1. Create a project

Enter the official website of the ABP framework,http://abp.io/There are two ways to create a framework here, the first is to use the command line, the second is to generate a compressed package directly on the website, this article uses the second method.

1. Click GET STRATED-> select the DIRECT DOWNLOAD method, fill in the project information as follows, after completion, click CREATE NOW to automatically generate an ABP framework compression package

After decompression, use VS2019 to open the solution, the structure directory is shown in the figure, thenSet ABPBookStore.Web as the startup item

2. The database is changed, the database defaults to SQLserver, and now it is replaced with MYSQL.https://dotnet9.com/11978.html

1) Modify the link string in ABPBookStore.Web->appsettings.json, as follows

2) Manage the Nuget package in the "ABPBookStore.EntityFrameworkCore" project, uninstall the "Volo.Abp.EntityFrameworkCore.SqlServer" package,

Browse to install"Volo.Abp.EntityFrameworkCore.MySQL"Package

3) Modify the error prompt

“ABPBookStore.EntityFrameworkCore" project in the ABPBookStoreEntityFrameworkCoreModule.cs fileoptions.UseSQLServer()
is modified to:options.UseMySQL()。
will depend on the project"typeof(AbpEntityFrameworkCoreSqlServerModule)"change into"typeof(AbpEntityFrameworkCoreMySQLModule)". Add corresponding references and delete invalid using references.

In the "ABPBookStore.EntityFrameworkCore.DbMigrations" project, in the ABPBookStoreMigrationsDbContextFactory.CS file in the EntityFrameworkCore folder

Change var builder = new DbContextOptionsBuilder<ABPBookStoreMigrationsDbContext>()
                .UseSqlServer(configuration.GetConnectionString("Default"));

Modify to var builder = new DbContextOptionsBuilder<ABPBookStoreMigrationsDbContext>()
                .UseMySql(configuration.GetConnectionString("Default"));

4) Modify errors in Web items

Delete the Migrator folder under the "ABPBookStore.EntityFrameworkCore.DbMigrations" project and regenerate the solution
 

5) Modification cannot create tableIdentityServerApiSecuritymistake

inABPBookStore.EntityFrameworkCoreproject,"EntityFrameworkCore"Folder, addIdentityServerModelCreatingExtensionsclass. code show as below:

public static class IdentityServerModelCreatingExtensions

{

public static void ConfigureIdentityServerForMySQL(this ModelBuilder builder)

{

// Solve the problem of MySQL migration

// https://github.com/abpframework/abp/issues/1920

builder.Entity<ApiSecret>(b =>

{

// After trying, you can also set it to 400

b.Property(x => x.Value).HasMaxLength(300);

});

builder.Entity<ClientPostLogoutRedirectUri>(b =>

{

b.Property(x => x.PostLogoutRedirectUri).HasMaxLength(300); // or 400 ？

});

builder.Entity<ClientRedirectUri>(b =>

{

b.Property(x => x.RedirectUri).HasMaxLength(300); // or 400 ？

});

builder.Entity<ClientSecret>(b =>

{

b.Property(x => x.Value).HasMaxLength(300); // or 400 ？

});

}

}

inABPBookStoreDbContextIn classOnModelCreatingAt the end of the method, add the following code and add the corresponding using reference:

builder.ConfigureIdentityServer(options =>

{

options.DatabaseProvider = EfCoreDatabaseProvider.MySql;

});

builder.ConfigureIdentityServerForMySQL();

inABPBookStoreDbContextModelCreatingExtensionsIn the fileConfigureABPBookStoreAdd the following code under the method:

builder.ConfigureIdentityServer(options =>

{

options.DatabaseProvider = EfCoreDatabaseProvider.MySql;

});

6) Regenerate the migration

Regenerate the solution, set the ABPBookStore.Web project as the startup project, select Tools -> NuGet Package Management -> Package Management Console, set the default project to "ABPBookStore.EntityFrameworkCore.DbMigrations", enteradd-migrationCommand to regenerate the migration.

 

After the migration is complete, enter update-database to update the database

The project can run
