【问题描述】:
我正在开发一个应用程序,但在从 java 应用程序运行 shell 命令时遇到问题。这是代码:
public String execRuntime(String cmd) {
Process proc = null;
int inBuffer, errBuffer;
int result = 0;
StringBuffer outputReport = new StringBuffer();
StringBuffer errorBuffer = new StringBuffer();
try {
proc = Runtime.getRuntime().exec(cmd);
} catch (IOException e) {
return "";
}
try {
response.status = 1;
result = proc.waitFor();
} catch (InterruptedException e) {
return "";
}
if (proc != null && null != proc.getInputStream()) {
InputStream is = proc.getInputStream();
InputStream es = proc.getErrorStream();
OutputStream os = proc.getOutputStream();
try {
while ((inBuffer = is.read()) != -1) {
outputReport.append((char) inBuffer);
}
while ((errBuffer = es.read()) != -1) {
errorBuffer.append((char) errBuffer);
}
} catch (IOException e) {
return "";
}
try {
is.close();
is = null;
es.close();
es = null;
os.close();
os = null;
} catch (IOException e) {
return "";
}
proc.destroy();
proc = null;
}
if (errorBuffer.length() > 0) {
logger
.error("could not finish execution because of error(s).");
logger.error("*** Error : " + errorBuffer.toString());
return "";
}
return outputReport.toString();
}
但是当我尝试执行命令时:
/export/home/test/myapp -T "some argument"
myapp 将"some argument" 读取为两个单独的参数。但我只想将"some argument" 读取为一个参数。 当我直接从终端运行此命令时,它执行成功。我尝试了'"some argument"',""some argument"","some\ argument",但对我不起作用。我怎么能把这个论点看成一个论点。
