ABP 结合 MongoDB 集成依赖注入

1.我们再ABP项目添加一个.NET Core类库  类库名自定定义， 我这里定义为 TexHong_EMWX.MongoDb

添加NuGet包。

ABP

mongocsharpdriver

 

 

添加 AbpMongoDbConfigurationExtensions.cs

 /// 

    /// 定义扩展方法  允许配置ABP MongoDB模块
    /// 
    public static class AbpMongoDbConfigurationExtensions
    {
        /// 

        /// 用于配置ABP MongoDB模块。
        /// 
        public static IAbpMongoDbModuleConfiguration AbpMongoDb(this IModuleConfigurations configurations)
        {
            return configurations.AbpConfiguration.Get();
        }
    }

添加 AbpMongoDbModuleConfiguration.cs

 internal class AbpMongoDbModuleConfiguration : IAbpMongoDbModuleConfiguration
    {
        public string ConnectionString { get; set; }

        public string DatabaseName { get; set; }
    }

添加  IAbpMongoDbModuleConfiguration

  public interface IAbpMongoDbModuleConfiguration
    {
        string ConnectionString { get; set; }

        string DatabaseName { get; set; }
    }

 

添加 MongoDbRepositoryBase.cs

/// 

    /// Implements IRepository for MongoDB.
    /// 
    /// Type of the Entity for this repository
    public class MongoDbRepositoryBase : MongoDbRepositoryBaseint>, IRepository
        where TEntity : class, IEntity<int>
    {
        public MongoDbRepositoryBase(IMongoDatabaseProvider databaseProvider)
            : base(databaseProvider)
        {
        }
    }
    /// 

    /// Implements IRepository for MongoDB.
    /// 
    /// Type of the Entity for this repository
    /// Primary key of the entity
    public class MongoDbRepositoryBase : AbpRepositoryBase
        where TEntity : class, IEntity
    {
        public virtual MongoDatabase Database
        {
            get { return _databaseProvider.Database; }
        }
        public virtual MongoCollection Collection
        {
            get
            {
                return _databaseProvider.Database.GetCollection(typeof(TEntity).Name);
            }
        }
        private readonly IMongoDatabaseProvider _databaseProvider;
        public MongoDbRepositoryBase(IMongoDatabaseProvider databaseProvider)
        {
            _databaseProvider = databaseProvider;
        }

        public override IQueryable GetAll()
        {
            return Collection.AsQueryable();
        }

        public override TEntity Get(TPrimaryKey id)
        {
            var query = MongoDB.Driver.Builders.Query.EQ(e => e.Id, id);
            var entity = Collection.FindOne(query);
            if (entity == null)
            {
                throw new EntityNotFoundException("There is no such an entity with given primary key. Entity type: " + typeof(TEntity).FullName + ", primary key: " + id);
            }
            return entity;
        }
        public override TEntity FirstOrDefault(TPrimaryKey id)
        {
            var query = MongoDB.Driver.Builders.Query.EQ(e => e.Id, id);
            return Collection.FindOne(query);
        }
        public override TEntity Insert(TEntity entity)
        {
            Collection.Insert(entity);
            return entity;
        }
        public override TEntity Update(TEntity entity)
        {
            Collection.Save(entity);
            return entity;
        }
        public override void Delete(TEntity entity)
        {
            Delete(entity.Id);
        }
        public override void Delete(TPrimaryKey id)
        {
            var query = MongoDB.Driver.Builders.Query.EQ(e => e.Id, id);
            Collection.Remove(query);
        }
    }

添加 MongoDbUnitOfWork.cs 

/// 

    /// Implements Unit of work for MongoDB.
    /// 
    public class MongoDbUnitOfWork : UnitOfWorkBase, ITransientDependency
    {
        /// 

        /// Gets a reference to MongoDB Database.
        /// 
        public MongoDatabase Database { get; private set; }

        private readonly IAbpMongoDbModuleConfiguration _configuration;

        /// 

        /// Constructor.
        /// 
        public MongoDbUnitOfWork(
            IAbpMongoDbModuleConfiguration configuration,
            IConnectionStringResolver connectionStringResolver,
            IUnitOfWorkFilterExecuter filterExecuter,
            IUnitOfWorkDefaultOptions defaultOptions)
            : base(
                  connectionStringResolver,
                  defaultOptions,
                  filterExecuter)
        {
            _configuration = configuration;
            BeginUow();
        }

#pragma warning disable
        protected override void BeginUow()
        {
            //TODO: MongoClientExtensions.GetServer(MongoClient)' is obsolete: 'Use the new API instead.
            Database = new MongoClient(_configuration.ConnectionString)
                .GetServer()
                .GetDatabase(_configuration.DatabaseName);
        }
#pragma warning restore

        public override void SaveChanges()
        {

        }

#pragma warning disable 1998
        public override async Task SaveChangesAsync()
        {

        }
#pragma warning restore 1998

        protected override void CompleteUow()
        {

        }

#pragma warning disable 1998
        protected override async Task CompleteUowAsync()
        {

        }
#pragma warning restore 1998
        protected override void DisposeUow()
        {

        }
    }

添加  UnitOfWorkMongoDatabaseProvider.cs

/// 

    /// Implements  that gets database from active unit of work.
    /// 
    public class UnitOfWorkMongoDatabaseProvider : IMongoDatabaseProvider, ITransientDependency
    {
        public MongoDatabase Database { get { return _mongoDbUnitOfWork.Database; } }

        private readonly MongoDbUnitOfWork _mongoDbUnitOfWork;

        public UnitOfWorkMongoDatabaseProvider(MongoDbUnitOfWork mongoDbUnitOfWork)
        {
            _mongoDbUnitOfWork = mongoDbUnitOfWork;
        }
    }

添加 IMongoDatabaseProvider.cs

public interface IMongoDatabaseProvider
    {
        /// 

        /// Gets the .
        /// 
        MongoDatabase Database { get; }
    }

添加 TexHong_EMWXMongoDBModule.cs

  

/// 

    /// This module is used to implement "Data Access Layer" in MongoDB.
    /// 
    [DependsOn(typeof(AbpKernelModule))]
    public class TexHong_EMWXMongoDBModule : AbpModule
    {
        public override void PreInitialize()
        {
            IocManager.Register();            
            // 配置 MonggoDb 数据库地址与名称
            IAbpMongoDbModuleConfiguration abpMongoDbModuleConfiguration = Configuration.Modules.AbpMongoDb();
            abpMongoDbModuleConfiguration.ConnectionString = "mongodb://admin:[email protected]:27017/texhong_em";
            abpMongoDbModuleConfiguration.DatabaseName = "texhong_em";
        }

        public override void Initialize()
        {
            IocManager.RegisterAssemblyByConvention(typeof(TexHong_EMWXMongoDBModule).GetAssembly());            
            IocManager.Registerlong>>();
        }
    }

最后项目的架构

 

 

 

添加单元测试  MongoDbAppService_Tests.cs 

 public class MongoDbAppService : TexHong_EMWXTestBase
    {
        private readonly MongoDbRepositoryBaselong> _mongoDbUserRepositoryBase;
        
        public MongoDbAppService()
        {
           this._mongoDbUserRepositoryBase = Resolvelong>>();
        }
        [Fact]
        public async Task CreateUsers_Test()
        {
            long Id = (DateTime.Now.Ticks - 621356256000000000) / 10000;            
            await _mongoDbUserRepositoryBase.InsertAndGetIdAsync(new User() { Id= Id, Name = "123", EmailConfirmationCode = "1111", UserName = "2222" });
            User user = _mongoDbUserRepositoryBase.Get(Id);
        }        
    }

注意单元测试要引用 MongoDb项目。

同时在TestModule.cs属性依赖 DependsOn 把Mongodb 的 Module添加进去，不然会导致运行失败无法注入。
