ProcessBuilder ProcessBuilder java.lang.Exception：
提问于 2014-03-25 19:57:44
我试图弄清楚为什么下面的代码会抛出一个
java.lang.Exception:没有这样的文件或目录
异常
ProcessBuilder send = new ProcessBuilder("/bin/bash","/opt/ftp/scripts/XFER.sh | /opt/ftp/myftp -c /opt/ftp/ftp.conf >> /logging/ftp.log2>&1");
Process sendProcess = send.start();
br = new BufferedReader(new InputStreamReader(sendProcess.getErrorStream()));
builder = new StringBuilder();
line = null;
while ( (line = br.readLine()) != null) {
builder.append(line);
builder.append(System.getProperty("line.separator"));
}
if(!builder.toString().isEmpty()){
throw new Exception( "ERROR with XFER.sh: "+builder.toString() );
} 我尝试过在String中隔离参数，但这也不起作用。有什么想法可以导致这种叠置吗？

我成功地使用了以下代码。也许您必须使用-c选项：
private static int execute(String command) {
Runtime runtime = null;
Process process = null;
int exitValue = -1;
BufferedInputStream bis = null;
try {
runtime = Runtime.getRuntime();
process = runtime.exec(new String[] { "/bin/bash", "-c", command });
bis = new BufferedInputStream(process.getInputStream());
byte[] b = new byte[1892];
while (bis.read(b) != -1) {
}
exitValue = process.waitFor();
if (bis != null) {
try {
bis.close();
} catch (IOException e) {
}
}
if (process != null) {
process.destroy();
}
} catch (Exception e) {
//Logging
}
return exitValue;
