本文介绍JBPM流程引擎的部署与管理方法，包括使用Hibernate进行数据库配置、流程定义的部署方式及流程定义的查询与删除操作。

jbpm.hibernate.cfg.xml

<?xml version="1.0" encoding="utf-8"?><!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory> 
<property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/jbpmdemo</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.connection.password">root</property> 
<property name="hibernate.show_sql">true</property>
<property name="hibernate.hbm2ddl.auto">update</property> 
<mapping resource="jbpm.repository.hbm.xml" />
<mapping resource="jbpm.execution.hbm.xml" />
<mapping resource="jbpm.history.hbm.xml" />
<mapping resource="jbpm.task.hbm.xml" />
<mapping resource="jbpm.identity.hbm.xml" />
</session-factory>
</hibernate-configuration>

通过hibernate生成表的测试代码:

package com.xjz.jbpm.db;

import org.hibernate.cfg.Configuration;
import org.junit.Test;

public class CreateDB {

@Test
public void test(){
Configuration configuration = new Configuration();
configuration.configure("jbpm.hibernate.cfg.xml");
configuration.buildSessionFactory();
}
}

JBPM4.4的API测试代码:

package com.xjz.jbpm.pd;

import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.List;
import java.util.zip.ZipInputStream;

import org.jbpm.api.Configuration;
import org.jbpm.api.Deployment;
import org.jbpm.api.ProcessDefinition;
import org.jbpm.api.ProcessEngine;
import org.junit.Test;

/**
 * 流程定义管理
 * 	1.流程定义

 * 	3.查询
 * 		查询所有的流程定义
 * 		根据deploymentId查询流程定义
 * 		根据pdid查询流程定义
 * 		根据pdkey查询流程定义
 * 	4.删除
 * 	5.查看流程图

public class PDManager {
	/**

	 * 				langid 语言版本 jpdl-4.4
	 * 				pdid	pdkey-version
	 * 				pdkey	流程定义名称
	 * 					一般情况下pdkey objname_的值是一样的
	 * 				pdversion	版本号
	 * 					如果pdkey没有发生改变,每部署一次,版本号加1
	 * 					如果pdkey发生改变,则是一个全新的名称,所以版本号应该从1开始计算
