正则表达式Spring数据mongodb存储库 [英] Regular expression Spring data mongodb repositories

问题描述

早上好

我正在尝试使用查询注释将正则表达式与Spring数据mongodb存储库结合起来. 我想要的是在我的mongo文档的一个字符串属性中搜索一个子字符串. 我一直在谷歌和这里寻找，但没有找到任何优雅的东西，我想知道Spring资料库中是否有关于此的官方资料.

I´m trying to combine regular expression with Spring data mongodb repository using Query annotation. What I want is search one substring inside one string attribute of my mongo document. I have been looking in google and here, but I did not find anything elegant, and I was wondering if Spring data has something official about this using the repositories.

致谢.

推荐答案

这似乎是一个老问题，所以也许您已经有了一个解决方案，但是在这里我如何处理同样的问题:

It seems like an old question, so maybe you've already had a solution but here how I handled the same issue :

@Query(value = "{'title': {$regex : ?0, $options: 'i'}}")
Foo findByTitleRegex(String regexString);

使用/?0/表示法将不起作用，因为Spring Data将带引号的String值放置

using the /?0/ notation won't work since Spring Data places a String value with quotes
