如何在运行Tomcat时获取软件包版本？

解决方法：
1）使用

mvn war:manifest

version  = getClass().getPackage().getImplementationVersion();  if (version==null) {    Properties prop = new Properties();    try {        prop.load(getServletContext().getResourceAsStream("/meta-INF/MANIFEST.MF"));        version = prop.getProperty("Implementation-Version");    } catch (IOException e) {        logger.error(e.toString());    }}logger.info("Starting App version "+version);
