spring - Defining a key in a property map using @Bean -

-

XML विन्यास के निम्नलिखित भाग को देखते हुए: 

  & lt; bean id = "jndiTemplate" वर्ग = "org.springframework.jndi.JndiTemplate" & gt; & Lt; संपत्ति नाम = "पर्यावरण" & gt; & LT; नक्शा & gt; & LT; प्रविष्टि & gt; & Lt; key & gt; & lt; util: निरंतर id = "respectTTL" स्थिर-क्षेत्र = "कॉम .... SOLACE_JMS_RESPECT_TIME_TO_LIVE" / & gt; & Lt; / कुंजी & gt; & Lt; ref bean = "booleanfalse" / & gt; & Lt; / प्रविष्टि & gt; & Lt; / नक्शा & gt; & Lt; / संपत्ति & gt; & Lt; / सेम ​​& gt;

@ बीन : 

  & lt; कुंजी & gt; & lt; util: constant id का उपयोग करके यह भाग जावा में कैसे परिभाषित किया जाएगा = "RespectTTL" स्थिर-फ़ील्ड = "कॉम .... SOLACE_JMS_RESPECT_TIME_TO_LIVE" / & gt; & Lt; / कुंजी & gt;

धन्यवाद

यह वाकई स्पष्ट नहीं है कि आप क्यों हैं इस विषय पर कुछ जावा कोड करने में डर: 

  @ बीन सार्वजनिक जेंडि टेंपलेट जेंडीटाइमप्लेट () {जेडीटीमप्लेट जेन्डीटीमप्लेट = नया जेडीटीमप्लेट (); गुण पर्यावरण = नया गुण (); Environment.setProperty (कॉम .... SOLACE_JMS_RESPECT_TIME_TO_LIVE, "गलत"); jndiTemplate.setEnvironment (पर्यावरण); वापसी jndiTemplate; }

चूंकि आपका निरंतर जावा कोड है और निश्चित रूप से, @ बीन जावा कोड के लिए है, तो आप बस स्प्रिंग जावा कॉन्फ़िग से किसी भी जावा कोड का उपयोग कर सकते हैं।

हमें एक्सएमएल परिभाषा के लिए & lt; util: constant & gt; की आवश्यकता है, क्योंकि हम एक्सएमएल से किसी भी जावा कोड का उपयोग नहीं कर सकते हैं।

बीटीडब्ल्यू कोई कारण नहीं है अनावश्यक सेम के साथ ओवरहेड एप्लिकेशन प्रसंग के लिए, यदि आप अपनी निरंतरता का उपयोग कर सकते हैं।

I am using this code to add value to each series. this.chart1.Series ["green"]. Points. AddY (greenvalue); This.chart1.Series ["totalsaving"] Points.AddY (totalsavingvalue). This.chart1.Series ["blue"] Points.AddY (bluevalue). I have set series properties like this. Both green and totalsaving are set to StackedColumn, the blue chart is set to the column for type.

ruby on rails - Apipie interferes with proper error codes -

I can not find this little bit in the API's docs. Let me make this special AP ready, and I thought I would document it with APP, all fine and dandy, and the ultimate verification is good, but I feel that the response to failure in verification I can not seem to throw the right HTTP code in For example, I have this post / user method, which obviously makes the user in my database good, right? Well, this is something wrong, and it's ok, but if, say, I throw the standards that it does not pass the validity of the apipie, chops apipies and throws a good old-fashioned error, if something is wrong, 422 responds with a fixed unit failure / error: post '/users.json' ,: user = & gt; D Apipie :: ParamInvalid: Invalid parameter 'Email' value "": Regular expression / [a-zA-Z0-9 will match - -] + \ @ [a-zA-Z0-9 \ -.] + \.
