jbpm4.4整合spring2.5(ibatis與hibernate全整合)
4
搞了好幾個小時總算運行成功了，記錄一下吧。
首先下載jbpm4.4，解壓出來備用。然后工程自己導入hibernate和spring的jar包以及配置文件。好了可以開始整合了！
整合的先后順序是關鍵，下面按照順序一步一步來設置:
1.首先jbpm是依賴數據庫的，所以可以先創建數據庫，我是mysql數據庫，所以到jbpm-4.4\install\src\db\create中找到jbpm.mysql.create.sql創建文件導入mysql執行！
2.設置spring中hibernate的配置:
可以參考:jbpm-4.4\install\src\cfg\hibernate\spring中的mysql.hibernate.cfg.xml(具體見下面的spring配置文件applicationContext.xml)
3.設置事務，這里由于hibernate和ibatis必須用一個事務，所以使用了TransactionAwareDataSourceProxy來管理事務。(具體見下面的spring配置文件applicationContext.xml)
4.配置默認jbpm的cfg文件，在classpath下創建一個jbpm.cfg.xml,內容如下：
<?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.tx.spring.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>
5.在spring配置文件中注入工作流引擎。(具體見下面的spring配置文件applicationContext.xml)
<!--jbpm4.4工作流 --> <bean id="springHelper" class="org.jbpm.pvm.internal.processengine.SpringHelper"/> <bean id="processEngine" factory-bean="springHelper" factory-method="createProcessEngine" />
6.搞定以上配置文件后添加jbpm.jar, juel-api.jar，juel-engine.jar，juel-impl.jar，mail.jar，這里注意一下，可能有的朋友之后運行還會有錯誤如下：
java.lang.NoSuchMethodError: antlr.collections.AST.getLine()I
這是因為struts2的anltr-2.7.2.jar過舊導致的，我們為了省掉麻煩這里最好直接把struts2的antlr.jar去掉(windows---preferences---在文本框中搜索struts 2(中間有空格)---選擇struts 2---選擇antlr---remove)，然后重新到發布到服務器的lib目錄下刪除anltr-2.7.2.jar即可。
7.成功的關鍵就是applicationContext.xml了，這里把這個關鍵配置貼出來！
<?xml version="1.0" encoding="UTF-8"?>

package com.xuyi.support;
import org.springframework.jdbc.datasource.lookup.AbstractRoutingDataSource;
public class DynamicDataSource extends AbstractRoutingDataSource {
private static ThreadLocal<String> local = new ThreadLocal<String>();
@Override
protected Object determineCurrentLookupKey() {
return local.get() == null ? "dataSource" : local.get();
}
// ---------------------------------------------------------------------------------------------------
/**
* 設置數據源路徑
*/
public static void setRoute(String route) {
if (route==null || route.equals("")){
route = "dataSource";
}
local.set(route);
}
}
8.終于可以開始測試了，先創建一個發布用的xml放入classpath：
測試用的流程swing.jpdl.xml<?xml version="1.0" encoding="UTF-8"?>
<process name="swing" xmlns="http://jbpm.org/4.3/jpdl">
<start g="94,64,48,48" name="start1">
<transition g="-52,-22" name="A" to="A"/>
</start>
<task assignee="A" g="73,195,92,52" name="A">
<transition g="-52,-22" name="B" to="B"/>
</task>
<task assignee="B" g="266,192,92,52" name="B">
<transition g="-40,-21" name="end" to="end1"/>
</task>
<end g="290,327,48,48" name="end1"/>
</process> 然后寫一個測試類進行測試:package com.xuyi.test;
import java.util.List;
import org.jbpm.api.ExecutionService;
import org.jbpm.api.ProcessEngine;
import org.jbpm.api.ProcessInstance;
import org.jbpm.api.TaskService;
import org.jbpm.api.task.Task;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class TestJbpm{
public static void main(String[] args) {
ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
applicationContext.start();
ProcessEngine processEngine = (ProcessEngine)applicationContext.getBean("processEngine");
ExecutionService executionService = processEngine.getExecutionService();
TaskService taskService = processEngine.getTaskService();
//發布流程
String deploymentId = processEngine.getRepositoryService().createDeployment()
.addResourceFromClasspath("swing.jpdl.xml").deploy();
System.out.println("流程發布ID:"+deploymentId);
//啟動一個流程實例
ProcessInstance processInstance = executionService.startProcessInstanceByKey("swing");
System.out.println("流程實例ID:" + processInstance.getId());
//A處理任務
List<Task> taskList_A = taskService.findPersonalTasks("A");
System.out.println("A待處理任務數:" + taskList_A.size());
if(taskList_A.size() > 0){
for(Task task : taskList_A){
System.out.println(task.getId());
taskService.completeTask(task.getId());
}
}
//B處理任務
List<Task> taskList_B = taskService.findPersonalTasks("B");
System.out.println("B待處理任務數:" + taskList_B.size());
if(taskList_B.size() > 0){
for(Task task : taskList_B){
System.out.println(task.getId());
taskService.completeTask(task.getId());
}
}
}
} 一切順利的話就可以看到具體打印了！！關于jbpm的xml專用設計插件，可以看我以前的在Myeclipse8.6安裝JBPM插件
這篇文章。這樣設計好xml就可以發布給jbpm進行工作流處理了。
