spring中上傳的時候會出現中文的亂碼，還有在前臺有時候繫結引數的時候，往後臺傳遞值得時候也會出現亂碼。解決方案如下。

1.在WEB,XML中配置如下內容

  <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>  

</filter>  

<filter-mapping>  

   <filter-name>Set Character Encoding</filter-name>  

   <url-pattern>/*</url-pattern>  

</filter-mapping> 

2.在JSP頁面進行頁面編碼：(spring-mvc-showcase-master/src/main/webapp/WEB-INF/views/fileupload.jsp)

<%@ page language="java" contentType="text/html; charset=UTF-8"%>

或者 <form action="form_action.asp" accept-charset="UTF-8">

web.xml中配置完如下

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">
  <display-name></display-name>
  <servlet>
    <servlet-name>springmvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:springMVC.xml</param-value>
    </init-param>
  </servlet>
  <servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <url-pattern>*.action</url-pattern>
  </servlet-mapping>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>
