java - 我如何告诉 swagger-codegen 我的自定义生成器?

我正在尝试基于现有的 JAX-RS 生成器制作自定义 swagger 代码生成器。我按照 Swagger-Codegen GitHub 页面上的说明使用命令 java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar meta -o output/myLibrary -n ABCCodegen 生成了一个模块-p com.abc.codegen。我创建了我需要的模板并更新了 AbcCodegenGenerator.java 文件。

我在尝试运行代码时遇到了问题。命令 java -cp swagger-codegen-cli.jar:ABCCodegen-swagger-codegen-1.0.0.jar io.swagger.codegen.Codegen -l ABCCodegen -o ./test 给我错误无法找到或加载主类 io.swagger.codegen.Codegen。查看 Swagger Google Group 上的帖子后,我尝试运行命令 java -cp ABCCodegen-swagger-codegen-1.0.0.jar -jar swagger-codegen-cli.jar langs。但是,我的自定义模块 abc 没有出现在列表中。我需要在 java 类本身中以编程方式做些什么来告诉 codegen 我的生成器吗?

这是我的类 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"));
supportingFiles.add(new SupportingFile("ApiOriginFilter.mustache", (sourceFolder + '/' + apiPackage).replace(".", "/"), "ApiOriginFilter.java"));
supportingFiles.add(new SupportingFile("ApiResponseMessage.mustache", (sourceFolder + '/' + apiPackage).replace(".", "/"), "ApiResponseMessage.java"));
supportingFiles.add(new SupportingFile("NotFoundException.mustache", (sourceFolder + '/' + apiPackage).replace(".", "/"), "NotFoundException.java"));

supportingFiles.add(new SupportingFile("BadRequestException.mustache", (sourceFolder + '/' + apiPackage).replace(".", "/"), "BadRequestException.java"));
supportingFiles.add(new SupportingFile("JavaRestResourceUtil.mustache", (sourceFolder + '/' + apiPackage).replace(".", "/"), "JavaRestResourceUtil.java"));

writeOptional(outputFolder, new SupportingFile("bootstrap.mustache", (implFolder + '/' + apiPackage).replace(".", "/"), "Bootstrap.java"));

writeOptional(outputFolder, new SupportingFile("web.mustache", ("src/main/webapp/WEB-INF"), "web.xml"));
writeOptional(outputFolder, new SupportingFile("index.mustache", ("src/main/webapp"), "index.html"));

writeOptional(outputFolder, new SupportingFile("log4j.mustache", ("conf"), "log4j.properties"));

writeOptional(outputFolder, new SupportingFile("logback.mustache", ("src/main/resources"), "logback.xml"));

if ( additionalProperties.containsKey("dateLibrary") ) {
setDateLibrary(additionalProperties.get("dateLibrary").toString());
additionalProperties.put(dateLibrary, "true");
}

if ( "joda".equals(dateLibrary) ) {
supportingFiles.add(new SupportingFile("JodaDateTimeProvider.mustache", (sourceFolder + '/' + apiPackage).replace(".", "/"), "JodaDateTimeProvider.java"));
supportingFiles.add(new SupportingFile("JodaLocalDateProvider.mustache", (sourceFolder + '/' + apiPackage).replace(".", "/"), "JodaLocalDateProvider.java"));
} else if ( "java8".equals(dateLibrary) ) {
supportingFiles.add(new SupportingFile("LocalDateTimeProvider.mustache", (sourceFolder + '/' + apiPackage).replace(".", "/"), "LocalDateTimeProvider.java"));
supportingFiles.add(new SupportingFile("LocalDateProvider.mustache", (sourceFolder + '/' + apiPackage).replace(".", "/"), "LocalDateProvider.java"));
}
}

@Override
public void addOperationToGroup(String tag, String resourcePath, Operation operation, CodegenOperation co, Map<String, List<CodegenOperation>> operations) {
String basePath = resourcePath;
if (basePath.startsWith("/")) {
basePath = basePath.substring(1);
}
int pos = basePath.indexOf("/");
if (pos > 0) {
basePath = basePath.substring(0, pos);
}

if (basePath == "") {
basePath = "default";
} else {
if (co.path.startsWith("/" + basePath)) {
co.path = co.path.substring(("/" + basePath).length());
}
co.subresourceOperation = !co.path.isEmpty();
}
List<CodegenOperation> opList = operations.get(basePath);
if (opList == null) {
opList = new ArrayList<CodegenOperation>();
operations.put(basePath, opList);
}
opList.add(co);
co.baseName = basePath;
}

public void hideGenerationTimestamp(boolean hideGenerationTimestamp) {
this.hideGenerationTimestamp = hideGenerationTimestamp;
}

}

提前感谢您的帮助!

最佳答案

这就是 java 加载类的方式,特别是使用 SPI(服务提供者接口(interface))。

这里有文档:

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

问题是您需要指定您的库和 codegen jar,并告诉它要运行哪个类。例如:

# 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

这会将 codegen 库添加到类路径,您的自定义模板库,执行主函数 (io.swagger.codegen.SwaggerCodegen),并将您的类作为目标传递..
