I try to create sird Router in Play Framework (from official tutorial https://www.playframework.com/documentation/2.6.x/ScalaSirdRouter#Binding-sird-Router).
I created the same structure and files but I get error after compile "Compilation error value withPrefix is not a member of api.ApiRouter".
ApiRouter (from official tutorial):
package api
import javax.inject.{Inject, Singleton}
import play.api.routing.Router.Routes
import play.api.routing.SimpleRouter
import play.api.routing.sird._
class ApiRouter #Inject()(controller: controllers.ApiController) extends SimpleRouter {
override def routes: Routes = {
case POST(p"/") => controller.message("test")
}
}
ApiController works, routes file has error "cannot resolve api.ApiRouter" in
-> /api api.ApiRouter
I tried to change path and namespace in ApiRoter file (file put in app/controllers, namespace change to "controllers" and change to "controllers.ApiController" in routes line) but the same error.
Where did I mistake?

I'm helping my development team with some logging code in our framework.
using spring AOP I've created a groovy class called LoggingAspect. Its main purpose is to log method execution times for classes in com.zions.comon.services.logging directories and
annotated with #Loggable.
Since some classes already have #sl4j logging I need to detect if hat log member objects exists and use the built in #slf4j logging for that class. If it doesn't I need to execute the #sl4j annotation in aspect logging code.
The first statement in the try block will check if log member exists on object. If it does, then iLog will get set to incoming object's logger. However I'm not sure how to complete the rest of the code Once I detect the log member object. I don't expect anyone to write this code for me but would appreciate any suggestions/areas of researcoh on how to do this - such as using "if"
The logic should go something like:
Intercept and calculate method logging times in select classes
Check for existing log member object that indicates #slf4j is already present in class
If log member object exits use #sl4j logging features already built into that class
If log member object doesnt exist use #slf4j logging in logging Aspect code.
any help would be appreciated

Reverted code to original version - My LoggingAspect code looks like this at the moment
package com.zions.common.services.logging
import groovy.util.logging.Slf4j
import org.slf4j.Logger
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.springframework.context.annotation.Configuration
import org.springframework.context.annotation.EnableAspectJAutoProxy
#Aspect
#Configuration
#Slf4j
#EnableAspectJAutoProxy(proxyTargetClass=true)
public class LoggingAspect {
*
* This is a Logging Aspect for the Loggable annotation that calculates method runtimes
* for all methods under classes annotated with #Loggable*/
/**
* Logs execution time of method under aspect.
*
* #param joinPoint - method under join
* #return actual return of method under join point.
* #throws Throwable
*/
#Around('execution (* *(..)) && !execution(* *.getMetaClass()) && #within(com.zions.common.services.logging.Loggable)')
public Object logExecutionTime(ProceedingJoinPoint joinPoint) throws Throwable {
def obj = joinPoint.this
Logger iLog = log
long start = System.currentTimeMillis();
Object proceed = joinPoint.proceed();
long executionTime = System.currentTimeMillis() - start;
try {
/*First statement of try block attempts to test if log members exist on object.
If it does, then iLog will get set to incoming object's logger*/
obj.log.isInfoEnabled()
iLog = obj.log
} catch (e) {}
iLog.info("${joinPoint.getSignature()} executed in ${executionTime}ms");
return proceed;
}
}
If its helpful my logging Annotation is
package com.zions.common.services.logging
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
/* Logging annotation to be used at class level
* Loggable annotation for all methods of a class annotated with the #Loggable annotation*/
#Target(ElementType.TYPE)
#Retention(RetentionPolicy.RUNTIME)
public #interface Loggable {}
I've added a junit test class that validates when log member is found - The line 'iLog = obj.log' get's called from the LoggingAspect code and the test is PASSING.
LoggingAspectSpecification.groovy
package com.zions.common.services.logging
import static org.junit.Assert.*
import groovy.util.logging.Slf4j
import org.junit.Test
import org.springframework.beans.factory.annotation.Autowired
import org.springframework.boot.test.context.TestConfiguration
import org.springframework.context.annotation.Bean
import org.springframework.context.annotation.ComponentScan
import org.springframework.context.annotation.Profile
import org.springframework.context.annotation.PropertySource
import org.springframework.test.context.ContextConfiguration
import spock.lang.Specification
#ContextConfiguration(classes=[LoggingAspectSpecificationConfig])
class LoggingAspectSpecification extends Specification {
#Autowired
SomeClass someClass
def 'Main flow for timing log'() {
setup: 'class to be logged'
when: 'execute something with class testing log'
someClass.methodOne()
someClass.methodTwo()
then: 'validate something logged'
true
}
}
#TestConfiguration
#Profile("test")
#ComponentScan(["com.zions.common.services.logging"])
#PropertySource("classpath:test.properties")
class LoggingAspectSpecificationConfig {
#Bean
SomeClass someClass() {
return new SomeClass()
}
}
#Loggable
#Slf4j
class SomeClass {
def methodOne() {
log.info('run methodOne')
}
def methodTwo() {
log.info('run methodTwo')
}
}
However my unit test is failing with classes that do not have #Slf4j meaning it will execute with the logger of the aspect instead of the pointcut object. The full error trace is:

The second unit test code is below - (the only difference is that #Slf4j) is not present in the classes.
LoggingAspectSpecification2.groovy
package com.zions.common.services.logging
import static org.junit.Assert.*
import groovy.util.logging.Log
import groovy.util.logging.Slf4j
import org.junit.Test
import org.springframework.beans.factory.annotation.Autowired

import spock.lang.Specification
#ContextConfiguration(classes=[LoggingAspectSpecificationConfig2])
class LoggingAspectSpecification2 extends Specification {
#Autowired
SomeClass2 someClass2
def 'Main flow for timing log'() {
setup: 'class to be logged'
when: 'execute something with class testing log'
someClass2.methodOne()
someClass2.methodTwo()
then: 'validate something logged'
true
}
}
<!-- language: lang-groovy -->
#TestConfiguration
#Profile("test")
#ComponentScan(["com.zions.common.services.logging"])
#PropertySource("classpath:test.properties")
class LoggingAspectSpecificationConfig2 {
#Bean
SomeClass2 someClass2() {
return new SomeClass2()
}
}
<!-- language: lang-groovy -->
#Loggable
class SomeClass2 {
def methodOne() {
int x=10, y=20;
System.out.println(x+y+" testing the aspect logging code");
}
def methodTwo() {
int x=10, y=20;
System.out.println(x+y+" testing the aspect logging code");
}
}
I'm guessing something's wrong in my LoggingAspect code in the Try Catch block?
To resolve the error and get my unit test to pass without #Slf4j or #Log - I had to add a println statement to the SomeClass2 code as in,
int x=10, y=20;
System.out.println(x+y+" testing the apsect logging code");
adding #Log just gave it another built in log member similar to #Slf4j - adding the println statement and removing the #Log annotation force the LoggingAspect code to execute. Unit test is passing.
I am currently attempting to return an observable from a service in Angular2. If you look at the following code, if I uncomment the line in the constructor, everything works fine, and the consumer of the service won't break. But when I try to remove the call from the constructor, it crashes with:
Error: XHR error (404 Not Found) loading http://localhost:3847/rxjs/observable
I believe that it is trying to subscribe to the todo$ property prior to initialisation. So how can I create an initial observer that doesn't actually make the call to the get method straight away? That is, I need some sort of empty Observer that will stop the subscribe line from falling over.
How am I supposed to achieve this?
Tony
import {Injectable} from 'angular2/core';
import {Http} from 'angular2/http';
import {Todo} from './todo';
import {Observable} from 'rxjs/observable'
#Injectable()
export class TodoService {
public todos$: Observable<Todo[]>;
constructor(private http: Http) {
//this.todos$ = this.http.get('api/Todo').map(res => <Array<Todo>>res.json());
}
loadData() {
this.todos$ = this.http.get('api/Todo').map(res => <Array<Todo>>res.json());
}
}
import {Observable} from 'rxjs/observable'
should be
import {Observable} from 'rxjs/Observable';

I'm trying out Haxe programming and OpenFL library with Flashdevelop as the IDE. I made a package for my global game classes and then tried to import it, it just says the class I'm importing doesn't exist. Shouldn't it notice that I have the class in a source file under the Source directory?
Here is the Source/Main.hx file:
package;
import flash.display.Sprite;
import flash.display.BitmapData;
import flash.display.Bitmap;
import flash.events.MouseEvent;
import flash.text.TextField;
import flash.text.TextFormat;
import flash.text.Font;
import openfl.Assets;
import globals.Room;
class Main extends Sprite {
public function new () {
super ();
}
}
And here is the Source/Globals.hx file:
package globals;
public class Room {
public function new() {
}
}
Classes in the package this.is.a.package should be in the folder [source]/this/is/a/package so you should probably make a Room.hx file in Source/globals/
Also, FlashDevelop can make the class in the right folder if you define the package when you create it with the "Add -> New Class" menu (right click on your project)
When I call init() I get an error saying the class "Facebook" has not been declared. Every tutorial online has similar code and supposedly works so I'm guessing its a setting somewhere I haven't set because it does look like its getting imported.
My Code:
import flash.display.MovieClip;
import com.facebook.graph.Facebook;
import com.facebook.graph.net.*;
import com.facebook.graph.data.*;
public class A_CLASS extends MovieClip {
protected var _appID:String = "164534125383085";
function A_CLASS():void {
Facebook.init(_appID, logIn);
}
function logIn(session:Object, fail:Object):void {
console.text = "Did Init()";
}
}
My Output:
ReferenceError: Error #1065: Variable com.facebook.graph::Facebook is not defined.
at ALPHA_CLASS()[C:\Users\DelphPC\Desktop\FlashProjects\A\A_CLASS.as:11]

that means your program cannot see the reference class please check your Build Path SWC or ANE and build your project then retry
I try to get the titles and URLs from a public Picasa album. But I am stuck at the very beginning: I cannot create a new PicasawebService.
My Code:

public List<Avatar> getPhotoURLs() throws Exception {
PicasawebService myService = new PicasawebService("HI");
myService.setUserCredentials("foo#gmail.com", "mypassword");
ArrayList<Avatar> rl = new ArrayList<Avatar>();
URL feedUrl = new URL("https://picasaweb.google.com/111420671758947023853/EWA2012");
System.out.println("dddddddddddddddddd");
AlbumFeed feed = myService.getFeed(feedUrl, AlbumFeed.class);
for (PhotoEntry photo : feed.getPhotoEntries()) {
Avatar a1 = new Avatar();
a1.setDescription(photo.getTitle().getPlainText());
a1.setUrl(photo.getMediaThumbnails().get(0).getUrl());
rl.add(a1);
}
return (rl);
}
}
The Error Message:

test.java is my test class with the public static void main method,
Avatar is a class with two variables: description and url, there are getters and setters for both
in my netbeans IDE line 27 of the PicasaManager.java file is: PicasawebService myService = new PicasawebService("HI");
the implemented interace only defines the getPhotoURLs() method
I have no idea how to solve this problem, i hope somebody here can help me.
Have you included gdata-core-1.0.jar and guava-12.0.jar? Good luck on the rest of Web Engineering UE4 ;-)
