手把手教你：在.Net 8的ABP框架中，同时集成FreeSql和SqlSugar（附完整代码）

在ABP框架中同时集成FreeSql与SqlSugar的深度实践指南当企业级应用需要同时兼顾开发效率与性能优化时多ORM混搭架构正成为.NET技术栈的新趋势。本文将深入探讨如何在ABP VNext框架中实现FreeSql与SqlSugar的双引擎集成通过模块化设计让两种ORM各展所长。1. 混合ORM架构的设计价值在微服务与模块化开发盛行的当下单一ORM很难满足所有业务场景的需求。FreeSql以零配置、强类型著称特别适合快速迭代的业务模块而SqlSugar凭借卓越的读写性能往往是高频交易场景的首选。ABP框架的依赖注入系统为这种混合架构提供了天然支持。实际项目中最常见的混用场景包括历史模块使用SqlSugar需要保留报表模块依赖FreeSql的复杂查询能力需要对比两种ORM在真实业务中的表现渐进式迁移过程中的过渡方案提示混合架构会增加一定复杂度建议在项目规模达到20个以上领域模型时考虑采用2. 环境准备与基础配置2.1 创建ABP VNext项目使用ABP CLI创建模块化解决方案abp new Acme.BookStore -t app -u mvc --mobile none --database-provider mysql2.2 添加ORM包引用在领域层和基础设施层添加NuGet包!-- FreeSql全家桶 -- PackageReference IncludeFreeSql.Provider.MySql Version3.2.800 / PackageReference IncludeFreeSql.DbContext Version3.2.800 / !-- SqlSugar核心包 -- PackageReference IncludeSqlSugarCore Version5.1.4.59 /2.3 数据库连接配置在appsettings.json中配置多数据库连接ConnectionStrings: { Default: Serverlocalhost;Port3306;DatabaseBookStore;Uidroot;Pwd123456;, ReadReplica: Serverreplica1;Port3306;DatabaseBookStore;Uidreadonly;Pwd123456; }3. 模块化集成方案3.1 FreeSql模块实现创建FreeSqlModule.cs实现ABP模块[DependsOn(typeof(AbpDddModule))] public class FreeSqlModule : AbpModule { public override void ConfigureServices(ServiceConfigurationContext context) { var configuration context.Services.GetConfiguration(); var freeSql new FreeSqlBuilder() .UseConnectionString(DataType.MySql, configuration.GetConnectionString(Default)) .UseAutoSyncStructure(false) // 禁用自动迁移 .UseMonitorCommand(cmd Logger.LogDebug($FreeSql执行{cmd.CommandText})) .Build(); context.Services.AddSingletonIFreeSql(freeSql); context.Services.AddFreeRepository(); } }3.2 SqlSugar模块实现创建SqlSugarModule.cs配置作用域[DependsOn(typeof(AbpDddModule))] public class SqlSugarModule : AbpModule { public override void ConfigureServices(ServiceConfigurationContext context) { context.Services.AddSingletonISqlSugarClient(provider { var config provider.GetRequiredServiceIConfiguration(); return new SqlSugarScope(new ConnectionConfig() { DbType DbType.MySql, ConnectionString config.GetConnectionString(Default), IsAutoCloseConnection true }, db { db.Aop.OnLogExecuting (sql, pars) { Logger.LogInformation($SqlSugar执行{sql}); }; }); }); } }4. 双ORM仓储模式设计4.1 基础仓储抽象类// FreeSql仓储基类 public abstract class FreesqlRepositoryTEntity : DomainService where TEntity : class, IEntity { protected IFreeSql FreeSql LazyServiceProvider.LazyGetRequiredServiceIFreeSql(); public virtual async TaskTEntity GetAsync(long id) { return await FreeSql.SelectTEntity() .Where(x x.Id id) .ToOneAsync(); } } // SqlSugar仓储基类 public abstract class SqlSugarRepositoryTEntity : DomainService where TEntity : class, new() { protected ISqlSugarClient Db LazyServiceProvider.LazyGetRequiredServiceISqlSugarClient(); public virtual async TaskTEntity GetAsync(dynamic id) { return await Db.QueryableTEntity() .InSingleAsync(id); } }4.2 业务仓储实现示例public class BookRepository : SqlSugarRepositoryBook, ITransientDependency { public async TaskListBook GetHotBooksAsync(int count) { return await Db.QueryableBook() .OrderBy(b b.Sales, OrderByType.Desc) .Take(count) .ToListAsync(); } } public class AuthorRepository : FreesqlRepositoryAuthor, ITransientDependency { public async TaskListAuthor GetPopularAuthorsAsync() { return await FreeSql.SelectAuthor() .Include(a a.Books) .Where(a a.Fans 1000) .ToListAsync(); } }5. 应用服务层的最佳实践5.1 多ORM服务注入模式public class BookAppService : ApplicationService { private readonly BookRepository _sqlSugarRepo; private readonly AuthorRepository _freeSqlRepo; public BookAppService( BookRepository sqlSugarRepo, AuthorRepository freeSqlRepo) { _sqlSugarRepo sqlSugarRepo; _freeSqlRepo freeSqlRepo; } public async TaskBookWithAuthorDto GetBookDetailsAsync(long id) { var book await _sqlSugarRepo.GetAsync(id); var author await _freeSqlRepo.GetAsync(book.AuthorId); return new BookWithAuthorDto { Book book, Author author }; } }5.2 事务跨ORM处理方案public async Task CreateOrderAsync(OrderCreateDto input) { using (var uow UnitOfWorkManager.Begin( requiresNew: true, isTransactional: true)) { try { // FreeSql操作 await _freeSqlRepo.InsertAsync(input.Books); // SqlSugar操作 await _sqlSugarRepo.AddAsync(input.Order); await uow.CompleteAsync(); } catch { await uow.RollbackAsync(); throw; } } }6. 性能优化与调试技巧6.1 连接池配置建议ORM类型参数推荐值说明FreeSqlPoolSize100连接池大小SqlSugarConnectionPoolSize50连接池实例数通用IdleTimeout300空闲连接超时(秒)6.2 日志监控配置在appsettings.json中添加Logging: { LogLevel: { FreeSql: Debug, SqlSugar: Information } }6.3 常见问题排查依赖冲突检查Newtonsoft.Json版本是否兼容事务失效确保UnitOfWork作用域正确性能下降监控连接泄露情况迁移差异禁用自动迁移功能在ABP框架中同时使用两种ORM就像为项目配备了瑞士军刀和手术刀——前者应对日常开发游刃有余后者则在性能关键路径上精准高效。经过多个项目的实践验证这种架构特别适合需要兼顾开发速度与运行效率的中大型商业系统。
