需求

需求描述：需要加入版本控制，所以需要获取本次提交 git 的commit id

方案

1、配置文件中写静态的哈希值，每次发布都修改。
优势：开发周期短。
劣势：会死在上边。。。。。

2、动态获取git提交的commit id，会在编译的时候在classes下生成一个git.properties，在前端访问的时候直接读取配置文件。
优势：大大减少错误的概率。（默认但凡需要人每次操作的部分都会存在错误的可能性）

技术实现

需要先集成一个工具 [git-commit-id-plugin]

            <plugin>
                <groupId>pl.project13.maven</groupId>
                <artifactId>git-commit-id-plugin</artifactId>
                <version>2.2.4</version>
                <executions>
                    <execution>
                        <id>get-the-git-infos</id>
                        <goals>
                            <goal>revision</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <dotGitDirectory>$project.basedir/.git</dotGitDirectory>
                    <prefix>git</prefix>
                    <verbose>true</verbose>
                    <dateFormat>yyyy-MM-dd'T'HH:mm:ssZ</dateFormat>
                    <!-- 是否生 git.properties 属性文件 -->
                    <generateGitPropertiesFile>true</generateGitPropertiesFile>
                    <!-- 生成版本信息文件名 -->
                    <generateGitPropertiesFilename>$project.build.outputDirectory/git.properties</generateGitPropertiesFilename>
                    <format>json</format>
                    <!-- git描述配置,可选;由JGit提供实现 -->
                    <gitDescribe>
                        <!-- 是否生成描述属性 -->
                        <skip>false</skip>
                        <!-- 提交操作未发现tag时,仅打印提交操作ID -->
                        <always>false</always>
                        <!-- 提交操作ID显式字符长度,最大值为:40;默认值:7; 0代表特殊意义;后面有解释; -->
                        <abbrev>7</abbrev>
                        <!-- 构建触发时,代码有修改时(即"dirty state"),添加指定后缀;默认值:""; -->
                        <dirty>-dirty</dirty>
                    </gitDescribe>
                </configuration>
            </plugin>

实现类

package com.yunhuxi.jwgateway.service.version.impl;

import com.alibaba.fastjson.JSONObject;
import com.yunhuxi.jwgateway.service.version.VersionService;
import org.springframework.stereotype.Service;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.nio.charset.StandardCharsets;

/**

 */
@Service
public class VersionServiceImpl implements VersionService 

    @Override
    public String getCommitId() 
        ClassLoader classLoader = getClass().getClassLoader();
        InputStream inputStream = classLoader.getResourceAsStream("git.properties");
        try 
            String gitProperties = readFromInputStream(inputStream);
            JSONObject jsonObject = JSONObject.parseObject(gitProperties);
            String commitId = (String) jsonObject.get("git.commit.id.abbrev");
            return commitId;
         catch (IOException e) 
            e.printStackTrace();
            return "Version information could not be retrieved.";
        
    

    private String readFromInputStream(InputStream inputStream)
            throws IOException 
        StringBuilder result = new StringBuilder();
        try (
                BufferedReader br = new BufferedReader(new InputStreamReader(inputStream, StandardCharsets.UTF_8.name()))
        ) 
            String line;
            while ((line = br.readLine()) != null) 
                result.append(line).append(System.lineSeparator());
            
        
        return result.toString();
