As i know we can define pointcut even for an advice. example
package com.master_scrum.aop;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
#Aspect
public class ConstructorAspect {
#Before("execution(com.master_scrum.Account.new(..)")
public void beforeExecuteConstructor(JoinPoint jp){
System.out.println("Do somthing good");
}
}
now how i can create another advice for this advice? What is synctax?
i've tried with this one but does not work:
package com.master_scrum.aop;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
#Aspect
public class AspectOfConstructorAspect {
#Before("execution("* ConstructorAspect.*(..))") //aspects are in same package
public void beforeAspect(JoinPoint jp){
System.out.println("Before constructor advice");
}
}
Thanks
i found solution from AspectJ manual
just define pointcut like this
package com.master_scrum.aop;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
#Aspect
public class AspectOfConstructorAspect {
#Before("adviceexecution() && within(com.master_scrum.aop.ConstructorAspect)")
public void beforeAspect(JoinPoint jp){
System.out.println("Before constructor advice");
}
}

My requirement is to get the mobile numbers using Native Module for android?.
My specs:
1, React Native 0.68.0
2, node 17
Just putting here a function so that you can get an idea:
#Override
public void onReceive(final Context context, final Intent intent) {
String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
TelephonyManager telephony = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
telephony.listen(new PhoneStateListener() {
#Override
public void onCallStateChanged(int state, String phoneNumber) {
Log.d("RINGER_IID", phoneNumber);
onCustomCallStateChanged(context, state, phoneNumber);
}
}, PhoneStateListener.LISTEN_CALL_STATE);
}

Got through this. Hope this helps.
Hi i want to make very simple application that print an openweathermap.org API answer in console. I thought it should works, but when i'm going to an adress in my browser i've got Whitelabel Error Page and nothing in console. I've made two classes. Main:
package com.example.restTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpMethod;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;
import java.util.Arrays;
#SpringBootApplication
public class RestTemplateApplication {
public static void main(String[] args) {
SpringApplication.run(RestTemplateApplication.class, args);
}
#Bean
public RestTemplate getRestTemplate() {
return new RestTemplate();
}
}
and controller:
package com.example.restTemplate.Controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpMethod;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;
import java.util.Arrays;
#RestController
public class ConsumeWebService {
#Autowired
RestTemplate restTemplate;
#RequestMapping(value = "localhost:8080/weather")
public void printWeather() {
HttpHeaders headers = new HttpHeaders();
headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
HttpEntity<String> entity = new HttpEntity<String>(headers);
System.out.println(restTemplate.exchange("http://api.openweathermap.org/data/2.5/weather?q=London,uk&myAPIKey",
HttpMethod.GET, entity, String.class).getBody());
}
}
Of course i didn't put here my real key to API and i should to declared city and key in params, but i will think about it in future. For now i just want to get a simple output in console and wll be appreciated for your help.
Why do you put "localhost:8080/weather" as value?
Change from
#RequestMapping(value ="localhost:8080/weather")
To
#RequestMapping(value = "/weather")

I am facing issue in calling my java class methods (android native code) from JS.
I have already followed https://facebook.github.io/react-native/docs/native-modules-android.html but its not working. Please find below the issues which I am facing.
Where we should export android module, I have done it in index.js
import {NativeModules} from 'react-native';
const { ScannerInteractor } = NativeModules;
export default ScannerInteractor;
or
import {NativeModules} from 'react-native';
module.exports = NativeModules.ScannerInteractor;
In a javascript class where I want to call this method how should I import my class, I have written following code. Does it matter if index.js are at same level as of my javascript class?
import ScannerInteractor from "./ScannerInteractor"
I have created member methods then how to call them? As per example, it need to be call as static method call.
ScannerInteractor.startScan(this, null, null);
How to pass context variable from JS, will passing 'this' parameter will work?
I am not getting any error or log messages in the logcat but method is also not getting triggered.
NativeModule class
import com.facebook.react.ReactPackage;
import com.facebook.react.bridge.NativeModule;
import com.facebook.react.bridge.ReactApplicationContext;
import com.facebook.react.uimanager.ViewManager;
import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
import com.kohl.scan.common.ScannerInteractor;
public class ModuleInjector implements ReactPackage {
#Override
public List<ViewManager> createViewManagers(ReactApplicationContext reactContext) {
return Collections.emptyList();
}
#Override public List<NativeModule> createNativeModules(
ReactApplicationContext reactContext) {
List<NativeModule> modules = new ArrayList<>();
modules.add(new ScannerInteractor(reactContext));
return modules;
}
}
ApplicationClass
import com.facebook.react.ReactPackage;
import java.util.Arrays;
import java.util.List;
import com.lugg.ReactNativeConfig.ReactNativeConfigPackage;
import com.reactnativenavigation.NavigationApplication;
import com.oblador.vectoricons.VectorIconsPackage;
import com.rfpproject.ModuleInjector;
public class MainApplication extends NavigationApplication {
#Override
public boolean isDebug() {
// Make sure you are using BuildConfig from your own application
return BuildConfig.DEBUG;
}
protected List<ReactPackage> getPackages() {
// Add additional packages you require here
// No need to add RnnPackage and MainReactPackage
return Arrays.<ReactPackage>asList(
// eg. new VectorIconsPackage()
new ReactNativeConfigPackage(),
new VectorIconsPackage(),
new ModuleInjector()
);
}
#Override
public String getJSMainModuleName() {
return "index";
}
#Override
public List<ReactPackage> createAdditionalReactPackages() {
return getPackages();
}
}
I am calling it from JS script as mentioned below:
onClick1(){
ScannerInteractor.startScan(this, null, null);
//alert('cllllll');
}
It has worked after using
import {NativeModules} from 'react-native';
module.exports = NativeModules.ScannerInteractor;
and
import {NativeModules} from 'react-native'; in the JS class and calling using NativeModules.ScannerInteractor.check()
Still not clear about how to pass context variable as an argument.
I'm very new to OOP and Java. I came across this excellent video of page object factory on page object pattern:https://www.youtube.com/watch?v=u8XH46u1QAw. I tried to implement a similar code for a basic yahoo site and I get a Null pointer error. Can you please help me in troubleshooting this? I appreciate your time. My code is using testNG
Error from console:
FAILED: execute
java.lang.NullPointerException
at PageObject.SearchPage.updateSearch(SearchPage.java:16)
Code:
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.ie.InternetExplorerDriver;
import org.testng.annotations.AfterTest;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;
import PageObject.SearchPage;
public class PgMain {
WebDriver Browser;
#BeforeTest
public void start(){
Browser=new InternetExplorerDriver ();
}
#Test
public void execute(){
SearchPage s=new SearchPage(Browser);
s.navigateTo();
s.updateSearch();//This is when I get the NPE
}
#AfterTest
public void stop(){
}
}
package PageObject;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.support.PageFactory;
public abstract class Abs {
WebDriver Browser;
public Abs(WebDriver Browser){
this.Browser=Browser;
}
public SearchPage navigateTo(){
Browser.get("http://finance.yahoo.com/");
return PageFactory.initElements(Browser, SearchPage.class);
}
}
package PageObject;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.FindBy;
import org.openqa.selenium.support.PageFactory;
public class SearchPage extends Abs {
#FindBy (id="UHSearchProperty")
private WebElement searchFinancebtn;
#FindBy (id="UHSearchBox")
private WebElement usersearchBox;
public SearchPage(WebDriver Browser){
super(Browser);
}
public SearchPage updateSearch(){
usersearchBox.sendKeys("GOOG");//NPE
searchFinancebtn.click();
return PageFactory.initElements(Browser, SearchPage.class);
}
}
you initElements only on the returned instance of SearchPage during navigateTo() call.
so for your code to work you'd have to do the following:
SearchPage s = new SearchPage(Browser);
s.navigateTo().updateSearch();
but to be honest this looks very ugly. Why not just to do the following:
WebDriver driver;
SearchPage searchPage;
#Before
public void start() {
driver = new InternetExplorerDriver();
searchPage = PageFactory.initElements(driver, SearchPage.class);
}
#Test
public void execute() {
s.navigateTo();
s.updateSearch();
}
Also I'd question the excellence of that video.
