Question

The solution to this is probably very simple, but I’m not sure what I’m missing. Here’s what I have, and PropertyPlaceholderConfigurer won’t replace the ${...}.

/* ---- org/company/springtest/Test.java: ---- */ package org.company.springtest;  import org.springframework.beans.factory.xml.XmlBeanFactory; import org.springframework.core.io.FileSystemResource; import org.springframework.core.io.Resource;  public class Test {     public static void main( String... args ) {          Resource res = new FileSystemResource('conf/xml/context2.xml');              XmlBeanFactory beanFactory = new XmlBeanFactory(res);              TestApp app = (TestApp) beanFactory.getBean('testApp');              app.print();     }    }   /* ---- org/company/springtest/TestApp.java: ---- */ package org.company.springtest; import org.springframework.beans.factory.annotation.Required;  public class TestApp {     private String m_message;      public void setMessage( String message ) {          m_message = message;     }      public void print() {         System.out.println(m_message);     } }  /* ---- conf/xml/context2.xml: ---- */ <?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:lang='http://www.springframework.org/schema/lang' xsi:schemaLocation=' http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd'>      <bean class='org.springframework.beans.factory.config.PropertyPlaceholderConfigurer'>         <property name='locations' value='file:conf/xml/test.properties' />     </bean>     <bean id='testApp' class='org.company.springtest.TestApp'>          <property name='message' value='${test.message}'/>     </bean> </beans>  /* ---- conf/xml/test.properties: ---- */ test.message=Hello world! 

The following is the output when running Test:

Feb 17, 2009 11:23:06 AM org.springframework.beans.factory.xml.XmlBeanDefinitionReader loadBeanDefinitions INFO: Loading XML bean definitions from file [C:\eclipse\workspace\SpringTest\conf\xml\context2.xml] ${test.message} 

It looks like the Configurer is not replacing the property values…

Perhaps try using an ApplicationContext instead of a BeanFactory?
