The example of this article shares the specific code for decrypting Java Weixin Official Accounts security mode messages for your reference. The specific contents are as follows

1. WeChat public platform download decryption tool, import project, according to demo decryption message, decryption tool official download address: click open link

public static String streamToString(HttpServletRequest request) throws IOException { BufferedReader reader = new BufferedReader(new InputStreamReader(request.getInputStream())); StringBuilder sb = new StringBuilder(); String line; try { while ((line = reader.readLine()) != null) { sb.append(line); } } catch (IOException e) { e.printStackTrace(); } return sb.toString(); } /** * xml to map collection * * @param request * @param msg * @return * @throws IOException * @throws DocumentException */ public static Map xmlToMap (HttpServletRequest request, Message msg) throws Exception { SAXReader reader = new SAXReader(); String token = ""; String encodingAesKey = ""; String appId = "";//Get encrypted message xml string/* String format = ""; Document document = reader.read (request.getInputStream()); Element rootElement = document.getRootElement(); Element encrypt = rootElement.element("Encrypt");*// String fromXML = String.format(format, encrypt.getText()); String fromXML = streamToString(request);//decrypt the message WXBizMsgCrypt pc = new WXBizMsgCrypt(token, encodingAesKey, appId); //obtain the decrypted message String result = pc.decryptMsg(msg.getMsg_signature(), msg.getTimestamp(), msg.getNonce(), fromXML); Map map = new HashMap(6); //convert the decrypted message to xml Document doc = DocumentHelper.parseText(result); Element root = doc.getRootElement(); List list = root.elements(); for (Element e : list) { map.put(e.getName(), e.getText()); } return map; }

Message Entity Class

package com.caisin.weixin.domain; import lombok.Data; @Datapublic class Message { private String signature; private String timestamp; private String nonce; private String openid; private String msg_signature; private String encrypt_type;}
