【.NET架构】BIM软件架构02：Web管控平台后台架构

一、前言

       之前一篇叙述的是Revit插件（桌面软件）的软件架构，本篇将开始叙述Web项目的架构方案。今年一月在老东家加入BIM平台部门，为一些大型国家项目搭建BIM管控平台，业主使用管控平台可以实时了解各部门的施工状态（包括进度、现场管理、产值等等），将这些信息与WebGL三维模型中的构件相互关联就可以监控整个施工项目。

我们知道，一个Web项目如果使用MVC的方式的话常常使用到ApiController去请求数据，并根据返回的数据进行页面的更新。由于平台项目属于大型项目，所以平台架构师将ApiController/Action函数里的核心业务逻辑抽出，放在另一个解决方案中，即CoreService.sln。Web项目只要引用CoreService里的dlls，并以Unity注入的方式使用即可。为了不会让大家看得太晕，本篇还是以CoreService.sln为主，如何调用的话会写在下一篇中。

二、架构简图

可以看到，整个项目是比较清晰的：

1. DataBase.EFModel就是EntityFramework进行ORM放置edmx系列文件的地方。

2. Common用于放置一些基本的操作函数。

}

3. Infrastructure与Module是一对，Infrastructure用于定义相关接口，而Module用于实现Infrastructure的接口。这也是本文重点介绍的。

三、.Infrastructure与.Core

.Infrastructure

.Infrastructure一般可以有4个文件夹：

1. DatabaseContext主要定义与EF相关的操作接口：

//事务操作
public interface ITransactionProcessor
{
      void BeginTransaction();
      void Commit();
      void Rollback();
}

//CRUD
public interface IRepositoryContext : ITransactionProcessor, IDisposable
{
      void Initialize();
      void Add<T>(T entity) where T : class;
      void Update<T>(T entity) where T : class;
      void Delete<T>(T entity) where T : class;
      void Save();
}

//最后定义EF上下文操作接口
public interface IEFRepositoryContext : IRepositoryContext
{
        DbContext Context { get; }
}

2. DataContracts主要定义一些业务内需要的数据结构，注意其不引用EF中的ORM对象

3. Repositories主要定义EF中ORM对象集合接口

//定义ORM对象数据集合操作泛型接口，T必须为类
public interface IRepository<TEntity> where TEntity : class
{
        /// <summary>
        /// Return IQueryable without actually query DB
        /// </summary>
        /// <param name="expression"></param>
        /// <param name="includePath"></param>
        /// <returns></returns>
        IQueryable<TEntity> Query(Expression<Func<TEntity, bool>> expression = null, params string[] includePath);

        /// <summary>
        /// Find the first object which mataches the expression
        /// </summary>
        /// <param name="expression"></param>
        /// <returns></returns>
        TEntity FirstOrDefault(Expression<Func<TEntity, bool>> expression = null, params string[] includePath);

        /// <summary>
        /// Finds an entity with the given primary key values.
        /// The ordering of composite key values is as defined in the EDM
        /// </summary>
        /// <param name="keyValues"></param>
        /// <returns></returns>
        TEntity FindByKeyValues(params object[] keyValues);

        /// <summary>
        /// 根据指定条件表达式得到数据查询列表
        /// if no expression, resurn all
        /// </summary>
        IList<TEntity> FindList(Expression<Func<TEntity, bool>> expression = null, params string[] includePath);

        IList<TEntity> FindDistinctList(Expression<Func<TEntity, bool>> expression = null, params string[] includePath);

        IList<TEntity> FindListByOrder<TKey>(Expression<Func<TEntity, bool>> expression = null, Expression<Func<TEntity, TKey>> orderBy = null, bool ascending = true, params string[] includePath);

        /// <summary>
        /// Add entity into DB context
        /// </summary>
        /// <param name="entity"></param>
        void Add(TEntity entity);

        /// <summary>
        /// Add a collection of entities
        /// </summary>
        /// <param name="entities"></param>
        void Add(IEnumerable<TEntity> entities);

        /// <summary>
        /// 修改实体
        /// </summary>
        /// <param name="entity">实体</param>
        void Update(TEntity entity);

        /// <summary>
        /// Update a collection of entities
        /// </summary>
        /// <param name="entities"></param>
        void Update(IEnumerable<TEntity> entities);

        /// <summary>
        /// Remove entity by key or keys
        /// </summary>
        /// <param name="keyValues"></param>
        void DeleteByKey(params object[] keyValues);

        /// <summary>
        /// Remove entity
        /// </summary>
        /// <param name="entity"></param>
        void Delete(TEntity entity);

        /// <summary>
        /// Remove a collection of entities
        /// </summary>
        /// <param name="entity"></param>
        void Delete(IEnumerable<TEntity> entities);

        /// <summary>
        /// 分页获取全部集合
        /// </summary>
        /// <param name="count">返回的记录总数</param>
        /// <param name="pageIndex">页码</param>
        /// <param name="pageSize">每页大小</param>
        /// <returns>集合</returns>
        IList<TEntity> LoadPageList<TKey>(out long count, int pageIndex, int pageSize, Expression<Func<TEntity, bool>> expression = null, Expression<Func<TEntity, TKey>> orderBy = null, bool ascending = true, params string[] includePath);

        IList<TEntity> SqlQueryList(string sqlQueryScript, params object[] parameters);
}

//定义一个通过Sql查询脚本与相关参数得到数据集合的接口
public interface IEntityRepository
{
    IEnumerable<object> QueryEntities(string sqlQueryScript, params object[] parameters);
}

4. Service主要定义业务逻辑服务接口

---

.Core

Core项目主要是注册所有接口并且对Infrastructure中定义的接口进行实现。

    public class ApplicationService
    {
        private static object mobjLock = new object();
        private static ApplicationService mobjInstance = new ApplicationService();
        public bool IsInitialized { get; set; }

        public static ApplicationService Instance
        {
            get
            {
                return mobjInstance;
            }
        }

        private ApplicationService()
        {
        }

        public void Initialize()
        {
            lock (mobjLock)
            {
                if (IsInitialized)
                    return;

                // Register all interfaces first
                IUnityContainer container = ServiceLocator.Instance.GetContainer();

                IResourceManagerUtils resourceManager = ServiceLocator.Instance.GetService<IResourceManagerUtils>();
                resourceManager.InitializeResource("Resource", "SharedResources", System.Globalization.CultureInfo.CurrentCulture, "TestResource");

                Assembly[] assemblies = AppDomain.CurrentDomain.GetAssemblies();
                foreach (Assembly assembly in assemblies)
                {
                    // fix bug that GetTypes() of some assembly may throw exception
                    // only allow customized assebmly start with Platform.
                    string assebmlyName = assembly.GetName().Name.ToLower();

                    try
                    {
                        IEnumerable<Type> definedTypes = assembly.GetTypes().Where(t => t.IsClass && !t.IsInterface && !t.IsAbstract);
                        RegisterRepositories(definedTypes);
                    }
                    catch (Exception ex)
                    {
                        ServerLogger.Error(string.Format("Failed to load dll {0}", assebmlyName), ex);
                    }
                }

                IsInitialized = true;
            }
        }

        private void RegisterRepositories(IEnumerable<Type> definedTypes)
        {
            IUnityContainer container = ServiceLocator.Instance.GetContainer();

            Type repositoryInterface = typeof(IRepository<>);
            Type entityRepositoryInterface = typeof(IEntityRepository);

            foreach (Type type in definedTypes)
            {
                Type[] parentIntefaces = type.GetInterfaces();

                // Is IRepository<T>
                if (IsGenericTypeOf(type, repositoryInterface))
                {

                    {
                        ServerLogger.Debug(string.Format("Regsiter type {0} to interface {1}", type.FullName, parentInterface.FullName));
                        container.RegisterType(parentInterface, type);
                    }
                }

                Attribute[] customAttributes = Attribute.GetCustomAttributes(type, false);
                if (customAttributes != null)
                {
                    EntityRepositoryAttribute entityRepositoryAtt = customAttributes.FirstOrDefault(a => a is EntityRepositoryAttribute) as EntityRepositoryAttribute;
                    if (entityRepositoryAtt != null)

                        {
                            // Is IEntityRepository
                            if (parentIntefaces.Any(t => t == entityRepositoryInterface))

四、.Infrastructure.Mn与.Module.Mn

.Infrastructure.Mn

当我们完成.Infrastructure项目之后就可以开始写其它模块了。

.Infrastructure.Mn需要引用.Infrastructure与Database.EFModel项目。

最简单的形式如下：

public interface IModuleOneRepository : IRepository<ModuleOneItem>
{
   //ModuleOneItem为EF的ORM对象！
}

public interface IModuleOneService
{
       void functionOne();
       void functionTwo();
}

---

.Module.Mn

.Module.Mn需要引用.Infrastructure、Database.EFModel以及.Infrastructure.Mn项目

最简单的形式如下：

public class ModuleOneRepository : EFRepository<ModuleOneItem>, IModuleOneRepository
{
    public ModuleOneRepository(): base()
    {
    }
}

using Microsoft.Practices.Unity;

public class ModuleOneService:BaseModuleService, IModuleOneService
{
       [Dependency]
       public IModuleOneRepository moduleOneRepository { get; set; }

       public void functionOne(){}
       public void functionTwo(){}
}

//[Dependency]是Unity依赖注入的属性注入标签

五、结语

本篇主要叙述Web项目所需要引用的CoreService相关项目，有了业务核心底层dlls，剩下的就可以在Web项目中进行使用了。Web项目主要使用.Net MVC模式，在我进入项目组时，MVC框架层进行过多次修改。当我有一次拆分完一个模块的js代码时，我和另一位Tech Leader以及我们的总架构师都意识到需要进一步优化我们的MVC框架。下篇将带来Web项目的MVC架构方案以及我们是如何引用本篇的CoreService相关项目！
