[从0到1搭建ABP微服务] - 搭建租户管理服务

2024-04-12 18:53:14

一、简介#

ABP模板项目中已经提供了租户登录和管理功能，但是模板项目是单体应用结构，无法单独部署租户服务，所以难以满足微服务的需求。本篇文章将会介绍搭建ABP租户管理服务，并单独部署应用。

二、创建工程#

2.1 创建TenantService.Host服务#

微服务的开发应该是模块化的，所以TenantService.Host服务名没有放在在ABP微服务解决方案中，选择独立搭建、独立部署的方式。

三、安装模块组件#

在大型团队中或者小型精英团队中建议拉取将ABP源码发布本地Nuget包，所有服务引用本地包进行开发。因为无论ABP如何通用也是无法满足企业级后台业务的发展和版本迭代的，有老司机的团队应该要掌握修改ABP底层应用甚至底层框架的能力。

3.1 安装ids4、.net core、ABP等必须组件#

Serilog.Extensions.Hosting Version="3.0.0"
Serilog.Sinks.File Version="4.0.0"
Serilog.Sinks.Elasticsearch Version="6.5.0"
Swashbuckle.AspNetCore Version="5.0.0-rc4"
IdentityServer4.AccessTokenValidation Version="3.0.0"
Microsoft.Extensions.Caching.StackExchangeRedis Version="3.1.0"
Microsoft.AspNetCore.DataProtection.StackExchangeRedis Version="3.1.0"
Volo.Abp.AspNetCore.MultiTenancy Version="2.0.1"
Volo.Abp.AuditLogging.EntityFrameworkCore Version="2.0.1"
Volo.Abp.Autofac Version="2.0.1"
Volo.Abp.EntityFrameworkCore.SqlServer Version="2.0.1"
Volo.Abp.PermissionManagement.EntityFrameworkCore Version="2.0.1"
Volo.Abp.SettingManagement.EntityFrameworkCore Version="2.0.1"
Volo.Abp.TenantManagement.Application Version="2.0.1"
Volo.Abp.TenantManagement.EntityFrameworkCore Version="2.0.1"
Volo.Abp.TenantManagement.HttpApi Version="2.0.1"
Volo.Abp.Identity.Application.Contracts Version="2.0.1"
Volo.Abp.Identity.EntityFrameworkCore Version="2.0.1"
volo.abp.identityserver.entityframeworkcore Version="2.0.1"

四、配置Module#

ABP不仅基于DDD设计，更是基于模块化实现的。

4.1 添加TenantServiceHostModule#

在TenantService.Host根目录中添加TenantServiceHostModule类

4.2 引用依赖#

租户服务关系的ABP应用模块比较多，所以依赖也比其他服务多一些。ABP模块引用会在服务模块启动时载入IOC容器，这样的好处是无需多次引用，只要在Mudule中引用一次就可以。
引用的依赖顺序如下：
AbpAutofacModule
AbpEventBusRabbitMqModule
AbpAspNetCoreMultiTenancyModule
AbpEntityFrameworkCoreSqlServerModule
AbpAuditLoggingEntityFrameworkCoreModule
AbpPermissionManagementEntityFrameworkCoreModule
AbpSettingManagementEntityFrameworkCoreModule
AbpTenantManagementHttpApiModule
AbpTenantManagementEntityFrameworkCoreModule
AbpTenantManagementApplicationModule
AbpIdentityEntityFrameworkCoreModule
AbpIdentityServerEntityFrameworkCoreModule

4.3 注册服务#

与其他服务一样需要注册认证、Swagger、默认语言、数据库服务、redis等，这里就不过多赘述了，ABP文档有详细的解释。

4.4 配置初始化模块#

这里也跟其他服务一样，没有特殊的模块需要初始化。

4.5 TenantServiceHostModule完整代码如下：#
