基于vs插件的abp代码生成器

  工作了这么多年,一直都在小公司摸爬滚打,对于小公司而言,开发人员少,代码风格五花八门。要想用更少的人,更快的速度,开发更规范的代码,那自然离不开代码生成器。之前用过动软的,也用过T4,后面又接触了力软。相较而言,力软的代码生成做的体验还是很不错的(不是给他打广告哈)。最近在看abp,发现要按他的规范来开发的话,工作量还是蛮大的,所以他们官方也开发了配套的代码生成器,不过都要收费。国内这块好像做的好点的就52abp了,还有个Magicodes.Admin。前者是类似于官方的做成了vs插件,还比较好用,后者是线上的,据说是生成后可以同步到git仓库,咱也没用过,所以也不清楚好不好用。前段时间稍微空闲点,就参考Magicodes.Admin和52abp搭了个框子,顺便也研究了下基于vs插件的代码生成器,abp的代码生成器也可以做成力软那样的,只不过需要用户先update-database数据库而已,代码生成部分原理都差不多,这里就不提了,这里主要是记录下vs插件开发代码生成器的过程。

 

先上下框子截图:

 

开发过程:

新建VS插件项目

1、新建项目

这里我们要新建VSIX Project

2、建好项目后,右键添加新建项,这里我们选Custom Command

添加好了后,我们修改Command1Package.vsct这个文件:

这里改的是菜单显示的文字,然后我们可以F5运行起来瞧瞧。F5运行后,会另外开启一个vs,如下图:

默认的菜单会被添加到“工具”这个菜单栏中,如下图:

咱们要做代码生成器,肯定不是希望把菜单加在这里的,那要怎么改呢?  还是刚才那个文件,具体位置在:

    <Groups>
      <Group guid="guidCommand1PackageCmdSet" id="MyMenuGroup" priority="0x0600">
        <Parent guid="guidSHLMainMenu" id="IDM_VS_MENU_TOOLS"/>
      </Group>
    </Groups>

关于这个id,几个常用的有下面几个:

IDM_VS_CTXT_SOLNNODE  是指的解决方案资源管理器里的解决方案

IDM_VS_CTXT_SOLNFOLDER    是指的解决方案资源管理器里的 解决方案里的文件夹,不是项目里的哈,这个文件夹是虚拟的,没有实际的文件夹映射

IDM_VS_CTXT_PROJNODE  是指的解决方案资源管理器里的项目

IDM_VS_CTXT_FOLDERNODE  是指的解决方案资源管理器里的项目里的文件夹

IDM_VS_CTXT_ITEMNODE  是指的解决方案资源管理器里的项目里的项,就例如cs、js文件

我们这里要用的就是"IDM_VS_CTXT_ITEMNODE",改完后我们再F5运行下,这个时候我们要打开一个项目了。右键点击瞧瞧(上面那个abp代码生成器是我之前做的,忽略哈):

好了,要的就是这个效果,接下来就要开始做代码生成的了。

 

代码生成

代码生成主要分为三个步骤,1、获取所选文件以及当前项目基本信息。2、生成后端代码。3、生成前端代码

1、获取所选文件以及当前项目基本信息

做VS插件,离不了DTE2这个类,具体的可参考:https://docs.microsoft.com/en-us/dotnet/api/envdte._dte?view=visualstudiosdk-2017

 首先我们要获取DTE2实例,我们打开Command1Package.cs这个类修改初始化方法:

protected override async Task InitializeAsync(CancellationToken cancellationToken, IProgress<ServiceProgressData> progress)
        {
            // When initialized asynchronously, the current thread may be a background thread at this point.
            // Do any initialization that requires the UI thread after switching to the UI thread.
            await this.JoinableTaskFactory.SwitchToMainThreadAsync(cancellationToken);

            DTE2 _dte = await GetServiceAsync(typeof(DTE)) as DTE2;
            await AbpCustomCommand.InitializeAsync(this, _dte);
        }

同时修改Command1.cs的初始化方法:

        public static DTE2 _dte;
        /// <summary>
        /// Initializes the singleton instance of the command.
        /// </summary>
        /// <param name="package">Owner package, not null.</param>
        public static async Task InitializeAsync(AsyncPackage package, DTE2 dte)
        {
            _dte = dte;
            // Switch to the main thread - the call to AddCommand in Command1's constructor requires
            // the UI thread.
            await ThreadHelper.JoinableTaskFactory.SwitchToMainThreadAsync(package.DisposalToken);
            
            OleMenuCommandService commandService = await package.GetServiceAsync((typeof(IMenuCommandService))) as OleMenuCommandService;
            Instance = new Command1(package, commandService);
        }

获取到了DTE2实例了,我们就可以开始获取我们要的基本信息了,我们在Command1.cs类的Execute方法中加入下面代码(注释写的都比较清楚,就不多写了):

#region 获取出基础信息
                    //获取当前点击的类所在的项目
                    Project topProject = selectProjectItem.ContainingProject;
                    //当前类在当前项目中的目录结构
                    string dirPath = GetSelectFileDirPath(topProject, selectProjectItem);

                    //当前类命名空间
                    string namespaceStr = selectProjectItem.FileCodeModel.CodeElements.OfType<CodeNamespace>().First().FullName;
                    //当前项目根命名空间
                    string applicationStr = "";
                    if (!string.IsNullOrEmpty(namespaceStr))
                    {
                        applicationStr = namespaceStr.Substring(0, namespaceStr.IndexOf("."));
                    }
                    //当前类
                    CodeClass codeClass = GetClass(selectProjectItem.FileCodeModel.CodeElements);
                    //当前项目类名
                    string className = codeClass.Name;
                    //当前类中文名 [Display(Name = "供应商")]
                    string classCnName = "";
                    //当前类说明 [Description("品牌信息")]
                    string classDescription = "";
                    //获取类的中文名称和说明
                    foreach (CodeAttribute classAttribute in codeClass.Attributes)
                    {
                        switch (classAttribute.Name)
                        {
                            case "Display":
                                if (!string.IsNullOrEmpty(classAttribute.Value))
                                {
                                    string displayStr = classAttribute.Value.Trim();
                                    foreach (var displayValueStr in displayStr.Split(','))
                                    {
                                        if (!string.IsNullOrEmpty(displayValueStr))
                                        {
                                            if (displayValueStr.Split('=')[0].Trim() == "Name")
                                            {
                                                classCnName = displayValueStr.Split('=')[1].Trim().Replace("\"", "");
                                            }
                                        }
                                    }
                                }
                                break;
                            case "Description":
                                classDescription = classAttribute.Value;
                                break;
                        }
                    }

                    //获取当前解决方案里面的项目列表
                    List<ProjectItem> solutionProjectItems = GetSolutionProjects(_dte.Solution);

 2、生成后端代码

具体代码生成这里用到了razor引擎,我们先配置razor引擎:

        private void InitRazorEngine()
        {
            var config = new TemplateServiceConfiguration
            {
                TemplateManager = new EmbeddedResourceTemplateManager(typeof(Template))
            };
            Engine.Razor = RazorEngineService.Create(config);
        }

然后在Command1.cs的构造函数里面初始化razor引擎。接着按照我们需要的项目结构来构建生成流程,具体如下:

                    //1.同级目录添加 Authorization 文件夹
                    //2.往新增的 Authorization 文件夹中添加 xxxPermissions.cs 文件 
                    //3.往新增的 Authorization 文件夹中添加 xxxAuthorizationProvider.cs 文件
                    //4.往当前项目根目录下文件夹 Authorization 里面的AppAuthorizationProvider.cs类中的SetPermissions方法最后加入 SetxxxPermissions(pages); 
                    //5.往xxxxx.Application项目中增加当前所选文件所在的文件夹
                    //6.往第五步新增的文件夹中增加Dto目录
                    //7.往第六步新增的Dto中增加CreateOrUpdatexxxInput.cs  xxxEditDto.cs  xxxListDto.cs  GetxxxForEditOutput.cs  GetxxxsInput.cs这五个文件
                    //8.编辑CustomDtoMapper.cs,添加映射
                    //9.往第五步新增的文件夹中增加 xxxAppService.cs和IxxxAppService.cs 类
                    //10.编辑DbContext

用razor引擎,自然少不了模板,这里就贴一个模板出来,其他的兄弟们自己查看源码哈:

                await Update@(Model.Name)Async(input);
            }
        }

        /// <summary>
        /// 新建
        /// </summary>
        /// <param name="input"></param>
        /// <returns></returns>
        [AbpAuthorize(@(Model.Name)Permissions.Create)]
        public async Task<@(Model.Name)ListDto> Create@(Model.Name)Async(CreateOrUpdate@(Model.Name)Input input)
        {
            var entity = input.@(Model.Name).MapTo<@(Model.Name)>();
            return (await _repository.InsertAsync(entity)).MapTo<@(Model.Name)ListDto>();
        }

        /// <summary>
        /// 编辑
        /// </summary>
        /// <param name="input"></param>
        /// <returns></returns>
        [AbpAuthorize(@(Model.Name)Permissions.Edit)]
        public async Task<@(Model.Name)ListDto> Update@(Model.Name)Async(CreateOrUpdate@(Model.Name)Input input)
        {
            var entity = input.@(Model.Name).MapTo<@(Model.Name)>();
            return (await _repository.UpdateAsync(entity)).MapTo<@(Model.Name)ListDto>();
        }

        /// <summary>
        /// 删除@(Model.CnName)
        /// </summary>
        [AbpAuthorize(@(Model.Name)Permissions.Delete)]
        public async Task Delete(EntityDto<long> input)
        {
            await _repository.DeleteAsync(input.Id);
        }

        /// <summary>
        /// 批量删除@(Model.CnName)
        /// </summary>
        [AbpAuthorize(@(Model.Name)Permissions.BatchDelete)]
        public async Task BatchDelete(List<long> input)
        {
            await _repository.DeleteAsync(a => input.Contains(a.Id));
        }
    }
}

接着我们开始生成,基本方法都差不多,我们贴一个新建和编辑的代码瞧瞧:

新建:

        /// <summary>
        /// 创建Permissions权限常量类
        /// </summary>
        /// <param name="applicationStr">根命名空间</param>
        /// <param name="name">类名</param>
        /// <param name="authorizationFolder">父文件夹</param>
        private void CreatePermissionFile(string applicationStr, string name, ProjectItem authorizationFolder)
        {
            var model = new PermissionsFileModel() { Namespace = applicationStr, Name = name };
            string content = Engine.Razor.RunCompile("PermissionsTemplate", typeof(PermissionsFileModel), model);
            string fileName = $"{name}Permissions.cs";
            AddFileToProjectItem(authorizationFolder, content, fileName);
        }

编辑:

/// <summary>
        /// 添加权限
        /// </summary>
        /// <param name="topProject"></param>
        /// <param name="className"></param>
        private void SetPermission(Project topProject, string className)
        {
            ProjectItem AppAuthorizationProviderProjectItem = _dte.Solution.FindProjectItem(topProject.FileName.Substring(0, topProject.FileName.LastIndexOf("\\")) + "\\Authorization\\AppAuthorizationProvider.cs");
            if (AppAuthorizationProviderProjectItem != null)
            {
                CodeClass codeClass = GetClass(AppAuthorizationProviderProjectItem.FileCodeModel.CodeElements);
                var codeChilds = codeClass.Members;
                foreach (CodeElement codeChild in codeChilds)
                {
                    if (codeChild.Kind == vsCMElement.vsCMElementFunction && codeChild.Name == "SetPermissions")
                    {
                        var insertCode = codeChild.GetEndPoint(vsCMPart.vsCMPartBody).CreateEditPoint();
                        insertCode.Insert("            Set" + className + "Permissions(pages);\r\n");
                        insertCode.Insert("\r\n");
                    }
                }
                AppAuthorizationProviderProjectItem.Save();
            }
        }

其他的都自己查看源码哈

 

3、生成前端代码

前端生成流程如下:

//1 往app\\admin文件夹下面加xxx文件夹
//2 往新增的文件夹加xxx.component.html   xxx.component.ts   create-or-edit-xxx-modal.component.html  create-or-edit-xxx-modal.component.ts这4个文件
//3 修改app\\admin\\admin.module.ts文件,  import新增的组件   注入组件
//4 修改app\\admin\\admin-routing.module.ts文件   添加路由
//5 修改 app\\shared\\layout\\nav\\app-navigation.service.ts文件   添加菜单
//6 修改 shared\\service-proxies\\service-proxy.module.ts文件  提供服务

前端和后端的生成大部分都差不多,不过修改的因为咱们这是针对vs的插件,所以没法编辑vscode里的文件,这里我用了笨办法,对应要改的文件中加了特殊标识,类似于 // {#insert import code#},然后生成了代码文件后,我们替换掉标识符,贴段代码出来:

        /// <summary>
        /// 注入服务
        /// </summary>
        /// <param name="frontPath"></param>
        /// <param name="name"></param>
        private void AddProxy(string frontPath, string name)
        {
            string routesCode = "ApiServiceProxies."+ name + "ServiceProxy,\r\n";
            routesCode += "        // {#insert routes code#}\r\n";

            string proxyFilePath = frontPath + "shared\\service-proxies\\service-proxy.module.ts";
            string proxyContent = File.ReadAllText(proxyFilePath);
            proxyContent = proxyContent.Replace("// {#insert proxy code#}", routesCode);

            AddFileToDirectory(proxyFilePath, proxyContent);
        }

 

至此,代码生成器基本功能就算是OK了,不过要达到完善水平,要做的事情还很多,这里列出几点:

1、代码封装

2、生成进度条

3、异步提升生成效率

4、添加交互界面

5、根据实体类的字段类型生成对应的前端控件

6、还没想好。。。

 

至于框子,要做的就更多了,现在就只是弄了个基本的,后面还考虑下面几点:

1、完善文章模块

2、文件存储模块(本地,七牛云,阿里云)

3、消息模块

4、短信模块

5、微信模块

6、还没想好。。。

这个项目最后的愿景的能基于这个框子做几套基础的开源应用出来,比如基础的商城、ERP、CRM等,DOTNET领域基础开源应用太少了,2019年再不努力点,DOTNET后面的路就更难了,市场都没有了,咱们在技术圈里自Hi也没什么意义了,大家一起加油吧。

最近家里有些事情需要在家办公,各位有要兼职的或者有项目的可以聊聊哇
