配置管理

所属模块：架构概览

---

1. 配置文件结构

// Configuration/appsettings.json
{
  "Database": {
    "Type": "sqlite",
    "Path": "./data/database/wctminer.db"
  },
  "Parser": {
    "BatchSize": 1000
  },
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "WCTDataMiner": "Debug"
    }
  },
  "Paths": {
    "LogDir": "./data/logs",
    "OutputDir": "./data/output"
  }
}

---

2. 配置类定义

// Configuration/AppSettings.cs
namespace WCTDataMiner.Configuration;

public class AppSettings
{
    public DatabaseSettings Database { get; set; } = new();
    public ParserSettings Parser { get; set; } = new();
    public PathSettings Paths { get; set; } = new();
}

public class DatabaseSettings
{
    public string Type { get; set; } = "sqlite";
    public string Path { get; set; } = "./data/database/wctminer.db";
    
    // PostgreSQL 配置（可选）
    public string? Host { get; set; }
    public int Port { get; set; } = 5432;
    public string? Name { get; set; }
    public string? User { get; set; }
    public string? Password { get; set; }
}

public class ParserSettings
{
    public int BatchSize { get; set; } = 1000;
}

public class PathSettings
{
    public string LogDir { get; set; } = "./data/logs";
    public string OutputDir { get; set; } = "./data/output";
}

3. 配置加载

// Program.cs 配置加载部分
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using WCTDataMiner.Configuration;

var builder = Host.CreateDefaultBuilder(args);

builder.ConfigureAppConfiguration(config =>
{
    config.AddJsonFile("appsettings.json", optional: false);
    config.AddJsonFile($"appsettings.{environment}.json", optional: true);
    config.AddEnvironmentVariables();
    config.AddCommandLine(args);
});

builder.ConfigureServices((context, services) =>
{
    services.Configure<AppSettings>(context.Configuration.GetSection(""));
    
    // 注册数据库服务
    services.AddDatabaseServices(context.Configuration);
    
    // 注册其他服务
    services.AddScoped<QfodParser>();
    services.AddScoped<PlossParser>();
    services.AddScoped<ParseService>();
    services.AddScoped<ErrorHandlingService>();
});
