jbpm4.4整合spring2.5(ibatis与hibernate全整合)

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"?>

	</bean>
	
	<!-- ibatis-spring 配置 -->

			</props>
		</property>
	</bean>

</beans>

 

database.properties:

 

jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.jdbcUrl=jdbc:mysql://localhost:3306/myweb
jdbc.user=root
jdbc.password=pwd


c3p0.initialPoolSize=1
c3p0.minPoolSize=1
c3p0.maxPoolSize=10
c3p0.acquireIncrement=5
c3p0.maxIdleTime=1800
c3p0.maxStatements=0

 

 

 注意：这里会遇到一个类：com.xuyi.support.DynamicDataSource这类实现了多数据源管理。如下：

 

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。

另外如果安装插件有中文乱码问题，或者有控制台乱码问题，可以参考：

 

Eclipse里做JBPM工作流gpd.xml中文乱码问题解决(包括控制台乱码解决) 

这篇文章。

新加spring3.0的配置档一份包含事务AOP处理。
