POM配置

首先，我們可以挑選任意一個Spring Boot項目，修改它的pom.xml：

• 引入spring-boot-starter-actuator，提供/info端點

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

• 添加git-commit-id-plugin插件，該插件用來產生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>

#產生git版本信息

• 在完成了上面的配置之后，執行git-commit-id-plugin插件

運行完成后，我們可以在控臺中看到類似下面的信息：

[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.build.user.email dyc87112@qq.com

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

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

同時，在target/classes目錄下，我們可以發現產生了一個git.properties配置信息：

這個文件就是當前項目的git信息，它的內容如下：

#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

#啟動測試

完成了上述配置之后，啟動應用并訪問端點，比如：curl localhost:8080/info，我們可以獲得如下輸出：

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

其中包含了關于branch和commit的基礎信息。而這個信息格式是最簡模式，我們也可以通過配置下面的參數來獲取更全面的git信息：

management.info.git.mode=full

重啟應用后再訪問/info端點，可以獲得類似下面更為詳細的版本信息了。

{
  "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": ""
  }
}
