前言
随着企业数字化转型的需求日益增长，低代码平台作为一种快速开发和部署业务应用的方法，正在获得更多关注。领域驱动设计（DDD）是一种软件架构风格，旨在更好地满足复杂业务需求。结合这两者可以创建灵活且可维护的应用程序。
在本应用中，我们将利用低代码平台的灵活性和DDD的架构优势来构建一个可持续的解决方案。
本文将以一个最常见的实例来展开分析。
一，模型构建
模型构建，主要是根据数据库表，将结构化数据关系（1:1，1:N，N:N）对应完成ormaping映射。实例中采用使用了一个单表模型做演示。同时将在资源库这一层抽象出的接口信息，通过注解完成在DDD领域模型中的注册，使得持久层的操作可见可用。具体的操作办法如下：
（1）进入资源库管理：
资源库是领域模型仓储库的一个具体事项方式，主要管理数据库资源以及已经完成映射的，DAO类库以及其相应的接口操作库。
（2）添加库表资源
完成数据连接导入后可以动态获取库表及业务视图，完成库表导入后由资源库完成相应的代码构建工作。
（3）开始构建
代码构建主要是基于已经建立的持久化模型，根据模版管理库构建对应的代码结构。
添加图片注释，不超过 140 字（可选）
（4）查看构建结果（代码）
完成构建后就可以在线查看生成代码了。
（5）编译代码
完成代码构建后，可以自动或手工完成相关的代码编译工作，编译完成后相应类库信息会同步到领域模型库中，方便领域模型根据模版构建相应的聚合应用体系。
（6）代码示例
相关代码示例如下：

}二，应用聚合
聚合应用是领域模型建模中最为重要的一个环节，这个环节的重点是将，资源库相应的操作接口转换为领域模型应用，通过web聚合器输出位web 引用发布，同时将实体操作转换为领域事件供DDD内部完成调度处理。而聚合应用则是将视图与模型有机结合实现聚合实体以及聚合根应用。同时抽取相应的数据字典以及应用域作为上层的支撑。
（1）导入资源库接口转换为通用聚合实体
（2）查看调整聚合实体配置
（3）查看调整聚合实体代码结构
（4）聚合实体配置
（5）领域事件
（6）实现代码

@ResponseBody

}三，视图修饰
（1）视图结构
视图域是在完成初步聚合实体建模后，根据具体的模型来构建视图体系，这些体系中根据实体的结构来构建视图的结构，最终通过，代码的方式展现处理。
视图模版种类：
视图模版具体化后工程结构：
（2）视图配置
（3）视图修饰
为列表增加菜单
为列表增加分页栏
为表单字段子域配置
配置 模块编译输出
添加图片注释，不超过 140 字（可选）
（4）列表视图源码
