要先安装nodejs和svgo 

安装好nodejs后在cmd里面输入npm i svgo -g（liunx下直接输入）

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

        String command = "cmd /c svgo d:/dwg/a.svg"; //windows

//        String command = "ping baidu.com -t";
//        String command = "cmd /c node -v";
        Process process = Runtime.getRuntime().exec(command);
        BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream()));
        String line;
        while ((line = br.readLine()) != null) {
            System.out.println(line);
        }
        process.waitFor();
        System.out.println ("exit: " + process.exitValue());
        process.destroy();
    }
