ABP.Net Core使用教程(三)记录数据库脚本日志

Microsoft.Extensions.Logging; using System; namespace AbpDemo.EntityFrameworkCore.Logger { public class EFLogger : ILogger { public Castle.Core.Logging.ILogger Logger { get; set; } private readonly string _categoryName; public EFLogger(string categoryName, Castle.Core.Logging.ILogger logger) { this._categoryName = categoryName; this.Logger = logger; } public bool IsEnabled(LogLevel logLevel) => true; public void Log<TState>(LogLevel logLevel, EventId eventId, TState state, Exception exception, Func<TState, Exception, string> formatter) { //ef core执行数据库查询时的categoryName为Microsoft.EntityFrameworkCore.Database.Command,日志级别为Information var logContent2 = formatter(state, exception); if (_categoryName == "Microsoft.EntityFrameworkCore.Database.Command" && logLevel == LogLevel.Information) { var logContent = formatter(state, exception); Logger.Warn(logContent); } } public IDisposable BeginScope<TState>(TState state) => null; } } View Code

EfLoggerProvider.cs

using Microsoft.Extensions.Logging;

namespace AbpDemo.EntityFrameworkCore.Logger
{
    public class EfLoggerProvider : ILoggerProvider
    {
        public Castle.Core.Logging.ILogger Logger;

        public EfLoggerProvider(Castle.Core.Logging.ILogger logger)
        {
            Logger = logger;
        }

        public ILogger CreateLogger(string categoryName)
        {
            return new EFLogger(categoryName, Logger);
        }

        public void Dispose()
        {
        }
    }
}

2, 修改AbpDemoDbContextConfigurer.cs

using System.Data.Common;
using Microsoft.EntityFrameworkCore;
using Microsoft.Extensions.Logging;

namespace AbpDemo.EntityFrameworkCore
{
    public static class AbpDemoDbContextConfigurer
    {
        public static void Configure(DbContextOptionsBuilder<AbpDemoDbContext> builder, string connectionString,
            LoggerFactory loggerFactory)
        {
            builder.UseLoggerFactory(loggerFactory).UseSqlServer(connectionString);
            builder.EnableSensitiveDataLogging(); //日志显示脚本参数
        }

        public static void Configure(DbContextOptionsBuilder<AbpDemoDbContext> builder, DbConnection connection,
            LoggerFactory loggerFactory)
        {
            builder.UseLoggerFactory(loggerFactory).UseSqlServer(connection);
            builder.EnableSensitiveDataLogging(); //日志显示脚本参数
        }
    }
}

3, 修改AbpDemoEntityFrameworkModule.cs   构建EfLoggerProvider类并提供给配置类使用

using Abp.EntityFrameworkCore.Configuration;
using Abp.Modules;
using Abp.Reflection.Extensions;
using Abp.Zero.EntityFrameworkCore;
using AbpDemo.EntityFrameworkCore.Logger;
using AbpDemo.EntityFrameworkCore.Seed;

namespace AbpDemo.EntityFrameworkCore
{
    [DependsOn(
        typeof(AbpDemoCoreModule),
        typeof(AbpZeroCoreEntityFrameworkCoreModule))]
    public class AbpDemoEntityFrameworkModule : AbpModule
    {
        /* Used it tests to skip dbcontext registration, in order to use in-memory database of EF Core */
        public bool SkipDbContextRegistration { get; set; }

        public bool SkipDbSeed { get; set; }

        public override void PreInitialize()
        {
            if (!SkipDbContextRegistration)
            {
                Configuration.Modules.AbpEfCore().AddDbContext<AbpDemoDbContext>(options =>
                {
                    if (options.ExistingConnection != null)
                    {
                        AbpDemoDbContextConfigurer.Configure(options.DbContextOptions, options.ExistingConnection,
                            DbLoggerFactory);
                    }
                    else
                    {
                        AbpDemoDbContextConfigurer.Configure(options.DbContextOptions, options.ConnectionString,
                            DbLoggerFactory);
                    }
                });
            }
        }

        public override void Initialize()
        {
            IocManager.RegisterAssemblyByConvention(typeof(AbpDemoEntityFrameworkModule).GetAssembly());
        }

        public override void PostInitialize()
        {
            if (!SkipDbSeed)
            {
                SeedHelper.SeedHostDb(IocManager);
            }
        }

        private static Microsoft.Extensions.Logging.LoggerFactory _loggerFactory; 

        private Microsoft.Extensions.Logging.LoggerFactory DbLoggerFactory
        {
            get
            {
                if (null == _loggerFactory)
                {
                    _loggerFactory = new Microsoft.Extensions.Logging.LoggerFactory();
                    //_loggerFactory.AddProvider(new EfLoggerProvider(IocManager.Resolve<Castle.Core.Logging.ILogger>()));
                    _loggerFactory.AddProvider(new EfLoggerProvider(Logger));
                }

                return _loggerFactory;
            }
        }
    }
}

4, 修复AbpDemoDbContextFactory.cs 的报错,传入空日志类就可以了

using Microsoft.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore.Design;
using Microsoft.Extensions.Configuration;
using AbpDemo.Configuration;
using AbpDemo.Web;

namespace AbpDemo.EntityFrameworkCore
{
    /* This class is needed to run "dotnet ef ..." commands from command line on development. Not used anywhere else */
    public class AbpDemoDbContextFactory : IDesignTimeDbContextFactory<AbpDemoDbContext>
    {
        public AbpDemoDbContext CreateDbContext(string[] args)
        {
            var builder = new DbContextOptionsBuilder<AbpDemoDbContext>();
            var configuration = AppConfigurations.Get(WebContentDirectoryFinder.CalculateContentRootFolder());

            AbpDemoDbContextConfigurer.Configure(builder,
                configuration.GetConnectionString(AbpDemoConsts.ConnectionStringName), null);

            return new AbpDemoDbContext(builder.Options);
        }
    }
}

这样运行项目, 在Logs.txt中就会显示所有的数据库脚本了

 

我对日志进行了分类存放, 下面是参考的 log4net.config
