报错的地方
- Java code

我的代码：
- Java code
String dType = request.getParameter("dType"); String dIpAdd = request.getParameter("dIpAdd"); int dPort = Integer.parseInt(request.getParameter("dPort")); String dDescription = request.getParameter("dDescription"); String dUsrName = request.getParameter("dUsrName"); String dUsrPwd = request.getParameter("dUsrPwd"); int videoChannels = Integer.parseInt(request.getParameter("videoChannels")); String vch1 = request.getParameter("vch1"); String vch2 = request.getParameter("vch2");这个错误貌似是说数据转换问题，或者是其他问题，纠结了好长时间，也baidu了好长时间，不知道怎么解决？求帮助~~~
------解决方案--------------------------------------------------------
Integer.parseInt之前先打印一下变量不就知道了
------解决方案--------------------------------------------------------
错误在你的 EditManagementServlet.java:66行 ，数据类型错误，java.lang.NumberFormatException: For input string: "on" 你贴的代码里没有66行
------解决方案--------------------------------------------------------
是不是String类型转成int型的转错了啊
换种方式转试试
Integer intObj = new Integer(user.getWorkendtime());
int inte = intObj.intValue();
------解决方案--------------------------------------------------------
java.lang.NumberFormatException: For input string: "on"
at java.lang.NumberFormatException.forInputString(Unknown Source)
at java.lang.Integer.parseInt(Unknown Source)
at com.bellsent.servlet.EditManagementServlet.doPost(EditManagementServlet.java:66)
int dPort = Integer.parseInt(request.getParameter("dPort"));
request.getParameter("dPort") 这个值应该为 "on"了，不能转换
