问题 I am getting an error when using an Oracle DB and Spring Data . The error is: ORA-00942: table or view does not exist The cause of this error is that the user I am connecting with does not have access to the tables in the schemas I wish to connect to. I read that 2 fixes to this are to create synonyms in my database or to specify the schema that each entity/table belongs to. I am going to try the Schema approach first. How do I do so? My example entity below, a Dog in the Vet Schema: @Entity

问题 I want to save a null value to a document with a Spring Data Repository. So someEntity below is an object with a property set to null in java. ... repository.save(someEntity); ... Spring will save this as undefined, meaning the property of the document is not set to null. In our use case, we treat null as a proper value. How can you solve this without overriding the save() method in the repository? 来源： https://stackoverflow.com/questions/27187749/save-null-value-with-spring-repository-to

问题 I am getting unwanted query log from spring neo4j like following 25-08-2018 23:47:07.597 [restartedMain] INFO o.n.o.d.bolt.request.BoltRequest.executeRequest - Request: MATCH (n:`OntoCategory`) WHERE n.`name` = { `name_0` } WITH n RETURN n,[ [ (n)-[r_h1:`HasSynonym`]->(o1:`OntoSynonyms`) | [ r_h1, o1 ] ] ], ID(n) with params {name_0=Breakfast Items} 25-08-2018 23:47:07.610 [restartedMain] INFO o.n.o.d.bolt.request.BoltRequest.executeRequest - I am using following logging properties in my

问题 I am using SpringData's repository. If I try to delete an entity via an ID which does not exist or never existed it throws an exception. Since I do not want to check whether the entity exists before I delete it, it would be nice that it would fail silently. It would make it easier because the observable behavior is the same - after the call the entity does not exists anymore. Whether it has been deleted or never existed, I do not care. Is there a way to modify default behavior of delete

I am facing an issue of null transaction manager. Here's my interface : public interface SearchRepositoryCustom { Iterable<Movie> searchByCriteria(); } Here's my custom repo
