2016年8月2日 · For an explanation about context in programming terms, have a look at this answer. The JAX-RS API provides a @Context annotation. In general, such annotation can be used to obtain contextual Java types related to the request or response. Those types can be injected into classes managed by the JAX-RS runtime.

2017年8月16日 · A context is an ordered sequence of properties that define an environment for the objects resident inside it. Contexts get created during the activation process for objects that are configured to require certain automatic services, such as synchronization, transactions, just-in-time activation, security, and so on.

public Task Invoke(HttpContext context) { // Do something with the current HTTP context... } HTTP context accessor. Finally, you can use the IHttpContextAccessor helper service to get the HTTP context in any class that is managed by the ASP.NET Core dependency injection system. This is useful when you have a common service that is used by your ...

2017年3月31日 · 3) If using Entity Framework add a database context service (MyDbContext is the context class generated by EF). You also want to tell the built-in dependency injection how to instantiate your database context: services.AddDbContext<MyDbContext>(options => options.UseSqlServer(connection)); services.AddScoped<IMyDbContext, MyDbContext>();

@RakaAdiNugroho I found out that I used a wrong place for getting context: firstly I wrote <code>val context = +ambient(ContextAmbient)<code> inside Clickable and it was the reason of that exception. Then I put this line out of the Clickable to the head of the function and everything became Ok. My fault.

2010年8月26日 · The context allows multiple instances of the system to coexist in a single process, each with its own context. later in the comment section, you will find another comment by bjornw. If you just grep a codebase you'll see hundreds of different getContext, getBaseContext, getBlaBlaContext. He is also right.

2018年6月11日 · Okay, this means; you don't create a context, you ask the framework to give you one, based on some rules you defined before. Example: somewhere you will register your dbcontext, (Startup.cs): //typical configuration part of .net core public void ConfigureServices(IServiceCollection services) { //some mvc services.AddMvc(); //hey, options!

2015年4月13日 · your context type (here: ContextType.Domain) the domain name (try just the "Netbios" name, e.g. "YOURDOMAIN" - or leave NULL for "default" domain) optionally a container (as an LDAP path - a "distinguished" name, full path but without any LDAP:// prefix) So try something like this:

This changeover to CDI could possibly happen in 2 steps; in JAX-RS 2.2 everything that can now be injected by @Context should also be injectable using @Inject and JAX-RS resources would be CDI beans by default (perhaps unless explicitly disabled). At the same time @Context would be deprecated. In JAX-RS 3.0 @Context would then be actually removed.
