所有 RestController将会集成 CommonRestController

package cn.netkiller.api.rest;import org.springframework.http.HttpStatus;
import org.springframework.security.core.annotation.AuthenticationPrincipal;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseStatus;public class CommonRestController {@RequestMapping("ping")@ResponseStatus(HttpStatus.OK)public String welcome() {return "PONG";}@RequestMapping("commit")public String commit() {return "$Id$";}@RequestMapping("auth")@ResponseStatus(HttpStatus.OK)public String auth(@AuthenticationPrincipal final UserDetails user) {return String.format("%s: %s %s", user.getUsername(), user.getPassword(), user.getAuthorities());}
}

我们创建一个RestController并继承CommonRestController用来测试

package cn.netkiller.api.rest;@RestController
@RequestMapping("/public/version")
public class VersionRestController extends CommonRestController {private static final Logger logger = LoggerFactory.getLogger(VersionRestController.class);public VersionRestController() {// TODO Auto-generated constructor stub}@RequestMapping("welcome")@ResponseStatus(HttpStatus.OK)public String welcome() {return "Welcome to RestTemplate version 1.0.";}}

# vim .gitattributes
src/main/java/cn/netkiller/api/rest/CommonRestController.java ident

使用curl命令调用commit接口可以显示当前war/jar最后一次提交的版本号码（你同样可以使用IE浏览器）

curl https://api.netkiller.cn/public/version/commit.json
