是按照慕课网的教程抄的代码，可是不知道为什么总是报错
Servlet.service() for servlet [weixinServlet] in context with path [/One] threw exception [Servlet execution threw an exception] with root cause
java.lang.NoClassDefFoundError: javax/jms/TextMessage
错误出现在这一行
我把weixinservlet类和checkutil还有messageutil类发在下面了，求大牛指点错在哪里了
↓↓下面是WeixinServlet类的dopost方法
protected void doPost(HttpServletRequest req,HttpServletResponse resp)
throws ServletException,IOException{
req.setCharacterEncoding("UTF-8");
resp.setCharacterEncoding("UTF-8");
PrintWriter out = resp.getWriter();
try {
Map map = MessageUtil.xmlToMap(req);
String fromUserName = map.get("FromUserName");
String toUserName = map.get("ToUserName");
String msgType = map.get("MsgType");
String content = map.get("Content");
String message = null;
if("text".equals(msgType)){
TextMassage text = new TextMassage();
text.setFromUserName(toUserName);
text.setToUserName(fromUserName);
text.setMsgType("text");
text.setContent("您发送的消息是"+content);
message = MessageUtil.textMessageToXml(text);
}
out.print(message);
} catch (DocumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}finally{
out.close();
}
}
↓↓这是checkutil类
package com.tianmg.util;
import java.security.MessageDigest;
import java.util.Arrays;
public class CheckUtil {
public static final String token = "tianmg";
public static boolean checkSignature(String signature,String timestamp,String nonce){
String[] arr=new String[]{token,timestamp,nonce};
Arrays.sort(arr);
StringBuffer content = new StringBuffer();
for(int i = 0;i>> 4 & 0xf];
buf[k++] = hexDigits[byte0 & 0xf];
}
return new String(buf);
} catch (Exception e) {
// TODO: handle exception
return null;
}
}
}
↓↓这是messageutil类
package com.tianmg.util;
import java.io.IOException;
import java.io.InputStream;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import javax.jms.TextMessage;
import javax.servlet.http.HttpServletRequest;
import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;
import com.immoc.po.TextMassage;
import com.thoughtworks.xstream.XStream;
public class MessageUtil {
public static MapxmlToMap(HttpServletRequest request)throws IOException,DocumentException{
Mapmap=new HashMap();
SAXReader reader = new SAXReader();
InputStream ins = request.getInputStream();
Document doc = reader.read(ins);
Element root = doc.getRootElement();
List list = root.elements();
for(Element e:list){
map.put(e.getName(),e.getText());
}
ins.close();
return map;
}
public static String textMessageToXml(TextMassage text){
XStream xstream = new XStream();
xstream.alias("xml", text.getClass());
return xstream.toXML(text);
}
