是否可以将 Query 对象作为 MongoRepository 方法的参数传递？

Question

I create mongodb Query object in service layer, then I call repository method and pass Query to it. I don't want to use annotation @Query. So, repository method should look something like this:

List<Person> findByQuery(Query query, Pageable pageable);

or simply find(...) . But when I build the project, there are errors in tests. It says:

No property 'query' found for type 'Person'

or

No property 'find' found for type 'Person'! Did you mean ''id''?

Obviously, the name of method is incorrect. How should I name the method to make Spring generate code?

Answer 1

As Query is a persistence technology-specific abstraction (in this case MongoDB), it is supposed to be used within the repository. The service layer shouldn't actually need to refer such a type. This means that query methods need to be composed of domain types and either bound to a derived or declared query.

If you want to create the Query instance yourself, the way to go is a custom repository method implementation. How to declare them is described in the reference documentation .
