本文介绍了在调试Autofac依赖注入的作品,但在发行崩溃的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
什么会导致我的DI在发布模式崩溃时,在调试模式下的罚款?这是一个Xamarin.Forms的应用程序,并正在运行在Android

我构造的一个例子是这样的。
公开的MainPage(Func键<作用,动作<布尔型>中的MainMenu> MAINMENU,
ModulePage modulePage,
loadingPage loadingPage,
Func键<作用, authPage> authPage,
IUserDialogService userDialogService,
IModuleService moduleService,

{
_loadingPage = loadingPage;
_authPage = authPage;
_userDialogService = userDialogService;
_moduleService = moduleService;
_syncCommand = syncCommand;

VAR主= MAINMENU(OnAfterDeauthenticated,OnToggleRequest());
变种细节=新NavigationPage(modulePage);
如果(App.Navigation == NULL)
{
App.Navigation = detail.Navigation;
}

细节=细节;
}
的
ContainerBuilder获取Android应用程序初始化,然后传递给PCL。
的Android
保护覆盖无效的OnCreate(束束)

解决方案
好了,解决的办法很简单。但不必要IMO
我打开所有的 Func键<>
注射用实际的工厂
私人FooPageFactory _fooPage
公共SomePage的(FooPageFactory fooPage)
{
_fooPage = fooPage;在需要的时候
//
_fooPage.Init(SomeActionDependency);
}
What would cause my DI to crash in Release mode when it's fine in Debug mode? This is a Xamarin.Forms app, and is being run on Android.

The program 'Mono' has exited with code 0 (0x0).
An example of my constructor is this
public MainPage(Func<Action, Action<bool?>, MainMenu> mainMenu,
ModulePage modulePage,
LoadingPage loadingPage,
Func<Action, AuthPage> authPage,
IUserDialogService userDialogService,
IModuleService moduleService,
ISyncCommand syncCommand)
{
_loadingPage = loadingPage;
_authPage = authPage;
_userDialogService = userDialogService;
_moduleService = moduleService;
_syncCommand = syncCommand;
Title = Strings.app_title;
var master = mainMenu(OnAfterDeauthenticated, OnToggleRequest());
var detail = new NavigationPage(modulePage);
if (App.Navigation == null)
{
App.Navigation = detail.Navigation;
}
Master = master;
Detail = detail;
}
The ContainerBuilder gets initialized in the Android App, and then passed to the PCL.
Android
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
Forms.Init(this, bundle);
var container = RegisterDependencies();
var page = App.GetMainPage(container);
SetPage(page);
}
private static IContainer RegisterDependencies()
{
var containerBuilder = new ContainerBuilder();
RegisterAndroidSpecific(containerBuilder);
var coreIoc = new CoreIoC(containerBuilder);
return coreIoc.Load();
}
private static void RegisterAndroidSpecific(ContainerBuilder containerBuilder)
{
containerBuilder.RegisterType<AudioPlayer>().SingleInstance().As<IAudioPlayer>();
containerBuilder.RegisterType<SettingsService>().As<ISettingsService>();
containerBuilder.RegisterType<NetworkService>().As<INetworkService>();
containerBuilder.RegisterType<NativeVideoPlayer>().As<IVideoPlayer>();
containerBuilder.RegisterType<MarkdownService>().As<IMarkdownService>();
containerBuilder.RegisterType<UserDialogService>().As<IUserDialogService>();
containerBuilder.RegisterType<DbProvider>()
.SingleInstance()
.WithParameters(new List<Parameter> {
new TypedParameter(typeof(string), "fsm-breathingroom"),
new TypedParameter(typeof(SqliteSettings), new SqliteSettings {
CacheSize = 16777216,
SyncMode = SynchronizationModes.Off,
JournalMode = SQLiteJournalModeEnum.Off,
PageSize = 65536
})
})
.As<IDbProvider>();
}
PCL
public static Page GetMainPage(IContainer container)
{
Container = container;
RegisterCurrentUser(Container.Resolve<UserModel>());
RunMigrations();
RegisterCurrentUser();
var rootPage = Container.Resolve<MainPage>();
return rootPage;
}
解决方案
Well, the solution was easy but unnecessary IMO.
I switched all the Func<>
injections with actual factories.
private FooPageFactory _fooPage
public SomePage(FooPageFactory fooPage)
{
_fooPage = fooPage;
// when needed
_fooPage.Init(SomeActionDependency);
}
