[code]上传下载ssh和jsp+servlet (组件是fileupload)

遇到错误：
1.
fileupload取编辑框的值乱码。
String value = item.getString();
改为
String value = item.getString("UTF-8");

2.

原因是因为mysql在建表时是用intan1编码的（就算建表后改成utf-8）也不行~~~
要删表，再重新建表才行。

3.

Do you have this setting in your form?
enctype="multipart/form-data"
无设form的编码

依赖注入无setter方法~~

5.
javax.servlet.ServletException: javax.servlet.jsp.JspException: Cannot retrieve definition for form bean null on action /goselect.do
org.apache.jasper.runtime.PageContextImpl.doHandlePageException(PageContextImpl.java:850)

action无配formbean
action要指定相关的form bean

6.
javax.servlet.ServletException: No getter method for property file1 of bean

<form>标签中的file1在frombean中无对应的file1属性

心得：
1
在struts中jsp的<from>要对应formbean的属性~~~~~
两者的名称很重要~~~~
如果不对应就会提示，很多这些那些的设置属性错误~~~~

file_0:false
file[0]:true

System.out.println("file[0]:"+elements.containsKey("file[0]"));
FileinfosForm f = (FileinfosForm) form;

file[0]:true
file.gif
