JAVA call Shell Script

在JAVA中调用`Shell`，源于小米开源SQL优化工具[SOAR](https://github.com/XiaoMi/soar)，具体工具使用方法可以直接在[GitHub](https://github.com/XiaoMi/soar)上查看。但是该工具没有界面，于是想通过前端界面发送sql到后台，由后台调用shell脚本来执行。

public void testShell(){
        try {
            Runtime runtime = Runtime.getRuntime();
            Process process = runtime.exec("/Users/alwynxu/Desktop/jmx-demo/test.sh");
//            Process process = runtime.exec("java");
            process.waitFor();
            InputStream inputStream = process.getInputStream();
            InputStream errorStream = process.getErrorStream();

            byte[] errBytes = new byte[1024];
            byte[] inputBytes = new byte[2014];
            int errCount = 0;
            int inputCount = 0;
            System.out.println("执行错误命令：--------");
            while ((errCount = errorStream.read(errBytes)) != -1){
                String str = new String(errBytes,0, errCount);
                System.out.println(str);
            }

            System.out.println("执行结果：----------");
            while ((inputCount = inputStream.read(inputBytes)) != -1){
                String str = new String(inputBytes, 0, inputCount);
                System.out.println(str);
            }

        } catch (IOException e) {
            e.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
