将EntityFrameworkCore生成的SQL语句输出到控制台
参考文档如下
EF Core 日志记录要求使用一个或多个日志记录提供程序配置的 ILoggerFactory。
日志记录-EF Core | Microsoft Docs
安装适当的包后，应用程序应创建 Server.loggerfactory 的单一实例/全局实例。 例如，使用控制台记录器：
public static readonly ILoggerFactory MyLoggerFactory
= LoggerFactory.Create(builder => { builder.AddConsole(); });然后，应该在 DbContextOptionsBuilder 上向 EF Core 注册此单一实例/全局实例。 例如:
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
=> optionsBuilder
.UseLoggerFactory(MyLoggerFactory) // Warning: Do not create a new ILoggerFactory instance each time
.UseSqlServer(
@"Server=(localdb)\mssqllocaldb;Database=EFLogging;Trusted_Connection=True;ConnectRetryCount=0");筛选记录内容
应用程序可以通过在 ILoggerProvider 上配置筛选器来控制要记录的内容。 例如:
public static readonly ILoggerFactory MyLoggerFactory
= LoggerFactory.Create(builder =>
{
builder
.AddFilter((category, level) =>
category == DbLoggerCategory.Database.Command.Name
&& level == LogLevel.Information)
.AddConsole();
});abp中使用
选择 .EntityFrameworkCore 项目
找到 DbContext
添加如下代码
public static readonly ILoggerFactory MyLoggerFactory
= LoggerFactory.Create(builder =>
{
builder
.AddFilter((category, level) =>
category == DbLoggerCategory.Database.Command.Name
&& level == LogLevel.Information)
.AddConsole();
});
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
=> optionsBuilder
.UseLoggerFactory(MyLoggerFactory)
.EnableSensitiveDataLogging(true);使用 Hangfire
添加nuget 包 Hangfire ...
getting-started Hangfire
- 找到并修改 **HttpApiHostModule
在 Startup.cs 直接进入
using System;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;
using Volo.Abp;
namespace MyBookStore
{
public class Startup
{
public IServiceProvider ConfigureServices(IServiceCollection services)
{
services.AddApplication(options =>
{
options.UseAutofac();
});
return services.BuildServiceProviderFromFactory();
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env, ILoggerFactory loggerFactory)
{
app.InitializeApplication();
}
}
} - 添加使用的Configure
private void ConfigureHangfire(ServiceConfigurationContext context, IConfigurationRoot Configuration)
{
// https://github.com/marcoCasamento/Hangfire.Redis.StackExchange
context.Services.AddHangfire(configuration =>
{
configuration.UseRedisStorage(Configuration["Redis:Configuration"]);
});
////https://github.com/perrich/Hangfire.MemoryStorage
//context.Services.AddHangfire(config =>
//{
// config.UseMemoryStorage();
//});
// https://docs.hangfire.io/en/latest/getting-started/aspnet-core-applications.html
//// Add Hangfire services.
//context.Services.AddHangfire(configuration => configuration
// .SetDataCompatibilityLevel(CompatibilityLevel.Version_170)
// .UseSimpleAssemblyNameTypeSerializer()
// .UseRecommendedSerializerSettings()
// .UseSqlServerStorage(Configuration.GetConnectionString("HangfireConnection"), new SqlServerStorageOptions
// {
// CommandBatchMaxTimeout = TimeSpan.FromMinutes(5),
// SlidingInvisibilityTimeout = TimeSpan.FromMinutes(5),
// QueuePollInterval = TimeSpan.Zero,
// UseRecommendedIsolationLevel = true,
// UsePageLocksOnDequeue = true,
// DisableGlobalLocks = true
// }));
// Add the processing server as IHostedService
context.Services.AddHangfireServer();
context.Services.AddTransient();
} - 使用 Hangfire
public class HangfireService
{
private readonly ILibraryService _service;
public HangfireService(ILibraryService service)
{
_service = service;
}
public async Task AddLibraryDto(LibraryDto model)
{
Console.WriteLine($"HangfireService 开始 在：{DateTime.Now.ToLongTimeString()} 启动");
await _service.AddLibraryDto(model);
Console.WriteLine($"HangfireService 结束 在：{DateTime.Now.ToLongTimeString()}");
}
//private IServiceProvider serviceProvider { get; }
//public HangfireService(IServiceProvider _serviceProvider)
//{
// serviceProvider = _serviceProvider;
//}
//public async Task AddLibraryDto(LibraryDto model)
//{
// Console.WriteLine($"HangfireService 开始 在：{DateTime.Now.ToLongTimeString()} 启动");
// using (var serviceScope = serviceProvider.GetService().CreateScope())
// {
// var service = serviceScope.ServiceProvider.GetService();
// await service.AddLibraryDto(model);
// }
// Console.WriteLine($"HangfireService 结束 在：{DateTime.Now.ToLongTimeString()}");
//}
}
- test
[HttpGet("AddLibrary")]
public async Task AddLibrary()

Console.WriteLine($"LibraryController 结束 在：{DateTime.Now.ToLongTimeString()}");
watch.Stop();//停止计时
Console.WriteLine("耗时:" + (watch.ElapsedMilliseconds));//输出时间 毫秒
var watch2 = new Stopwatch();

}

return model;
