这篇文章主要为大家详细介绍了Java微信公众号安全模式消息解密，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
 1.微信公众平台下载解密工具,导入项目中,根据demo解密消息
                      PE="button" class="copyCode code-tool" data-toggle="tooltip" data-placement="top" data-clipboard-text="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转为map集合   *   * @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 = "";   //获取加密消息xml字符串   /* String format = "toUser%1$s";   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);   //解密消息   WXBizMsgCrypt pc = new WXBizMsgCrypt(token, encodingAesKey, appId);   //获得解密消息   String result = pc.decryptMsg(msg.getMsg_signature(), msg.getTimestamp(), msg.getNonce(), fromXML);   Map map = new HashMap@H_512_17@(6);   //将解密后的消息转为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;  }" tITle="" data-original-title="复制">       
       
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转为map集合   *   * @param request   * @param msg   * @return   * @throws IOException   * @throws DocumentException   */  public static Map<String, String> xmlToMap(HttpServletRequest request, Message msg) throws Exception {   SAXReader reader = new SAXReader();   String token = "";   String encodingAesKey = "";   String appId = "";   //获取加密消息xml字符串   /* String format = "<xml><ToUserName><![CDATA[toUser]]></ToUserName><Encrypt><![CDATA[%1$s]]></Encrypt></xml>";   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);   //解密消息   WXBizMsgCrypt pc = new WXBizMsgCrypt(token, encodingAesKey, appId);   //获得解密消息   String result = pc.decryptMsg(msg.getMsg_signature(), msg.getTimestamp(), msg.getNonce(), fromXML);   Map<String, String> map = new HashMap<>(6);   //将解密后的消息转为xml   Document doc = DocumentHelper.parseText(result);   Element root = doc.getRootElement();   List<Element> list = root.elements();   for (Element e : list) {    map.put(e.getName(), e.getText());   }   return map;  }
 Message实体类
                             
       
package com.caisin.weixin.domain; import lombok.Data; @Data public class Message {  private String signature;  private String timestamp;  private String nonce;  private String openid;  private String msg_signature;  private String encrypt_type; }
 2.将JDK中 jdkjrelibsecuritypolicyunlimited目录中local_policy.jar和US_export_policy.jar两个文件拷贝到 jdkjrelibsecurity目录下
