Spring Data REST:MongoDB存储库的自定义查询

问题描述：

I am trying to create a custom query from the Spring guide : Accessing MongoDB Data with REST according to the Reference 4.4 Custom Implementations. But my custom method is not available from the repository's REST interface (/user/search).

(例如，浏览器无法找到localhost:8080/user/search/GetByKidsAge?age = 1)

(e.g. Browser is unable to find localhost:8080/user/search/GetByKidsAge?age=1)

有人可以帮我解决这个问题并给我一些建议吗? 非常感谢！！

Could someone help me to figured this out and give me some suggestions? Thanks a lot !!

下面是我的代码:

UserRepositoryCustom.java

public interface UserRepositoryCustom {     

    public List<User> GetByKidsAge(@Param("age") int age);
}

UserRepositoryImpl.java

public class UserRepositoryImpl implements UserRepositoryCustom {

    @Override
    public List<User> GetByKidsAge(int age) {

        return /*perform query*/;

    }
}

UserRepository.java

@RepositoryRestResource(collectionResourceRel = "user", path = "user")
public interface UserRepository extends MongoRepository<User, String>, UserRepositoryCustom {

        List<User> findByLastName(@Param("name") String name);  
}

答

这是设计使然.一旦您开始手动实现存储库方法，我们就无法知道GET还是POST是正确的HTTP方法，因为执行是否等幂取决于您如何实现它.

This is by design. As soon as you start implementing a repository method manually we cannot know whether GET or POST is the right HTTP method as whether the execution is idempotent depends on how you implement it.

因此，方法是实现自定义控制器，并使用适当的HTTP方法公开这些方法.就是说，我们的跟踪器中有一个 ticket ，提供了定义这些方法的方式的方法也要暴露出来.

So the way to go would be implementing a custom controller and expose those methods using the adequate HTTP method. That said, there's a ticket in our tracker to provide means to define the way these methods should be exposed as well.
