Jbpm4.4 API实例操作与流程管理详解

jbpm4.4 Api 示例
(一)：工作流服务引擎ProcessEngine
import java.util.List;
import org.jbpm.api.*;
public class testJbpm {
 public void test(){
  //启动工作流服务引擎 初始化ProcessEngine 会自动读取jbpm.cfg.xml
  ProcessEngine  proessEngine = Configuration.getProcessEngine();
  //流 程 管理 对象：RepositoryService
  RepositoryService rs = proessEngine.getRepositoryService();
  //rs 作用1：发布qh_jbpm.jpdl.xml工作流
  String id = rs.createDeployment().addResourceFromClasspath("qh_jbpm.jpdl.xml").deploy();
  //rs 作用2：查找流程定义列表
  List <ProcessDefinition> dfList = rs.createProcessDefinitionQuery().list();
  //rs 作用3：删除流程定义
  rs.deleteDeploymentCascade(id);
  //流程实例管理ExecutionService类
  ExecutionService es = proessEngine.getExecutionService();
  //获得流和程实例
  ProcessInstance pi = es.startProcessInstanceByKey("qh_jbpm");
  //将流程 实例执行下一步
  es.signalExecutionById(pi.getId());
  //将流程实例不再执行强行终止
  es.endProcessInstance(pi.getId(), "终止理由");
  //将流程 实例删除
  es.deleteProcessInstanceCascade(pi.getId());
  //查看流程 下的实例集合
  List <ProcessInstance> piList = es.createProcessInstanceQuery().list();
 }
