Question

下面是调用changeset.xml的主java文件。在没有changeset.xml的情况下使用时，changeset.xml中提供的规则文件在执行时不会执行。

        ResourceFactory.getResourceChangeNotifierService().start(); 
        ResourceFactory.getResourceChangeScannerService().start(); 

        ResourceChangeScannerConfiguration sconf = ResourceFactory.getResourceChangeScannerService().newResourceChangeScannerConfiguration(); 
        sconf.setProperty("drools.resource.scanner.interval", "10"); 
        ResourceFactory.getResourceChangeScannerService().configure(sconf); 

        KnowledgeAgentConfiguration aconf = KnowledgeAgentFactory.newKnowledgeAgentConfiguration(); 
        aconf.setProperty("drools.agent.scanDirectories", "true"); 
        aconf.setProperty("drools.agent.scanResources", "true"); 
        aconf.setProperty("drools.agent.newInstance", "false");



         //  KnowledgeBuilder kbuilder1 = KnowledgeBuilderFactory.newKnowledgeBuilder();
        //  kbuilder1.add( ResourceFactory.newFileResource("file:C://Users//latika.vashishtha.in//Workspace 2//AppChangeset1//src//test//resources//change-set.xml"),ResourceType.CHANGE_SET );

        KnowledgeAgent knowledgeAgent = KnowledgeAgentFactory.newKnowledgeAgent("AGENT", aconf); 

            knowledgeAgent.applyChangeSet(ResourceFactory.newFileResource("file:C://Users//latika.vashishtha.in//Workspace 2//AppChangeset1//src//test//resources//Sample.drl" )); 
             knowledgeAgent.addEventListener(new DebugKnowledgeAgentEventListener());
             return knowledgeAgent.getKnowledgeBase();

您正在传递drl而不是更改集

    KnowledgeAgentConfiguration aconf = KnowledgeAgentFactory.newKnowledgeAgentConfiguration(); 
    aconf.setProperty("drools.agent.scanDirectories", "true"); 
    aconf.setProperty("drools.agent.scanResources", "true"); 
    aconf.setProperty("drools.agent.newInstance", "false");

    KnowledgeBuilder kbuilder1 = KnowledgeBuilderFactory.newKnowledgeBuilder();
    kbuilder1.add( ResourceFactory.newFileResource("file:C://Users//latika.vashishtha.in//Workspace 2//AppChangeset1//src//test//resources//Sample.drl"),ResourceType.DRL );
    assertFalse( kbuilder.hasErrors());
    KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();

    KnowledgeAgent knowledgeAgent = KnowledgeAgentFactory.newKnowledgeAgent("AGENT", kbase, aconf); 

    knowledgeAgent.applyChangeSet(ResourceFactory.newFileResource("file:C://Users//latika.vashishtha.in//Workspace 2//AppChangeset1//src//test//resources//change-set.xml" )); 
    knowledgeAgent.addEventListener(new DebugKnowledgeAgentEventListener());

    ResourceChangeScannerConfiguration sconf = ResourceFactory.getResourceChangeScannerService().newResourceChangeScannerConfiguration(); 
    sconf.setProperty("drools.resource.scanner.interval", "10"); 
    ResourceFactory.getResourceChangeScannerService().configure(sconf);
    ResourceFactory.getResourceChangeNotifierService().start(); 
    ResourceFactory.getResourceChangeScannerService().start(); 
    return knowledgeAgent.getKnowledgeBase();

Drools：规则文件未使用change-set.xml执行
