5.23. Spring boot with Git version

Spring boot 每次升级打包发给运维操作，常常运维操作不当致使升级失败，开发怎样确认线上的jar/war包与升级包一致呢？

请看下面的解决方案

5.23.1. CommonRestController 公共控制器

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());
	}
}

5.23.2. VersionRestController 测试控制器

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.";
	}

}

5.23.3. 创建 .gitattributes 文件

			# 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
