crypto-js des加密与解密 与java运行结果不一致的问题

public byteToString(arr) {
  if(typeof arr === 'string') {

  var str = '',

//加密
public encryptDES(psw:string,key:string){

  var iv = [1,2,3,4,5,6,7,8];
  var ivHex =  CryptoJS.enc.Latin1.parse(this.byteToString(iv));//原java使用的是iv = [1,2,3,4,5,6,7,8]

  var keyHex = CryptoJS.enc.Hex.parse(CryptoJS.enc.Utf8.parse(key).toString(CryptoJS.enc.Hex));

  var encrypted = CryptoJS.DES.encrypt(psw, keyHex,
    { iv: ivHex,
      mode: CryptoJS.mode.CBC,
      padding: CryptoJS.pad.Pkcs7
    }

  return encrypted.toString();
