项目中执行lock.unlock()出现java.lang.IllegalMonitorStateException

项目中代码，这段代码是判断excel是不是正在导出中，并发量只允许为1，因为excel导出很占cpu资源

@RequestMapping("excelOrderExportCheck.json")
  @ResponseBody
  public AjaxObj excelOrderExportCheck(){
  AjaxObj ajaxObj=new AjaxObj();
  //防止重复excel导出
  long exportTime = orderCarMallUtil.getExportRedisTime(REDISNAME);
    if(lock.tryLock() //这里尝试获取锁){
        ajaxObj.setResult(AjaxObj.SUCCESS); 
        ajaxObj.setMsg("exportTime="+exportTime+",System.currentTimeMillis()-exportTime="+(System.currentTimeMillis()-exportTime));
        }else{
            ajaxObj.setMsg("有人正在导出中,请不要重复导出");
            ajaxObj.setResult(AjaxObj.FAILD);
        }
        return ajaxObj;
    }

        }
        finally{
           lock.unlock();//导出完之后给上面代码获取到的锁解锁
        }
    }

报出如下异常：

看了下源码是在155行抛出的异常：

执行lock.unlock()执行源码会判断当前线程有没有获取到锁，如果没获取到锁就解锁会
抛出 new IllegalMonitorStateException();

所以我的问题是当前线程加的锁只能在当前线程中进行解锁，不能再其他线程中进行解锁。
