XYS.Utils.Log4Net

基于 log4net 的日志工具类库：按 前缀 + 级别 分离日志输出，支持自动捕获调用方法名、异常记录与格式化日志。

配置

程序集在加载时通过特性自动读取 log4net 配置：

[assembly: log4net.Config.XmlConfigurator(ConfigFile = "xys.log4net.config.xml", Watch = true)]
  • 配置文件名固定为 xys.log4net.config.xml，需放在应用程序运行目录下（相对基目录解析）。
  • Watch = true：运行时修改配置会被自动重新加载。
  • 静默失败：若配置文件缺失或未定义 appender，log4net 不会报错，而是不产生任何日志输出。部署时请确认该文件已随程序一同发布。

logger 命名规则

每条日志按 {前缀}{级别后缀} 解析 logger，后缀为 -Debug / -Info / -Warn / -Error / -Fatal。例如前缀传 Order，Error 级别日志会写入名为 Order-Error 的 logger。可在配置中按此命名把不同来源、不同级别的日志分流到不同文件。

LogUtil

静态日志工具类，命名空间 XYS.Utils.Log4Net。提供 Debug / Info / Warn / Error / Fatal 五个级别，每级均含普通、含异常、格式化三类重载。

using XYS.Utils.Log4Net;

// 最简：仅传前缀与内容，方法名由 [CallerMemberName] 自动填充
LogUtil.Info("Order", "订单创建成功");

// 记录异常
try { /* ... */ }
catch (Exception ex)
{
    LogUtil.Error("Order", "订单创建失败", ex);
}

// 显式指定类型名 / 方法名
LogUtil.Warn("Order", nameof(OrderService), "Create", "库存不足");

// 格式化日志
LogUtil.InfoFormat("Order", nameof(OrderService), "Create", "订单 {0} 金额 {1}", orderId, amount);

// 格式化 + 异常
LogUtil.ErrorFormat("Order", nameof(OrderService), "Create", "订单 {0} 处理失败", ex, orderId);

日志正文格式为：类型名(左对齐32) 方法名(左对齐24)-内容，便于日志按列对齐阅读。

健壮性

日志记录不会因参数问题打断业务调用方：

  • typeName / methodName 为 null 时按空串处理，不抛 NullReferenceException。
  • *Format 系列在格式串与参数不匹配时捕获 FormatException，退化为输出原始格式串，不向上抛出。
  • 各级别在写入前先判断 IsXxxEnabled，未启用的级别直接短路，避免无谓的字符串拼接与格式化开销。
