Spring获取公众号xml数据的两种方式
方式1：HttpServletRequest req
@PostMapping(produces = "application/xml; charset=UTF-8")
public String post(HTTPServletRequest req,
@RequestParam("signature") String signature,
@RequestParam("timestamp") String timestamp,
@RequestParam("nonce") String nonce,
@RequestParam("openid") String openid,
@RequestParam(name = "encrypt_type", required = false) String encType,
@RequestParam(name = "msg_signature", required = false) String msgSignature) {
logger.info("notifyData"+requestData,requestData.toString());
logger.info("post:{},{},{},{},{}",signature,timestamp,nonce,openid,encType,msgSignature);
if (!CheckUtil.checkSignature(signature, timestamp, nonce)) {
throw new IllegalArgumentException("非法请求！");
}
Map map = null;
try {
map = MessageUtil.xmlToMap(req);
wxAccountService.router(map,openid);
System.out.println(openid);
} catch (Exception e) {
e.printStackTrace();
}
return "";
}
方式2：@RequestBody
requestData任意命名，即可把body中的xml数据转换为xml字符串。
@PostMapping(produces = "application/xml; charset=UTF-8")
public String post(@RequestBody String requestData,
@RequestParam("signature") String signature,
@RequestParam("timestamp") String timestamp,
@RequestParam("nonce") String nonce,
@RequestParam("openid") String openid,
@RequestParam(name = "encrypt_type", required = false) String encType,
@RequestParam(name = "msg_signature", required = false) String msgSignature) {
logger.info("notifyData"+requestData,requestData.toString());
logger.info("post:{},{},{},{},{}",signature,timestamp,nonce,openid,encType,msgSignature);
if (!CheckUtil.checkSignature(signature, timestamp, nonce)) {
throw new IllegalArgumentException("非法请求！");
}
Map map = null;
try {
map = WXPayUtil.xmlToMap(requestData);
// map = MessageUtil.xmlToMap(req);
wxAccountService.router(map,openid);
System.out.println(openid);
} catch (Exception e) {
e.printStackTrace();
}
return "";
}

public static Map xmlToMap(String strXML) throws Exception {
try {
Map data = new HashMap();
DocumentBuilder documentBuilder = WXPayXmlUtil.newDocumentBuilder();
InputStream stream = new ByteArrayInputStream(strXML.getBytes("UTF-8"));
org.w3c.dom.Document doc = documentBuilder.parse(stream);
doc.getDocumentElement().normalize();
NodeList nodeList = doc.getDocumentElement().getChildNodes();
for (int idx = 0; idx < nodeList.getLength(); ++idx) {
Node node = nodeList.item(idx);
if (node.getNodeType() == Node.ELEMENT_NODE) {
org.w3c.dom.Element element = (org.w3c.dom.Element) node;
data.put(element.getNodeName(), element.getTextContent());
}
}
try {
stream.close();
} catch (Exception ex) {
// do nothing
}
return data;
} catch (Exception ex) {
WXPayUtil.getLogger().warn("Invalid XML, can not convert to map. Error message: {}. XML content: {}", ex.getMessage(), strXML);
throw ex;
}
}
* 利用dom4j读取xml文件存放在map对象中

SAXReader reader = new SAXReader();
InputStream ins = request.getInputStream();
Document doc = reader.read(ins);
Element root = doc.getRootElement();
