第一步：  

Help -->Install New Software...

ClickAdd...

In dialogAdd Site dialog, clickArchive...

Navigate toinstall/src/gpd/jbpm-gpd-site.zip and click 'Open'

ClickingOK in theAdd Site dialog will bring you back to the dialog 'Install'

Select thejPDL 4 GPD Update Site that has appeared

ClickNext... and thenFinish

Approve the license

Restart eclipse when that is asked

第二步：

流程定义文件的xsd文件的路径为：JBPM_HOME/src/jpdl-4.4.xsd。

添加到Eclipse中的方法为（jBPM4.4User Guide, 2.11.5. Adding jPDL 4 schema tothe catalog）：

  ClickWindow -->Preferences

  SelectXML -->XML Catalog

  Click 'Add...'

  The 'Add XML Catalog Entry' dialog opens

  Click the button with the map-icon next to location and select 'FileSystem...'

  In the dialog that opens, select filejpdl-4.4.xsd in the src directoryof the jBPM installation root.

  Click 'Open' and close all the dialogs

第三步：添加jar包

1. JBPM解压目录下有一个重要的jar包：jbpm.jar。

2. JBPM/lib目录下的jar很多，不要添加的jar包：servlet-api.jar、junit.jar（尤其不要添加）。

3. 所使用的数据库对应的驱动的jar包在上面lib目录当中已经有了，所以不需要添加了。

<?xml version="1.0" encoding="UTF-8"?><jbpm-configuration><import resource="jbpm.default.cfg.xml" /><import resource="jbpm.businesscalendar.cfg.xml" /><import resource="jbpm.tx.hibernate.cfg.xml" /><import resource="jbpm.jpdl.cfg.xml" /><import resource="jbpm.bpmn.cfg.xml" /><import resource="jbpm.identity.cfg.xml" /><!-- Job executor is excluded for running the example test cases. --><!-- To enable timers and messages in production use, this should be included. --><!--<import resource="jbpm.jobexecutor.cfg.xml" />--></jbpm-configuration>

jbpm.cfg.xml

<?xml version="1.0" encoding="utf-8"?><!DOCTYPE hibernate-configuration PUBLIC"-//Hibernate/Hibernate Configuration DTD 3.0//EN""http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"><hibernate-configuration><session-factory><!-- 数据库信息 --><property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property><property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property><property name="hibernate.connection.url">jdbc:mysql:///jbpm4test</property><property name="hibernate.connection.username">root</property><property name="hibernate.connection.password">root</property><!-- 其他配置 --><property name="hibernate.hbm2ddl.auto">update</property><!-- 导入映射文件 --><mapping resource="jbpm.repository.hbm.xml" /><mapping resource="jbpm.execution.hbm.xml" /><mapping resource="jbpm.history.hbm.xml" /><mapping resource="jbpm.task.hbm.xml" /><mapping resource="jbpm.identity.hbm.xml" /></session-factory>
</hibernate-configuration>

jbpm.hibernate.cfg.xml

4.3 JBPM工作流的使用

1. 创建jbpm的文件

<?xml version="1.0" encoding="UTF-8"?><process name="员工请假流程" xmlns="http://jbpm.org/4.4/jpdl"><start g="77,20,48,48" name="start1"><transition g="-71,-17" name="to 提交申请" to="提交申请"/></start><end g="77,352,48,48" name="end1"/><task assignee="ww" g="55,268,92,52" name="总经理审批"><transition g="-47,-17" name="to end1" to="end1"/></task><task assignee="ls" g="55,184,92,52" name="部门经理审批"><transition g="-26,-8" name="同意" to="总经理审批"/></task><task assignee="#{applyInfo.applier.userName}" g="55,100,92,52" name="提交申请"><transition g="-96,-16" name="to 部门经理审批" to="部门经理审批"/></task>
</process>

保存之后相应的生成png格式的对应的图片。

4.4 JBPM工作流编程实例

        // 建表@Testpublic void createSchema() {new org.hibernate.cfg.Configuration()//.configure("jbpm.hibernate.cfg.xml")//.buildSessionFactory();}

4.4.2 创建ProcessEngine对象

private static ProcessEngine processEngine = new Configuration()//.setResource("jbpm.cfg.xml")//.buildProcessEngine();

private ProcessEngine processEngine = Configuration.getProcessEngine();

4.4.3 部署流程定义

<span style="white-space:pre">    </span>// 部署流程定义@Testpublic void deployProcessDefinition(){String reponseStr = processEngine.getRepositoryService()//.createDeployment()//.addResourceFromClasspath("test/test.jpdl.xml")//这里目录需要根据自己的目录确定.addResourceFromClasspath("test/test.png")//.deploy();System.out.println(reponseStr);// 10001}

4.4.4 启动流程实例

        // 启动流程实例// jbpm4_execution@Testpublic void testStartProcessInstance() throws Exception {ProcessInstance <strong style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);"></strong><pre name="code" class="java" style="display: inline !important;">processInstance 

= processEngine.getExecutionService().startProcessInstanceByKey("test");System.out.println("流程实例启动成功：id=" +

processInstance <strong style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);"></strong><pre name="code" class="java" style="display: inline !important;">.getId() //

+ ", state=" +

processInstance

.getState() // 状态+ ", processDefinitionId=" +

processInstance

.getProcessDefinitionId()); // 所使用的流程定义的ID} 2. 通过key获取并直接启动实例

        // 启动实例@Testpublic void startProcessInstance() {processEngine.getExecutionService().startProcessInstanceByKey("test");}

4.4.5 查看个人的任务列表

        // 查询任务列表@Testpublic void findTaskList() {List<Task> taskList = processEngine.getTaskService().findPersonalTasks("员工");System.out.println("个人任务列表");System.out.println(taskList);for(Task task : taskList){System.out.println("id= " + task.getId() + ", name = " + task.getName() + ", assignee = " + task.getAssignee());}}

4.4.8 删除流程定义

        // 删除@Testpublic void deleteById() throws Exception {String deploymentId = "80001";// // 删除指定的部署对象（流程定义），如果有关联的执行信息，就会报错// processEngine.getRepositoryService().deleteDeployment(deploymentId);// 删除指定的部署对象（流程定义），如果有关联的执行信息，会被同时删除processEngine.getRepositoryService().deleteDeploymentCascade(deploymentId);}

        // 删除指定key的所有版本的流程定义@Testpublic void deleteByKey() throws Exception {// 查询出指定key的所有版本的流程定义List<ProcessDefinition> list = processEngine.getRepositoryService()//.createProcessDefinitionQuery()//.processDefinitionKey("helloworld")//.list();// 一一删除for (ProcessDefinition pd : list) {processEngine.getRepositoryService().deleteDeploymentCascade(pd.getDeploymentId());}}

4.4.9 查看流程图
