String shell = OS.isFamilyUnix() ? "sh" : "cmd"; String shellArg = OS.isFamilyUnix() ? "-c" : "/c"; String command = "ps aux | grep java"; // 创建命令行对象,并设置shell及其参数 CommandLine cmdLine = new CommandLine(shell); cmdLine.addArgument(shellArg); cmdLine.addArgument(...
执行的命令被称为CommandLine,可使用该类的addArgument()方法为其添加参数,parse()方法将你提供的命令包装好一个可执行的命令。命令是由执行器Executor类来执行的,DefaultExecutor类的execute()方法执行命令,exitValue也可以通过该方法返回接收。设置ExecuteWatchdog可指定进程在出错后多长时间结束,这样有效防止了run-away...
在结束阶段,我们可以对Shell命令执行结果进行处理,比如打印结果或者进行进一步的处理。 3. 完整代码示例 下面是完整的Java代码示例: importjava.io.BufferedReader;importjava.io.IOException;importjava.io.InputStream;importjava.io.InputStreamReader;publicclassJavaExecuteShellCommand{publicstaticvoidmain(String[]args)...
publicclassShellScriptExample{publicstaticvoidmain(String[]args){try{CommandLinecommandLine=newCommandLine("sh");commandLine.addArgument("script.sh");DefaultExecutorexecutor=newDefaultExecutor();intexitValue=executor.execute(commandLine);System.out.println("Shell脚本执行结果:"+exitValue);}catch(IOException...
Java执行Shell命令的方式 一、使用Runtime执行Shell命令 Java的Runtime类提供了一个可以执行系统命令的方法,exec()方法可以执行任何系统命令,例子如下: 代码语言:javascript 代码运行次数:0 AI代码解释 try{Process process=Runtime.getRuntime().exec("ls /home");BufferedReader reader=newBufferedReader(newInput...
下面是一个使用Java执行Shell命令的示例代码: importjava.io.BufferedReader;importjava.io.IOException;importjava.io.InputStreamReader;publicclassShellCommandExecutor{publicstaticvoidmain(String[] args){try{ProcessBuilderprocessBuilder=newProcessBuilder("ls","-l");Processprocess=processBuilder.start(); ...
使用shell命令的java可以通过Java的Runtime类或ProcessBuilder类来实现。下面是一个简单的示例代码: 代码语言:txt 复制 import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; public class ShellCommandExample { public static void main(String[] args) { try { // 执行...
However, these applications would also prefer to use the same command line across multiple versions of the JDK, especially if it is not known what JDK version a user will use. Currently, if these options are specified in JDK 12 or earlier, the runtime attempts to load a SecurityManager ...
