HttpClient post 方式传递方式 及中文乱码解决

public String execute(String xml,HashMap<String, String> dataMap) throws Exception {
HttpClient client = new HttpClient();
client.setStrictMode(false);
client.setTimeout(30000);
PostMethod post = null;
try {
String abc_order_qry_rul = ".....servlet" ;
post = new PostMethod(abc_order_qry_rul);
post.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET, "UTF-8"); //解决乱码
post.addParameter("reqXML", xml);

int statusCode = getHttpClient(30000).executeMethod(post);
if (statusCode != -1) {
return post.getResponseBodyAsString();
} else {
return "状态码---" + statusCode + "---error ...";
}
} catch (Exception e) {
throw e;
} finally {
post.releaseConnection();
}
}

public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("UTF-8");//解决乱码
String reqXml = request.getParameter("reqXML");
String response = getResponse();
OutputStream os = response.getOutputStream();
os.write(respXml.getBytes("UTF-8"));//解决乱码
os.flush();
os.close();
}
