Check HTTP Response Status for Success

All HTTP 2xx mean successful status codes.

So, it's fairly easy to check, but a bit harder to not duplicate those checks everywhere:) ##Code Samples: ###General universal way: if (statusCode < 200 || statusCode > 299) { // throws, redirects, server errors, lions and tigers and bears! } ###The simplest java way: if (statusCode / 100 != 2) { // throws, redirects, server errors, lions and tigers and bears! } *status codes are integers, so this expression will be an integer division.* ###No Magic Numbers way: if (Response.Status.fromStatusCode(statusCode).getFamily() != Response.Status.Family.SUCCESSFUL) { // throws, redirects, server errors, lions and tigers and bears! } ###No Magic Numbers Spring way: if (!HttpStatus.valueOf(statusCode).is2xxSuccessful()) { // throws, redirects, server errors, lions and tigers and bears! } ---- ## see Also * [All Http Status Codes](http://www.restapitutorial.com/httpstatuscodes.html) * [Spring 4 API - HttpStatus](https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/http/HttpStatus.html) * [Java EE 7 API - Response.Status](http://docs.oracle.com/javaee/7/api/javax/ws/rs/core/Response.Status.html) * [Apache Commons - HttpStatus](https://hc.apache.org/httpcomponents-core-ga/httpcore/apidocs/org/apache/http/HttpStatus.html) * [REST (Restful Web Services) ](http://bloomlab.blogspot.com.ee/2015/07/rest-restfull-webservices.html) * [Themeleaf - Offsite](http://www.thymeleaf.org/) * [Web Resource Optimizer for Java](http://alexo.github.io/wro4j/) * [Wro4j - Github](https://github.com/wro4j/wro4j) * [Keynote: Top JS frmeworks 2015](http://bloomlab.blogspot.com.ee/2015/03/top-javascript-frameworks-2015.html)
