spring-data-rest

问题 I'm using Spring Data REST to expose my Entity's and their relationships. I have a OneToOne relationship between two Entity's and I'm trying to update/change the relationship with PUT and PATCH. I noticed that Spring Data REST will only allow you to update linked resources - JPA mapped Entity's (OneToMany, ManyToOne, etc) which are also AggregateRoots (has a Repository) - via a PATCH and are ignored with a PUT . This can be seen in the LinkedAssociationSkippingAssociationHandler class: if

问题 I am working on the spring data rest services & facing some issue in the custom interceptors.

But when i upgraded to spring-data-rest-webmvc 2.3

问题 I am using Jackson's Hibernate4Module to deal with the serialization issues when dealing with a lazily loaded proxy in a Spring Data Rest project. In general it solves the issue of Jackson trying to serialise uninitialized proxies however one side effect is that the JSON output differs: Fetched directly: api/cases/5400 { "id": 5400, "practiceReference": "DWPYI9" } Fetched via a lazily loaded @ManyToOne: api/submissions/11901/parentCase { "content": { "id": 5400, "practiceReference": "DWPYI9"

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 I want to create a REST link for an Employee entity that will basically be a findByAllFields query. Of course this should be combined with Page and Sort . In order to do that I have implemented the following code: @Entity public class Employee extends Persistable<Long> { @Column private String firstName; @Column private String lastName; @Column private String age; @Column @Temporal(TemporalType.TIMESTAMP) private Date hiringDate; } So I would like to have lets say a query where I can do: http

问题 I have a MongoRepository of @RepositoryRestResource(collectionResourceRel = "tools") public interface ToolRepository extends MongoRepository<Tool, Long> Tool can be one of 2 implementations: public class Screwdriver extends Tool public class Hammer extends Tool Tool is mapped using @JsonTypeInfo @JsonTypeInfo(use = com.fasterxml.jackson.annotation.JsonTypeInfo.Id.CLASS, include = As.PROPERTY, property = "_class") public abstract class Tool When I do toolRepository.findAll() this returns a

问题 There are following URLS - /users/2/profile , /users/2/userPosts I need to concat output of both Spring Data REST results in server side and build single JSON from them and send on different URL /users/2/custom . So, I am thinking to make 2 calls to SDR urls from Spring MVC, can we do this using RestTemplate and some JSON concat utility , here server and database is on same machine so RestTemplate will probably have localhost An example will help 回答1: You might rather want to look into the
