在小胡子模板中访问 Swagger codegen 模型变量

Question

我正在尝试使用 swagger codegen（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 "vars"。我使用 petstore.json 示例作为输入，并使用 swagger-codegen-maven-plugin 来创建生成的源。

在我的小胡子模板中，我正在尝试访问 model properties。这适用于 "className" 或 "package" 等属性，但我无法访问列表类型属性 "vars"。当运行“-DdebugModels”时，显示变量并且 "hasVars" 被报告为 true。但是在生成的代码中没有使用 vars 并且 "hasVars" 似乎是错误的。我已经简化了我的模板以在此处显示它。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

我用 stubs generated by codegen 开始了我的项目。这会生成一些胡子模板，包括一个用于 api 的模板。此模板使用 "operations" 列表类型属性，效果很好。

这是我的代码生成器：

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

在你的model.mustache中添加

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

   ...

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

代码段周围 {{#vars}}。
