jbpm4.4整合spring2.5(ibatis与hibernate全整合)
4
搞了好几个小时总算运行成功了，记录一下吧。
首先下载jbpm4.4，解压出来备用。然后工程自己导入hibernate和spring的jar包以及配置文件。好了可以开始整合了！
整合的先后顺序是关键，下面按照顺序一步一步来设置:
1.首先jbpm是依赖数据库的，所以可以先创建数据库，我是mysql数据库，所以到jbpm-4.4\install\src\db\create中找到jbpm.mysql.create.sql创建文件导入mysql执行！
2.设置spring中hibernate的配置:
可以参考:jbpm-4.4\install\src\cfg\hibernate\spring中的mysql.hibernate.cfg.xml(具体见下面的spring配置文件applicationContext.xml)
3.设置事务，这里由于hibernate和ibatis必须用一个事务，所以使用了TransactionAwareDataSourceProxy来管理事务。(具体见下面的spring配置文件applicationContext.xml)
4.配置默认jbpm的cfg文件，在classpath下创建一个jbpm.cfg.xml,内容如下：
<?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。(具体见下面的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，这里注意一下，可能有的朋友之后运行还会有错误如下：
java.lang.NoSuchMethodError: antlr.collections.AST.getLine()I
这是因为struts2的anltr-2.7.2.jar过旧导致的，我们为了省掉麻烦这里最好直接把struts2的antlr.jar去掉(windows---preferences---在文本框中搜索struts 2(中间有空格)---选择struts 2---选择antlr---remove)，然后重新到发布到服务器的lib目录下删除anltr-2.7.2.jar即可。
7.成功的关键就是applicationContext.xml了，这里把这个关键配置贴出来！
<?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();
}
// ---------------------------------------------------------------------------------------------------
/**
* 设置数据源路径
*/
public static void setRoute(String route) {
if (route==null || route.equals("")){
route = "dataSource";
}
local.set(route);
}
}
8.终于可以开始测试了，先创建一个发布用的xml放入classpath：
测试用的流程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> 然后写一个测试类进行测试: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();
//发布流程
String deploymentId = processEngine.getRepositoryService().createDeployment()
.addResourceFromClasspath("swing.jpdl.xml").deploy();
System.out.println("流程发布ID:"+deploymentId);
//启动一个流程实例
ProcessInstance processInstance = executionService.startProcessInstanceByKey("swing");
System.out.println("流程实例ID:" + processInstance.getId());
//A处理任务
List<Task> taskList_A = taskService.findPersonalTasks("A");
System.out.println("A待处理任务数:" + taskList_A.size());
if(taskList_A.size() > 0){
for(Task task : taskList_A){
System.out.println(task.getId());
taskService.completeTask(task.getId());
}
}
//B处理任务
List<Task> taskList_B = taskService.findPersonalTasks("B");
System.out.println("B待处理任务数:" + taskList_B.size());
if(taskList_B.size() > 0){
for(Task task : taskList_B){
System.out.println(task.getId());
taskService.completeTask(task.getId());
}
}
}
} 一切顺利的话就可以看到具体打印了！！关于jbpm的xml专用设计插件，可以看我以前的在Myeclipse8.6安装JBPM插件
这篇文章。这样设计好xml就可以发布给jbpm进行工作流处理了。
