扩展entity framework core 实现默认字符串长度,decimal精度,entity自动注册和配置

文章以efcore 2.0.0-preview2.测试验证通过。其他版本不保证使用，但是思路不会差太远。源代码,报道越短，事情越严重！文章越短，内容越精悍！

目标：
1.实现entity的自动发现和mapper设置.
2.默认字符串长度，而不是nvarchar(max).
3.decimal设置精度

实现目标1：继承RelationalModelCustomizer，重写Customize方法。

当然，我们也可以重写dbcontext的OnModelCreating方法，but，我们怎么能这么low呢。必须要用点高级玩意是吧，当然这也是更底层的扩展方式。项目里面有多个dbcontext的话，在这里集中扩展管理比较方便。
在然后，这个RelationalModelCustomizer继承自ModelCustomizer。在联想到efcore未来的版本会支持redis，nosql什么的。到时候估计还回有一个osqlModelCustomizer之类的吧，期待中......

实现目标2、3：继承自CoreConventionSetBuilder类，重写CreateConventionSet方法。

重写CreateConventionSet方法，能拿到关键的ConventionSet对象。这个对象囊括了诸多的约定配置等等。比如maxlengthattribute属性标记，stringlength属性标记，timestamp属性标记，表id的自动发现规则等等等。。。
那，我们增加2个小小的约定：字符串默认长度（StringDefaultLengthConvention），和decimal精度设置attribute(DecimalPrecisionAttributeConvention)及fluntapi方式.

文章的最后附efcore 所有的可替换扩展service。

//servie,DI注入替换.
services.AddSingleton<IModelCustomizer, MyRelationalModelCustomizer>();
services.AddSingleton<ICoreConventionSetBuilder, MyCoreConventionSetBuilder>();

//实现entity的自动发现和mapper设置
public class MyRelationalModelCustomizer : RelationalModelCustomizer
{
    public MyRelationalModelCustomizer(ModelCustomizerDependencies dependencies)
        : base(dependencies){}

    public override void Customize(ModelBuilder modelBuilder, DbContext dbContext)
    {
        base.Customize(modelBuilder, dbContext);
        var sp = (IInfrastructure<IServiceProvider>)dbContext;
        var dbOptions = sp.Instance.GetServices<DbContextOptions>();
        foreach (var item in dbOptions)
        {
            if (item.ContextType == dbContext.GetType())
                ConfigureDbContextEntityService.Configure(modelBuilder, item, dbContext);
        }
    }
}

public class MyCoreConventionSetBuilder : CoreConventionSetBuilder
{
    public MyCoreConventionSetBuilder(CoreConventionSetBuilderDependencies dependencies) : base(dependencies){}
    public override ConventionSet CreateConventionSet()
    {
        var conventionSet = base.CreateConventionSet();
        //默认字符串长度，而不是nvarchar(max).
        //为什么要insert(0,obj),则是因为这个默认规则要最优先处理，如果后续有规则的话就直接覆盖了。
        //propertyBuilder.HasMaxLength(32, ConfigurationSource.Convention);
        //理论上我指定了规则的级别为.Convention，应该和顺序就没有关系了。but，还没有完成测试，所以我也不知道
        conventionSet.PropertyAddedConventions.Insert(0, new StringDefaultLengthConvention());
        //decimal设置精度
        conventionSet.PropertyAddedConventions.Add(new DecimalPrecisionAttributeConvention());
        return conventionSet;
    }
}

下面是StringDefaultLengthConvention和DecimalPrecisionAttributeConvention的实现代码

//字符串默认长度
public class StringDefaultLengthConvention : IPropertyAddedConvention
{
    public InternalPropertyBuilder Apply(InternalPropertyBuilder propertyBuilder)
    {
        if (propertyBuilder.Metadata.ClrType == typeof(string))
            propertyBuilder.HasMaxLength(32, ConfigurationSource.Convention);
        return propertyBuilder;
    }
}
//attribute方式设置decimal精度
public class DecimalPrecisionAttributeConvention : PropertyAttributeConvention<DecimalPrecisionAttribute>
{
    public override InternalPropertyBuilder Apply(InternalPropertyBuilder propertyBuilder, DecimalPrecisionAttribute attribute, MemberInfo clrMember)
    {
        if (propertyBuilder.Metadata.ClrType == typeof(decimal))
            propertyBuilder.HasPrecision(attribute.Precision, attribute.Scale);
        return propertyBuilder;
    }

/// <summary>
/// decimal类型设置精度
/// </summary>
/// <param name="propertyBuilder"></param>
/// <param name="precision">精度</param>
/// <param name="scale">小数位数</param>
public static PropertyBuilder<TProperty> HasPrecision<TProperty>(this PropertyBuilder<TProperty> propertyBuilder, int precision = 18, int scale = 4)
{
    //fluntapi方式设置精度  
    ((IInfrastructure<InternalPropertyBuilder>)propertyBuilder).Instance.HasPrecision(precision, scale);

    return propertyBuilder;
}

public static InternalPropertyBuilder HasPrecision(this InternalPropertyBuilder propertyBuilder, int precision, int scale)
{
    propertyBuilder.Relational(ConfigurationSource.Explicit).HasColumnType($"decimal({precision},{scale})");

    return propertyBuilder;
}

以上就是实现的代码，就这么几行。嗯，还是挺简单的.

以下，则是efcore的源代码。展示了如此之多的可扩展。随着DI的运用和微软的开放，嗯。用烂啦，用炸拉(^_^)
