[CI]Docker构建时传递CI的唯一生成号作为版本号（SpringBoot、Vue）

平台操作以AzureDevOps为例

CI配置

arguments: '--build-arg BUILD_NUMBER=$(Build.BuildNumber)'

前端

Dockerfile配置

# 动态更新 .env 文件
ARG BUILD_NUMBER
# 使用 sed 命令更新 .env 文件中的 VUE_APP_BUILD_NUMBER 变量
RUN sed -i "s/^VUE_APP_BUILD_NUMBER=.*/VUE_APP_BUILD_NUMBER=${BUILD_NUMBER}/" /app/.env

.env配置

VUE_APP_BUILD_NUMBER=unknown

代码

      <span style="margin-left: 8px;">
        服务版本：{{backend_version}}
        前端版本：{{front_version}}
      </span>

  data() {
      return {
        backend_version: "-",
        front_version:process.env.VUE_APP_BUILD_NUMBER
      }
  },
  mounted() {
    this.getDockerBuildId();
  },
  methods: {
    getDockerBuildId() {
      fetch('/api/sys/common/build')
          .then(response => response.json())
          .then(data => {
            this.backend_version = data.message;
          })
          .catch(error => {
            console.error('Error:', error);
          });
    }

后端

Dockerfile配置

# 定义构建参数
ARG BUILD_NUMBER
ENV BUILD_NUMBER=${BUILD_NUMBER}

# 使用传递的 BUILD_NUMBER 参数进行 Maven 构建
RUN mvn install -Dbuild.number=${BUILD_NUMBER}

pom.xml配置

    <properties>
        <build.number>0</build.number>
    </properties>

		  <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-jar-plugin</artifactId>
                <configuration>
                    <archive>
                        <manifestEntries>
                            <!-- 使用 build.number 参数作为版本号 -->
                            <Build-Version>${build.number}</Build-Version>
                        </manifestEntries>
                    </archive>
                </configuration>
            </plugin>

    @GetMapping("/build-id")

        String buildId = "unknown";
        try {
            // 加载 MANIFEST.MF 文件
            Resource resource = resourceLoader.getResource("classpath:META-INF/MANIFEST.MF");
            Manifest manifest = new Manifest(resource.getInputStream());
            Attributes attributes = manifest.getMainAttributes();

            // 获取 Build-Version 属性
            buildId = attributes.getValue("Build-Version");
            if (buildId == null) {
                buildId = "unknown";
            }
        } catch (IOException e) {
            // 处理异常
            e.printStackTrace();
        }

        return ResponseResult.info(Objects.equals(buildId, "unknown") ? 0 : 1, buildId, buildId);
    }
}
