配置環(huán)境
1.JSP文件
<form action="/fileupload" method="post" enctype="multipart/form-data">
姓名:<input type="text" name="name" /> <br/>
年齡:<input type="text" name="age" /> <br/>
<input type="file" name="uploadfile" accept="image/*"/> <br/>
<input type="submit" value="提交"/>
</form>
//1.post.
//2.enctype="multipart/form-data"
//3.選擇文件按鈕配置file ,accept="image/*";
2.導(dǎo)包
1.commons-fileupload-1.2.2.jar
2.commons-io-1.4.jar
如果io包沒有導(dǎo)入,則會(huì)報(bào)以下錯(cuò)誤
java.lang.ClassNotFoundException: org.apache.commons.io.output.DeferredFileOutputStream
