SPRINGMVC Micro-Credit Payment callback sample code _java

Introduced

We all know that micro-credit payment callback link requirements cannot be with parameters, but also receive the returned XML data. I started using @RequestBody annotations on parameters, hoping to get XML data, and the test failed. The last use HttpServletRequest to get the data was successful.

Sample code

@RequestMapping ("/weixinpay/callback") public
String callback (HttpServletRequest request) {
 InputStream is = Request.getinputstream ();
 String XML = streamutil.inputstream2string (IS, "UTF-8")
 /**
 * Convert XML to map based on data for logical processing/
}

/**
 * InputStream flow replaced by string string
 * @param instream inputstream Stream
 * @param encoding encoding format
 * @return string literal
 *
/public static string inputstream2string (InputStream instream, string encoding) {
 string result = NULL;
 try {
 if (instream!= null) {
  Bytearrayoutputstream outstream = new Bytearrayoutputstream ();
  byte[] tempbytes = new Byte[_buffer_size];
  int count =-1;
  while ((count = Instream.read (tempbytes, 0, _buffer_size))!=-1) {
    outstream.write (tempbytes, 0, Count);
  }
  Tempbytes = null;
  Outstream.flush ();
  result = new String (Outstream.tobytearray (), encoding);
 }
 catch (Exception e) {result
 = null;
 }
 return result;
}
