drools - 找不到 org.drools.builder.KnowledgeType drrols 类

Question

在尝试执行第 2.3 节中的 Helloword 流程示例时

• https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/docs/drools-flow/html_single/index.html#d4e24站点找不到下面提到的类。

org.drools.builder.KnowledgeType

谁能告诉我可以从哪个包中获得这门课？

谢谢！

文档的那部分似乎有点过时了。您应该使用资源类型。我已经使用以下代码片段更新了文档（一旦构建成功，您也应该出现在您正在使用的链接上）：

package com.sample;

import org.drools.KnowledgeBase;
import org.drools.builder.KnowledgeBuilder;
import org.drools.builder.KnowledgeBuilderFactory;
import org.drools.builder.ResourceType;
import org.drools.io.ResourceFactory;
import org.drools.logger.KnowledgeRuntimeLogger;
import org.drools.logger.KnowledgeRuntimeLoggerFactory;
import org.drools.runtime.StatefulKnowledgeSession;

/**
 * This is a sample file to launch a process.
 */
public class ProcessTest {

  public static final void main(String[] args) {
    try {
      // load up the knowledge base
      KnowledgeBase kbase = readKnowledgeBase();
      StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
      KnowledgeRuntimeLogger logger = KnowledgeRuntimeLoggerFactory.newFileLogger(ksession, "test");
      // start a new process instance
      ksession.startProcess("com.sample.ruleflow");
      logger.close();
    } catch (Throwable t) {
      t.printStackTrace();
    }
  }

  private static KnowledgeBase readKnowledgeBase() throws Exception {
    KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
    kbuilder.add(ResourceFactory.newClassPathResource("ruleflow.rf"), ResourceType.DRF);
    return kbuilder.newKnowledgeBase();
  }
}
