查看tomcat服务器信息
环境变量CATALINA_HOME: tomcat的安装目录.显示tomcat服务器信息的方式很多,
1. 运行%CATALINA_HOME%\bin目录下的version.bat批处理文件
2. 在命令行输入命令: "%CATALINA_HOME%\bin\catalina.bat" version
这些事实上都是调用%CATALINA_HOME%\lib\catalina.jar类库中org\apacha\catalina\util\ServerInfo.properties配置信息.
修改org\apacha\catalina\util\ServerInfo.properties中的配置信息后,上面二种方式显示的结果会相应地发生变化.

可以通过运行catalina.jar中org.apache.catalina.util.ServerInfo输出tomcat服务器信息
相关命令:java -cp "%CATALINA_HOME%\lib\catalina.jar" org.apache.catalina.util.ServerInfo
org.apache.catalina.util.ServerInfo关键代码:
static { try { InputStream is = ServerInfo.class.getResourceAsStream ("/org/apache/catalina/util/ServerInfo.properties"); Properties props = new Properties(); props.load(is); is.close(); serverInfo = props.getProperty("server.info"); serverBuilt = props.getProperty("server.built"); serverNumber = props.getProperty("server.number"); } catch (Throwable t) { ; } if (serverInfo == null) serverInfo = "Apache Tomcat"; if (serverBuilt == null) serverBuilt = "unknown"; if (serverNumber == null) serverNumber = "5.5.0.0"; }public static void main(String args[]) { System.out.println("Server version: " + getServerInfo()); System.out.println("Server built: " + getServerBuilt()); System.out.println("Server number:" + getServerNumber()); System.out.println("OS Name: " + System.getProperty("os.name")); System.out.println("OS Version: " + System.getProperty("os.version")); System.out.println("Architecture: " + System.getProperty("os.arch")); System.out.println("JVM Version: " + System.getProperty("java.runtime.version")); System.out.println("JVM Vendor: " + System.getProperty("java.vm.vendor")); }
