Is Feign threadsafe...? <p>Is instance of Feign thread safe...? I couldn't find any documentation that supports this. Do anyone out there think otherwise?</p> <p>Here is the standard example posted on github repo for Feign...</p> <pre><code>interface GitHub { @RequestLine("GET /repos/{owner}/{repo}/contributors") List&lt;Contributor&gt; contributors(@Param("owner") String owner, @Param("repo") String repo); } static class Contributor { String login; int contributions; } public static void main(String... args) { GitHub github = Feign.builder() .decoder(new GsonDecoder()) .target(GitHub.class, "https://api.github.com"); // Fetch and print a list of the contributors to this library. List&lt;Contributor&gt; contributors = github.contributors("netflix", "feign"); for (Contributor contributor : contributors) { System.out.println(contributor.login + " (" + contributor.contributions + ")"); } } </code></pre> <p>Should I change this to following... Is it thread safe...?</p> <pre><code>interface GitHub { @RequestLine("GET /repos/{owner}/{repo}/contributors") List&lt;Contributor&gt; contributors(@Param("owner") String owner, @Param("repo") String repo); } static class Contributor { String login; int contributions; } @Component public class GithubService { GitHub github = null; @PostConstruct public void postConstruct() { github = Feign.builder() .decoder(new GsonDecoder()) .target(GitHub.class, "https://api.github.com"); } public void callMeForEveryRequest() { github.contributors... // Is this thread-safe...? } } </code></pre> <p>For the example above... I've used spring based components to highlight a singleton. Thanks in advance...</p>
