elasticsearch spring data @query annotation

Question

我试图在elasticsearch spring数据中使用@query注释来进行复杂的查询，但当我尝试以下简单查询时，我得到了错误

@Query(value="{'bool':{'must':{'field':{'name':?0}}}}")
Segment findByName(String name);

Answer 1

在@Query注释中，您只需要使用转义双引号而不是单引号：

@Query(value="{"bool":{"must":{"term":{"name":"?0"}}}}")
Segment findByName(String name);

还要注意，我已经用term替换了field（或者match也是可能的），因为field不是一个有效的查询。
