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.

server.info=Apache Tomcat/6.0.32
server.number=6.0.32.0
server.built=February 2 2011 2003

 

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"));                        
    }
