Angular first site visit non-root path works locally but not in production

阅读更多关于 Angular first site visit non-root path works locally but not in production

问题 In my Angular 4 application, if I type a non-root path into the url as my first visit to the site (i.e. localhost:4200/projects ), my application is bootstrapped and the correct component is rendered to the screen in the browser. However, once I serve the site through IIS, if I go to http://<my-domain>.com/projects , I get a 404 error (not from my application) and the application is never bootstrapped. How do I get a visit to a non-root path as the first visit to the site in production to

@angular/platform-browser vs. @angular/platform-browser-dynamic

阅读更多关于 @angular/platform-browser vs. @angular/platform-browser-dynamic

In the newer examples (seeds, angular.io,..) there is an another import for the bootstrapping process: @angular/platform-browser-dynamic . Could someone explain, what are the differences between it and @angular/platform-browser ? There is no information on the official angular.io website yet. himadri If you look closely at the history of the angular2 then you will find there are two version 1) beta version 2) release candidate version. At present it is r.c 3 (release candidate 3). Release candidate version means bug fix releases before the final release. So when angular2 moves to first release

Spring startup performance issues

阅读更多关于 Spring startup performance issues

I'm trying to integrate Spring in a pretty large application with thousands of classes, and i'm experiencing huge delays starting my container because of component-scanning. I have already narrowed the number of directories specified in the "base-package", to the minimum in order to reduce the time wasted in scanning irrelevant directories, but the class-path scanning part of initialization still takes about 1-2 mins. So, is there a way to optimize the scanning process ? I've thought of storing the candidate classes path in a file and make the container then get them from the file instead of

Grails: Accessing spring beans in the destory closure of Bootstrap code?

阅读更多关于 Grails: Accessing spring beans in the destory closure of Bootstrap code?

问题 I'm looking to access a bean in my destroy closure in the Bootstrap.groovy of my grails project. Any ideas on how to achieve this? I seem to have no access to servletContext...? 回答1: You can obtain a a reference to the applicationContext from everywhere (including the destroy closure of BootStrap) using that chunk of code: def ctx = org.codehaus.groovy.grails.web.context.ServletContextHolder.servletContext.getAttribute(org.codehaus.groovy.grails.web.servlet.GrailsApplicationAttributes

re-open and add dependencies to an already bootstrapped application

阅读更多关于 re-open and add dependencies to an already bootstrapped application

Is there a way to inject a late dependency to an already bootstrapped angular module? Here's what I mean: Say that I have a site-wide angular app, defined as: // in app.js var App = angular.module("App", []); And in every page: <html ng-app="App"> Later on, I'm reopening the app to add logic based on the needs of the current page: // in reports.js var App = angular.module("App") App.controller("ReportsController", ['$scope', function($scope) { // .. reports controller code }]) Now, say that one of those on-demand bits of logic also requires their own dependencies (like ngTouch , ngAnimate ,

问题 I'm writing a bootstrap and kernel for myself and both bootstrap and kernel will be burn on a CD-R and will function as a CD-live. It is not a linux CD-Live or something else,is totally my own bootloader and kernel. I do not want to use other booloaders (i.e. GRUB) so please don't suggest me to use them. Here is my question: In my bootloader ASM code, I want to load my kernel and kernel entry into the RAM from CD-ROM (not from hard disk or floppy disk), and lets assume that we know where the

Couldn't register […] with the bootstrap server

阅读更多关于 Couldn't register […] with the bootstrap server

I keep getting this error when launching my app on the iOS Simulator: Couldn't register com.mycompany.MyApp with the bootstrap server. Error: unknown error code. This generally means that another instance of this process was already running or is hung in the debugger. I've read other reports of this error and it seems there is no obvious fix for it (restarting the iOS Simulator, restarting Xcode etc..) At this point here's a list of things I've tried: Restarting the Simulator Restarting Xcode Rebooting my machine Deleting my app's Derived Data, and Cleaning Deleting the iOS Simulator App

How can a JVM be written in Java

阅读更多关于 How can a JVM be written in Java

问题 I was briefly reading about Maxine which is an open source JVM implementation that written in Java. This sounds circular to me. If java requires a virtual machine to run in, how can the virtual machine itself be written in Java (won't the VM code require a VM in which to run, and so on?). Edit : Ok, so I see I overlooked the fact that Java doesn't have to run in a VM. How then does one explain how a LISP compiler can be written in LISP? Or should this be a new question altogether? 回答1: Your

Recipe for compiling binutils & gcc together?

阅读更多关于 Recipe for compiling binutils & gcc together?

问题 According the the gcc build instructions you can build binutils concurrently with building gcc (as well as gmp,mpc,etc). Here's what that page says : If you also intend to build binutils (either to upgrade an existing installation or for use in place of the corresponding tools of your OS), unpack the binutils distribution either in the same directory or a separate one. In the latter case, add symbolic links to any components of the binutils you intend to build alongside the compiler (bfd,

What is Erlang written in?

问题 What is Ericsson's implementation of Erlang and Erlang/OTP written and compiled in? Is is assembly, C or Erlang itself? Update 1: Thanks to DrJokepu. If I understand correctly, Erlang source-to-VM compiler is written in Erlang itself. But the VM is written in C. Update 2: Hynek-Pichi-Vychodil pointed out a lot of details. VM and HW interacting drivers: in C. Compiler (to VM) and libraries: in Erlang. Extensions: Possible in any language by writing a port or an Erlang node in that language.
