java执行cmd命令并获取输出结果

1.java执行cmd命令并获取输出结果

import java.io.BufferedReader;
import java.io.InputStreamReader;

import org.apache.commons.lang3.text.StrBuilder;

/**

 */
public class DeleteProgram {
    public static void run() {
        Runtime runtime = Runtime.getRuntime();
        try {
            BufferedReader br = new BufferedReader(new InputStreamReader(runtime.exec("ipconfig").getInputStream()));
            //StringBuffer b = new StringBuffer();
            String line=null;
            StringBuffer b=new StringBuffer();
            while ((line=br.readLine())!=null) {
                b.append(line+"\n");
            }
            System.out.println(b.toString());
        } catch (Exception e) {
            e.printStackTrace();
        }

    }

    public static void main(String[] args) {
        DeleteProgram delp = new DeleteProgram();
        delp.run();
    }

}

2.获取您需要的字段

public static String getbackage(String path){
     Process p;  
        //test.bat中的命令是ipconfig/all 
        String cmd = "aapt dump badging " + path;
//        String cmd="jarsigner -verify -verbose -certs C:\\Users\\Administrator\\Desktop\\PandaClient.apk";  
        String resultstr = null;
        try  
        {  
            //执行命令  
            p = Runtime.getRuntime().exec(cmd);  
            //取得命令结果的输出流  
            InputStream fis=p.getInputStream();  
            //用一个读输出流类去读  
            //用缓冲器读行  
            BufferedReader br=new BufferedReader( new InputStreamReader(fis,"GB2312"));  
            String line=null;  
            //直到读完为止  
            int i = 0;
            while((line=br.readLine())!=null)  
            {  
             if(line.contains("package:")){  //解析符合自己需要的內容，获取之后，直接返回。
                
              resultstr = line;
                  break;
             }
//                resultstr=line;
                i++;
            }  
        }  
        catch (IOException e)  
        {  
            e.printStackTrace();  
        }  
        return resultstr;
}

    public static void main(String[] args) {
        String url="www.taobao.com";
        String response=null;
        response=getSingle(url);
        
        System.out.println(response);
    }
