Springboot中获取git提交信息，通过springboot actuator的/info endpoint查看

《Springboot中获取git提交信息，通过springboot actuator的/info endpoint查看》

项目中的代码放git上管理，jenkins的CICD的流水线打包发布下，经常容易忘记提交代码或者合并分支等。导致调试时和预期不一致，如果把代码的git提交记录在运行时展示出来，就可以快速确认是否是环境部署的问题导致的。

build.gradle中增加

plugins {
    id "com.gorylenko.gradle-git-properties" version "1.5.1"
}

java代码：

@Slf4j
@Component
public class GitCommitInfoApplicationRunner implements ApplicationRunner {

    @Value("${spring.application.name:}")
    private String applicaitonName;

    @Override
    public void run(ApplicationArguments args) throws Exception {
        try {
            Resource resource = new ClassPathResource("git.properties");
            Properties properties = new Properties();
            properties.load(new InputStreamReader(resource.getInputStream()));
            log.info("{}打包日志: 分支[{}],代码版本[{}],构建时间[{}],提交时间[{}]", applicaitonName,
                    properties.getProperty("git.closest.tag.name"),
                    properties.getProperty("git.commit.id.abbrev"),
                    properties.getProperty("git.build.time"),
                    properties.getProperty("git.commit.time"));
            log.info("{}-GitCommitInfo: [{}]", applicaitonName, properties);
        } catch (FileNotFoundException e) {
            log.warn("git.properties文件不存在");
        } catch (IOException e) {
            log.warn("git.properties文件读取失败");
        }
    }
}

二、/info的endpoint如何读取git信息的呢？

重写：

public class GitInfoContributor extends InfoPropertiesInfoContributor<GitProperties> {

    public GitInfoContributor(GitProperties properties, Mode mode) {
        super(properties, mode);
    }

    public GitInfoContributor(GitProperties properties) {
        this(properties, Mode.SIMPLE);
    }

    @Override
    public void contribute(Info.Builder builder) {
        builder.withDetail("git", generateContent());
    }

    @Override
    protected PropertySource<?> toSimplePropertySource() {
        Properties props = new Properties();
        copyIfSet(props, "branch");
        String commitId = getProperties().getShortCommitId();
        if (commitId != null) {
            props.put("commit.id", commitId);
        }
        copyIfSet(props, "build.time");
        copyIfSet(props, "build.user.email");
        copyIfSet(props, "build.version");
        copyIfSet(props, "closest.tag.name");
        copyIfSet(props, "commit.id.abbrev");
        copyIfSet(props, "commit.id.describe");
        copyIfSet(props, "commit.message.full");
        copyIfSet(props, "commit.message.short");
        copyIfSet(props, "commit.user.email");
        copyIfSet(props, "commit.time");
        copyIfSet(props, "remote.origin.url");

        return new PropertiesPropertySource("git", props);
    }
