用struts向数据库中储存图片
这个例子是通过用Struts的FormFile来写入到MySQL中。。。
用用户通过选一个图片,然后按submit就可以存入数据库中
其中先要建立一个表:
create table test ( name varchar(20), pic blob );在MySQL的test库中
1<%@ page language="java"%>
2<%@ taglib uri="http://jakarta.apache.org/struts/tags-bean" prefix="bean"%>
3<%@ taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html"%>

9 <body>
10 <html:form action="/multi" enctype="multipart/form-data">一定要用enctype=“multipart/form-data“不然就提交之后就会有抛出异常
11 file : <html:file property="file"/><html:errors property="file"/></br>
12 name : <html:text property="name"/><html:errors property="name"/></br>
13 <html:submit/><html:cancel/>
14 </html:form>
