elment cascader 级联去除圆圈点击文字选中

效验单个组件输入

  checkPhone(rule, value, callback) {
                if (value) {
                    let phone = /^1[3|4|5|6|7|8|9][0-9]\d{8}$/;
                    if (!phone.test(value)) {
                        
                        callback(new Error('请输入正确的手机号码'));
                    } else {
                        callback();
                    }
                }
                callback();
            },

 java字符串按照逗号转成数组

List<String> attachNameList = Arrays.stream(attachName.split(",")).collect(Collectors.toList());

 正则

包含0的正整数
  /^[0-9]\d*$/
正整数限1位小数
/(^[1-9]([0-9]{0,0})?(\.[0-9]{1})?$)|(^(1){1}$)|(^[0-9]\.[1-9]{1}?$)/
五位整数,最多保留二位小数
/(^[1-9]([0-9]{1,5})?(\.[0-9]{1,2})?$)|(^(1){1}$)|(^[0-9]\.[1-9]([1-9])?$)/

 mybaits-puls拼接sql

   //拼接sql
        StringBuffer applySql = new StringBuffer();
        //多选类型
        List<String> types = checkTemplateReq.getTypes();
        //mysql逗号函数查询 拼接sql
        if (!CollectionUtils.isEmpty(types)){
            for (int i = 0; i< types.size();i++){
                if (i == 0 ){
                    applySql.append("(find_in_set("+types.get(i)+", type)");
                }else if (i != 0){
                    applySql.append(" or find_in_set("+types.get(i)+", type)");
                }
            }
            applySql.append(")");
            wrapper.apply(applySql.toString());
        }

find_in_set("1", type) mysql按照逗号分割查询 多个用or

 优化批量新增（plus的运行时间是并发流二倍）

        StopWatch stopWatch = new StopWatch();
        stopWatch.start();
        List<Test1> testList = new ArrayList<Test1>();
        for (int i = 0; i < 5000; i++) {
            Test1 test = new Test1();
            test.setName(String.valueOf(i));
            testList.add(test);
        }
        List<List<Test1>> split = ListUtil.split(testList, 1000);
        split.stream().parallel().forEach(test1Mapper::saveBatch);
//        test1Mapper.saveBatch(testList);
        stopWatch.stop();
        System.out.println(String.format("Total time：%d ms", stopWatch.getTime()));

 for循环时定义index，index.getAndIncrement每次+1

AtomicInteger index = new AtomicInteger(1);
  list.stream().forEach(
                    e ->{
                        TestSupportUnitExport export = new TestSupportUnitExport();
                        export.setSerialNumber(index.getAndIncrement());
                        BeanUtils.copyProperties(e,export);
                        export.setScale(EnterpriseScaleEnum.getCodeByMsg(e.getScale()));
                        export.setSecretRelMeghan(CheckConfidentEnum.getCodeByMsg(e.getSecretRelMeghan()));
                        exportList.add(export);
                    }
            );
