पर context.xml फ़ाइल को जोड़ने के लिए कैसे मैं स्प्रिंग-बूट का उपयोग कर एम्बेडेड टॉमकैट सर्वर में अपना एप्लिकेशन चलाने की कोशिश कर रहा हूं। मेरे पास मेरे जेएनडीआई संसाधन और वातावरण एक एक्सएमएल फ़ाइल में कॉन्फ़िगर किए गए हैं, जो मेरे आवेदन में src/main/webapp/META-INF/context.xml के अंतर्गत रखा गया है। जब मैं इस एप्लिकेशन को एक मानक सर्वलेट कंटेनर में तैनात करता हूं तो यह काम करता है। लेकिन जब मैं इसे एक एम्बेडेड सर्वर का उपयोग शुरू करता हूं तो यह संदर्भ फ़ाइलों में मौजूद जेएनडीआई संसाधनों को नहीं पहचानता है।एम्बेडेड टॉमकैट सर्वर
मैंने निम्नलिखित कोड का उपयोग करके प्रोग्राम फ़ाइल को एम्बेडेड टॉमकैटकंटनर में जोड़ने की कोशिश की। इस blog से कहा जाता है -
@Bean
public TomcatEmbeddedServletContainerFactory tomcatFactory() {
return new TomcatEmbeddedServletContainerFactory() {
@Override
protected TomcatEmbeddedServletContainer getTomcatEmbeddedServletContainer(
Tomcat tomcat) {
tomcat.enableNaming();
Context context = new StandardContext();
File f = new File("D:\\Workspace\\SpringBoot\\src\\main\\webapp\\META-INF\\context.xml");
try {
context.setConfigFile(f.toURI().toURL());
tomcat.getHost().addChild(context);
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return super.getTomcatEmbeddedServletContainer(tomcat);
}
लेकिन मैं निम्नलिखित अपवाद हो रही है। क्या कोई मुझे बता सकता है कि एम्बेडेड टॉमकैट सर्वर पर context.xml फ़ाइलों को कैसे जोड़ना है?

मैं भी कुछ अधिक बिल्ला एपीआई की कोशिश की context.xml फ़ाइल एम्बेडेड सर्वर उदाहरण के लिए (जो कई JNDI संसाधन और वातावरण में परिभाषित किया गया है) लोड करने के लिए है, लेकिन मैं एक मिलती रहती है शून्य सूचक अपवाद। पीएफबी विभिन्न एपीआई जिन्हें मैंने उपयोग करने की कोशिश की।
1. tomcat.addContext("/my-boot", System.getProperty("user.dir")+ "/src/main/webapp/META-INF/context.xml");
2. StandardContext context = new StandardContext();
context.setDefaultContextXml(System.getProperty("user.dir") + "/src/main/webapp/META-INF/context.xml");
tomcat.getHost().addChild(context);
जबकि बिल्ला मेरी संसाधन के नाम पर प्राप्त करने के लिए कोशिश कर रहा है दोनों दृष्टिकोण के लिए मैं एक NullPointerException हो रही है। एपीआई विधियों के नाम से, मुझे लगता है कि ऐसा करने का एक तरीका होना चाहिए। कृपया इसके साथ सहायता करें।

@ImportResource एनोटेशनेशन.xml फ़ाइल को स्प्रिंग रिसोर्स के रूप में आयात करने का प्रयास कर रहा है, लेकिन मुझे नहीं लगता कि टॉमकैट की context.xml फ़ाइल की स्कीमा स्प्रिंग द्वारा समझा जाएगा। तो मुझे एक्सएमएल पार्स अपवाद मिल रहा है। यह संदर्भ एक्सएमएल सीधे टोमकैट उदाहरण में लोड किया जाना चाहिए। – SanjaySSN
पोस्टप्रोकस कॉन्टेक्स्ट (संदर्भ संदर्भ) विधि को ओवरराइड करके टॉमकैट के जेएनडीआई में संसाधन जोड़ना, लेकिन हमारे पास हमारे संदर्भ.एक्सएमएल फ़ाइल में 50 से अधिक संदर्भ संसाधन और वातावरण परिभाषित हैं। तो उस दृष्टिकोण को लेने से पहले, मैं जानना चाहता हूं कि एम्बेडेड टॉमकैट इंस्टेस में context.xml फ़ाइल को लोड करना संभव है या नहीं। – SanjaySSN
संपादन जोड़ा गया, कृपया आगे पूछे जाने पर वापस लौटें। धन्यवाद। –
