【8】测试结果：
打印日志：
测试输入：
图7
修改成功后，跳转供应商信息展示：
图8
文件上传成功：
图9
【0】功能描述：
供应商修改与保存功能：（1）登陆成功后（login.jsp），sys.jsp 系统页面会有链接---“供应商修改”，点击跳转到补全供应商修改信息（ providerModifySave.jsp），若是添加成功则会保存至数据库，并跳转供应商显示（providerlist.jsp），否则继续返回系统页面（sys.jsp）；（2）供应商修改信息包括常用数据和文件上传；【1】jar包/文件架构
jar包：图1
文件结构：
图2
【2】数据库准备：
已经新建了smbms_provider表，并新增了几个记录，可以参考《SpringMVC（18）：使用springmvc+spring+jdbc优化订单管理系统的示例（供应商新增的功能实现）》：
图3
图4
【3】View层：
1.在sys.jsp添加以下代码：<h4>------------------点击下面的链接进行供应商信息修改：---------</h4>
<br>
<a href="${pageContext.request.contextPath}/usera/providerModify.html">跳转到供应商信息修改.</a>
<br/>效果：
图5
2.新建/jsp/providerModifySave.jsp：
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

</head>
<body>
<h5>这是providerModifySave页面！</h5>
<form action="${pageContext.request.contextPath }/usera/providerModifySave.html" method="post" enctype="multipart/form-data">
需要修改信息的供应商ID：<input type="text" name="id" value=""><br>
