一：导入相应的jar包:
    *注意事项：
    (1).与项目中的jar包不能出现冲突
    (2).版本应一致

jbpm-bpmn.jar
    jbpm-console-form-plugin.jar
    jbpm-console-graphView-plugin.jar
    jbpm-console-integration.jar
    jbpm-console-reports.jar
    jbpm-db.jar
    jbpm-examples-tests.jar
    jbpm-jboss.jar
    jbpm-test-db-tests.jar
    jbpm-tomcat6.jar
    jbpm.jar
    livetribe-jsr223.jar
    mail.jar
    项目已经整合了SSH2，那么只需要在添加：
    jbpm.jar,
    juel-api.jar,
    
    juel-engine.jar,
    jues-impl.jar,
    mail.jar,
    
    livetribe-jsr223.jar即可
    其中下面三个放到tomcat的lib包目录下，因为这三个包会和tomcat的el-api.jar发生冲突，应先注释掉el-api.jar
     Juel-api.jar
     Juel-engine.jar
     Juel-impl.jar
    二：修改配置文件:
    (1).添加jbpm.cfg.xml文件，文件内容如下：
     <import resource="jbpm.default.cfg.xml" />
     
     <import resource="jbpm.businesscalendar.cfg.xml" />
     
     <import resource="jbpm.tx.hibernate.cfg.xml" />
     
     <import resource="jbpm.jpdl.cfg.xml" />
     
     <import resource="jbpm.bpmn.cfg.xml" />
     
     <import resource="jbpm.identity.cfg.xml" />
    (2).因为项目中hibernate.cfg.xml文件与jbpm.hibernate.cfg.xml文件冲突，所以修改hibernate.cfg.xml文件：添加Jbpm所需要的配置文件:
    
     <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" />
    (3).生成JBPM的18张表：
    @Test
    public void createJbpm(){
    ApplicationContext ac = new ClassPathXmlApplicationContext("beans.xml");
    SessionFactory sf = (SessionFactory) ac.getBean("sessionFactory");
    System.out.println("SessionFactory:"+sf);
    }
    三：整合Spring
    (1).调用流程引擎不再使用:
    processEngine processEngine = Configuration.getProcessEngine();
    (2).修改jbpm.cfg.xml文件，与Spring进行整合的文件:
    <?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.spring.cfg.xml" />
      <import resource="jbpm.jpdl.cfg.xml" />
      <import resource="jbpm.bpmn.cfg.xml" />
      <import resource="jbpm.identity.cfg.xml" />
    
      
      
      
    </jbpm-configuration>
    (3).在Spring的配置文件beans.xml中配置ProcessEngine，添加：
    
     <bean id="springHelper" class="org.jbpm.pvm.internal.processengine.SpringHelper">
        <property name="jbpmCfg" value="jbpm.cfg.xml"></property>
     </bean>
     <bean id="processEngine" factory-bean="springHelper" factory-method="createProcessEngine" />
    (4).测试流程引擎对象:
    @Test
    public void testProcessEngine(){
    ApplicationContext ac = new ClassPathXmlApplicationContext("beans.xml");
    ProcessEngine processEngine = (ProcessEngine)ac.getBean("processEngine");
    	System.out.println("PorcessEngine:"+processEngine);
    }
    出现：org.jbpm.pvm.internal.processengine.SpringProcessEngine@ee3dee，表示成功
    (5).使用流程引擎对象:
    在Service层使用：
    @Resource
    private ProcessEngine processEngine;
    
    四：启动Tomcat服务器的配置:
    (1).jbpm使用了el表达式的3个jar包，分别是Juel-api.jar，Juel-engine.jar，Juel-
    impl.jar。这与tomcat的el-api.jar发生冲突
    解决:可将tomcat的lib下删除el-api.jar，添加Juel-api.jar，Juel-engine.jar，
    Juel-impl.jar
    (2).修改hibernate.cfg.xml文件，将:
    <property name="hibernate.dialect">
     org.hibernate.dialect.MySQL5Dialect
    </property>
    修改成为:
    <property name="hibernate.dialect">
    org.hibernate.dialect.MySQL5InnoDBDialect
    </property>
