Come faccio a dire swagger-codgen riguardo al mio generatore personalizzato?

Question

Sto provando a creare un generatore di codice swagger personalizzato basato sul generatore JAX-RS esistente. Ho seguito le indicazioni sulla pagina GitHub Swagger-Codegen e generato un modulo usando il comando moduli java -jar/swagger-codegen-cli/target/swagger-codegen-cli.jar meta -o output/myLibrary -n ABCCodegen -p com.abc.codegen. Ho creato i modelli di cui ho bisogno e ho aggiornato il file AbcCodegenGenerator.java.

Si verificano problemi quando si tenta di eseguire il codice. Il comando java -cp swagger-codegen-cli.jar: ABCCodegen-swagger-codegen-1.0.0.jar io.swagger.codegen.Codegen -l ABCCodegen -o ./test mi dà l'errore Impossibile trovare o caricare classe principale io.swagger.codegen.Codegen. Dopo aver esaminato i post su Swagger Google Group, ho provato a eseguire il comando java -cp ABCCodegen-swagger-codegen-1.0.0.jar -jar swagger-codegen-cli.jar langs. Tuttavia, il mio modulo personalizzato, abc, non viene visualizzato nell'elenco. C'è qualcosa che devo fare programmaticamente nella classe java per dire a codegen del mio generatore?

Ecco la mia classe AbcCodegenGenerator.java:

package com.abc.codegen; 



import io.swagger.codegen.*; 
import io.swagger.models.Operation; 
import io.swagger.codegen.languages.*; 

import java.util.*; 
import java.io.File; 



public class AbcCodegenGenerator extends AbstractJavaJAXRSServerCodegen { 
public AbcCodegenGenerator(){ 
    super(); 

    sourceFolder = "src/main/java"; 
     invokerPackage = "io.swagger.api"; 
     artifactId = "com.abc"; 
     outputFolder = "generated-code/ABCCodegen"; 

     modelTemplateFiles.put("model.mustache", ".java"); 

     //Classes for the API 
     apiTemplateFiles.put("api.mustache", ".java"); 
     apiTemplateFiles.put("apiService.mustache", ".java"); 
     apiTemplateFiles.put("apiServiceImpl.mustache", ".java"); 
     apiTemplateFiles.put("apiServiceFactory.mustache", ".java"); 
     apiPackage = "io.swagger.api"; 

     additionalProperties.put("title", title); 

     //The location templates will be read from 
     templateDir = "src/main/resources/ABCCodegen"; 



     //Adds ABCCodegen to the CliOptions list?? 
     CliOption library = new CliOption(CodegenConstants.LIBRARY, "library template (sub-template) to use"); 
     library.setDefault(DEFAULT_LIBRARY); 

     Map<String, String> supportedLibraries = new LinkedHashMap<String, String>(); 
     supportedLibraries.put(DEFAULT_LIBRARY, "abc"); 
     library.setEnum(supportedLibraries); 

     cliOptions.add(library); 
     cliOptions.add(new CliOption(CodegenConstants.IMPL_FOLDER, CodegenConstants.IMPL_FOLDER_DESC)); 
     cliOptions.add(new CliOption("title", "a title describing the application")); 
} 

@Override 
    public String getName() 
    { 
     return "abc"; 
    } 

    @Override 
    public String getHelp() 
    { 
     return "Generates a ABC Server application based on Jersey framework."; 
    } 

    @Override 
    public void postProcessModelProperty(CodegenModel model, CodegenProperty property) { 
     super.postProcessModelProperty(model, property); 
     if("null".equals(property.example)) { 
      property.example = null; 
     } 
    } 

    @Override 
    public void processOpts() { 
     super.processOpts(); 

     if (additionalProperties.containsKey(CodegenConstants.IMPL_FOLDER)) { 
      implFolder = (String) additionalProperties.get(CodegenConstants.IMPL_FOLDER); 
     } 

     supportingFiles.clear(); 
     writeOptional(outputFolder, new SupportingFile("pom.mustache", "", "pom.xml")); 
     writeOptional(outputFolder, new SupportingFile("README.mustache", "", "README.md")); 
     supportingFiles.add(new SupportingFile("ApiException.mustache", (sourceFolder + '/' + apiPackage).replace(".", "/"), "ApiException.java"));

     if (additionalProperties.containsKey("dateLibrary")) { 
      setDateLibrary(additionalProperties.get("dateLibrary").toString());

} 

vi ringrazio in anticipo per qualsiasi aiuto!

Answer 1

questo è come classi Java carichi, in particolare con SPI (Service Provider Interface).

C'è la documentazione qui:

https://github.com/swagger-api/swagger-codegen#making-your-own-codegen-modules

Il problema è che è necessario specificare sia la libreria così come il vaso Codegen, e dirgli quale classe a correre. Per esempio:

# assuming your library is under my-codegen/myLibrary/target 

java -cp my-codegen/myLibrary/target/myClientCodegen-swagger-codegen-1.0.0.jar \ 
    modules/swagger-codegen-cli/target/swagger-codegen-cli.jar \ 
    io.swagger.codegen.SwaggerCodegen generate \ 
    -l com.my.company.codegen.MyclientcodegenGenerator \ 
    -o foo \ 
    -i http://petstore.swagger.io/v2/swagger.json 

Questo aggiungerà la libreria codegen al classpath, la libreria modello personalizzato, eseguire la funzione main (io.swagger.codegen.SwaggerCodegen), e passare la classe come un obiettivo ..
