  • Propertyplaceholder not workign with request scope

    Hi everyone,
    I need to resolve a strange issue with spring propertyplaceholder. I have a subclass of PropertyPlaceholderConfigurer in which i am setting the location of the properties file to load based on some request parameter. So i want this bean to be created dynamically based on each request. Below is the code:
    Code:
    public class IntegrationPropertyPlaceholderConfigurer extends PropertyPlaceholderConfigurer{
    	
    	
    	public IntegrationPropertyPlaceholderConfigurer() {
    		ResourceLoader resourceLoader = new DefaultResourceLoader();
    		Resource resource;
    		HttpServletRequest request=((ServletRequestAttributes)RequestContextHolder.currentRequestAttributes()).getRequest();
    		if(request.getParameter("areavpath")!= null && request.getParameter("areavpath").contains("SFDC")){
    			resource= resourceLoader.getResource("classpath:com/vmware/cms/integration/properties/SFDC.properties");
    			super.setLocation(resource);
    		//	this.postProcessBeanFactory(context.getBeanFactory());
    		}else if(request.getParameter("areavpath")!= null && request.getParameter("areavpath").contains("MYVMWARE")){
    			resource= resourceLoader.getResource("classpath:com/vmware/cms/integration/properties/MyVMWare.properties");
    			super.setLocation(resource);
    		//	this.postProcessBeanFactory(context.getBeanFactory());
    		}
    	}
    	
    }
    And my spring configuration is
    Code:
    <bean id="PropertyConfigurer"
    			class="com.vmware.cms.integration.utility.IntegrationPropertyPlaceholderConfigurer"
    			lazy-init="true" scope="request">
    			<aop:scoped-proxy />
    </bean>
    I have added a requestcontext listener in my web.xml for using request scoped beans. But when i start my server i still get the error:
    Code:
    No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.
    Also the bean is not getting created for each request. It is working like a singleton bean. Please help me out!!! Could not find resolution anywhere !!!

          What you are doing is dangerous and is something you shouldn't do. You are reconfiguring all your beans on each request (including your singletons) now imagine concurrent requests each changing the configuration...

          Also your placeholder shouldn't be an aop:scoped-proxy as you aren't using it for dependency injection.
