简化excel校验提高开发效率

业务背景：上传excel文件进行基础数据校验，然而东西太多写着写着就...自然成了测试的KPI了

解决思路：使用现有的注解处理，原理使用@validate注解原理

直接上干货，一行代码搞定校验：

ValidateUtils.validate(List.of(fieldReq));

仿上传之后用easyexcel解析后生成的实体对象进行测试【此处省略上传解析，工具类待后续文章补充】

    @RequestMapping("/validate")
    public void validate() {
        RuleConfigAddReq ruleConfigAddReq = new RuleConfigAddReq();
        ruleConfigAddReq.setRuleKey("ruleKey");
        ruleConfigAddReq.setFieldName("fieldName");
        ruleConfigAddReq.setFieldDescription("fieldDescription");
        ruleConfigAddReq.setClassName("className");
        ruleConfigAddReq.setClassDescription("classDescription");
        ruleConfigAddReq.setExpression("expression");
        ruleConfigAddReq.setRuleOrder(1);
        FieldReq fieldReq = new FieldReq();
        //
        ValidateUtils.validate(List.of(fieldReq));
    }
