How to disable RepositoryRestHandlerMapping and EndpointHandlerMapping?

阅读更多关于 How to disable RepositoryRestHandlerMapping and EndpointHandlerMapping?

问题 I am currently building an application with a REST interface, using Spring Boot, Hibernate and Spring-HATEOAS. My data model is defined as beans with @Entity annotation and I am using Spring's feature to automatically set up a Hibernate repository (Creating an interface extending PagingAndSortingRepository ). My application is completely annotation-driven, i.e., I have no web.xml but configure everything with the Spring annotations like @Configuration , @Bean etc., and start the application

Spring Data REST - Consume List of Entities, Java HATEOAS client

阅读更多关于 Spring Data REST - Consume List of Entities, Java HATEOAS client

I'm using Spring Data REST 2.5.1, Jackson 2.8.0, Spring Boot 1.3.6. I'm trying to retrieve a simple list of entities from my Repository via RestTemplate. I can hit the end point in a browser, and get the expected HAL data. Retrieving a single Entity works fine as below. These are all using the default SDR endpoints (e.g. localhost:{port}/myEntity). ResponseEntity<Resource<MyEntity>> responseEntity = new RestTemplate() .exchange( uri + "/1", HttpMethod.GET, HttpEntity.EMPTY, new ParameterizedTypeReference<Resource<MyEntity>>() {}, port ) Or new RestTemplate().getForEntity(uri + "/1", MyEntity

Resolving entity URI in custom controller (Spring HATEOAS)

阅读更多关于 Resolving entity URI in custom controller (Spring HATEOAS)

I have a project based on spring-data-rest and also it has some custom endpoints. For sending POST data I'm using json like { "action": "REMOVE", "customer": "http://localhost:8080/api/rest/customers/7" } That is fine for spring-data-rest, but does not work with a custom controller. for example: public class Action { public ActionType action; public Customer customer; } @RestController public class ActionController(){ @Autowired private ActionService actionService; @RestController public class ActionController { @Autowired private ActionService actionService; @RequestMapping(value = "/customer

HATEOAS paths are invalid when using an API Gateway in a Spring Boot app

阅读更多关于 HATEOAS paths are invalid when using an API Gateway in a Spring Boot app

I have two spring boot applications where one of them is acting as an API Gateway (as discussed here Spring Example ). The other which is wired into the first one is exposing a profile service using spring-data-rest (spring-data-neo4j-rest). The first application is starting on port 8080 and is using zuul to route requests to the second as follows: zuul: routes: profiles: path: /profiles/** url: http://localhost:8083/profiles/ This all works fine and requests to http://localhost:8080/profiles are being served from the second app. The problem though is that the HATEOAS links in the response are

问题 I'm using Spring Boot and HATEOAS to build a REST API and when my API returns a collection, it is wrapped inside a "_embedded" property, like so: { "_links":{ "self":{ "href":"http://localhost:8080/technologies" } }, "_embedded":{ "technologies":[ { "id":1, "description":"A", "_links":{ "self":{ "href":"http://localhost:8080/technologies/1" } } }, { "id":2, "description":"B", "_links":{ "self":{ "href":"http://localhost:8080/technologies/2" } } } ] } } I want the response to be like this: { "

How to change HAL links format using Spring HATEOAS

阅读更多关于 How to change HAL links format using Spring HATEOAS

I'm building a Spring REST application using Spring HATEOAS (0.16.0.RELEASE) and I'd like the JSON links output to look like: _links: { self: { href: "https://<ip>/api/policies/321" } } while it renders like: "links": [{ "rel":"self", "href":"http://<ip>/api/policies/321" }] I'm using HATEOAS Resource and ResourceAssembler . Why do I get this format instead of the other? How can I change it? In order to use HAL as the message format language for our RESTful API, and enable automatic pagination, we need some configuration changes in our applicaiton. Since Spring Data and Spring HATEOAS already

How do I avoid n+1 queries with Spring Data Rest?

阅读更多关于 How do I avoid n+1 queries with Spring Data Rest?

问题 Question. How do I avoid n+1 queries with Spring Data REST? Background. When querying Spring Data REST for a list of resources, each of the resulting top-level resources has links to the associated resources, as opposed to having the associated resources embedded directly in the top-level resources. For example, if I query for a list of data centers, the associated regions appear as links, like this: { "links" : [ { "rel" : "self", "href" : "http://localhost:2112/api/datacenters/1" }, { "rel"

Spring Rest: Cannot insert rows that have @ManyToOne column

阅读更多关于 Spring Rest: Cannot insert rows that have @ManyToOne column

问题 I am following a spring getting started tutorial in https://spring.io/guides/gs/accessing-data-rest/ I added another entity books that has @ManyToOne relation to Person entity.
