Struts2温习(10)--文件上传
程序员文章站

...
自接触这么多种技术的上传来看，还是Struts2的上传最好用，虽然之前有篇文章已经总结了几乎我接触到的所有类型的上传，但Struts2方面感觉讲的还是不够细致。
本文就单文件上传和批量文件上传来进行讲解
具体示例
首页上传页面
Html代码
单文件上传的Action
Java代码
多文件上传的Action
Java代码
针对上面两个Action,都得有那么三个属性【上传的文件，文件类型，文件名】，并且开头必须与表单file的name值一样
在Action中添加一个List<File>类型的与页面所有file域同名的属性。private List<File> up;
添加一个以file域名开头，后面跟ContentType的字符串列表属性，这个由Struts2的文件上传拦截器赋文件类型值。如：private List<String> upContentTyp;
添加一个以file域名开头，后面跟FileName的字符串列表属性，这个由Struts2的文件上传拦截器赋文件名的值。如：private List<String> upFileName;
通过IO流循环操作，完成文件的读写。
记住：在struts2的Action中，对于无论是单个文件上传还是批量上传，就是凡是页面上的file文本域的name=xxx的， 那么Action的三个属性必须为xxx,xxxContentType,xxxFileName

token防止重复提交表单【主要是防止上传过后点击浏览器的后退按钮，再次提交这个问题】
1) 在页面的表单中添加<s:token/>
2) 在要使用token的Action配置中添加token或tokenSession拦截器。
看到没有，我们在配置中还配置了<result name="input">/index.jsp</result>，这样的话，如果上传失败就会跳到index.jsp页面，不过现在
我们还没涉到类型限制的问题，接下来，将的就是如何为上传添加文件类型
struts2中为文件上传添加类型限制有两种方式：
第一种方式在Action纯写代码方式
看BatchFileUploadAction中，copy(up.get(i), new File(basePath.getCanonicalPath()+"/" + upFileName.get(i)));这句话，如果将其上边的被注释的段落注释去掉，将本行注释掉，那么就可以起到文件限制，具体可以在isAllowType这个方法中配置
第二种方式在struts.xml中配置
将上边struts.xml中的
Java代码
替换成下面的
Xml代码
上面配置的是上传文件类型的限制，其实共有两个参数
maximumSize (可选) - 这个拦截器允许的上传到action中的文件最大长度(以byte为单位).
注意这个参数和在webwork.properties中定义的属性没有关系,默认2MB
allowedTypes (可选) - 以逗号分割的contentType类型列表(例如text/html),
这些列表是这个拦截器允许的可以传到action中的contentType.如果没有指定就是允许任何上传类型.
那么具体想添加什么类型就可以在这个配置文件中 <interceptor-ref name="fileUpload">的内容里进行自定义了
现在为止，开发中可能用到的类型大致有如下这么多种,也就是mime类型
Java代码
关于office2007的几个常用的mime类型为
.dotx,application/vnd.openxmlformats-officedocument.wordprocessingml.template
.docx,application/vnd.openxmlformats-officedocument.wordprocessingml.document
.xlsx,application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
.pptx,application/vnd.openxmlformats-officedocument.presentationml.presentation
到此，文件类型被限制住了，那么当类型不对时，<result name="input">/index.jsp</result>这个就起作用了，意思
就是凡是上传遇到的类型不是规定类型的文件时，都会跳到index.jsp就是还是上传页面并显示错误信息，错误信息呢是利用了国际化配置在资源文件中的，页面上用 <s:fielderror name="up"></s:fielderror>来显示错误信息
假如我们限制类型为： image/png,image/gif,image/jpeg,text/plain,application/pdf,text/html,application/msword
那么上传的效果为
单独上传
上传后
如果我们不点击返回继续上传，而是点击浏览器上的后退按钮，那么这时TOKEN将起作用，提示下面的页面
如果我们上传一个不在限定类型内的文件的话，也会报错
上传后的结果
对于批量上传

</interceptor-stack>
</interceptors></span></span>
替换成下面的
Xml代码
<span style="font-size: large;"><span style="font-size: large;"> <interceptors>
struts2的defaultStack中已经含有fileupload拦截器，如果想加入allowedTypes参数，
需要从新写一个defaultstack ，拷贝过来修改一下
<interceptor-stack name="myStack">
<interceptor-ref name="exception"/>
<interceptor-ref name="alias"/>
<interceptor-ref name="servletConfig"/>
<interceptor-ref name="i18n"/>
<interceptor-ref name="prepare"/>
<interceptor-ref name="chain"/>
<interceptor-ref name="debugging"/>
<interceptor-ref name="profiling"/>
<interceptor-ref name="scopedModelDriven"/>
<interceptor-ref name="modelDriven"/>
修改下面的这些文件类型值，就可以限制上传文件的类型了
<interceptor-ref name="fileUpload">
<param name="allowedTypes">
image/png,image/gif,image/jpeg,text/plain
</param>
</interceptor-ref>
上面配置的是上传文件类型的限制，其实共有两个参数
maximumSize (可选) - 这个拦截器允许的上传到action中的文件最大长度(以byte为单位).
注意这个参数和在webwork.properties中定义的属性没有关系,默认2MB
allowedTypes (可选) - 以逗号分割的contentType类型列表(例如text/html),
这些列表是这个拦截器允许的可以传到action中的contentType.如果没有指定就是允许任何上传类型.

关于office2007的几个常用的mime类型为
.dotx,application/vnd.openxmlformats-officedocument.wordprocessingml.template
.docx,application/vnd.openxmlformats-officedocument.wordprocessingml.document
.xlsx,application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
.pptx,application/vnd.openxmlformats-officedocument.presentationml.presentation
到此，文件类型被限制住了，那么当类型不对时，<result name="input">/index.jsp</result>这个就起作用了，意思
就是凡是上传遇到的类型不是规定类型的文件时，都会跳到index.jsp就是还是上传页面并显示错误信息，错误信息呢是利用了国际化配置在资源文件中的，页面上用 <s:fielderror name="up"></s:fielderror>来显示错误信息
假如我们限制类型为： image/png,image/gif,image/jpeg,text/plain,application/pdf,text/html,application/msword
那么上传的效果为
单独上传
上传后
如果我们不点击返回继续上传，而是点击浏览器上的后退按钮，那么这时TOKEN将起作用，提示下面的页面
如果我们上传一个不在限定类型内的文件的话，也会报错
上传后的结果
对于批量上传
上传后
