Mapster


  Mapster 是一个比较小巧、比较快捷的对象映射器,可以将一个对象映射到另一个对象。Fireasy 提供了 Mapster 对 对象映射器 的实现。

  修改配置文件如下:

  • .Net Framework 下的 app.config 或 web.config 文件
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <sectionGroup name="fireasy">
      <section name="objMappers" type="Fireasy.Common.Mapper.Configuration.ObjectMapperConfigurationSectionHandler, Fireasy.Common" />
    </sectionGroup>
  </configSections>
  <fireasy>
    <objMappers default="mapster">
      <mapper name="mapster" type="Fireasy.Mapster.ObjectMapper, Fireasy.Mapster" />
    </objMappers>
  </fireasy>
</configuration>
  • .Net Core 下的 appsettings.json 文件
{
  "fireasy": {
    "objMappers": {
      "default": "mapster",
      "settings": {
        "mapster": {
          "type": "Fireasy.Mapster.ObjectMapper, Fireasy.Mapster"
        }
      }
    }
  }
}

  在 .Net Core 应用中可以使用扩展方法 AddMapster 切换到 Maspter,同时使用 CreateMap 方法进行映射。如下所示:

namespace demo
{
    public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddFireasy().AddMapster(s =>
            {
                s.CreateMap<SysUser, UserDto>()
                  .CreateMap<SysModule, ModuleDto>(t => 
                      t.Map(w => w.Url, w => "http://www.fireasy.cn/" + w.Url))
                  .CreateMap<SysRole, RoleDto>();
                
                //程序集搜索 IRegister
                s.AddRegisters(this.GetType().Assembly);
            });
        }
    }
}
