Question

我正在尝试使用摇摇欲坠的代码生成器（版本2.3.1）创建我的第一个自定义代码生成器。我的问题是，我似乎无法访问模型的“变量”。我使用petstore.json示例作为输入，并使用了swagger-codegen-maven-plugin创建生成的源。

在我的胡子模板中，我尝试访问model properties。这适用于“ className”或“ package”之类的属性，但是我无法访问列表类型属性“ vars”。使用“ -DdebugModels”运行时，将显示var，并且还将“ hasVars”报告为true。但是在生成的代码中未使用var，并且“ hasVars”似乎是错误的。我已经简化了模板以在此处显示。首先是模板：

package {{package}};
{{classname}}
{{#vars}}
{{{datatype}}} {{name}} = {{{defaultValue}}}
{{/vars}}
{{#hasVars}}
hasVars
{{/hasVars}}
{{^hasVars}}
has No Vars
{{/hasVars}}

这是Pet的输出示例：

package com.dukescripd.demo.model;
Pet
has No Vars

我从stubs generated by codegen开始了我的项目。这会生成一些小胡子模板，其中包括一个用于api的模板。此模板使用“操作”列表类型属性，效果很好。

这是我的CodeGenerator：

package com.dukescript.swagger.codegen;

import io.swagger.codegen.*;

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

public class DukescriptswaggercodegenGenerator extends DefaultCodegen implements CodegenConfig {

    protected String sourceFolder = "src";
    protected String apiVersion = "1.0.0";

    public CodegenType getTag() {
        return CodegenType.CLIENT;
    }

    public String getName() {
        return "DukeScriptSwaggerCodegen";
    }

    public String getHelp() {
        return "Generates a DukeScript @Model client library.";
    }

    public DukescriptswaggercodegenGenerator() {
        super();

        outputFolder = "generated-code/DukeScriptSwaggerCodegen";

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


        apiTemplateFiles.put(
                "api.mustache", 
                ".java");       

        templateDir = "DukeScriptSwaggerCodegen";

        apiPackage = "io.swagger.client.api";

        modelPackage = "io.swagger.client.model";

        reservedWords = new HashSet<String>(
        );

        additionalProperties.put("apiVersion", apiVersion);

        languageSpecificPrimitives = new HashSet<String>(

        );
    }

    @Override
    public String escapeReservedWord(String name) {
        return "_" + name;  // add an underscore to the name
    }

    public String modelFileFolder() {
        return outputFolder + "/" + sourceFolder + "/" + modelPackage().replace('.', File.separatorChar);
    }

    @Override
    public String apiFileFolder() {
        return outputFolder + "/" + sourceFolder + "/" + apiPackage().replace('.', File.separatorChar);
    }

}

最后是codegen-maven-plugin的配置：

Answer 1

在您的模型中，添加

{{#models}}
{{#model}}

   ...

{{/model}}
{{/models}}

包含{{#vars}}的代码段。

Example
