+# DMS日志服务使用说明
+
+## 概述
+
+DMS项目现在支持Microsoft.Extensions.Logging.ILogger接口的日志服务:
+1. NLogLogger类直接实现Microsoft.Extensions.Logging.ILogger接口(位于DMS.WPF项目中)
+2. 提供ILoggerFactory用于创建命名的Logger实例(位于DMS.WPF项目中)
+
+## 如何注册日志服务
+
+在`Startup.cs`或程序的依赖注入配置中,使用以下扩展方法注册日志服务:
+
+```csharp
+using DMS.Application;
+
+// 在ConfigureServices方法中
+services.AddDmsServices();
+```
+
+这将注册以下服务:
+- `Microsoft.Extensions.Logging.ILogger` 接口及其实现 `NLogLogger`(单例,位于DMS.WPF.Logging命名空间)
+- `Microsoft.Extensions.Logging.ILoggerFactory` 接口及其实现 `NLogLoggerFactory`(单例,位于DMS.WPF.Logging命名空间)
+
+## 如何使用日志服务
+
+### 1. 使用构造函数注入ILogger(推荐)
+
+```csharp
+using Microsoft.Extensions.Logging;
+
+public class MyService
+{
+ private readonly ILogger _logger;
+
+ public MyService(ILogger logger)
+ {
+ _logger = logger;
+ }
+
+ public void DoSomething()
+ {
+ _logger.LogInformation("正在执行操作...");
+
+ try
+ {
+ // 业务逻辑
+ }
+ catch (Exception ex)
+ {
+ _logger.LogError(ex, "操作失败");
+ }
+ }
+}
+```
+
+### 2. 使用ILoggerFactory创建命名的Logger
+
+```csharp
+using Microsoft.Extensions.Logging;
+
+public class MyService
+{
+ private readonly ILogger _logger;
+
+ public MyService(ILoggerFactory loggerFactory)
+ {
+ _logger = loggerFactory.CreateLogger("MyService");
+ }
+
+ public void DoSomething()
+ {
+ _logger.LogInformation("正在执行操作...");
+
+ try
+ {
+ // 业务逻辑
+ }
+ catch (Exception ex)
+ {
+ _logger.LogError(ex, "操作失败");
+ }
+ }
+}
+```
+
+## NLogLoggerFactory的作用
+
+`NLogLoggerFactory`是`ILoggerFactory`接口的实现,主要作用是:
+
+1. **创建命名的Logger实例**:通过`CreateLogger(string categoryName)`方法,可以为不同的类或模块创建具有特定名称的Logger实例
+2. **支持依赖注入**:作为服务注册后,其他类可以通过构造函数注入`ILoggerFactory`来创建Logger实例
+3. **符合标准**:实现Microsoft.Extensions.Logging标准,确保与其他.NET日志组件兼容
+
+## 日志级别映射
+
+Microsoft.Extensions.Logging与NLog之间的日志级别映射如下:
+
+| Microsoft.Extensions.Logging | NLog |
+|-----------------------------|----------|
+| Trace | Trace |
+| Debug | Debug |
+| Information | Info |
+| Warning | Warn |
+| Error | Error |
+| Critical | Fatal |
+
+## 节流功能
+
+NLogLogger提供了节流功能,以防止在短时间内产生大量重复的日志(日志风暴)。默认情况下,所有日志都会启用节流,节流时间窗口为30秒。
+
+## 配置
+
+NLog的配置文件位于 `DMS.Core\Configurations\nlog.config`,可以根据需要进行修改。
