FreeSql导航参考官方地址
聚合根实验室 | FreeSql 官方文档
继承IReadOnlyRepository接口实现用FreeSql实现所有功能即可 关键CRUD代码 //默认删除public Task DeleteAsync(TKey id, bool autoSave false, CancellationToken cancellationToken default){return FreeSql.DeleteT(new { Id id }).ExecuteAffrowsAsync(cancellationToken);}public Task DeleteDirectAsync(ExpressionFuncT, bool predicate, CancellationToken cancellationToken default){return FreeSql.DeleteT().Where(predicate).ExecuteAffrowsAsync(cancellationToken);}//批量删除public Task DeleteManyAsync(IEnumerableTKey ids, bool autoSave false, CancellationToken cancellationToken default){return FreeSql.DeleteT(ids).ExecuteAffrowsAsync(cancellationToken);}//默认Getpublic TaskT GetAsync(TKey id, bool includeDetails true, CancellationToken cancellationToken default){object dywhere new { Id id };var query FreeSql.GetAggregateRootRepositoryT().Select.WhereDynamic(dywhere);// FreeSql.QueryableT().WhereDynamic(dywhere); FreeSqlHelper.SetNavigate(query);return query.ToOneAsync(cancellationToken);}//默认GetListpublic TaskIQueryableT GetQueryableAsync(){ISelectT queryable;if (_httpContextAccessor.HttpContext.Request.Query.Any(q q.Key Sorting)){string sorting _httpContextAccessor.HttpContext.Request.Query[Sorting];queryable FreeSql.QueryableT().OrderBy(sorting);}else{queryable FreeSql.QueryableT();}FreeSqlHelper.SetNavigate(queryable);return Task.FromResult(queryable.AsQueryable());}//默认Postpublic async TaskT InsertAsync(T entity, bool autoSave false, CancellationToken cancellationToken default){SetEntity(entity);await FreeSql.GetAggregateRootRepositoryT().InsertAsync(entity,cancellationToken);return entity;}
FreeSqlHelper.cs代码 public class FreeSqlHelper{/// summary/// 设置导航/// /summary/// typeparam nameT/typeparam/// param namequery/parampublic static void SetNavigateT(FreeSql.ISelectT query) {var type typeof(T);MemberInfo[] myMembers type.GetProperties();foreach (MemberInfo myMember in myMembers){var navigateAttribute myMember.GetCustomAttributeFreeSql.DataAnnotations.NavigateAttribute();if (navigateAttribute ! null){query.IncludeByPropertyName(myMember.Name);}}}}
明细表id使用雪花漂移算法生成引用Yitter.IdGenerator库请自行nuget下载
调用YitIdHelper.NextId()生成没有数据库的自增字段功能使用自增的问题很多 新增BaseCrudAppService类代码直接从官方的CrudAppService里复制即可利用批量替换把CrudAppService替换为BaseCrudAppService
如图 新增FilterAsync与DeleteBulkAsync实现动态查询与批量删除功能 新增后的结果如图 freesql动态查询功能很强大日期区间支持年月日期等请参见下图示例说明 SearchCondition代码 public class SearchCondition{/// summary/// 动态过滤条件/// /summarypublic DynamicFilterInfo FilterInfo { get; set; }new();/// summary/// 当前页/// /summarypublic int CurrentPage { get; set; } 1;/// summary/// 每页显示记录条数/// /summarypublic int PageSize { get; set; } 50;/// summary/// 排序/// /summarypublic string Sorting { get; set; } string.Empty;}
IBaseRepository代码如图只是为了在BaseCrudAppService能获取到freesql Enum实体类代码由代码生成器生成
[Serializable]
[Table(TSYS_Enum)]
public class Enum : BaseAuditedAggregateRootGuid
{/// summary/// 字典群组/// /summarypublic int EnumGroup { get; set; }/// summary/// 字典类型/// /summarypublic int EnumType { get; set; } 1;/// summary/// 字典代码/// /summary[StringLength(100)]public string EnumCode { get; set; }/// summary/// 说明/// /summary[StringLength(100)]public string EnumDesc { get; set; }/// 备注/// /summary[StringLength(500)]public string Remark { get; set; }/// summary/// 数据状态 0未提交1审核中2已审核/// /summarypublic byte Status { get; set; }/// summary/// 禁用状态/// /summarypublic byte ForbidStatus { get; set; }/// summary/// 禁用人/// /summarypublic Guid?

ApproverId { get; set; }/// summary/// 审核日期/// /summarypublic DateTime? ApproveDate { get; set; }[FreeSql.DataAnnotations.Navigate(nameof(EnumItem.EnumId))]public virtual ListEnumItem Details { get; set; }
明细表实体类 [Serializable][Table(TSYS_EnumItem)]public class EnumItem : CreationAuditedEntitylong{/// summary/// 主表key/// /summarypublic Guid EnumId { get; set; }/// summary/// 显示值/// /summary[StringLength(100)]public string EnumItemName { get; set; }/// summary/// 存储值/// /summary[StringLength(100)]public string EnumItemValue { get; set; }/// summary/// 说明/// /summary[StringLength(100)]public string EnumItemDesc { get; set; }/// summary/// 行号/// /summarypublic int Num { get; set; } 1;/// 备注/// /summary[StringLength(500)]public string Remark { get; set; }/// summary/// 数据状态 0未提交1审核中2已审核/// /summarypublic byte Status { get; set; }/// summary/// 禁用状态/// /summarypublic byte ForbidStatus { get; set; }/// summary/// 禁用人/// /summarypublic Guid?

ApproverId { get; set; }/// summary/// 审核日期/// /summarypublic DateTime? ApproveDate { get; set; }public virtual Enum Enum { get; set; } }
把原来的CrudAppService改为BaseCrudAppService即可这样只要继承了BaseCrudAppService所有的业务层都有了爽不爽啊再也不用辛苦的做码农了。
