prettyPrint>
            </configuration>
            <executions>
                <execution>
                    <phase>compile</phase>
                    <goals>
                        <goal>resolve</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

第二步是在 JSON 或 YAML 中生成信息的必要步骤：

{
  "openapi" : "3.0.1",
  "info" : {
    "title" : "This is my title",
    "description" : "This is my description",
    "version" : "9.9.9"
  },
  "servers" : [ {
    "url" : "http://localhost:8080/test-webapp-rest/rest",
    "variables" : { }
  } ],
  ...
}


openapi: 3.0.1
info:
  title: This is my title
  description: This is my description
  version: 9.9.9
servers:
- url: http://localhost:8080/test-webapp-rest/rest
  variables: {}
