CodeSmith再重温
很早有个项目Mybatis用了codeS制成模板,当时就是应用,没啥想法、又有一个项目也是CodeSmith做的,模板很复杂,就更无兴致了、也许永远用不到,可是随着生产环境的变化、客户项目的业务不同、略发现挺有意思的:
CodeSmith 8.0:

<%@ CodeTemplate Inherits="CodeTemplate" Language="C#" TargetLanguage="Text" Description="NetTiers main template." Debug="True" ResponseEncoding="UTF-8"%> <%-- 注册实体层Entity模板 --%> <%@ Register Name="EntityTemplate" Template="Entity.cst" MergeProperties="Flase" ExcludeProperties=""%> <%-- 数据库 --%> <%@ Property Name="SourceDatabase" Type="SchemaExplorer.DatabaseSchema" DeepLoad="True" Optional="False" Category="01.

<%@ CodeTemplate Inherits="CodeTemplate" Language="C#" TargetLanguage="Text" Description="NetTiers main template." Debug="True" ResponseEncoding="UTF-8"%> <%@ Assembly Name="SchemaExplorer"%> <%@ Import Namespace="SchemaExplorer"%> <%@ Property Name="Table" Type="TableSchema" DeepLoad="True" Optional="False" Category="01. Getting Started - Required" Description="Database that the tables views, and stored procedures should be based on. IMPORTANT!!! If SourceTables and SourceViews are left blank, the Entire Database will then be generated."%> using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Entity { public partial class <%= Table.Name%> { <%foreach(ColumnSchema col in Table.Columns){ %> public <%= col.DataType %> <%= col.Name %> { get ; set ; } <% } %> } }
两段代码,一份是配置文档、一个是模板、用C#语言写,读起来不是很难,目标是根据数据库各个表字段,生成model表。
CodeSmith连接数据库,获取数据库的结构,如各个表的名称,表的字段,表间的关系等等,再根据用户自定义好的模板文件,用数据库结构中的关键字替代模板的动态变量,最终输出并保存为我们需要的目标文件。
