springboot中如何运行linux命令呢?
下文笔者讲述SpringBoot中运行Linux命令的方法及示例分享,如下所示
使用Java中的Runtime类或ProcessBuilder类 即可运行Linux命令例:
使用Runtime类-运行Linux命令
@RestController
public class MyController {
@GetMapping("/execCommand")
public String execCommand() {
String command = "ls -l /tmp"; //待运行的Linux命令
try {
Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec(command);
BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
StringBuilder stringBuilder = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
stringBuilder.append(line);
stringBuilder.append(System.getProperty("line.separator"));
}
return stringBuilder.toString();
} catch (IOException e) {
e.printStackTrace();
return "Error";
}
}
}
使用ProcessBuilder类--运行linux命令
@RestController
public class MyController {
@GetMapping("/execCommand")
public String execCommand() {
String command = "ls -l /tmp"; //待运行的Linux命令
try {
ProcessBuilder processBuilder = new ProcessBuilder(command.split(" "));
Process process = processBuilder.start();
BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
StringBuilder stringBuilder = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
stringBuilder.append(line);
stringBuilder.append(System.getProperty("line.separator"));
}
return stringBuilder.toString();
} catch (IOException e) {
e.printStackTrace();
return "Error";
}
}
}
