title: How to expose @EmbeddedId converters in Spring Data REST
body: <p>There are some Entities with composite Primary Keys and these entities when exposed are having incorrect Links having full qualified name of classes in URL inside _links</p>
  
  <p>Also clicking on links gives such errors -</p>
  
  <pre><code>org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type java.lang.String to type com.core.connection.domains.UserFriendshipId
  </code></pre>
  
  <p>I have XML configured Spring Repository with jpa:repositories enabled and Respository extending from JpaRepository</p>
  
  <p>Can I make Repository implement <strong>org.springframework.core.convert.converter.Converter</strong> to handle this. Currently getting links as below -</p>
  
  <pre><code>_links: {
  userByFriendshipId: {
  href: "http://localhost:8080/api/userFriendships/com.core.connection.domains.UserFriendshipId@5b10/userByFriendId"
  }
  </code></pre>
  
  <p>in xml config , I have jpa:repositories enabled and @RestResource enabled inside Repositories</p>
