如何避免在swagger codegen接口中实现默认方法？

Question

我想避免在maven插件swagger codecen生成的接口中实现“默认”。例如，使用petstore swagger：http://petstore.swagger.io/v2/swagger.json

我用maven插件生成接口：

            <plugin>
            <groupId>io.swagger</groupId>
            <artifactId>swagger-codegen-maven-plugin</artifactId>
            <version>2.2.3</version>
            <executions>
                <execution>
                    <goals>
                        <goal>generate</goal>
                    </goals>
                    <configuration>
                        <inputSpec>./src/main/resources/swagger/api.yml</inputSpec>
                        <language>spring</language>
                        <generateSupportingFiles>false</generateSupportingFiles>
                        <configOptions>
                            <interfaceOnly>true</interfaceOnly>
                            <java8>true</java8>
                        </configOptions>
                    </configuration>
                </execution>
            </executions>
        </plugin>

我生成类似PetApi的接口。具有默认方法实现的java：

    default ResponseEntity<Void> addPet(@ApiParam(value = "Pet object that needs to be added to the store" ,required=true )  @Valid @RequestBody Pet body) {
    // do some magic!
    return new ResponseEntity<Void>(HttpStatus.OK);
    }

我想尽量避免

    ResponseEntity<Void> addPet(@ApiParam(value = "Pet object that needs to be added to the store" ,required=true )  @Valid @RequestBody Pet body);

有可能做到吗？

2020年3月更新：

根据新的OpenAPI工具openapi生成器
有一个带有Spring的选项（语言已弃用，使用GeneratorName）

跳过默认接口

根据留档，应解决以下问题：

<configOptions>
     <skipDefaultInterface>true</skipDefaultInterface>
</configOptions>

我决定配置同一个插件的两次执行。一个配置为仅生成模型类（java8=true，dateLibrary=java8 localdatetime），另一个配置为仅生成api接口（java=false，dateLibrary为空）。

            <generateApis>false</generateApis>
            <configOptions>

         <reactive>false</reactive>
         <interfaceOnly>true</interfaceOnly>
      </configOptions>
   </configuration>
   <dependencies>
      <dependency>

         <artifactId>swagger-codegen-generators</artifactId>

      </dependency>
   </dependencies>
</plugin>

注意：我使用的是插件的“v3”版本。

在“spring”语言中，“java8”参数既用于表示默认接口的使用，也用于表示java8的一般使用，例如在使用java8数据库时<相关票据：
