Mapster非映射

Question

我将Mapster与DI结合使用，并试图映射从WS接收到的对象。我遵循了这个指南https://github.com/MapsterMapper/Mapster/wiki/Dependency-Injection#mapping

我注册了TypeAdapterConfig和ServiceMapper

var config = new TypeAdapterConfig();
services.AddSingleton(config);
services.AddScoped<IMapper, ServiceMapper>();

黑名单类包含卡片的集合，但是webservice返回的数组是long，这是我重新映射到对象的。

public class BlacklistMapper : IRegister
{
    void IRegister.Register(TypeAdapterConfig config)
    {
        config.NewConfig<long, Internal.BlacklistCard>()
            .Map(dest => dest.Cuid, source => source);

        config.NewConfig<SzWebService.BlackList, Internal.Blacklist>()
            .Map(dest => dest.Id, source => source.iBlacklistId)
            .Map(dest => dest.Crc, source => source.iBlackListCRC)
            .Map(dest => dest.Cards, source => source.lCuid);
    }
}

在构造器中注入映射器

 private readonly IMapper _mapper;

 public Service(IMapper mapper)
 {
     _logger = logger;
 }

最后这样称呼它

_mapper.Map<Blacklist>(response.mBlackListData)

结果总是带有默认值的对象。

Answer 1

步骤1-通过实现创建配置

public class BlacklistMapper : IRegister
{
    void Register(TypeAdapterConfig config)
    {
        config.NewConfig<SzWebService.BlackList, Internal.Blacklist>()
            .Map(...)
            .Map(...);
    }
}

步骤2-注册配置

您可以显式注册配置：

var config = new TypeAdapterConfig();

// Explicitly apply a specific configuration
config.Apply(new BlackListMapper());

services.AddSingleton(config);
services.AddScoped<IMapper, ServiceMapper>();

或者让Mapster扫描您的程序集以获得IRegister实现：

// Scan & apply IRegisters automatically.
config.Scan(Assembly.GetExecutingAssembly());
