场景:
Spring Boot 打 jar 包时,文件命名增加编译时间;以及在 application.yml
配置文件中拿到编译时间;
Apache Maven 3.8.2
Spring Boot 2.4.1
一、maven.build.timestamp
1、pom.XML
<properties> <buildTime>${maven.build.timestamp}</buildTime> <maven.build.timestamp.format>yyyy-MM-dd HH:mm:ss</maven.build.timestamp.format> </properties>
2、application.yml
app: version: @project.version@ buildTime: @buildTime@
要在 application.yml
配置中获取到 pom.xml
中的属性,需要添加如下配置
<build> <!-- jar 包命名格式 --> <finalName>${project.artifactId}-${version}-${buildTime}</finalName> <resources> <resource> <directory>src/main/resources</directory> <filtering>true</filtering> <js;/resource> </resources> </build>
不过这种方式获取到的时间有时区问题,拿到的是 UTC 时间,无法指定时区,因此比中国晚 8 小时;为解决时区问题,可使用插件 buildnumber-maven-plugin
或 build-helper-maven-plugin
获取编译时间
二、buildnumber-maven-plugin
1、pom.xml
<build> <finalName>${project.artifactId}-${version}-${timestamp}</finalName> <plugins> <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>buildnumber-maven-plugin</artifactId> <version>3.0.0</version> <configuration> <timestampFormat>yyyy-MM-dd HH:mm:ss</timestampFormat> </configuration> <executions> <execution> <goals> <goal>create-timestamp</goal> </goals> </execution> </executions> <inherited>false</inherited> </plugin> </plugins> <resources> <resource> <directory>src/main/resources</directory> <filtering>true</filtering> </resource> </resources> </build>
2、application.yml
app: version: @project.version@ buildTime: @timestamp@
三、build-helper-maven-plugin
1、pom.xml
<build> <finalName>${project.artifactId}-${version}-${buildTime}</finalName> <plugins> <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>build-helper-maven-plugin</artifactId> <version>3.2.0</version> <executions> <execution> <id>timestamp-property</id> <goals> <goal>timestamp-property</goal> </goals> <configuration> <name>buildTime</name> <pattern>yyyyMMddHHmmss</pattern> <locale>zh_CN</locale> <timeZone>GMT+8</timeZone> </configuration> </execution> </executions> </plugin> </plugins> <resources> <resource> <directory>src/main/resources</directory> <filtering>true</filtering> </resource> </resources> </build>
2、application.yml
app: version: @project.version@ buildTime: @buildTime@
⚠️注意:finalName
标签配置的 jar 包名称格式中,如果存在冒号:
时,虽然可以在 IDEA 中点击 Run
按钮启动,但是部署时使用 Java -jar ***.jar
无法启动并报错:
找不到或无法加载主类 org.springframework.boot.loader.JarLauncher
上面三种方式通过 maven 打包之后在运行,都可以在 yml 配置中获取到编译的时间值;但是如果没打包,直接点击 Run
按钮启动 Spring Boot 程序;maven.build.timestamp
可以正常获取到时间,buildnumber-maven-plugin
的 timestamp 为空;而 build-helper-maven-plugin
直接报错:
17:55:22.077 [main] ERROR org.springframework.boot.SpringApplication - Application run failed
org.yaml.snakeyaml.scanner.ScannerException: whilandroide scanning for the next tokenfound character &android#39;@' that cannot start any token. (Do not use @ for indentation) in 'reader', line 23, column 14: buildTime: @bwww.devze.comuildTime@ ^
