下面是我在服务中封装的方法
private void invokeCommand(final HttpExchange httpExchange) {
logger.info("invoke command service start!");
String requestBody = IOUtil.readStream(httpExchange.getRequestBody());
CommandDefinition command = JSON.parseObject(requestBody, CommandDefinition.class);
Assert.checkNonNull(command);
Assert.check(StringUtils.isBlank(command.getCommand()), "command is null");
Assert.check(StringUtils.isBlank(command.getDir()), "dir is null");
logger.info("invoke command request body:{}", JSONObject.toJSONString(command));
String result = executeCommand(command);
logger.info("invoke command result:{}", result);
}private String executeCommand(CommandDefinition command) {
try {
File dirTmp = new File(command.getDir());
Process process = Runtime.getRuntime().exec(command.getDir(), command.getEnvp(), dirTmp);
BufferedReader input = new BufferedReader(new InputStreamReader(process.getInputStream()));
StringBuilder result = new StringBuilder();
String line;
while ((line = input.readLine()) != null) {
result.append(line);
result.append("\n");
}
input.close();
return result.toString();
} catch (Exception e) {
e.printStackTrace();
return "invoke error!";
}
}【Java调用shell脚本】

如果需要的话只需要关注executeCommand这个方法就可以了
