Enable HAL serialization in Spring Boot for custom controller method

阅读更多关于 Enable HAL serialization in Spring Boot for custom controller method

I'm trying to build a RESTful API with Spring Boot using spring-boot-starter-data-rest. There are some entities: accounts, transactions, categories and users - just the usual stuff. When I retrieve the objects at http://localhost:8080/transactions via the API that has been generated by default, all is going well an I get a list with all transactions as JSON objects like that one: { "amount": -4.81, "date": "2014-06-17T21:18:00.000+0000", "description": "Pizza", "_links": { "self": { "href": "http://localhost:8080/transactions/5" }, "category": { "href": "http://localhost:8080/transactions/5

阅读更多关于 While using Spring Data Rest after migrating an app to Spring Boot, I have observed that entity properties with @Id are no longer marshalled to JSON

This question is related to this SO question ( Spring boot @ResponseBody doesn't serialize entity id ). I have observed that after migrating an app to Spring Boot and using the spring-boot-starter-data-rest dependency, my entity @Id fields are no longer marshalled in the resulting JSON. This is my request mapping and while debugging, I can see the data isn't being changed prior to returning it, so the @Id properties are being stripped later on. @RequestMapping(method = RequestMethod.GET, produces = {"application/json"}) public PagedResources<Receipt> receipts(Pageable pageable,

How to configure Spring HATEOAS behind proxy?

阅读更多关于 How to configure Spring HATEOAS behind proxy?

问题 I have Spring Data Rest with Hateoas as my backed. It is behind a proxy. Backend url: backend.com Proxy url: proxy.com When I query proxy url, e.g. http://proxy.com/items/1 , I get a response with href links with domain backend.com . I need the domain to be proxy.com . 回答1: As of Spring-Boot 2.1 / Spring 5.1, Spring shifts the responsibility of handling X-Forwarded-* from Spring HATEOAS to Spring MVC. https://jira.spring.io/browse/SPR-16668 You now require the registration of a filter bean.

Custom jpa repository method published by spring-data-rest

阅读更多关于 Custom jpa repository method published by spring-data-rest

问题 I've added a custom method to a jpa repository as detailed on http://docs.spring.io/spring-data/data-jpa/docs/1.0.x/reference/html/#repositories.custom-implementations As far as I could see, this method is not exposed when I use spring-data-rest. Is there any way I could publish it as part of the REST API generated by spring-data-rest (without creating a Spring MVC Controller myself)? 回答1: I checked the code base - seems like they have explicitily disabled custom methods - not sure why.

Multiple Repositories for the Same Entity in Spring Data Rest

阅读更多关于 Multiple Repositories for the Same Entity in Spring Data Rest

问题 Is it possible to publish two different repositories for the same JPA entity with Spring Data Rest? I gave the two repositories different paths and rel-names, but only one of the two is available as REST endpoint. The point why I'm having two repositories is, that one of them is an excerpt, showing only the basic fields of an entity. 回答1: The terrible part is not only that you can only have 1 spring data rest repository (@RepositoryRestResource) per Entity but also that if you have a regular

Spring Data REST: Override repository method on the controller

阅读更多关于 Spring Data REST: Override repository method on the controller

问题 I have the following REST repository, whose implementation is generated at runtime by Spring. @RepositoryRestResource public interface FooRepository extends CrudRepository<Foo, Long> { } This means that I will have save(), find(), exists() and other methods available and exposed via REST. Now, I would like to override one of the methods; for example, save(). For that, I would create a controller exposing that method, like so: @RepositoryRestController @RequestMapping("/foo") public class

How to use Spring managed Hibernate interceptors in Spring Boot?

阅读更多关于 How to use Spring managed Hibernate interceptors in Spring Boot?

Is it possible to integrate Spring managed Hibernate interceptors ( http://docs.jboss.org/hibernate/orm/4.3/manual/en-US/html/ch14.html ) in Spring Boot? I'm using Spring Data JPA and Spring Data REST and need an Hibernate interceptor to act on an update of a particular field on an entity. With standard JPA events it's not possible to get the old values, and hence I think I need to use the Hibernate interceptor. Phil Webb There's not a particularly easy way to add a Hibernate interceptor that is also a Spring Bean but you can easily add an interceptor if it's manged entirely by Hibernate. To
