nodejs 中调用 Java 程序的最简单的例子

gistfile1.txt

var spawn = require('child_process').spawn;

var cmds = [["/c","dir"],["/c","java"],["/c","java","-jar"]]

// cmds.forEach(function(v){
//     v && exe(v);
// });

//YUI compressor jar file folder
var ori = __dirname+"/../tools";

// convert posix-style path to dos-style path
var toolPath = posix2dos(ori);

// absolute path of yuicompressor.jar
var Ycompressor = toolPath+"\\yuicompressor.jar";

exe(["/c","java","-jar",Ycompressor,"test.js"]);

function exe(command){
    
    var cmd = spawn("cmd",command);

    cmd.stdout.setEncoding("ASCII");
    cmd.stdout.on("data",function(data){
	console.log("------------------------------");
	console.log("exec",command);
	console.log("stdout:"+data);
    });

    cmd.stderr.on("data",function(data){
	console.log("------------------------------");
	console.log("stderr:"+data);
	console.log("------------------------------");
    });

    cmd.on("exit",function(code){
	console.log("exited with code:"+code);
	console.log("------------------------------");
    });
    
};
function posix2dos(path){
    /*
      /cygdrive/d/att -> d:\\att
     */
    var re = new RegExp(/^\/cygdrive\/(\w)/);

    path = path.replace(re,function(match,drive){
	//console.log(drive);
	return drive+":";
    }).replace(/\//g,'\\');
    return path;
}
