            maxResults(params.max?params.max.toInteger():paramsService.pageMax)
            firstResult(params.max?params.offset.toInteger():0)

主要是加了这一句firstResult(params.max?params.offset.toInteger():0)后无法统计总记录数

                    eq('tags', params.tags);
                }
                if (params.keyword){
                    or {
                        like("title","%${params.keyword}%")
                        like("brief","%${params.keyword}%")
                    }
                }
                if (params.postTime) {
                    DateTime beginDate = new DateTime(params.postTime + '-01');
                    DateTime endDate = beginDate.plus(0, 1, 0, 0, 0, 0, 0, DateTime.DayOverflow.FirstDay)
                    ge("postTime", DateUtil.stringToDate(beginDate.toString()))
                    le("postTime", DateUtil.stringToDate(endDate.toString()))
                }
            }
            maxResults(params.max?params.max.toInteger():paramsService.pageMax)
            firstResult(params.max?params.offset.toInteger():0)
            order("id", "desc")
        }
        def searchClosure1 = {

                    }
                }
                if (params.postTime) {
                    DateTime beginDate = new DateTime(params.postTime + '-01');

                    le("postTime", DateUtil.stringToDate(endDate.toString()))
                }
            }
        }
        def c = Post.createCriteria()
        def results = c.list(searchClosure)
        c = Post.createCriteria()
        def resultCount = c.count(searchClosure1)

 是不是grails2.2的问题？
