获取流程历史记录
public List<WfHistoricProcess> findHistoricProcessList(String processDefinitionKey) {
       List<HistoricProcessInstance> list = historyService.createHistoricProcessInstanceQuery().finished()
               .processDefinitionKey(processDefinitionKey).orderByProcessInstanceEndTime().desc().list();
       List<WfHistoricProcess> historicProcessList = new ArrayList<WfHistoricProcess>(list.size());

           historicProcess.setVariablesMap(variablesMap);
           historicProcessList.add(historicProcess);
       }
       return historicProcessList;
   }

其中WfHistoricProcess：
public class WfHistoricProcess implements Serializable {
   private static final long serialVersionUID = -8437224215907962601L;

   private HistoricProcessInstance process;
   private Map<String, Object> variablesMap;

   public HistoricProcessInstance getProcess() {
       return process;
   }

   public void setProcess(HistoricProcessInstance process) {
       this.process = process;
   }

   public Map<String, Object> getVariablesMap() {
       return variablesMap;
   }

   public void setVariablesMap(Map<String, Object> variablesMap) {
       this.variablesMap = variablesMap;
   }
}
