后台controller：
 @RequiresPermissions("sys:menu:edit")
    @ResponseBody
    @RequestMapping("/deletebatch")
    public String deletebatch(@RequestParam("idList[]") List<String> objs,ModelMap modelMap, HttpServletRequest request) throws Exception {
     String retStr = "error";
     try{
   menuService.removeMulti(objs);
   retStr = "success" ;
     }catch(Exception e) {
      logger.info(e.getMessage());
     }
     return retStr;
    }

后台service：

 @CacheEvict(value="defaultCache",allEntries=true)
 public void removeMulti(List<String> objs) {
  
  BasicDBList basicDBList=new BasicDBList();
  for(String id : objs) {
   basicDBList.add(new BasicDBObject("id",id));
  }

        DBObject obj =new BasicDBObject();
        obj.put("$or", basicDBList);
        Query query=new BasicQuery(obj);

  mongoTemplate.remove(query,Menu.class);
 } 

如果不跳转，应该把ajax里面的dataType改成html ，json时返回不正确
