1.通过java代码实现tomcat的关闭
2.tomcatstop.java
package test; import java.io.bufferedreader; import java.io.ioexception; import java.io.inputstreamreader; public class tomcatstop { public static void main(string[] args) { // todo auto-generated method stub system.out.println("访问已超出日访问量"); string command = "d:\\apache-tomcat-8.5.39\\bin\\shutdown.bat";// 关闭tomcat命令 try { callcommand(command); } catch (ioexception e) { system.out.println("执行命令时出错:" + e.getmessage()); } } public static void callcommand(string command) throws ioexception { runtime runtime = runtime.getruntime();// 返回与当前的java应用相关的运行时对象 // 指示java虚拟机创建一个子进程执行指定的可执行程序,并返回与该子进程对应的process对象实例 process process = runtime.exec(command); runtime.gc();// 运行垃圾回收器 string line = null; string content = ""; bufferedreader br = new bufferedreader(new inputstreamreader(process.getinputstream())); while ((line = br.readline()) != null) { content += line + "\r\n"; } system.out.println(content); } }
3.执行关闭命令
4.常见错误
执行代码后可能出现:
the catalina_home environment variable is not defined correctly
this environment variable is needed to run this program
此时需设置环境变量:
本人设置后运行依然报错,但是将电脑注销一下再次运行即可。
总结
