Abp项目模板使用Oracle数据库包括系统权限管理 by dacong

参考：Abp项目的创建以及Oracle的支持

aspnet-zero-core 使用MysqL数据库 http://www.sohu.com/a/162365978_468635

abp项目是可以支持任何数据库的，需要数据库支持entityframework可以无缝移植。

测试环境：oracle11g,abp 3.2.5,vs2017

Abp项目使用Oracle数据库，支持module zero。支持所有用户管理、权限管理、角色管理等。

1、建立项目的时候选择"module zero"，

2、添加Oracle.ManagedDataAccess.EntityFramework包从nuget

3、配合app.config，保证oracle的连接正常

4、删除Migrations 目录已日期开头的.cs文件，如201707261347311_Initial_Migration.cs，201710131316266_UpgradedTo_ABP_3.1.cs

5、修改如下文件：

public class MESDbContext : AbpZeroDbContext<Tenant,Role,User>
{
//TODO: Define an IDbSet for your Entities...


/* NOTE:
* Setting "Default" to base class helps us when working migration commands on Package Manager Console.
* But it may cause problems when working Migrate.exe of EF. If you will apply migrations on command line,do not
* pass connection string name to base classes. ABP works either way. by dacong
*/
public MESDbContext()
: base("Default")
{
//Default要与app.config的一致，把oracle自动配置的OracleContext改成default
}


/* NOTE:
* This constructor is used by ABP to pass connection string defined in MESDataModule.PreInitialize.
* Notice that,actually you will not directly create an instance of MESDbContext since ABP automatically handles it.
*/
public MESDbContext(string nameOrConnectionString)
: base(nameOrConnectionString)
{


}


//This constructor is used in tests
public MESDbContext(DbConnection existingConnection)
: base(existingConnection,false)
{


}


public MESDbContext(DbConnection existingConnection,bool contextOwnsConnection)
: base(existingConnection,contextOwnsConnection)
{


}
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{


modelBuilder.HasDefaultSchema("ABP");
base.OnModelCreating(modelBuilder);
//EntityTypeAssemblyQualifiedName字段过长
modelBuilder.Entity<NotificationInfo>().Property(e => e.EntityTypeAssemblyQualifiedName).HasColumnName("EntityTypeAssemblyQn");
modelBuilder.Entity<NotificationSubscriptionInfo>().Property(e => e.EntityTypeAssemblyQualifiedName).HasColumnName("EntityTypeAssemblyQn");
modelBuilder.Entity<TenantNotificationInfo>().Property(e => e.EntityTypeAssemblyQualifiedName).HasColumnName("EntityTypeAssemblyQn");
}

public class MESDataModule : AbpModule
{
public override void PreInitialize()
{
//Database.SetInitializer(new CreateDatabaseIfNotExists<MESDbContext>());
Configuration.UnitOfWork.IsolationLevel = System.Transactions.IsolationLevel.ReadCommitted;//ORA-08177
Configuration.DefaultNameOrConnectionString = "Default";
}


public override void Initialize()
{
IocManager.RegisterAssemblyByConvention(Assembly.GetExecutingAssembly());
Database.SetInitializer<MESDbContext>(null);
}
}

6、使用程序包管理器控制台里面输入@H_403_144@Add-Migration init

会生成移植文件，如下

public partial class abp_init : DbMigration
{
public override void Up()
{
CreateTable(
"ABP.AbpAuditLogs",
c => new
{
Id = c.Decimal(nullable: false,precision: 19,scale: 0,identity: true),
TenantId = c.Decimal(precision: 10,scale: 0),
UserId = c.Decimal(precision: 19,
ServiceName = c.String(maxLength: 256),
MethodName = c.String(maxLength: 256),
Parameters = c.String(maxLength: 1024),
ExecutionTime = c.DateTime(nullable: false),
ExecutionDuration = c.Decimal(nullable: false,precision: 10,
ClientIpAddress = c.String(maxLength: 64),
ClientName = c.String(maxLength: 128),
BrowserInfo = c.String(maxLength: 256),
Exception = c.String(maxLength: 2000),
ImpersonatorUserId = c.Decimal(precision: 19,
ImpersonatorTenantId = c.Decimal(precision: 10,
CustomData = c.String(maxLength: 2000),
},
annotations: new Dictionary<string,object>
{
{ "DynamicFilter_AuditLog_MayHaveTenant","EntityFramework.DynamicFilters.DynamicFilterDefinition" },
})
.PrimaryKey(t => t.Id);

CreateTable(
"ABP.AbpBackgroundJobs",
JobType = c.String(nullable: false,maxLength: 512),
JobArgs = c.String(nullable: false),
TryCount = c.Decimal(nullable: false,precision: 5,
NextTryTime = c.DateTime(nullable: false),
LastTryTime = c.DateTime(),
IsAbandoned = c.Decimal(nullable: false,precision: 1,
Priority = c.Decimal(nullable: false,precision: 3,
CreationTime = c.DateTime(nullable: false),
CreatorUserId = c.Decimal(precision: 19,
})
.PrimaryKey(t => t.Id)
.Index(t => new { t.IsAbandoned,t.NextTryTime });

CreateTable(
"ABP.AbpFeatures",
Name = c.String(nullable: false,maxLength: 128),
Value = c.String(nullable: false,maxLength: 2000),
EditionId = c.Decimal(precision: 10,
Discriminator = c.String(nullable: false,object>
{
{ "DynamicFilter_EditionFeatureSetting_MayHaveTenant",
{ "DynamicFilter_FeatureSetting_MayHaveTenant",
{ "DynamicFilter_TenantFeatureSetting_MayHaveTenant",
})
.PrimaryKey(t => t.Id)
.ForeignKey("ABP.AbpEditions",t => t.EditionId,cascadeDelete: true)
.Index(t => t.EditionId);

CreateTable(
"ABP.AbpEditions",maxLength: 32),
DisplayName = c.String(nullable: false,maxLength: 64),
IsDeleted = c.Decimal(nullable: false,
DeleterUserId = c.Decimal(precision: 19,
DeletionTime = c.DateTime(),
LastModificationTime = c.DateTime(),
LastModifierUserId = c.Decimal(precision: 19,object>
{
{ "DynamicFilter_Edition_SoftDelete",
})
.PrimaryKey(t => t.Id);

CreateTable(
"ABP.AbpLanguages",maxLength: 10),
Icon = c.String(maxLength: 128),
IsDisabled = c.Decimal(nullable: false,object>
{
{ "DynamicFilter_ApplicationLanguage_MayHaveTenant",
{ "DynamicFilter_ApplicationLanguage_SoftDelete",
})
.PrimaryKey(t => t.Id);

CreateTable(
"ABP.AbpLanguageTexts",
LanguageName = c.String(nullable: false,
Source = c.String(nullable: false,
Key = c.String(nullable: false,maxLength: 256),
Value = c.String(nullable: false),object>
{
{ "DynamicFilter_ApplicationLanguageText_MayHaveTenant",
})
.PrimaryKey(t => t.Id);

8、给web项目也增加racle.ManagedDataAccess.EntityFramework，并修改web.cong。

9、启动web项目。

目前这个版本在web项目第一次启动时或保存，刷新后可以正常使用。
