Getting CommandBean or form bean object with out @ModelAttribute in spring mvc -

-

मुझे कूटबन्धन या बीन ऑब्जेक्ट को नियंत्रक में @ModelAttribute का उपयोग किए बिना प्राप्त करने की आवश्यकता है

JSP: 

  & lt; फ़ॉर्म: form commandName = "user" method =  
 "पोस्ट" एक्शन = "$ {pageContext.request.contextPath} / उपयोगकर्ता / निर्मित उपयोगकर्ता" & gt; नाम: & lt; फ़ॉर्म: इनपुट पथ = "नाम" / & gt; पासवर्ड: & lt; फ़ॉर्म: इनपुट पथ = "पासवर्ड" / & gt; & Lt; इनपुट प्रकार = "सबमिट करें" / & gt; & Lt; / प्रपत्र: प्रपत्र & gt; नियंत्रक:  
  @Controller @RequestMapping ("/ उपयोगकर्ता") सार्वजनिक वर्ग UserController {@RequestMapping (method = RequestMethod.GET) सार्वजनिक स्ट्रिंग सेटअपफ़ॉर्म ( मॉडलमैप मॉडल) {modelMap.addAttribute ("उपयोगकर्ता", नया उपयोगकर्ता ()); वापसी "userRegistration"; } @RequestMapping (मान = "/ createUser", method = RequestMethod.POST) सार्वजनिक स्ट्रिंग createUser (ModelMap मॉडल, HttpServletRequest अनुरोध) {उपयोगकर्ता उपयोगकर्ता = (उपयोगकर्ता) model.get ("उपयोगकर्ता"); // Retruns wanna // test अनुरोध ऑब्जेक्ट का उपयोग करते हुए लेकिन उपयोगकर्ता ऑब्जेक्ट इसमें उपलब्ध नहीं है वापसी "संदेश"; }}   
 मैंने अलग-अलग तरीकों से कोशिश की लेकिन कुछ भी काम नहीं किया।   
 
 
 मैन्युअल रूप से बीन बनाने के लिए आप एक को लागू कर सकते हैं, फिर (उदाहरण के लिए) इसे घोषित करने के लिए इसका उपयोग करें। तर्क समाधानकर्ताओं का समर्थन करता है पैरामीटर विधि को पैरामीटर के अपेक्षित प्रकार की जांच करनी चाहिए। इसके बाद आप अपने नियंत्रक में एक पैरामीटर जोड़ सकते हैं जो इच्छित प्रकार का है।

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...
