过滤日志

日志可以通过以下方式进行筛选：

  • LogCategory
  • LoggingProvider

appsettings.json 中指定类的 LogLevel：

  1.   "Logging": {
  2.     "LogLevel": {
  3.       "Default": "Warning",
  4.       "StudentManagement.Controllers.HomeController": "Trace",
  5.       "StudentManagement.Models.SQLStudentRepository": "Error",
  6.       "Microsoft": "Information"
  7.     }
  8.   }

给 Debug 界面指定 LogLevel：

  1.   "Logging": {
  2.     "Debug": {
  3.       "LogLevel": {
  4.         "Default": "Warning",
  5.         "StudentManagement.Controllers.HomeController": "Warning",
  6.         "StudentManagement.Models.SQLStudentRepository": "Warning",
  7.         "Microsoft": "Warning"
  8.       }
  9.     },
  10.     "LogLevel": {
  11.       "Default": "Trace",
  12.       "StudentManagement.Controllers.HomeController": "Trace",
  13.       "StudentManagement.Models.SQLStudentRepository": "Trace",
  14.       "Microsoft": "Trace"
  15.     }
  16.   }
