多上下文配置(多个数据库的使用)
项目
CanDoo.Test.Core通过Nuget添加对包OsharpNS的引用配置文件
appsettings.Development.json中添加OSharp:DbContexts:MySqlAudit连接参数
"MySqlAudit": {
"DbContextTypeName": "CanDoo.Test.Core.Entity.MySqlAuditDbContext,OSharp.EntityFrameworkCore",//这里要注意下
"ConnectionString": "Server=localhost;Port=3306;UserId=root;Password=******;Database=CanDoo.Test.Audit;charset='utf8';Allow User Variables=True",
"DatabaseType": "MySql",
"LazyLoadingProxiesEnabled": true,
"AuditEntityEnabled": true,
"AutoMigrationEnabled": true
}
- 新建
CanDoo.Test.Core.Entity.MySqlAuditDbContext上下文
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.EntityFrameworkCore;
using OSharp.Entity;
namespace CanDoo.Test.Core.Entity
{
public class MySqlAuditDbContext : DbContextBase
{
public MySqlAuditDbContext(DbContextOptions options, IEntityManager entityManager, IServiceProvider serviceProvider) : base(options, entityManager, serviceProvider)
{
}
}
}
- 创建
CanDoo.Test.Web.Startups.MySqlAuditMigrationPack迁移模块
using System;
using OSharp.Entity;
using OSharp.Entity.MySql;
using CanDoo.Test.Core.Entity;
using CanDoo.Test.Web.Startups;
namespace CanDoo.Test.Web.Startups
{
/// <summary>
/// MySqlAudit迁移模块
/// </summary>
public class MySqlAuditMigrationPack : MigrationPackBase<MySqlAuditDbContext>
{
/// <summary>
/// 获取 模块启动顺序，模块启动的顺序先按级别启动，级别内部再按此顺序启动，
/// 级别默认为0，表示无依赖，需要在同级别有依赖顺序的时候，再重写为>0的顺序值
/// </summary>
public override int Order => 2;
protected override DatabaseType DatabaseType { get; } = DatabaseType.MySql;
protected override MySqlAuditDbContext CreateDbContext(IServiceProvider scopedProvider)
{
return new MySqlAuditDesignTimeDbContextFactory(scopedProvider).CreateDbContext(new string[0]);
}
//针对多库连接的，需要在EntityConfiguration部分增加以下代码，指定DbContext
//public override Type DbContextType { get; } = typeof(MySqlAuditDbContext);
}
}
using System;
using System.Reflection;
using Microsoft.EntityFrameworkCore;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using OSharp.Core.Options;
using OSharp.Data;
using OSharp.Entity;
using OSharp.Exceptions;
using OSharp.Extensions;
using OSharp.Reflection;
using CanDoo.Test.Core.Entity;
namespace CanDoo.Test.Web.Startups
{
public class MySqlAuditDesignTimeDbContextFactory : DesignTimeDbContextFactoryBase<MySqlAuditDbContext>
{
private readonly IServiceProvider _serviceProvider;
public MySqlAuditDesignTimeDbContextFactory()
{ }
public MySqlAuditDesignTimeDbContextFactory(IServiceProvider serviceProvider)
{
_serviceProvider = serviceProvider;
}
public override string GetConnectionString()
{
if (_serviceProvider == null)
{
IConfiguration configuration = Singleton<IConfiguration>.Instance;
string str = configuration["OSharp:DbContexts:MySqlAudit:ConnectionString"]; //这里是配置节点的信息 记得修改
return str;
}
OsharpOptions options = _serviceProvider.GetOSharpOptions();
OsharpDbContextOptions contextOptions = options.GetDbContextOptions(typeof(DefaultDbContext));
if (contextOptions == null)
{
throw new OsharpException($"上下文“{typeof(MySqlAuditDbContext)}”的配置信息不存在");
}
return contextOptions.ConnectionString;
}
public override IEntityManager GetEntityManager()
{
if (_serviceProvider != null)
{
return _serviceProvider.GetService<IEntityManager>();
}
IEntityConfigurationTypeFinder typeFinder = new EntityConfigurationTypeFinder(new AppDomainAllAssemblyFinder());
IEntityManager entityManager = new EntityManager(typeFinder);
entityManager.Initialize();
return entityManager;
}
public override bool LazyLoadingProxiesEnabled()
{
if (_serviceProvider == null)
{
IConfiguration configuration = Singleton<IConfiguration>.Instance;
return configuration["OSharp:DbContexts:MySqlAudit:LazyLoadingProxiesEnabled"].CastTo(false); //这里是配置节点的信息 记得修改
}
OsharpOptions options = _serviceProvider.GetOSharpOptions();
OsharpDbContextOptions contextOptions = options.GetDbContextOptions(typeof(DefaultDbContext));
if (contextOptions == null)
{
throw new OsharpException($"上下文“{typeof(MySqlAuditDbContext)}”的配置信息不存在");
}
return contextOptions.LazyLoadingProxiesEnabled;
}
public override DbContextOptionsBuilder UseSql(DbContextOptionsBuilder builder, string connString)
{
string entryAssemblyName = Assembly.GetExecutingAssembly().GetName().Name;
Console.WriteLine($"entryAssemblyName: {entryAssemblyName}");
return builder.UseMySql(connString, b => b.MigrationsAssembly(entryAssemblyName));
}
}
}
- 审计功能相关的表使用新的上下文，
CanDoo.Test.EntityConfiguration.Systems中Audit开头的3个文件都增加以下配置代码，指定使用MySqlAuditDbContext
public override Type DbContextType { get; } = typeof(MySqlAuditDbContext); //新增此行代码 指定使用MySqlAuditDbContext 未指定的还是使用DefaultDbContext
using System;
using System.Collections.Generic;
using System.Text;
using CanDoo.Test.Core.Entity;
using CanDoo.Test.Systems.Entities;
using Microsoft.EntityFrameworkCore.Metadata.Builders;
using OSharp.Entity;
namespace CanDoo.Test.EntityConfiguration.Systems
{
public class AuditPropertyConfiguration : EntityTypeConfigurationBase<AuditProperty, Guid>
{
public override Type DbContextType { get; } = typeof(MySqlAuditDbContext); //新增此行代码 指定使用MySqlAuditDbContext 未指定的还是使用DefaultDbContext
/// <summary>
/// 重写以实现实体类型各个属性的数据库配置
/// </summary>
/// <param name="builder">实体类型创建器</param>
public override void Configure(EntityTypeBuilder<AuditProperty> builder)
{
builder.HasIndex(m => m.AuditEntityId);
builder.HasOne(m => m.AuditEntity).WithMany(n => n.Properties).HasForeignKey(m => m.AuditEntityId);
}
}
}
在程序包管理控制台中执行
Add-Migration -Context MySqlAuditDbContext newDbContext，创建迁移脚本，因系统中存在2个DbContext，所以需要指定上下文-Context MySqlAuditDbContext在程序包管理控制台中执行
update-database -Context MySqlAuditDbContext至此，数据库中新生成了一个库，库中包含用于审计功能的三张表
