Abp6.0 使用 appsettings.json配置Serilog.Sinks.MariaDB

Abp6.0中已经启用Serilog,使用Serilog.Sinks.MariaDB包可以保存到MariaDB，mysql中

一种做法是在var loggerConfiguration = new LoggerConfiguration( )后使用WriteTo.MariaDB扩展方法来配置，这样在代码中配置不够灵活，修改起来也不方便

其实在Serilog.Sinks.MariaDB的github上很直接的提供了另外一种方式，通过配置文件来配置。这里需要使用*Serilog.Settings.Configuration*来读取配置文件。关于配置，其实是有默认配置形式的。短短几行代码就解决了问题，

//生成一个ConfigurationBuilder，把配置文件加进来
  var configuration = new ConfigurationBuilder()
  .SetBasePath(Directory.GetCurrentDirectory())
  .AddJsonFile("appsettings.json")
  .AddJsonFile($"appsettings.{Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT") ?? "Production"}.json", true)
  .Build();

  var loggerConfiguration = new LoggerConfiguration( )
      .ReadFrom.Configuration(configuration)//从文件中读取配置

配置文件的格式如下,具体含义请找官方文档：

  "Serilog": {
    "Using": [
      "Serilog.Sinks.MariaDB"
    ],
    "MinimumLevel": "Debug",
    "WriteTo": [
      {
        "Name": "MariaDB",
        "Args": {
          "connectionString": "Server=192.168.1.1;Port=12345;Database=xxxx;Uid=xxx;Pwd=xxxxxxxxx;",
          "autoCreateTable": true,
          "tableName": "Logs",
          "restrictedToMinimumLevel": "Warning",
          "batchPostingLimit": 1000,
          "period": "0.00:00:30",
          "options": {
            "PropertiesToColumnsMapping": {
              "Exception": "Exception",
              "Level": "Level",
              "Message": "Message",
              "MessageTemplate": "MessageTemplate",
              "Properties": "Properties",
              "Timestamp": "Timestamp"
            },
            "TimestampInUtc": true,
            "ExcludePropertiesWithDedicatedColumn": true,
            "EnumsAsInts": true,
            "LogRecordsCleanupFrequency": "0.02:00:00",
            "LogRecordsExpiration": "31.00:00:00"
          }
        }
      }
    ]
  }
