jbpm的收文（包括会签的思想）

先定义流程

其中“审核人审核”包括会签的思想
ReceiveAuditAction.java（实现自actionhandle这个接口）

public void execute(ExecutionContext arg0) throws Exception {
Token token = arg0.getToken();  
TaskMgmtInstance tmi = arg0.getTaskMgmtInstance();  
TaskNode taskNode = (TaskNode)arg0.getNode();  
Task task = taskNode.getTask("审核人审核");

String docreceiveId=arg0.getContextInstance().getVariable("docreceiveId").toString();
Docreceive docreceive=docreceiveDAO.findById(Integer.valueOf(docreceiveId));
String auditorid = docreceive.getAudtiors();
String dptid = docreceive.getDpts();
String[] dpt = dptid.split(",");
String value = auditorid;
for(int i=0;i<dpt.length;i++)
{
String strsql = "from TUser as u where u.department.id ='"+ dpt[i]+"' and u.role.roleName like '%内勤'";
List list =userDAO.getSqlresult(strsql);
String [] manager=new String[list.size()];
int j=0;
for (Iterator iter = list.iterator(); iter.hasNext();) {
TUser user = (TUser) iter.next();
manager[j++]=user.getId().toString();
}
tmi.createTaskInstance(task, token).setPooledActors(manager);
}
String[] auditors = value.split(",");
for(int i=0;i<auditors.length;i++)
{
String s = auditors[i];
String[] temp = s.split("-");
String auditor;
if(temp.length==1)
{
auditor = s;
}
else
{
auditor = temp[1];
}
tmi.createTaskInstance(task, token).setActorId(auditor);
}
}
ReceiveAuditAction决定了审核领导和审核部门的执行人
其中tmi.createTaskInstance(task, token).setPooledActors(manager);设定了流程执行人的候选人；而tmi.createTaskInstance(task, token).setActorId(auditor);设定了流程的执行人。

ReceiveAuditEndAction.java也实现了ActionHandler接口
public void execute(ExecutionContext arg0) throws Exception {
String docreceiveId=arg0.getContextInstance().getVariable("docreceiveId").toString();
Docreceive docreceive=docreceiveDAO.findById(Integer.valueOf(docreceiveId));
Token token = arg0.getToken();
TaskMgmtInstance tmi = arg0.getTaskMgmtInstance();
Collection<TaskInstance> unfinishedTasks = tmi.getUnfinishedTasks(token); 
Object variable = arg0.getVariable("selectedTransition");
String selectedTransition;
if (variable == null)
{ 
throw new RuntimeException("Jbpm transition error: user selected transition is null!"); 
}
else
{ 
// 获取当前TaskInstance选择的路径 
selectedTransition = variable.toString(); 
}
//如果用户选择的路径是流程定义中制定的不通过的路径，则自动完成余下所有的会签Task并转到相应路径 
if (selectedTransition.equals("不同意"))
{ 
for (TaskInstance unfinishedTaskInstance : unfinishedTasks)
{ 
// 把被结束的没有完成的TaskInstance的ActorId改为automatic complete 
if(!unfinishedTaskInstance.hasEnded())
{ 
unfinishedTaskInstance.setActorId("automatic complete"); 
unfinishedTaskInstance.end("不同意"); 
} 
}
}
else
{
boolean b = false;
if(unfinishedTasks.size()==0)
{
arg0.getNode().leave(arg0, "同意并返回");
}
}
}
重点是
（1）selectedTransition是在执行流程时定义的jbpmBus.inOpinion("审核", taskid);
public boolean inOpinion(String opinionResult,String tid)
{
JbpmContext jbpmContext=jbpmConfiguration.getCurrentJbpmContext();
if(jbpmContext==null)
{
jbpmContext=jbpmConfiguration.createJbpmContext();
}
try {
    TaskInstance ti=jbpmContext.getTaskMgmtSession().getTaskInstance(Long.parseLong(tid));
    ti.setVariable("selectedTransition", opinionResult);
    ti.end(opinionResult);
    return true;

} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
finally{
jbpmContext.close();
}
return false;
}
"selectedTransition"其实就是当先选择的transition的名字
（2）arg0.getNode().leave(arg0, "同意并返回");
在于一旦所有的审核领导和审核部门都已审核，那么就进入下一个流程了

哈哈，终于说完了，也不知道说的还明白，第一次写博客，敬请原谅！！
