定义一个ActionHandler：
package com.test;
import org.jbpm.graph.def.ActionHandler;
import org.jbpm.graph.exe.ExecutionContext;
public class MyAction implements ActionHandler
{
private static final long serialVersionUID = 1L;
private String message;
public String getMessage()
{
return message;
}
public void setMessage(String message)
{
this.message = message;
}
public void execute(ExecutionContext executionContext) throws Exception
{
System.out.println(message);
}
}
定义一个流程文件：
<?xml version="1.0" encoding="UTF-8"?>
<process-definition
xmlns="urn:jbpm.org:jpdl-3.1"
name="simple">
<start-state name="start">
<transition name="to_state" to="first">
<action name="action" class="com.test.MyAction">
<message>Going to the first state!</message>
</action>
</transition>
</start-state>
<state name="first">
<transition name="to_end" to="end">
<action name="action" class="com.test.MyAction">
<message>About to finish!</message>
</action>
</transition>
</state>
<end-state name="end"></end-state>
</process-definition>
定义流程驱动类：
package com.test;
import java.io.IOException;
import java.io.InputStream;
import org.jbpm.graph.def.ProcessDefinition;
import org.jbpm.graph.exe.ProcessInstance;
public class Main
{
public static void main(String[] args) throws IOException
{
InputStream stream = Main.class.getResourceAsStream("processdefinition.xml");
ProcessDefinition processDefinition = ProcessDefinition
.parseXmlInputStream(stream);
stream.close();
ProcessInstance instance = new ProcessInstance(processDefinition);
while (!instance.hasEnded())
{
instance.signal();
}
}
}
将jbpm***.jar、commons-logging**.jar和dom4j.jar三个包加入classpath就可以了。
执行结果：
Going to the first state!
About to finish!
