java - Load properties selectively from properties file based on key value -

-

मेरी एक प्रॉपर्टी फाइल है जिसमें 

  xxx.key1 = value1 xxx जैसे मान हैं I Key2 = value2 yyy.key3 = मान 3 yyy.key4 = value4   
  'xxx'  और  'yyy'  को 2 के रूप में माना जा सकता है अलग नाम स्थान मैं संपत्ति फ़ाइल को कैसे लोड कर सकता हूं ताकि मैं केवल  'xxx'  या  'yyy' की       < Class = "post-text" itemprop = "text"> 
 बस फ़ाइल की प्रत्येक पंक्ति को पढ़ें और केवल उस नाम स्थान से मेल खाने वाले मानों को वापस खींचें।  
  स्कैनर स्कैन = नया स्कैनर ( नई फ़ाइल ("yourfilepath")); मानचित्र के & lt; स्ट्रिंग, स्ट्रिंग & gt; नक्शा = नया हैशमैप & lt; स्ट्रिंग, स्ट्रिंग & gt; (); स्ट्रिंग मान = ""; जबकि (scan.hasNext ()) {value = scan.nextLine (); यदि (value.indexOf ("xxx")! = -1) {map.put (value.split ("=") [0], value.split ("=") [1]); }} // अब मैप में आपकी मुख्य वैल्यू युग्म है   
 यदि आपके गुण इस तरह से हैं  
 xxx.key1 = मूल्य तब विभाजन में ("=") ( कोई स्थान नहीं)

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
