JBPM and Spring Integration

Spring with the Jbpm the Integration

1, the necessity of integration:

Business data operations and process operations in the process need to be implemented in the same transaction

For example: leave process--leave the person to submit a leave request, the process jumps to the next node task (JBPM data ) record the leave person information to the user table ( Business Data )

an operation that may involve both JBPM data and business data, if used with two transactions, can lead to inconsistencies in business-to-process data.

2, integration diagram

Integration principle:

( 1 ) using Spring Container IOC provided by beanfactory function Initialization JBPM of the Configuration .

( 2 ) to make business data and JBPM Public sessionfactory .

3,the core ofSpring and Jbpm integration:

(1) generated by the Spring container processengine

(2)Jbpm 's affairs are given to spring processing

4, integration steps

* Import JBPM Jar Package

* Delete the jar packages for DB and Hibernate

* Create a configuration file under Config

config/jbpm

Jbpm.cfg.xml

Jbpm.hibernate.cfg.xml

* in Jbpm.cfg.xml file

<import resource= "Jbpm.tx.hibernate.cfg.xml"/>

instead     

<import resource= "Jbpm.tx.spring.cfg.xml"/>

Unification is handled by spring, and by the configuration on the right it is possible to open a transaction by creating a new session

* in Jbpm.hibernate.cfg.xml file

* Connection Configuration of database

<propertyname= "Current_session_context_class" >thread</property>

This line of configuration cannot be written and cannot be retrieved from the current thread

* Map file for the table of OA project itself

* Mapping file for JBPM tables

* Spring configuration file

* Path modification of hibernate configuration file

<bean id= "Sessionfactory" class= "Org.springframework.orm.hibernate3.LocalSessionFactoryBean" >       < Property name= "Configlocation" >           <value>classpath:jbpm/jbpm.hibernate.cfg.xml</value>       </property> </bean>

* Let Spring produce processengine

<bean id= "Springhelper" class= "Org.jbpm.pvm.internal.processengine.SpringHelper" >      <property name= " Jbpmcfg "value=" Jbpm/jbpm.cfg.xml "></property> </bean> <bean id=" Processengine "factory-bean=" Springhelper "      factory-method=" Createprocessengine "/>

Note the path to the Jbpm.cfg.xml configuration file

5, Summary:

JBPM with the SSH Integration--Let Spring Manage Builds Processengine , let Hibernate Build JBPM entity database tables.
