一个简单的JBPM4.4实现的一个请假流程：

package com.leweiyou.main;

import static org.junit.Assert.assertNotNull;import static org.junit.Assert.assertTrue;import java.util.HashMap;import java.util.List;import java.util.Map;import java.util.Set;import org.jbpm.api.Configuration;import org.jbpm.api.Deployment;import org.jbpm.api.ExecutionService;import org.jbpm.api.ProcessEngine;import org.jbpm.api.ProcessInstance;import org.jbpm.api.RepositoryService;import org.junit.Before;import org.junit.Test;public class HellowordTest {private ProcessEngine engine;@Beforepublic void setUp() throws Exception {engine = Configuration.getProcessEngine();}/** * 发布流程 */@Testpublic void testDeploy(){RepositoryService rs = engine.getRepositoryService();String id = rs.createDeployment().addResourceFromClasspath("jpdl/helloword.jpdl.xml").deploy();assertNotNull(id);}@Testpublic void testPrintDeploy(){RepositoryService repositoryService = engine.getRepositoryService();List<Deployment> list = repositoryService.createDeploymentQuery().list();assertTrue(list.size() != 0);for(Deployment d : list){assertNotNull(d);System.out.println("Deployment:" + d.getId() + " " + d.getName());}}/** * 测试 1天，经理，同意，结束 */@Testpublic void testWrite_1_leader(){//开始ExecutionService es = engine.getExecutionService();ProcessInstance pi = es.startProcessInstanceByKey("Helloword");Set<String> ans = pi.findActiveActivityNames();String pid = pi.getId();assertTrue(ans != null && ans.contains("填写申请"));//填写请假单Map<String,Object> map = new HashMap<String,Object>();map.put("day", 1);map.put("reason", "请假");pi = es.signalExecutionById(pid, map);ans = pi.findActiveActivityNames();assertTrue(ans != null && ans.contains("经理审批"));//经理审批pi = es.signalExecutionById(pid,"同意");assertTrue(pi.isEnded());}/** * 测试 1天，经理，不同意 */@Testpublic void testWrite_1_$(){//开始ExecutionService es = engine.getExecutionService();ProcessInstance pi = es.startProcessInstanceByKey("Helloword");Set<String> ans = pi.findActiveActivityNames();String pid = pi.getId();assertTrue(ans != null && ans.contains("填写申请"));//填写请假单Map<String,Object> map = new HashMap<String,Object>();map.put("day", 1);map.put("reason", "请假");pi = es.signalExecutionById(pid, map);ans = pi.findActiveActivityNames();assertTrue(ans != null && ans.contains("经理审批"));//经理审批Map<String,Object> map1 = new HashMap<String,Object>();map1.put("reason", "经理不同意：请假次数太多，已经超过了月量");pi = es.signalExecutionById(pid,"驳回",map1);ans = pi.findActiveActivityNames();assertTrue(ans != null && ans.contains("填写申请"));assertTrue(!pi.isEnded());}/** * 测试 10天，经理，同意，老板不同意 */@Testpublic void testWrite_10_$(){//开始ExecutionService es = engine.getExecutionService();ProcessInstance pi = es.startProcessInstanceByKey("Helloword");Set<String> ans = pi.findActiveActivityNames();String pid = pi.getId();assertTrue(ans != null && ans.contains("填写申请"));//填写请假单Map<String,Object> map = new HashMap<String,Object>();map.put("day", 10);map.put("reason", "请假");pi = es.signalExecutionById(pid, map);ans = pi.findActiveActivityNames();assertTrue(ans != null && ans.contains("经理审批"));//经理审批pi = es.signalExecutionById(pid,"同意");ans = pi.findActiveActivityNames();assertTrue(ans != null && ans.contains("老板审批"));//老板审批Map<String,Object> map1 = new HashMap<String,Object>();map1.put("reason", "老板不同意：项目太紧，过两天请假吧");pi = es.signalExecutionById(pid,"驳回",map1);ans = pi.findActiveActivityNames();assertTrue(ans != null && ans.contains("填写申请"));assertTrue(!pi.isEnded());}/** * 测试 10天，经理，同意，老板同意，结束 */@Testpublic void testWrite_10_leader(){//开始ExecutionService es = engine.getExecutionService();ProcessInstance pi = es.startProcessInstanceByKey("Helloword");Set<String> ans = pi.findActiveActivityNames();String pid = pi.getId();assertTrue(ans != null && ans.contains("填写申请"));//填写请假单Map<String,Object> map = new HashMap<String,Object>();map.put("day", 10);map.put("reason", "请假");pi = es.signalExecutionById(pid, map);ans = pi.findActiveActivityNames();assertTrue(ans != null && ans.contains("经理审批"));//经理审批pi = es.signalExecutionById(pid,"同意");ans = pi.findActiveActivityNames();assertTrue(ans != null && ans.contains("老板审批"));//老板审批pi = es.signalExecutionById(pid,"同意");assertTrue(pi.isEnded());}}
