由于EFCore并没直接生成脚本到txt文件，故而自己画了点时间把实现记录下来，方便给大家参考。
0.安装Microsoft.Extensions.Logging.Debug，我这里是2.1.1版本。
1.新建一个EFCoreDatabaseCmdLog在abp的Core层下，
using Abp.Dependency;
using Castle.Core.Logging;
namespace SensorBroker.Log
{
public static class EFCoreDatabaseCmdLog
{
public static ILogger Logger { get; private set; }
static EFCoreDatabaseCmdLog()
{
Logger = IocManager.Instance.IsRegistered(typeof(ILoggerFactory))
? IocManager.Instance.Resolve<ILoggerFactory>().Create(typeof(EFCoreDatabaseCmdLog))
: NullLogger.Instance;
}
public static void Debug(string logContent)
{
Logger.Debug(logContent);
}
}
}
2.在abp.EntityFrameworkCore层EntityFrameworkCore文件夹下新增2个文件EFLoggerProvider.cs与EFLogger.cs
EFLogger.cs
using Microsoft.Extensions.Logging;
using System;
namespace SensorBroker.EntityFrameworkCore
{
public class EFLogger : ILogger
{
private readonly string categoryName;
public EFLogger(string categoryName) => this.categoryName = categoryName;
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
if (categoryName == "Microsoft.EntityFrameworkCore.Database.Command"
&& logLevel == LogLevel.Information)
{
var logContent = formatter(state, exception);
XXXXX.Log.EFCoreDatabaseCmdLog.Debug(logContent);//xxxx 需要替换成自己的项目名字
}
}
public IDisposable BeginScope<TState>(TState state) => null;
}
}
EFLoggerProvider
using Microsoft.Extensions.Logging;
namespace SensorBroker.EntityFrameworkCore
{
public class EFLoggerProvider : ILoggerProvider
{
public ILogger CreateLogger(string categoryName) => new EFLogger(categoryName);
public void Dispose() { }
}
}
3.修改SensorBrokerDbContextConfigurer.cs文件如下，我这里用的是mysql，请酌情参考。
using System.Data.Common;
using Microsoft.EntityFrameworkCore;
using Microsoft.Extensions.Logging;
namespace SensorBroker.EntityFrameworkCore
{
public static class SensorBrokerDbContextConfigurer
{
public static void Configure(DbContextOptionsBuilder<SensorBrokerDbContext> builder, string connectionString)
{
var loggerFactory = new LoggerFactory();
loggerFactory.AddProvider(new EFLoggerProvider());
builder.UseMySql(connectionString);
builder.UseLoggerFactory(loggerFactory);
builder.EnableSensitiveDataLogging();
}
public static void Configure(DbContextOptionsBuilder<SensorBrokerDbContext> builder, DbConnection connection)
{
var loggerFactory = new LoggerFactory();
loggerFactory.AddProvider(new EFLoggerProvider());
builder.UseMySql(connection);
builder.UseLoggerFactory(loggerFactory);
builder.EnableSensitiveDataLogging();
}
}
}
4.修改配置log4net.config
在log4net节点中增加如下配置
<appender name="EntityFrameworkCoreDatabaseCommandLogFile" type="log4net.Appender.RollingFileAppender" >
<file value="App_Data/Logs/EFLogs.txt" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="10000KB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%-5level %date [%-5.5thread] %-40.40logger - %message%newline" />
</layout>
</appender>
<logger name="SensorBroker.Log.EFCoreDatabaseCmdLog" additivity="false">
<level value="ALL"/>
<!--如果想增加日志输出目的地，增加<appender-ref>节点就是了，注意后面的ref是在config中配置的appender name-->
<appender-ref ref="EntityFrameworkCoreDatabaseCommandLogFile" />
</logger>
这样所有的数据库脚本日志都就会到EFLogs.txt中。
ABP增加记录EFCore 生成数据库脚本日志到新的txt文件
