如何避免 swagger codegen 接口中的默认方法实现？

Question

我想避免 "default" 在 maven 插件 swagger codegen 生成的接口中实现。例如，宠物店大摇大摆：http://petstore.swagger.io/v2/swagger.json

我用 maven 插件生成界面 :

            <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>

我使用方法的默认实现生成类似 PetApi.java 的接口：

    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);
    }

我想避免这样

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

可以吗？

Update March 2020:

According to new OpenAPI Tool openapi-generator
There is an option with spring (language is DEPRECATED, use generatorName)

skipDefaultInterface

Answer 1

对于 "spring" 语言，"java8" 参数既用于指示默认接口的使用，也用于指示 Java8 的一般使用，例如当使用 Java8 日期库时。

Answer 2

我在从 swagger codegen 派生的项目中使用 < java8 > false < /java8 > 设法避免了这些默认方法：https://github.com/OpenAPITools/openapi-generator

适合我的示例：

<plugin>
    <groupId>org.openapitools</groupId>
    <artifactId>openapi-generator-maven-plugin</artifactId>
    <version>4.0.0</version>
    <executions>
        <execution>
            <goals>
                <goal>generate</goal>
            </goals>
            <configuration>
                <inputSpec>${maven.multiModuleProjectDirectory}/api/target/generated/swagger-api-spec/swagger.json</inputSpec>  
                            <language>spring</language>
                            <library>spring-boot</library>
                <skipValidateSpec>true</skipValidateSpec>
                <generateSupportingFiles>true</generateSupportingFiles>
                <configOptions>
                    <sourceFolder>src/gen/java/main</sourceFolder>
                    <java8>false</java8>
                    <dateLibrary>java8</dateLibrary>
                    <interfaceOnly>false</interfaceOnly>
                    <groupId>com.company.groupid</groupId>
                    <artifactId>${project.artifactId}</artifactId>
                    <artifactVersion>${project.version}</artifactVersion>
                </configOptions>
            </configuration>
        </execution>
    </executions>
</plugin>

我解决了配置同一插件的两次执行。一个配置为仅生成模型类（java8=true 和 dateLibrary=java8-localdatetime），另一个配置为仅生成 api 接口（java =false 和 dateLibrary 为空）。

<plugin>
   <groupId>io.swagger.codegen.v3</groupId>
   <artifactId>swagger-codegen-maven-plugin</artifactId>
   <version>3.0.8</version>
   <executions>
      <execution>
         <id>gera-api-model</id>
         <goals>
            <goal>generate</goal>
         </goals>
         <configuration>
            <inputSpec>${project.basedir}/src/main/openapi-spec/openapi.yaml</inputSpec>
            <language>spring</language>

            <generateModels>true</generateModels>
            <generateApis>false</generateApis>
            <configOptions>
               <dateLibrary>java8-localdatetime</dateLibrary>
               <java8>true</java8> 
             </configOptions>
         </configuration>
      </execution>

         <id>gera-api-interface</id>
         <goals>

         </goals>
         <configuration>
            <inputSpec>${project.basedir}/src/main/openapi-spec/openapi.yaml</inputSpec>
            <language>spring</language>
            <generateModels>false</generateModels>
            <generateApis>true</generateApis>
            <configOptions>
               <java8>false</java8>
            </configOptions>
         </configuration>
      </execution>
   </executions>
   <configuration>
      <inputSpec>${project.basedir}/src/main/openapi-spec/openapi.yaml</inputSpec>

      <generateSupportingFiles>false</generateSupportingFiles>
      <generateApiTests>false</generateApiTests>
      <generateModelTests>false</generateModelTests>
      <configOptions>
         <bigDecimalAsString>true</bigDecimalAsString>
         <serializableModel>true</serializableModel>
         <reactive>false</reactive>
         <interfaceOnly>true</interfaceOnly>
      </configOptions>
   </configuration>
   <dependencies>
      <dependency>
         <groupId>io.swagger.codegen.v3</groupId>
         <artifactId>swagger-codegen-generators</artifactId>
         <version>1.0.8</version>
      </dependency>
   </dependencies>
</plugin>

注意：我使用的插件版本'v3'。

根据 documentation 下面应该解决它：

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