问题 I'm trying to get Spring Data Auditing to work in my Spring 3.2.8 / Spring Data 1.5 / Hibernate 4 project. As per the Spring Data Auditing docs, I've added the @CreatedBy , etc annotations to my entities, created by AuditorAware implementation, and instantiated it from within my JavaConfig. However, it never seems to fire. I find the docs a little confusing. It appears that the JavaConfig entry replaces the xml entry, but I am not sure. I don't currently have any orm.xml file in my

问题 What is the typical use case code that shows the difference between those two annotations - meaning the @RestController and the @RepositoryRestController - ? 回答1: According to the annotation the RepositoryRestController is a way to provide custom controllers that still take advantage of spring data rest functionality http://docs.spring.io/spring-data/rest/docs/current/reference/html/#customizing-sdr.overriding-sdr-response-handlers Sometimes you may want to write a custom handler for a

问题 Application depends on a number of spring data projects including Neo4j, Solr and Jpa. I recently had to update spring-data-solr to Snapshot-3.0.0.M1 (to eliminate another dependency conflict). I think one of the transitive dependency is causing a conflict with neo4j. If I remove spring-neo4j from project, error (see below) seem to go away. I have a attached a sample project that recreates the issue. Run Test Class AccountServiceJpaTester.testSaveAccount() Download sample project from here

问题 I have a SQL database where primary keys are UUIDs, but the canonical string representation of a UUID is very long, and I would like to use a shortened version (Base58) in my URLs. Spring Data's DomainClassConverter will convert MVC request parameters or path variables into domain objects, but I want to be able to modify the resolved ID before it's passed to the repository. The default SpringDataWebConfiguration creates a DomainClassConverter using a FormattingConversionService supplied by

问题 I'm trying to do a nested join on a self referencing entity, please bear with me, it will make sense :) Thing.java class Thing { Integer something; Person owner; } Person.java class Person { String name; Person parent; } Note: A Person with parent=null means that they are a parent, and cannot have a parent. It's an alien world! :P Query: Root<Thing> root = query.from(Thing.class); Join<Thing, Person> ownerJoin = root.join(Thing_.owner); Join<Person, Person> parentJoin = ownerJoin.join(Person_

问题 I'm using spring-data-mongodb version 1.1.1.RELEASE . I am able to persist an object if all the member variables are primitive types, even if the names of the @PersistenceConstructor arguments don't match exactly the names of the member variables by using the @Field("foo") and @Value("#root.foo") annotations. However, I get a MappingInstantiationException (Illegal arguments for constructor) when I try to persist objects that contain primitive arrays. This holds true regardless of whether the
