问题 I would like to be able to do some data manipulation when documents are updated or created in Couchbase. Documents can arrive in our database either via Sync Gateway or our own code which streams data in from an http service. It would be great to have one place where I can intercept all updates. We are running a Spring Boot REST API against this data so this would be the good place to have the interceptor/listener. Either way my preference would be for a Java solution.

问题 Is there a way to achieve @Id and @Field on the same variable of a @Document so the variable is also saved inside the document? I'm trying to preserve the data I'm importing as much as I can, even though I get the design practices followed by the developers. 回答1: The @Id annotation will take priority over @Field, so no the id cannot be persisted as both document ID and value inside the document.

问题 I want to make a filterable list of my UserTask entity with the QueryDslPredicateExecutor interface, so the parameters given in the query string will be autoprocessed into a Predicate.

问题 I am using Spring couchbase JPA and trying to fetch documents by giving a list of keys. My repository structure looks something like public interface EmployeeRepo extends CouchbasePagingAndSortingRepository<Employee, String>, EmployeeCustomRepo { I have a list of employee ids to search for and fetch the corresponding document. I tried using the method from curdRepository public List<Employee> findAllById(List<String> empIds) { return employeeRepo.findAll(empIds); } But I get exception as::

问题 So, I was trying to find a way to remove/rename( and change the fields value ) the _class field from the document generated by spring data couchbase as the document is going to be stored by one service and in all likeliness be consumed by someone totally different.
