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

Java Eclipse C/C++ jBPM Go 29172 次浏览

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"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"

	<bean id="processEngine" factory-bean="springHelper"  factory-method="createProcessEngine" />
	
	<!-- dataSourceproxy 配置代理管理事务 -->
	<bean id="dataSource"

		p:acquireIncrement="${c3p0.acquireIncrement}" p:maxIdleTime="${c3p0.maxIdleTime}"
		p:maxStatements="${c3p0.maxStatements}" lazy-init="true" />
	

	<!-- hibernate-spring 基本配置 -->

                <prop key="hibernate.hbm2ddl.auto">update</prop>

		</property>
		<!-- 使用TransactionAwareDataSourceProxy管理事务与ibatis处于同一事务管理下 -->
		<property name="useTransactionAwareDataSource" value="true"></property>
	</bean>
	
	<!-- ibatis-spring 配置 -->
	<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">

		</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。
