NetCore HttpPatch EFCore 部分修改
参考博文 :https://www.cnblogs.com/lwqlun/p/10433615.html
首先 安装Nuget包
Microsoft.AspNetCore.JsonPatch
有一个注意事项 必须使用 NewtonsoftJson 使用System.Text.Json 会出现422的模型错误

Service 层代码 public async Task<IndustryTypeDto> PartUpdateAsync(int id, JsonPatchDocument<IndustryTypeForUpdate> target, UserInfo user, CancellationToken cancellationToken) { var tran = await BeginTransactionAsync(cancellationToken); try { var existingEntity = await Repository<IIndustryTypeRepository>().LoadEntityAsync(id, cancellationToken); var modifyEntity = ExpressMapper.Mapper.Map<IndustryType, IndustryTypeForUpdate>(existingEntity);
target.ApplyTo(modifyEntity);
ExpressMapper.Mapper.Map(modifyEntity, existingEntity);
await Repository<IIndustryTypeRepository>().UpdateAsync(existingEntity, cancellationToken); if (tran != null) { await tran.CommitAsync(cancellationToken); } return await Repository<IIndustryTypeRepository>().GetAsync(id, true, cancellationToken); } catch { if (tran != null) { await tran.RollbackAsync(cancellationToken); } throw; } }
Controller 代码
[HttpPatch("{id}")] public async Task<IActionResult> PartModify(int id, [FromBody] JsonPatchDocument<IndustryTypeForUpdate> modifyModel,CancellationToken cancellationToken) { var callResult=await _service.PartUpdateAsync(id,modifyModel,Identity,cancellationToken); return Ok(callResult); }
效果图:
原有值
patch请求后效果图:
