Which class does the parsing and query building in spring data JPA repository?

Question

我已经在 spring 文档“Spring Data 存储库基础结构中内置的查询构建器机制”中阅读了这一行，谁能告诉我这个查询构建在 spring 中到底是哪个类？

Answer 1

You should look at org.springframework.data.jpa.repository.query.JpaQueryCreator and also at org.springframework.data.jpa.repository.query.PartTreeQuery . The former does the actual construction of the query. The latter holds all the pieces together: The parsed PartTree containing the structure of the method name, arguments, the processing of results and so on.
