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:

接收数据的文件department_update_do.jsp:
<%@ page contentType="text/html" pageEncoding = "GBK"%>
<%@ page import="com.lb.teashop.factory.*" %>
/jsp:useBean
/jsp:setProperty

连锁店信息维护
<% request.setCharacterEncoding("GBK"); //解决中文乱码问题 %>
添加连锁店

<%=department.getId() %>

<%=department.getName() %>

<%=department.getAddress() %>

<%=department.getPhone() %>

<%=department.getFax() %>

<%=department.getApply_page_sn() %>

<%
if(department.isValidate()){
try{
if(DAOFactory.getDepartmentDAOInstance().doUpdateDepartment(department)>0 ){
%>

商品信息修改成功!


<%
response.setHeader("refresh","2;URL=department_list.jsp");
}else{
%>

商品信息修改失败!


<%
response.setHeader("refresh","2;URL=department_add.jsp?id="+department.getId());
}
}catch(Exception e){
e.printStackTrace(); //在Tomcat后台打印
}
}else{
%>
/jsp:forward
<%
//response.setHeader("refresh","2;URL=department_add.jsp");
}
%>

全部的整型变量如果小于10,接收文件看到的都为0,大于等于10的都没问题。求大牛指点迷津!非常感谢!
