Jbpm4 Environment Construction

1. related development tools and software used.

1) Eclipse IDE for Java EE developers (eclipse 4.2)

2) jbpm4.4

3) mysql5.5

2. Configure The GPD plug-in for the design process in eclipse.

1) GPD plug-in Directory: jbpm-4.4 \ install \ SRC \ GPD \ jbpm-gpd-site.zip

2) install plug-ins: Eclipse menu help --> install new softwore... open the install window; click Add... In the install window to open the Add repository window; click archive...in the Add repositorywindow, select jbpm-gpd-site.zip.

3) after the installation is complete, you will be prompted whether to restart eclipse and choose restart.

3. Configure jbpm runtime locations.

1) eclipse menu window --> preferences --> JBoss jbpm --> runtime locations

2) In the runtime locations window, click Add... to open the Add location window. Name: name, for example, jbpm4.4; Location: select the unzip installation directory of jbpm4.4.

4. Implement first jbpm4 using unit tests.

1) create a Java project named firstjbpm4.

2) add all jar files under jbpm-4.4 \ jbpm. jar and jbpm-4.4 \ Lib to the classpath path of the project. (Or configure all jbpm4.4 jar files as a user library and then directly reference them in the Project)

3) add jbpm. cfg. XML, jbpm. hibernate. cfg. xml and logging. properties under the jbpm-4.4 \ examples \ src directory to the src directory of the project.

4) The firstjbpm4 project structure is as follows.

 

5) modify the jbpm. hibernate. cfg. xml file and configure database information.

<? 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">  
 
 
 
6) Create a database named jbpm4 in MySQL.
 
create database jbpm4 default character set utf8;
 
 
 
7) on the project name, right-click New --> source folder and name it process. Process and SRC are at the same level. process definition files are stored in process.
 
8) design the leave process definition file. Create a package named leave under process, and right-click New --> jbpm process definition on leave and name it leave.
 
 
9) Draw a flowchart and use assignee to allocate corresponding task handling personnel.
 
 
The leave. jpdl. xml file is as follows:
 
 
<? XML version = "1.0" encoding = "UTF-8"?> <Process name = "leave" xmlns = "http://jbpm.org/4.4/jpdl"> <start name = "start1" G = "303,8, 48, 48 "> <transition name =" to submit an application "to =" submit an application "G ="-67, -20 "/> </start> <End name =" end1 "G =" 303,340, "/> <Task Name =" submit an application "G =" 281,88, 92,52 "assignee =" [employee] Xiao Li "> <transition name =" to department manager approval "to =" department manager approval "G ="-91, -20 "/> </task> <Task Name =" department manager approval "G =" 281,172, 92,52 "assignee =" [department manager] "> <transition name =" to General Manager approval "to =" General Manager approval "G ="-79, -20 "/> </task> <Task Name =" General Manager approval "G =" 281,256, 92,52 "assignee =" [General Manager] ZHANG Zong "> <transition name =" to end1 "to =" end1 "G ="-45, -20 "/> </task> </process>
 
 
The entire process is: [employee] Xiao Li applies -- "[department manager] Li Zong approves --" [General Manager] ZHANG Zong approves.
 
10) unit test code.
 
 
Package CN. luxh. jbpm4; import Java. util. list; import Org. jbpm. API. configuration; import Org. jbpm. API. processengine; import Org. jbpm. API. processinstance; import Org. jbpm. API. task. task; import Org.

GETID ());}}}
