myeclipse8,5搭建jbpm4的开发环境

jbpm版本：4.3
IDE:myeclipse8.5
DB:mysql5.0


1:myeclipse中安装jbpm
a:解压jbpm4.3
b:打开myeclipse8.5---->选择Help菜单---->选择Myeclipse Configuration Center------>打开第三个选项卡SoftWare----->选择右上角add site---->选折add form archive file-----》找到${jbpm_home}\install\src\gpd 目录下找到jbpm-gpd-site.zip即可！name随便输入即可（比如我输入 jpd）！这样下面就看到多一个jpd(部分过程看下图 )

c:一个一个选中jpd下面的文件，点击右击 add to profile即可！
d: 点击右上角apply change按钮即可！
2:生成jbpm数据库表(我这里以安装mysql为列)
a:先打开mysql数据库新建一个数据库比如jbpm(create database jbpm);
b:打开${jbpm_home}\install\src\db\create 下面，找到mysql的表脚本！
c:全部复制过来粘贴到mysql命令行上（当然也可以source ***.sql方式），

3: helloWorld程序

新建一个java project 项目名称为helloJbpm
a:首先导入相应的jar包(导入$(jbpm_home)\lib目录下面的所有jar包和$(jbpm_home}下面的jbpm.jar包到项目中去)
b:导入配置文件（导入${Jbpm_home}\examples\src目录下面的所有配置文件到项目导入src目录下面,然后修改jbpm.hibernate.cfg.xml里面的driver，用户名，密码，数据库名(可以参考${JBPM-home}\install\jdbc目录下面的mysql.properties文件)）
c:设计流程文件
选择new-->jbpss jbpm--->jbpm4 process definition文件即可

xml代码：

 
<?xml version="1.0" encoding="UTF-8"?>
<process name="hello" xmlns="http://jbpm.org/4.0/jpdl">
   <start g="112,33,88,48" name="start1">
      <transition g="-77,-17" name="to family168" to="family168"/>
   </start>
   <state g="122,293,92,52" name="family168">
      <transition g="-47,-17" name="to end1" to="end1"/>
   </state>
   <end g="122,400,48,48" name="end1"/>
</process>

d:写一个测试类

package cn.ljz.jbpm;

import java.util.List;
import org.jbpm.api.Configuration;
import org.jbpm.api.Execution;
import org.jbpm.api.ExecutionService;
import org.jbpm.api.ProcessDefinition;
import org.jbpm.api.ProcessEngine;
import org.jbpm.api.ProcessInstance;
import org.jbpm.api.RepositoryService;
import org.junit.Before;
import org.junit.BeforeClass;
import org.junit.Test;

public class HelloWorldTest {
    private static ProcessEngine processEngine;
    private static  ExecutionService executeServices ;

	@BeforeClass
	public static void setUpBeforeClass() throws Exception {
		processEngine = Configuration.getProcessEngine();//通过单列模式获得流程引擎
		executeServices = processEngine.getExecutionService();
	}

	@Before
	public void setUp() throws Exception {
	}

    @Test
	public void testDeployProcess(){
    	//RepositoryService功能：主要对流程文件进行发布，查看，删除等！
       RepositoryService  repositoryService = processEngine.getRepositoryService();
    	//因为helloword.jpdl.xml文件在  classpath目录下就可以直接这样写，如果不在的话应该加上包名
    	//返回已经发布的流程的id
    	String processId = repositoryService.createDeployment().addResourceFromClasspath("helloworld.jpdl.xml").deploy();
    	//查看已经发布流程的列表
        List<ProcessDefinition> list = repositoryService.createProcessDefinitionQuery().list();

        System.out.println("已经发布的流程数量为:"+list.size());
    	for(ProcessDefinition pd:list){
    		System.out.println("发布流程的名称:"+pd.getName()+",发布流程id"+pd.getId());    		
    	}
    	repositoryService.createProcessDefinitionQuery();
    	//根据流程id来删除已经发布的流程
    	//repositoryService.deleteDeployment(processId)
    	//repositoryService.deleteDeploymentCascade("processId");
    	//repositoryService.suspendDeployment(processId);这个等价于删除一个流程
    	//System.out.println("已经发布的流程数量为:"+repositoryService.createProcessDefinitionQuery().list().size());


    } 
   @Test
    public void testProcessInstance(){	   

    	ProcessInstance processInstance = executeServices.startProcessInstanceByKey("helloworld");
    	List<ProcessInstance> list = executeServices.createProcessInstanceQuery().list();
    	for(ProcessInstance pi:list){
    		System.out.println("流程实例名称:"+pi.getName()+",流程实例key:"+pi.getKey()+",流程实例version:"+pi.getState()+":");
    	}
    	//结束流程实例 
        //executeServices.endProcessInstance(processInstance.getId(), "cancel");
        //删除流程实例
        //executeServices.deleteProcessInstance(processInstance.getId());
        //System.out.println(executeServices.createProcessInstanceQuery().list().size());
    	System.out.println(processInstance.isActive("state1"));
    	executeServices.signalExecutionById(processInstance.getId());


    }




}

小小解释：执行发布流程文件的时候，可以查看jbpm4_lob,jbpm4_deployment,jbpm4_deployprop,jbpm4_property表多了记录！
