Java代码运作可执行文件

Java代码运行可执行文件

先写个例子，用Java启动tomcat

package com.yymt.pf.rpc.loadbalance;import java.io.File;import java.io.IOException;public class ExecFileUtil {public static void main(String[] args) throws IOException {run("cmd /C start startup.bat", null, new File("E:\\develop_tools\\apache-tomcat-6.0.26\\bin\"));System.out.println("Started!");}/** * @param path *            a specified system command * @param envp *            array of strings, each element of which has environment *            variable settings in the format name=value, or null if the *            subprocess should inherit the environment of the current *            process. * @param dir *            the working directory of the subprocess, or null if the *            subprocess should inherit the working directory of the current *            process. * @return * @throws IOException */public static Process run(String cmd, String[] envp, File dir)throws IOException {Runtime rt = Runtime.getRuntime();return rt.exec(cmd, envp, dir);}}

?其实很简单，但是结合一些应用场景，也许就很有用了，比如在软件级集群，集群控制器可以通过批处理命令来重启健康状况恶化的服务器实例。当然是指单机多实例集群，跨物理机的集群，应该需要os或者硬件级别的支持吧
