title: Spring-Data-JPA method save(Iterable<S>) is not applicable for the arguments (Book)
body: <p>I am using spring-data-jpa 1.3.2.RELEASE. I was trying to save a Book object in my service. I am getting the following error: The method save(Iterable) in the type JpaRepository is not applicable for the arguments (Book). My method looks like this. </p>
  
  <pre><code>@Autowired 
  private BookRepository bookRepository;
  
  public Book save(Book book){
   return bookRepository.save(book);
  }
  </code></pre>
  
  <p>Updated</p>
  
  <pre><code>public interface BookRepository extends JpaRepository&lt;Book, Long&gt; {
     public Book save(Book book);
  }
  </code></pre>
