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...
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(...
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...
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) { ...
最近项目中需要用到java语言来执行shell命令,在网上查了资料, 把自己在项目里用到的命令整理成了工具类开放给大家,希望对大家有用。功能不全,后期我会慢慢添加整合。 publicclassShellUtils {publicstaticfinal String COMMAND_SU ="su";publicstaticfinal String COMMAND_SH ="sh";publicstaticfinal String COMMAND_...
在Java中运行shell命令可以使用`Runtime`类或`ProcessBuilder`类来实现。这两种方法都可以在特定目录中执行shell命令。 1. 使用`Runtime`类: - 概...
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 ...
