问题描述
- JSP用JAVABEAN传整型值时，如果数值为一位，接收到的值为0，两位以上的值正常。
-
现象如题，环境为MYECLIPSE和TOMCAT6，代码如下：
提交数据的文件department_add.jsp：
<%@ page contentType="text/html" pageEncoding = "GBK"%>
<%@ page import="com.lb.teashop.factory.*,com.lb.teashop.vo.*"%>连锁店信息维护
<% request.setCharacterEncoding("GBK"); //解决中文乱码问题 %>添加连锁店
<%
String id = request.getParameter("id");
if(!(null == id || "".equals(id))){ //指定code时，显示对应信息
try{
DepartmentBean dpt=DAOFactory.getDepartmentDAOInstance().findDepartmentById(Integer.parseInt(id));
//out.println("dgc_code:" + dpt.getName());
department = dpt;
//out.println("department_id:" + department.getId());
%>
店名：
<%=department.getAddress()%><%=department.getErrorMsg("errAddress")%>
电话： <%
}catch(Exception e){
e.printStackTrace();
}
}else{ //未指定code时，显示空白录入界面。
%>
连锁店名称： <%=department.getErrorMsg("errName")%>
拼音码： <%=department.getErrorMsg("errPy_code")%>
地址： <%=department.getErrorMsg("errPy_code")%>
电话： <%=department.getErrorMsg("errPhone")%>
传真： <%=department.getErrorMsg("errFax")%>
<%
}
%>JAVABEAN文件DepartmentBean.java：
