使用java向linux服务器端发送信号

String signalStr;
signalStr = "kill -" +  “-9” + " " + “pid”;
Runtime run = Runtime.getRuntime(); // 返回与当前 Java 应用程序相关的运行时对象
try {
Process p = run.exec(signalStr); // 启动另一个进程来执行命令
BufferedInputStream in = new BufferedInputStream(p.getInputStream());
BufferedReader inBr = new BufferedReader(new InputStreamReader(in));
String lineStr;
while ((lineStr = inBr.readLine()) != null) {
// 获得命令执行后在控制台的输出信息
System.out.println(lineStr);
}
// 检查命令是否执行失败。
if (p.waitFor() != 0) {
if (p.exitValue() == 1) {
System.err.println("命令执行失败!");
}
}
inBr.close();
in.close();
} catch (Exception e) {
e.printStackTrace();
}
