java 程序中调用bat文件的方法代码？
import java.io.BufferedReader;
import java.io.InputStreamReader;
public class RunBat {
public static void main(String[] args) {
try {
Process process = Runtime.getRuntime().exec("D:\\run.bat");
BufferedReader read = new BufferedReader(new InputStreamReader(process.getInputStream()));
String str = null;
while ((str = read.readLine()) != null) {
System.out.println(str);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
java执行bat文件问题
Process process=
Runtime.getRuntime().exec("cmd /c run.bat");//要执行的文件的路径为run.bat
// 得到输入流
InputStream inputStream=process.getInputStream();
InputStreamReader inputStreamReader=new InputStreamReader(inputStream);
BufferedReader bufferedReader=new BufferedReader(inputStreamReader);
// 得到输出流
OutputStream outputStream=process.getOutputStream();
OutputStreamWriter outputStreamWriter=new OutputStreamWriter(outputStream);
BufferedWriter bufferedWriter=new BufferedWriter(outputStreamWriter);
bufferedWriter.write("dd\n");
bufferedWriter.flush();
String temp=null;
while((temp=bufferedReader.readLine())!=null)
{
System.out.println(temp);
}
}
java调用bat，卡死在某一步
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
public class Test {
public static void main(String[] args) throws IOException {
Process p = Runtime.getRuntime().exec("cmd /c D:\\a.bat");
InputStream fis = p.getInputStream();
final BufferedReader br2 = new BufferedReader(new InputStreamReader(p.getErrorStream()));
InputStreamReader isr = new InputStreamReader(fis);
final BufferedReader br = new BufferedReader(isr);
Thread t1 = new Thread(){
public void run(){
String line = null;
try {
while ((line = br2.readLine()) != null) {
System.out.println(line);
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
};
Thread t2 = new Thread(){
public void run(){
String line = null;
try {
while ((line = br.readLine()) != null) {
System.out.println(line);
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
};
t1.start();
t2.start();
}
}
这样写就没问题了，API里有写：Because some native platforms only provide limited buffer size for standard input and output streams, failure to promptly write the input stream or read the output stream of the subprocess may cause the subprocess to block, and even deadlock.因为本地进程输入输出缓存有限，找不到TaReport会导致stderr输出，你不快点读取的话Process就挂在那了。
下面是输出 ：

怎么在java中运行bat命令
@echo off
echo 正在加密，请稍后....
echo path:%~dp0
set base=%~dp0
set class=%base%\bin
set libs=%base%\lib
set
class_path=%class%;%libs%\c3p0-0.9.1.2.jar;%libs%\mysql-connector-java-5.0.8-bin.jar;
java -classpath %class_path% com.test.Main
@pause
文件结构图：
classes目录是java编译后的class目录
libs目录存放的所要使用到的jar
startNet.bat为我们启动的bat文件
