Spring Boot 获取maven打包时间

1. 引入maven打包插件

   <build>
       <plugins>
           <!-- 打包时生成打包时间 -->
           <plugin>
               <groupId>org.codehaus.mojo</groupId>
               <artifactId>buildnumber-maven-plugin</artifactId>
               <version>3.2.0</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>
   
       <!-- maven打包时包含静态资源文件 -->
       <resources>
   
           <resource>
               <directory>src/main/resources</directory>
               <includes>
                   <include>**/*.properties</include>
                   <include>**/*.yaml</include>
                   <include>META-INF/**</include>
                   <include>**/*.xml</include>
               </includes>
               <!-- true表示maven会对文件进行过滤，将@project.version@替换为该属性的值 -->
               <filtering>true</filtering>
           </resource>
   
           <resource>
               <directory>src/main/java</directory>
               <includes>
                   <include>**/*.properties</include>
                   <include>**/*.xml</include>
               </includes>
               <filtering>true</filtering>
           </resource>
   
       </resources>
   </build>

   2. application.properties内引用

   #获取build时的时间
   app.buildTime=@timestamp@
   #获取项目版本
