请看代码哪有错误，创建transition 成功 ，执行成功却不跳转。
ProcessEngine processEngine=Constants.getProcessEngine();
EnvironmentFactory environmentFactory = (EnvironmentFactory)processEngine ;
RepositoryService repositoryService = processEngine.getRepositoryService();
ExecutionService executionService = processEngine.getExecutionService();
TaskService taskService = processEngine.getTaskService();
TaskImpl task = (TaskImpl) taskService.getTask(taskId);
Execution execution = executionService.findExecutionById(task.getExecutionId());
EnvironmentImpl env=null;
try {
env = environmentFactory.openEnvironment();
ProcessDefinitionImpl processDefinition = (ProcessDefinitionImpl)repositoryService.createProcessDefinitionQuery().processDefinitionId(execution.getProcessDefinitionId()).uniqueResult();
//取得当前流程的活动定定义
ActivityImpl sourceActivity = processDefinition.findActivity(taskName);
//取得目标的活动定义
ActivityImpl destActivity=processDefinition.findActivity(destName);
//为两个节点创建连接
TransitionImpl transition = sourceActivity.createOutgoingTransition();
transition.setName(destName);
transition.setDestination(destActivity);
sourceActivity.addOutgoingTransition(transition);
//将流程指定要新建的transition中
processEngine.getExecutionService().signalExecutionById(processEngine.getTaskService().getTask(taskId).getExecutionId(), transition.getName());
System.out.println("sourceActivity.getName() = "+sourceActivity.getName());
System.out.println("destActivity.getName() = "+destActivity.getName());
Map<String, Object> map = new HashMap<String, Object>();
taskService.completeTask(taskId, destName,map);
}catch(Exception ex){
ex.getMessage();
}finally{
env.close();
}
