西宁建设公司网站,wordpress只有我可以看,百度网站优化 件,wordpress 初始化 数据库连接整个解决方案按照分层思想来划分不同功能模块#xff0c;以提供User服务的Api为需求#xff0c;各个层次的具体实现如下所示#xff1a; 1、新建数据库User表 数据库使用SQLExpress版本#xff0c;表的定义如下所示#xff1a; CREATE TABLE [dbo].[User] ([Id] …整个解决方案按照分层思想来划分不同功能模块以提供User服务的Api为需求各个层次的具体实现如下所示 1、新建数据库User表 数据库使用SQLExpress版本表的定义如下所示 CREATE TABLE [dbo].[User] ([Id] INT IDENTITY (1, 1) NOT NULL,[Name] NVARCHAR (50) NOT NULL,[Password] NVARCHAR (50) NOT NULL,[Age] INT NOT NULL,[Birthdate] DATE NOT NULL,[CreateTime] DATETIME DEFAULT (getdate()) NOT NULL,[CreateUserId] NVARCHAR (50) NOT NULL,[CreateUserName] NVARCHAR (50) NOT NULL,[ModifiedTime] DATETIME NULL,[ModifiedUserId] NVARCHAR (50) NULL,[ModifiedUserName] NVARCHAR (50) NULL,PRIMARY KEY CLUSTERED ([Id] ASC) ); 2、实体层 新建类库类型的项目.net framework框架版本4.5User实体类如下 public class User{public int Id { get; set; }public string Name { get; set; }public string Password { get; set; }public int Age { get; set; }public DateTime Birthdate { get; set; }public DateTime CreateTime { get; set; }public string CreateUserId { get; set; }public string CreateUserName { get; set; }public DateTime? ModifiedTime { get; set; }public string ModifiedUserId { get; set; }public string ModifiedUserName { get; set; }} 3、数据库层 该层提供数据库接口操作采用EntitFramework4.4.0.0作为ORM实体映射框架 定义数据库操作接口IRepository public interface IRepositoryTEntity : IDisposable where TEntity : class{IEnumerableTEntity Get();IEnumerableTEntity Get(ExpressionFuncTEntity, bool filter);IEnumerableTEntity GetTOderKey(ExpressionFuncTEntity, bool filter, int pageIndex, int pageSize, ExpressionFuncTEntity, TOderKey sortKeySelector, bool isAsc true);int Count(ExpressionFuncTEntity, bool predicate);void Update(TEntity instance);void Add(TEntity instance);void Delete(TEntity instance);} 定义数据库上下文类BceDbContext public class BceDbContext:DbContext{public BceDbContext():base(DaLeiDB){Database.SetInitializerAceDbContext(null);}public DbSetUser Users { get; set; }protected override void OnModelCreating(DbModelBuilder modelBuilder){modelBuilder.EntityUser().ToTable(User);base.OnModelCreating(modelBuilder);}} 定义数据库通用操作实现类BceRepository public class BceRepositoryTEntity : IRepositoryTEntity where TEntity : class{public BceDbContext DbContext { get; private set; }public DbSetTEntity DbSet { get; private set; }public BceRepository(BceDbContext context){Guard.ArgumentNotNull(context, context);this.DbContext context;this.DbSet this.DbContext.SetTEntity();}public IEnumerableTEntity Get(){return this.DbSet.AsQueryable();}public IEnumerableTEntity Get(ExpressionFuncTEntity, bool filter){return this.DbSet.Where(filter).AsQueryable();}public IEnumerableTEntity GetTKey(ExpressionFuncTEntity, bool filter, int pageIndex, int pageSize, ExpressionFuncTEntity, TKey sortKeySelector, bool isAsc true){Guard.ArgumentNotNull(filter, predicate);Guard.ArgumentNotNull(sortKeySelector, sortKeySelector);if (isAsc){return this.DbSet.Where(filter).OrderBy(sortKeySelector).Skip(pageSize * (pageIndex - 1)).Take(pageSize).AsQueryable();}else{return this.DbSet.Where(filter).OrderByDescending(sortKeySelector).Skip(pageSize * (pageIndex - 1)).Take(pageSize).AsQueryable();}}public int Count(ExpressionFuncTEntity, bool predicate){return this.DbSet.Where(predicate).Count();}public void Add(TEntity instance){Guard.ArgumentNotNull(instance, instance);this.DbSet.Attach(instance);this.DbContext.Entry(instance).State EntityState.Added;this.DbContext.SaveChanges();}public void Update(TEntity instance){Guard.ArgumentNotNull(instance, instance);this.DbSet.Attach(instance);this.DbContext.Entry(instance).State EntityState.Modified;this.DbContext.SaveChanges();}public void Delete(TEntity instance){Guard.ArgumentNotNull(instance, instance);this.DbSet.Attach(instance);this.DbContext.Entry(instance).State EntityState.Deleted;this.DbContext.SaveChanges();}public void Dispose(){this.DbContext.Dispose();}} 定义用户表数据库操作额外的接口IUserRepository namespace DaLei.Repository {public interface IUserRepository{User FindByName(string name);ListUser FindByAge(int start, int end);} } 定义用户表数据库操作额外的实现类UserRepository namespace DaLei.Repository {public class UserRepository : BceRepositoryUser, IUserRepository{public UserRepository(BceDbContext bceDbContext):base(bceDbContext){}public ListUser FindByAge(int start, int end){var rst this.DbSet.AsQueryable().Where(uu.Agestart u.Ageend).ToList();return rst;}public User FindByName(string name){var rst this.DbSet.AsQueryable().Where(u u.Name name).FirstOrDefault();return rst;}} } 4、服务接口层 定义了对外提供用户服务的接口契约具体如下 namespace DaLei.IService {public interface IUserService{User FindByName(string name);ListUser FindByAge(int start, int end);ListUser GetList();} } 5、服务具体实现层 服务基类实现 using System; using System.Collections.Generic;namespace DaLei.Service {public abstract class ServiceBase : IDisposable{public IListIDisposable DisposableObjects { get; private set; }public ServiceBase(){this.DisposableObjects new ListIDisposable();}protected void AddDisposableObject(object obj){IDisposable disposable obj as IDisposable;if (null ! disposable){this.DisposableObjects.Add(disposable);}}public void Dispose(){foreach (IDisposable obj in this.DisposableObjects){if (null ! obj){obj.Dispose();}}}} } 用户服务接口具体实现 using DaLei.IService; using DaLei.Model; using DaLei.Repository; using System.Collections.Generic;namespace DaLei.Service {public class UserService : ServiceBase,IUserService{private IUserRepository userRepository;public UserService(IUserRepository userRepository){this.userRepository userRepository;this.AddDisposableObject(userRepository);}public ListUser FindByAge(int start, int end){return this.userRepository.FindByAge(start,end);}public User FindByName(string name){return this.userRepository.FindByName(name);}public ListUser GetList(){return this.userRepository.FindByAge(0, 100);}} }6、应用层 新建Asp.net WebApi项目引用服务接口项目、服务实现项目、实体类项目unity相关程序集EntityFramework程序集。 web.config配置连接字符串和unity相关内容 ?xml version1.0 encodingutf-8? !--有关如何配置 ASP.NET 应用程序的详细信息请访问https://go.microsoft.com/fwlink/?LinkId169433 -- configurationconfigSectionssection nameunity typeMicrosoft.Practices.Unity.Configuration.UnityConfigurationSection, Microsoft.Practices.Unity.Configuration //configSectionsunitysectionExtension typeMicrosoft.Practices.Unity.InterceptionExtension.Configuration.InterceptionConfigurationExtension, Microsoft.Practices.Unity.Interception.Configuration /containerscontainerextension typeInterception /register typeDaLei.IService.IUserService, DaLei.IService mapToDaLei.Service.UserService, DaLei.Service /register typeDaLei.Repository.IUserRepository, DaLei.Repository mapToDaLei.Repository.UserRepository, DaLei.Repositoryinterceptor typeInterfaceInterceptor /policyInjection //register/container/containers/unityconnectionStringsadd nameDaLeiDB connectionStringdata source.\SQLEXPRESS;Integrated SecuritySSPI;Initial CatalogDaleiDB;User IDsa;Passwordanpiel0991;
