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

这里有些参考
