Java使用TCP协议获取XML及其处理【续】

上一篇文章《Java使用TCP协议获取XML及其处理》（见：http://blog.csdn.net/softwave/article/details/8947771）中，介绍了用Java模拟Socket服务器端，与客户端进行TCP通讯的例子。今天在现场中，客户使用C#制作的服务器端，与我们Java的客户端通讯出现了一个小问题，就是双方发送的XML信息出现乱码现象，客户端向服务器发送的请求信息头出现“/0”等乱字符，服务器端响应给客户端的XML中的中文出现乱码。我们考虑应该是编码不一致造成的问题，统一采用UTF-8编码。所以对上一篇文章中的代码进行了修正。上一篇文章《Java使用TCP协议获取XML及其处理》

protected void onBoReadNoTest() throws Exception {
Socket soc = null;
String data = "";
InetAddress addr = InetAddress.getByName("127.0.0.1");
int serverPort = 1111;
if (addr.isReachable(5000)) {
System.out.println("SUCCESS - ping " + addr
+ " with no interface specified");
try {
soc = new Socket(addr, serverPort);
System.out.println("Socket Success!");
DataInputStream in = new DataInputStream(soc.getInputStream());
DataOutputStream out=new DataOutputStream(soc.getOutputStream());
String str = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><cmd>ReadWeight</cmd>";
byte[] b = str.getBytes();
out.write(b);
byte[] b2 = new byte[1024];
int count = in.read(b2, 0, b2.length);
data = new String(b2,0,count,"UTF-8");
this.DOM(data);
} catch (UnknownHostException e) {
System.out.println("Socket Error:" + e.getMessage());
} catch (EOFException e) {
System.out.println("EOF:" + e.getMessage());
} catch (IOException e) {
System.out.println("IO:" + e.getMessage());
} finally {
if (soc != null)
try {
soc.close();
} catch (IOException e) {/* close failed */
}
}
} else {
System.out.println("FAILURE - ping " + addr
+ " with no interface specified");
}
}

DOM解析如下：

// DOM解析方法
public void DOM(String data) {
long lasting = System.currentTimeMillis();
System.out.println("解析XML开始...........");
try {
byte[] b = data.getBytes("UTF-8");
InputStream inp = new ByteArrayInputStream(b);
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = builder.parse(inp);
NodeList nl = doc.getElementsByTagName("result");
WeightVO wvo = new WeightVO();
for (int i = 0; i < nl.getLength(); i++) {
wvo.setCode(doc.getElementsByTagName("code").item(i).getFirstChild() == null ?null:doc.getElementsByTagName("code").item(i).getFirstChild().getNodeValue());
wvo.setWeight(doc.getElementsByTagName("weight").item(i).getFirstChild()==null? null:doc.getElementsByTagName("weight").item(i).getFirstChild().getNodeValue());
wvo.setErrmsg(doc.getElementsByTagName("errmsg").item(i).getFirstChild() == null ? null : doc.getElementsByTagName("errmsg").item(i).getFirstChild().getNodeValue());
wvo.setUtil(doc.getElementsByTagName("unit").item(i).getFirstChild()==null?null:doc.getElementsByTagName("unit").item(i).getFirstChild().getNodeValue());
}
getBillCardPanelWrapper().getBillCardPanel().getHeadItem("nweight").setValue(wvo.getWeight());
} catch (Exception e) {
e.printStackTrace();
}
// System.out.println("DOM RUNTIME 解析时间："
// + (System.currentTimeMillis() - lasting) + " MS");
}
