I am using spring-data-couchbase , but the Query creation from method names is not work. following is my code:
spring-couchbase.xml

</beans:beans>
Repository:
public interface CommentRepository extends PagingAndSortingRepository<CommentDoc, String> {
public Page<CommentDoc> findByUserId(String userId, Pageable pageable);
}
Domain:
@Document
@Data
public class CommentDoc {
@Id
private String id;
/**
* 话题
*/
@Field
private String topicId;
/**
* 用户ID
*/
@Field
private String userId;
}
Test:
@Test
public void testFindByC1() {
Pageable pageable = new PageRequest(0, 10);
Page<CommentDoc> comments = commentRepository.findByUserId("user01", pageable);
for(CommentDoc commentDoc : comments) {
logger.debug("doc: {}", commentDoc);
}
}

Please someone help me! How can I resolve it.

I'm new to this, but just went through it. The Couchbase stuff doesn't seem to support everything offered in the other Spring Data repositories.
You have to add a production view called commentdoc/byUserId (in development view design document name = commentdoc and viewname = byUserId). Don't forget to publish. Something like (fix classname):
function (doc, meta) { if(doc._class == "com.david.XXX.CommentDoc" && doc.userId){ emit(doc.userID, null); } }Change your repo signature from String userId to Query userId
Pass a Query object. Something like:
Query query = new Query(); query.setKey(ComplexKey.of("useridofinteres=")); commentRepository.findByUserId(query, pageable);Full Details Here.
