Question

我是Drools的新手，我在eclipse IDE中使用drools 5.5.0最终运行时Maven项目。

当我在Maven中运行项目时，会抛出以下错误 cvc-elt.1：找不到元素的声明＆＃39; change-set＆＃39;。

这是控制流程

SampleDroolRule.java

public class SampleDroolRule extends RuleTestBase {
  private static List<Object> mockPropertySet;
  public SampleDO runRules(List<Object> mockPropertySet) {
     StatelessKnowledgeSession ks = createRuleEngine("SampleTest.xml", logger);

＆＃39; createRuleEngine＆＃39;打电话到

protected static StatelessKnowledgeSession createRuleEngine(String changeSetXML, Logger logger) {

    logger.info("Creating KS from " + changeSetXML);
    KnowledgeBuilder builder = KnowledgeBuilderFactory.newKnowledgeBuilder();

    builder.add(ResourceFactory.newClassPathResource(changeSetXML), ResourceType.CHANGE_SET);

builder.add行抛出错误

  [main] ERROR org.drools.xml.ExtensibleXmlParser  - (null: 4, 188): cvc-elt.1: Cannot find the declaration of element 'change-set'.

SampleTest.xml看起来像这样

<?xml version="1.0" encoding="UTF-8"?>
<change-set xmlns='http://drools.org/drools-5.0/change-set'
 xmlns:xs='http://www.w3.org/2001/XMLSchema-instance'
 xs:schemaLocation='http://drools.org/drools-5.0/change-set.xsd http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-   api/src/main/resources/change-set-1.0.0.xsd' >
<add>
<resource source='classpath:rules/sample/drls/SampleRules.drl' type='DRL' />
</add>
</change-set>

我现在花了2天多的时间。经历了大量的论坛，没有运气。请帮帮我。谢谢！

Answer 1

从xs：schemaLocation的URL中删除空格（drools- api）可能会有所帮助。

但是，我建议您修改<change-set>中的SampleTest.xml元素属性，以便xs:schemaLocation引用change-set.xsd或change-set-1.0.0.xsd的本地副本。

<change-set xmlns='http://drools.orchange-set-1.0.0.xsdg/drools-5.0/change-set'
 xmlns:xs='http://www.w3.org/2001/XMLSchema-instance'
 xs:schemaLocation='file:///...'>

您可以在分发档案的sources目录中找到XML Schema文件。

Answer 2

我也面临同样的错误。最后，通过更改xml和主类代码内容来解决此问题，如下所示

并在您的主要课程中添加以下代码段

<change-set xmlns='http://drools.org/drools-5.0/change-set'
             xmlns:xs='http://www.w3.org/2001/XMLSchema-instance'
             xs:schemaLocation='http://drools.org/drools-5.0/change-set http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-api/src/main/resources/change-set-1.0.0.xsd' >
  <add>
  <resource source='file:file-path/file-name.drl' type='DRL' />
  <resource source='file:file-path/file-name.bpmn' type='BPMN2' />
   </add>
 </change-set>

kbuilder.add（ResourceFactory.newInputStreamResource（new FileInputStream（“yourfileName.xml”））， ResourceType.CHANGE_SET）;

然后将yourfileName.xml放在项目根目录

中

希望它有所帮助。
