[FIXED] How add a new _link to an entity using spring data rest?

Issue

I want to add an extra link to a entity such as:

"_links": {
  "self": {
    "href": "http://localhost:8080/api/organizaciones"
  },
  "profile": {
    "href": "http://localhost:8080/api/profile/organizaciones"
  },
  "search": {
    "href": "http://localhost:8080/api/organizaciones/search"
  },
  "disable": {
    "href": "http://localhost:8080/api/organizaciones/disable"
  }
}

The idea behind this scenario is that I need to expose a soft delete via its own link within Organizacion entity... right now I'm only able to do:

http://localhost:8080/api/organizaciones/search/disable?id=100

in order to perform the soft delete. How can I achieve this the right way? Or is it my only alternative creating a controller?

Solution

You just need to add a class extending the ResourceProcessor interface and add it to the spring-context(http://docs.spring.io/spring-data/rest/docs/current/reference/html/#_the_resourceprocessor_interface) For example

@Bean
public ResourceProcessor<Resource<Person>> personProcessor() {

   return new ResourceProcessor<Resource<Person>>() {

     @Override
     public Resource<Person> process(Resource<Person> resource) {

      resource.add(new Link("http://localhost:8080/people", "added-link"));
      return resource;
     }
   };
}

Where the Person entity can be replaced with your Organizacion entity.
