先简单的做一个学习架子，
EF层用的是 EFCore(2.1.0)+ Pomelo.EntityFrameworkCore.MySql(2.1.0)
实体映射主要是用了这三个类:
public interface IEntityTypeConfiguration
{
void Map(ModelBuilder builder);
} public interface IEntityTypeConfiguration<T> : IEntityTypeConfiguration where T : class
{
void Map(EntityTypeBuilder<T> builder);
} public abstract class WGEntityTypeConfig<T> : IEntityTypeConfiguration<T> where T : class
{
public abstract void Map(EntityTypeBuilder<T> builder); public void Map(ModelBuilder builder)
{
Map(builder.Entity<T>());
}
} public static class ModelBuilderExtentcs
{
private static IEnumerable<Type> GetMappingTypes(this Assembly assembly,Type mappingInterface)
{
return assembly.GetTypes().Where(x => !x.GetTypeInfo().IsAbstract && x.GetInterfaces().
Any(y => y.GetTypeInfo().IsGenericType && y.GetGenericTypeDefinition() == mappingInterface));
} public static void AddEntityConfigurationsFromAssembly(this ModelBuilder modelBuilder,Assembly assembly)
{
var mappingTypes = assembly.GetTypes()
.Where(type => type.BaseType != null && type.BaseType.IsGenericType && type.BaseType.GetGenericTypeDefinition() == typeof(WGEntityTypeConfig<>));
//var mappingTypes = assembly.GetMappingTypes(typeof(WGEntityTypeConfig<>));
foreach (var config in mappingTypes.Select(Activator.CreateInstance).Cast<IEntityTypeConfiguration>())
{
config.Map(modelBuilder);
}
}
}
然后在这里
接下来是简单的注入:
项目分成这几层：
BLL,DAL,EF，UI
BLL,DAL 层要实现注入可以加一个接口，IServiceSupportExten
然后
Assembly asmBLL = Assembly.Load(new AssemblyName("BLL"));
var serviceBLLTypes = asmBLL.GetTypes().Where(t => typeof(IServiceSupportExten).IsAssignableFrom(t) && !t.GetTypeInfo().IsAbstract);
foreach (var serviceType in serviceBLLTypes)
{
foreach (var interType in serviceType.GetInterfaces())
{
services.AddSingleton(interType, serviceType);
}
} Assembly asmDAL = Assembly.Load(new AssemblyName("DAL"));
var serviceDALTypes = asmDAL.GetTypes().Where(t => typeof(IServiceSupportExten).IsAssignableFrom(t) && !t.GetTypeInfo().IsAbstract);
foreach (var serviceType in serviceDALTypes)
{
foreach (var interType in serviceType.GetInterfaces())
{
services.AddSingleton(interType, serviceType);
}
}
.net Core 默认提供了一种注入方式，然后，自己也去网上找了代码写了别一种
