如何将带有TYPE_INT_ARGB的BufferedImage保存到jpg？

程序生成我的图像:

它没关系,但是当我以这种方式保存它时:

    ByteArrayOutputStream byteStream = new ByteArrayOutputStream();
    BufferedOutputStream bos = new BufferedOutputStream(byteStream);
    try {
        ImageIO.write(buffImg, "jpg", bos);
        // argb
        byteStream.flush();
        byte[] newImage = byteStream.toByteArray();

        OutputStream out = new BufferedOutputStream(new FileOutputStream("D:\\test.jpg"));
        out.write(newImage);
        out.close();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

结果是:

了解这是由于alpha层,但不知道如何解决它.Png格式不适合我,需要jpg.

我有一些XML文件,我想更改名称,如果name == testName.所以我写了这样的东西,但它不起作用.我在哪里做错了？它打印给我参数类型不匹配,我不知道为什么.

String xmlData = "
    <logger>
      <logLevel>
        <id>1</id>
        <idn>id1</idn>
        <name>testName</name>
        <level>warn</level>
        <logLevelsPos>
          <package id="97724539">
            <packName>package1</packName>
          </package>
          <package id="98264591">
            <packName>package2</packName>
          </package>
        </logLevelsPos>
      </logLevel>
      <logLevel>
        <id>2</id>
        <idn>id2</idn>
        <name>nameName</name>
        <level>error</level>
        <logLevelsPos>

          </package>
        </logLevelsPos>
      </logLevel>
    </logger>";

def loggr = new groovy.util.XmlParser().parseText( xmlData );
for (def it : loggr.children()){
    if(it.name.text().equals("testName") ) {
        it.name.value = "ds";
        //argument type mismatch ...
    }
