abp.netcore框架数据传输模型Dto、实体模型Entity、表字段相关映射

e框架数据传输模型Dto、实体模型Entity、表字段相关映射先说下写这篇⽂章的初衷，让实体和表对应字段映射，数据传输模型dto与实体模型对应字段映射；情况如下1、我的实体模型Entity继承了另外⼀个实体类接⼝，⽬前实体模型Entity跟数据库字段对应不上，通过如下配置，匹配映射：⽂件结构如下：配置解决⽅法：第⼀步：在EntityFrameworkCore，创建⽂件夹EntityMapper，下⾯创建实体映射⽂件ExpertMap。代码如下： public class ExpertMap : IEntityTypeConfiguration { public void Configure(EntityTypeBuilder builder) { e("Expert"); (m => );//主键

ty(m => Name).HasColumnName("Name");//列名 ty(m => Sex).HasColumnName("Sex"); ty(m => zationName).HasColumnName("WorkUnit"); ty(m => Title).HasColumnName("Title"); ty(m => Phone).HasColumnName("Phone"); ty(m => Field).HasColumnName("TechnicalExpertise");

} }第⼆步：配置映射关系⽂件位置：配置信息：贴代码： //配置实体与表映射关系 protected override void OnModelCreating(ModelBuilder modelBuilder) { onfiguration(new ExpertMap());

lCreating(modelBuilder); }2、⽬前实体和表映射了，但是我的数据模型dto和实体没有映射，接下来配置数据模型dto与实体的映射关系。第⼀步：dto的映射关系调整第⼆步：创建⽂件夹Mapper,创建映射⽂件代码如下： public class ExpertMapper { ///

/// ExpertMapper数据传输对象映射 ///

public static void CreateMapper(IMapperConfigurationExpression mapper) { //字段映射 Map().ForMember(dst => Name, opt => m(src => )) .ForMember(dst => Sex, opt => m(src => )) .ForMember(dst => zationName, opt => m(src => it)) .ForMember(dst => Title, opt => m(src => )) .ForMember(dst => Phone, opt => m(src => )) .ForMember(dst => Field, opt => m(src => calExpertise));

Map().ForMember(dst => Name, opt => m(src => )) .ForMember(dst => Sex, opt => m(src => )) .ForMember(dst => zationName, opt => m(src => it)) .ForMember(dst => Title, opt => m(src => )) .ForMember(dst => Phone, opt => m(src => )) .ForMember(dst => Field, opt => m(src => calExpertise)); Map().ForMember(dst => Name, opt => m(src => )) .ForMember(dst => Sex, opt => m(src => )) .ForMember(dst => zationName, opt => m(src => it)) .ForMember(dst => Title, opt => m(src => )) .ForMember(dst => Phone, opt => m(src => )) .ForMember(dst => Field, opt => m(src => calExpertise)); Map< Expert,DetailExpertDto>().ForMember(dst => , opt => m(src => Name)) .ForMember(dst => , opt => m(src => Sex)) .ForMember(dst => it, opt => m(src => zationName)) .ForMember(dst => , opt => m(src => Title )) .ForMember(dst => , opt => m(src => Phone )) .ForMember(dst => calExpertise, opt => m(src => Field )); } }}第三步;映射关系配置贴代码： oMapper().(Mapper);//专家映射信息最后：测试，⾸先，数据库表字段同步：执⾏Add-Migration nameUpdate-database查看数据库表字段是否正确调试增、删、改查接⼝，确定接⼝是否正常即可。
