copied!<p>If you're going to use <code>@Bean</code>, you'll need <code>@Configuration</code>. You shouldn't declare a xml context to include an annotation context. You also shouldn't use your <code>@Configuration</code> class instance as a bean. <code>ClassPathXmlApplicationContext</code> is no good for processing annotation based configurations.</p> <p>Use something like the following</p> <pre><code>@Configuration @ComponentScan(basePackageClasses = LoadProperties.class) public static class Config { @Bean public static PropertyPlaceholderConfigurer props() { PropertyPlaceholderConfigurer ppc = new PropertyPlaceholderConfigurer(); Resource[] resource = new ClassPathResource[] { new ClassPathResource( "/EclipseProjectName/src/cluster.properties") }; ppc.setLocations(resource); ppc.setIgnoreUnresolvablePlaceholders(true); return ppc; } @Bean public LoadProperties loadProperties() { return new LoadProperties(); } } public static class LoadProperties { private @Value("${cluster.zooServers}") String zooServers; ... // getters and setters } public static void main(String[] args) throws Exception { AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(Config.class); LoadProperties load = (LoadProperties) context.getBean(LoadProperties.class); System.out.println(load.getZooServers()); } </code></pre> <p>A few things to note: </p> <ol> <li>In your <code>ClassPathResource</code> you need to specify a classpath resource. Do you really have a resource <code>/EclipseProjectName/src/cluster.properties</code> at the root of your classpath? I very much doubt it.</li> <li>In this case you won't need a <code>@ComponentScan</code>, but familiarize yourself with it.</li> <li>A <code>PropertyPlaceholderConfigurer</code> needs to be declared static so it can be initialized before the other <code>@Bean</code> declarations. You should use <code>PropertySourcesPlaceholderConfigurer</code> as <a href="http://docs.spring.io/spring/docs/3.2.x/javadoc-api/org/springframework/beans/factory/config/PropertyPlaceholderConfigurer.html" rel="nofollow">explained in the javadoc</a>.</li> </ol>
