Spring与JBPM整合

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：

01 xml version="1.0" encoding="UTF-8"?>
02
03 <jbpm-configuration>
04
05   <import resource="jbpm.default.cfg.xml" />
06   <import resource="jbpm.businesscalendar.cfg.xml" />
07
08   <import resource="jbpm.tx.spring.cfg.xml" />
09   <import resource="jbpm.jpdl.cfg.xml" />
10   <import resource="jbpm.bpmn.cfg.xml" />
11   <import resource="jbpm.identity.cfg.xml" />
12
13
14
15
18
19 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)

1
2     <bean id="springHelper" class="org.jbpm.pvm.internal.processengine.SpringHelper"/>
3     <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！

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：

01 package com.xuyi.support;
02
03 import org.springframework.jdbc.datasource.lookup.AbstractRoutingDataSource;
04
05 public class DynamicDataSourceextends AbstractRoutingDataSource {
06
07     private static ThreadLocal local = new ThreadLocal();
08
09     @Override
10     protected Object determineCurrentLookupKey() {
11         return local.get() == null ?"dataSource" : local.get();
12     }
