मैं एक .properties
फ़ाइल से गुणों का उपयोग करने की कोशिश कर रहा हूं , लेकिन यह काम नहीं करता है।
यहाँ मेरा कोड है:
@Service("ServiceFTP")
@Transactional
public class ServiceFTPImpl implements ServiceFTP {
@Value("${project.ftp.adresse}")
private String adresse;
@Value("${project.ftp.login}")
private String compte;
@Value("${project.ftp.password}")
private String motDePasse;
@Value("${project.ftp.root}")
private String ROOT;
[...]
}
यह वर्ग @Value
गुण प्राप्त करने के लिए एनोटेशन का उपयोग करता है । इसे स्प्रिंग सेवा के रूप में भी घोषित किया गया है और यह मेरी infraContext.xml
फाइल से जुड़ी है :
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd">
<context:property-placeholder location="classpath:context-core.properties"/>
[...]
</beans>
का उपयोग करते हुए context:property-placeholder
, मैं इस फ़ाइल को अपनी context-core.properties
फ़ाइल से लिंक करता हूं :
project.ftp.adresse = localhost
project.ftp.login = anonymous
project.ftp.password =
project.ftp.root = /anonymous/
यह समझ में आता है, है ना?
लेकिन जब मैं अपना प्रोजेक्ट लॉन्च करने की कोशिश करता हूं, तो टॉमकैट इस अपवाद को फेंक देता है:

मैं स्पष्ट रूप से कुछ याद कर रहा हूं, लेकिन मैं यह पता नहीं लगा सकता कि क्या।
कृपया मुझे बताएं कि क्या आपको अधिक जानकारी की आवश्यकता है, क्योंकि यह मेरा पहला सवाल है, मैं जल्द से जल्द जवाब देने की कोशिश करूंगा :)।
infraContext.xml
लोड कहाँ हो रहा है? स्टैकट्रेस से देखते हुए यह द्वारा लोड किए गए कॉन्फ़िगरेशन में शामिल नहीं हैContextLoaderListener
। कृपया अपना web.xml पोस्ट करें।
