POM配置

首先，我们可以挑选任意一个Spring Boot项目，修改它的pom.xml：

引入spring-boot-starter-actuator，提供/info端点

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

添加git-commit-id-plugin插件，该插件用来产生git的版本信息

<plugin>
    <groupId>pl.project13.maven</groupId>
    <artifactId>git-commit-id-plugin</artifactId>
    <version>2.1.15</version>
    <executions>
        <execution>
            <goals>
                <goal>revision</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <dotGitDirectory>${project.basedir}/.git</dotGitDirectory>
    </configuration>
</plugin>

#产生git版本信息

在完成了上面的配置之后，执行git-commit-id-plugin插件

运行完成后，我们可以在控台中看到类似下面的信息：

[INFO] pl.project13.maven.git.log.MavenLoggerBridge - dotGitDirectory E:\git_project\oschina\SpringBoot-Learning\.git
[INFO] pl.project13.maven.git.log.MavenLoggerBridge - git.build.user.name didi

[INFO] pl.project13.maven.git.log.MavenLoggerBridge - git.commit.id.abbrev e0540b3
[INFO] pl.project13.maven.git.log.MavenLoggerBridge - git.dirty true
...

同时，在target/classes目录下，我们可以发现产生了一个git.properties配置信息：

这个文件就是当前项目的git信息，它的内容如下：

#Generated by Git-Commit-Id-Plugin
#Thu Jun 01 17:57:53 CST 2017
git.build.user.email=dyc87112@qq.com
git.build.host=Lenovo-zhaiyc
git.dirty=true
git.remote.origin.url=https\://git.oschina.net/didispace/SpringBoot-Learning.git
git.closest.tag.name=chapter1
git.commit.id.describe-short=e0540b3-dirty
git.commit.user.email=dyc87112@qq.com
git.commit.time=2017-06-01T17\:57\:10+0800
git.commit.message.full=update
git.build.version=1.0.0
git.commit.message.short=update
git.commit.id.abbrev=e0540b3
git.branch=master
git.build.user.name=didi
git.closest.tag.commit.count=240
git.commit.id.describe=e0540b3-dirty
git.commit.id=e0540b3524378de9b5d938668a0f75ec016fa5e5
git.tags=
git.build.time=2017-06-01T17\:57\:53+0800
git.commit.user.name=didi

#启动测试

完成了上述配置之后，启动应用并访问端点，比如：curl localhost:8080/info，我们可以获得如下输出：

{
  "git": {
    "commit": {
      "time": 1496311030000,
      "id": "e0540b3"
    },
    "branch": "master"
  }
}

其中包含了关于branch和commit的基础信息。而这个信息格式是最简模式，我们也可以通过配置下面的参数来获取更全面的git信息：

management.info.git.mode=full

重启应用后再访问/info端点，可以获得类似下面更为详细的版本信息了。

{
  "git": {
    "build": {
      "host": "Lenovo-zhaiyc",
      "version": "1.0.0",
      "time": 1496311073000,
      "user": {
        "name": "didi",
        "email": "dyc87112@qq.com"
      }
    },
    "branch": "master",
    "commit": {
      "message": {
        "short": "update",
        "full": "update"
      },
      "id": "e0540b3524378de9b5d938668a0f75ec016fa5e5",
      "id.describe-short": "e0540b3-dirty",
      "id.abbrev": "e0540b3",
      "id.describe": "e0540b3-dirty",
      "time": 1496311030000,
      "user": {
        "email": "dyc87112@qq.com",
        "name": "didi"
      }
    },
    "closest": {
      "tag": {
        "name": "chapter1",
        "commit": {
          "count": "240"
        }
      }
    },
    "dirty": "true",
    "remote": {
      "origin": {
        "url": "https://git.oschina.net/didispace/SpringBoot-Learning.git"
      }
    },
    "tags": ""
  }
}
