title: Feign - URL encode path params
body: <p>This is my contract,</p>
  
  <pre><code>@RequestLine("GET /products/{id}")
  @Headers({"Content-Type: application/json"})
  ApiResponse getProduct(@Param("id") String productId) throws Exception;
  </code></pre>
  
  <p>I want to fetch the product with id = "a/b",</p>
  
  <p>If I send this as a param to <code>getProduct("a/b")</code></p>
  
  <p>then the URL that is formed is <code>http://api/products/a/b</code> and I am getting a 404 instead the url should be <code>http://api/products/a%2Fb</code></p>
  
  <p>Is there a way around this?</p>
