jsp 调用linux shell

经常碰到运营部门人要清缓存，而缓存一直存在问题，老在电脑面前处理也不是个办法，想了个方法，通过访问一个jsp页面自动清缓存

<%@ page language="java" import="java.io.*" pageEncoding="UTF-8"%>

<%

String path = request.getContextPath();

String basePath = request.getScheme() + "://"

+ request.getServerName() + ":" + request.getServerPort()

+ path + "/";

%>

<%

String cmds = "monitor.sh";

try {

Process process;

process = Runtime.getRuntime().exec("sh /opt/test.sh");

InputStreamReader ir = new InputStreamReader(process

.getInputStream());

LineNumberReader input = new LineNumberReader(ir);

String line;

process.waitFor();

while ((line = input.readLine()) != null){

out.print(line);

out.print("
");

}

if(input!=null){

input.close();

}

} catch (Exception e) {

e.printStackTrace();

}

%>

 

test.sh 脚本内容

echo 'flush_all' | nc 192.168.10.73 11211

将该脚本放到jboss/server/default/deploy/jboss-web.deployer/ROOT.war/ 下就可以访问了
