tk.mybatis Example 多个or条件拼接

//需要的查询条件为 a and (b or c or d) 可以转换为 （a and b) or (a and c) or (a and d)
//第一种方式 使用andEqualTo拼接条件

    //1.活动有效期限起在查询日期起止范围之内
    //2.活动有效期限止在查询日期起止范围之内
    //3.活动有效期限起止在查询日期起止范围之内符合1，2情况
    //4.查询开始日期起止包含在活动有效期限起止之内
    if (StringUtils.isNotBlank(request.getValidStart()) && StringUtils.isNotBlank(request.getValidEnd())) {

//第三种方式 可以直接在CustomMapper文件里面用Mybatis方法写查询sql
