[jboss-jira] [JBoss JIRA] Updated: (JBCACHE-89) Allow Specifying Custom Interceptors in XML Configuration

Allow Specifying Custom Interceptors in XML Configuration --------------------------------------------------------- Key: JBCACHE-89 URL: http://jira.jboss.com/jira/browse/JBCACHE-89 Project: JBoss Cache Issue Type: Feature Request Affects Versions: 1.2 Reporter: Daniel Gredler Assigned To: Manik Surtani Fix For: 3.0.0 Original Estimate: 1 day Time Spent: 30 minutes Remaining Estimate: 7 hours, 30 minutes It would be nice to be able to add interceptors via the XML configuration files. Indeed, in TreeCache.java the following comment exists, which may indicate that this feature is already planned: // Create the interceptors in the correct order (later to be defined in XML file) createInterceptorChain(); A possible example configuration would be: <server> <classpath codebase="./lib" archives="jboss-cache.jar, jgroups.jar" /> <mbean code="org.jboss.cache.TreeCache" name="jboss.cache:service=TreeCache"> ... <attribute name="Interceptors"> <interceptor>com.foo.project.MyInterceptor</interceptor> </attribute> ... </mbean> </server> Something along the lines of the following method would then be able to add the custom interceptors (in TreeCache.java): public void setInterceptors(Element interceptors) throws Exception { NodeList list = interceptors.getChildNodes(); for(int i = 0; i < list.getLength(); i++) { org.w3c.dom.Node node = list.item(i); if(node.getNodeType() != org.w3c.dom.Node.ELEMENT_NODE) continue; NodeList children = node.getChildNodes(); if(children.getLength() != 1) continue; org.w3c.dom.Node childNode = list.item(0); if(childNode.getNodeType() != org.w3c.dom.Node.TEXT_NODE) continue; String className = childNode.getNodeValue(); if(className == null || className.length() == 0) continue; Interceptor interceptor = createInterceptor(className); addInterceptor(interceptor_chain, interceptor); } }
