我逗了，忘了加项目名称了

我用Servers启动服务器，然后在src/test/java 创建客户端，Run As-->Java Application客户端，结果报Error writing to server。

用的是DES加解密过滤器

搞了1会儿，原来是web.xml配置了加密过滤器，结果连接不上。
然后我在filter那加了个
<init-param>
<description>不加密的url</description>
<param-name>url</param-name>
<param-value>/ecg/user/report/receive</param-value>
</init-param>
就OK了。此贴终结，顺便问下万能的网友，如果不修改配置，发送端要怎么样才能连接啊？

我把代码简化了下，发送成功.但是接受服务器返回的数据失败。
客户端
public class SendXmlTest {
@Test
public void test() {
try {
URL url = new URL("http://127.0.0.1:8080/wootop-api/ecg/user/report/receive");
HttpURLConnection con = (HttpURLConnection) url.openConnection();
con.setDoOutput(true);
con.setRequestProperty("User-agent", "MSIE8.0"); //设置代理为IE8
con.setRequestMethod("POST");
con.setConnectTimeout(600000);
OutputStreamWriter out = new OutputStreamWriter(con
.getOutputStream());
String xmlInfo = getXmlInfo();
//System.out.println("xmlInfo=" + xmlInfo);
out.write(new String(xmlInfo.getBytes("UTF-8")));
out.flush();
out.close();
//请求成功，返回数据
System.out.println("发送成功！");
BufferedReader br = new BufferedReader(new InputStreamReader(con
.getInputStream()));
String line = "";
for (line = br.readLine(); line != null; line = br.readLine()) {
System.out.println(line);
}
System.out.println("接受成功！");
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
服务端
@RequestMapping("receive")
public String receiveXml(HttpServletRequest request,HttpServletResponse response) {
SAXReader saxReader = null;
Document doc = null;
try{
saxReader = new SAXReader();
doc = saxReader.read(request.getInputStream());
String xmlStr = doc.asXML();
System.out.println("xmlInfo=" + xmlStr);
//ecgUserReportService.saveXmlResult(xmlStr,4127);
return xmlStr ;
} catch (Exception e){
e.printStackTrace();
}
return null ;
}
报错：
发送成功！
