    मेरे पास वसंत सेम नीचे है। 

      सार्वजनिक वर्ग कर्मचारी 2 {निजी इंट आईडी; निजी स्ट्रिंग का नाम; निजी डबल वेतन; सार्वजनिक कर्मचारी 2 (इंट आईडी, स्ट्रिंग का नाम, डबल वेतन) {this.id = id; This.name = name; इस.salary = वेतन;   
     अब मैं स्प्रिंग कॉन्फ़िगरेशन फ़ाइल में कॉन्फ़िग के नीचे है।  
      & lt; bean id = "emp2 "वर्ग =" com.basic.Employee2 "& gt; & Lt; constructor-arg नाम = "id" मान = "" / & gt; & Lt; constructor-arg नाम = "नाम" मान = "" / & gt; & Lt; कन्स्ट्रक्टर- आर्ग नाम = "वेतन" मान = "" / & gt; & Lt; / सेम ​​& gt;   
     अब मैं गतिशील कोड से ऊपर के रूप में मानों को नहीं मान सकता।  
     अब मैं स्प्रिंग बीन प्रोग्रामाइम नीचे कोड का उपयोग कर रहा हूं।  बीन स्कोप सिंगलटन  है।  
      कर्मचारी 2 एएमपी = (कर्मचारी 2) applicationContext.getBean ("emp2");   
       
       
     Div class = "post-text" itemprop = "text"> 
     आप विधि का उपयोग कर सकते हैं, जो  
     
     स्पष्ट कन्स्ट्रक्टर तर्क / फ़ैक्टरी विधि तर्क निर्दिष्ट करने देता है, निर्दिष्ट डिफ़ॉल्ट तर्क को ओवरराइड करता है (यदि कोई है) बीन की परिभाषा में।   
     उदाहरण के लिए:  
      पूर्णांक param1 = 2; स्ट्रिंग param2 = "test"; डबल परम 3 = 3.4; कर्मचारी 2 एएमपी = (कर्मचारी 2) applicationContext.getBean ("emp2", परम 1, परम 2, परम 3);   
     वैसे भी, जब यह संभवतः काम करेगा, आपको  Spring EL  का उपयोग करने पर विचार करना चाहिए, जैसा कि प्रश्न के तहत एक टिप्पणी में उल्लिखित है।

Android - Facebook GraphUser has no email attribute -

I checked online sources about this issue and checked it twice - but I still get the email attribute Can not Facebook Response As indicated on the launch, I have applied the permissions ("original_third", "email", "user_bridade") to read on the login buttons. Also set the same permissions when creating a session (session .createFromExistingAccessToken). However, on the callback function, when the GraphUser and Response object is logged, I was still not able to retrieve the user's email. Why the error still persists, what are the possible reasons for this? Am I missing some steps? ** onCreate () ** ((Login button) ViewById (R.id.dialog_generic_footer_button_fblogin)) .setPublishPermissions (FBSessionV2.getPermissions ()); String & gt; GetPermissions () {if (permissions.ISTT)} {PERMISSIONS.add ("basic_info"); PERMISSIONS.add ("email"); PERMISSIONS.add ("publish_actions"); PERMISSIONS.add ("user_birthda...

Opencart and VQMOD issue: Could not load controller in vq2-system_engine_controller.php -

I am using Opencart 1.5.6.1 and VQMOD 2.4.1. I have installed the Ewe Rapid 3.0 extension now and at checkout, I get this error: Notice: Error: Controller payment / EVE could not be loaded! On line 47 trigger_error ('Error: Could not load controller'. ($) At $ ($) ... \ vqmod \ vqcache \ vq2-system_engine_controller.php in line children!

Steps to try: Check if you have a eway.php in the list / controller / payment folder Verify the square name of that file: Class Controller Payment and Controller { . Check file permissions. It's a good day!

deployment - How to upload Parent child SSIS package to server -

Image
Hi all I am very new to SSIS I got some SSIS package developed by some other person, this flat after package mapping. Reads data from files and stores in the database. Flow: 1) To first extract the package into the flat file and in the table in the store 2) Then it calls the child package using the package package. 3) Then baby packages do some calculations and update the database table. The SSIS database is using environment variables to get information. Everything is working fine, but now I want to deploy it to the package on my client's server. Q: Do I need to copy and paste from the bin folder and paste it on the client machine? What I tried: I copy the file from the bin folder and keep it on my local computer. Then I prepare a job in MSSQL and run the work. The package runs completely but later I changed the location of my project and the problem started, the work stopped. Problem: An error says that the location of the hair package is not available (as I have changed ...
