ABP Vnext 引入外部JSON配置文件（AddJsonFile）的方法。
包括ABP通過JSON配置文件進行動態注入依賴
public class WPFAppModule : AbpModule
{
public override void ConfigureServices(ServiceConfigurationContext context)
{
var configuration = BuildConfiguration();
//var configuration = context.Services.GetConfiguration();
context.Services.AddFromConfigurationFile(configuration.GetSection("Services"));
}
private static IConfigurationRoot BuildConfiguration()
{
return new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile("configuration.json", optional: true, reloadOnChange: true)
//.AddJsonFile("autofac.json", optional: false, reloadOnChange: true)
.Build();
}
}
//configuration.json文件
{
//描述："實現類命名空間+實現類名稱,所在程序集名稱"
