Ich versuche, Eigenschaften aus einer .propertiesDatei zu verwenden, aber es scheint nicht zu funktionieren.
Hier ist mein Code:
@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;
[...]
}
Diese Klasse verwendet @ValueAnmerkungen, um die Eigenschaften abzurufen. Es ist auch als Spring Service deklariert und mit meiner infraContext.xmlDatei verknüpft :
<?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>
Mit context:property-placeholderverknüpfe ich diese Datei mit meiner context-core.propertiesDatei:
project.ftp.adresse = localhost
project.ftp.login = anonymous
project.ftp.password =
project.ftp.root = /anonymous/
Das macht doch Sinn, oder?
Wenn ich jedoch versuche, mein Projekt zu starten, löst Tomcat diese Ausnahme aus:
ERROR [context.ContextLoader.initWebApplicationContext()] Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'ServiceFTP': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private java.lang.String project.sins.service.impl.ServiceFTPImpl.adresse; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'project.ftp.adresse' in string value "${project.ftp.adresse}"

Mir fehlt offensichtlich etwas, aber ich kann nicht herausfinden, was.
Bitte lassen Sie mich wissen, wenn Sie weitere Details benötigen, da dies meine erste Frage hier ist, werde ich versuchen, sie so schnell wie möglich zu beantworten :).
infraContext.xmlgeladen? Dem Stacktrace nach zu urteilen, ist es nicht in der Konfiguration enthalten, die von der geladen wirdContextLoaderListener. Bitte posten Sie Ihre web.xml.
