handler类

public class MyDecision implements DecisionHandler {

private static final long serialVersionUID = 1L;

@Override
public String decide(OpenExecution execution) {
String to = execution.getVariable("to").toString();

if(to.equals("组长")){
return "到组长";
}else if (to.endsWith("科长")){
return "到科长";
}else{
return "到主任";
}
}

}

创建流程实例
Map<String,Object> map = new HashMap<String,Object>();
map.put("to", "主任");
ProcessInstance processInstance = executionService.startProcessInstanceByKey("decision", map);
print("流程实例ID",processInstance.getId());
