springmvc图片上传遇到的问题(除了图片还要传文字)乱码参数取不到

来源：互联网发布：转区软件vnr 编辑：程序博客网时间：2024/06/05 01:05

一开始因为

<form action="/lvban/food/insertFood.htm" id="uploadForm" method="post"  enctype="multipart/form-data">

表单提交的是二进制所以request.getparameter()取不到值，好百度下发现如下可行

request.setCharacterEncoding("UTF-8");DiskFileItemFactory factory = new DiskFileItemFactory();ServletFileUpload upload = new ServletFileUpload(factory);upload.setHeaderEncoding("UTF-8");List items = null;items = upload.parseRequest(request);Iterator itrTwo = items.iterator();String title = "";String city = "";String address = "";String price = "";String date = "";String oneword = "";while (itrTwo.hasNext()) {FileItem item = (FileItem) itrTwo.next();if (item.isFormField()) {if (item.getFieldName().equals("title")) {title = new String(item.getString().getBytes("iso8859-1"), "utf-8");}else if(item.getFieldName().equals("cmbCity")){city = new String(item.getString().getBytes("iso8859-1"), "utf-8");}else if(item.getFieldName().equals("address")){address = new String(item.getString().getBytes("iso8859-1"), "utf-8");}else if(item.getFieldName().equals("price")){price = new String(item.getString().getBytes("iso8859-1"), "utf-8");}else if(item.getFieldName().equals("date")){date = new String(item.getString().getBytes("iso8859-1"), "utf-8");}else if(item.getFieldName().equals("oneword")){oneword = new String(item.getString().getBytes("iso8859-1"), "utf-8");}}}

高兴一阵，因为有事没有接着把图片上传做了，晚上回来接着做

结果gg。用spring mvc注解上传的方式各种不行，

一开始报The request sent by the client was syntactically incorrect这个错，以为参数有问题，名字该来该去，控制器接受的类型也改来改去

呵呵最后摸索了一阵发现原来配置文件少了一个bean类

<bean id="multipartResolver"class="org.springframework.web.multipart.commons.CommonsMultipartResolver"/>

spring mvc配置文件上传的类

好了以为可以，然并卵，原来的需要传文字的其他参数都取不到值了..各种爆炸

然后认怂，用spring mvc绑定对象参数的方式，苦难缺还没有结束

乱码，烦的一笔，照着百度在web.xml加了如下代码

<filter><filter-name>Set Character Encoding</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>UTF-8</param-value></init-param><init-param><param-name>forceEncoding</param-name><param-value>true</param-value></init-param></filter><filter-mapping><filter-name>Set Character Encoding</filter-name><url-pattern>/*</url-pattern></filter-mapping>

结果还不行，debug了一下，发现后台接收已经没问题数据库问题然后加了这个?nuseUnicode=true&characterEncoding=UTF-8终于搞定

还是水平太差
