将.Net Core 2.2和ASP.NET Boilerplate 4.5升级到.Net Core 3.1和ASP.NET Boilerplate 5.13时出现ObjectMapper错误

如何解决将.Net Core 2.2和ASP.NET Boilerplate 4.5升级到.Net Core 3.1和ASP.NET Boilerplate 5.13时出现ObjectMapper错误

ObjectMapper可在.Net Core 2.2和ASP.NET Boilerplate 4.5上运行->确定
但适用于.Net Core 3.1和ASP.NET Boilerplate 5.13->错误

还必须进行其他设置吗？

我的错误消息：

 "Missing type map configuration or unsupported mapping.\r\n\r\nMapping types:\r\nProd -> ProdDto\r\ncom.myproject.Core.Models.Prod -> com.myproject.Application.Prod.Dto.ProdDto"

我的AppService：

public override async Task<ProdDto> GetAsync(EntityDto<int> input)
{  
    try
    {
        var entity = await _prodManager.GetProdByIdAsync(input.Id);

        var result = ObjectMapper.Map<ProdDto>(entity);

        return result;
    }
    catch (Exception ex)
    {
        throw new UserFriendlyException(ex.Message);
    }
}

我的模块：

[DependsOn(
    typeof(AbpAutoMapperModule))]
public class ProdApplicationModule : AbpModule
{
    public override void PreInitialize()
    {
    }

    public override void Initialize()
    {
        var thisAssembly = typeof(ProdApplicationModule).GetAssembly();

        IocManager.RegisterassemblyByConvention(thisAssembly);

        Configuration.Modules.AbpAutoMapper().Configurators.Add(
            cfg => cfg.AddMaps(thisAssembly)
        );
    }
}

我的个人资料：

public class ProdMapProfile : Profile
{
    public ProdMapProfile()
    {
        CreateMap<Core.Models.Prod,ProdDto>();
    }
}

解决方法

如果您的实体和DTO类未与所有属性（或变量）进行映射，则您可以忽略某些属性（未映射的属性可能会导致缺少映射错误）。

library(themis)
library(recipes)
library(tune)
library(parsnip)
library(workflows)
library(dials)
library(rsample)

xg_mod <- parsnip::boost_tree(mode = "classification",trees = tune(),tree_depth = tune(),min_n = tune(),loss_reduction = tune(),learn_rate = tune()) %>%
    set_engine("xgboost")

xg_grid <- grid_latin_hypercube(over_ratio(range = c(0,1)),trees(),tree_depth(),min_n(),loss_reduction(),learn_rate(),size = 5)

my_recipe <- recipe(class ~ .,data = circle_example) %>%
    step_rose(class,over_ratio = tune())

workflow() %>%
    add_model(xg_mod) %>%
    add_recipe(my_recipe) %>%
    tune_grid(resamples = mc_cv(circle_example,strata = class),grid = xg_grid)

,

当我更新到net core 3.1时，我遇到了同样的问题，要解决该问题，您需要映射Get的结果，请参见您代码上的修改

public override async Task<ProdDto> GetAsync(EntityDto<int> input)
{  
    try
    {
        var entity = await _prodManager.GetProdByIdAsync(input.Id).Result;

        var result = ObjectMapper.Map<ProdDto>(entity);

        return result;
    }
    catch (Exception ex)
    {
        throw new UserFriendlyException(ex.Message);
    }
}

之所以会这样，是因为它试图映射异步响应，所以当您添加.result时，它会起作用。
