用特殊字符形成字符编码问题

问题描述

我设置了这样的内容类型：

 <％@ page language =javacontentType =text / html; charset = ISO-8859-1pageEncoding =ISO-8859-1％> 
  

当我发送像áéíóú这样的特殊字符时，它们可以正确保存在数据库中。我的表格字符集是utf-8。

我想像这样将iso-8859更改为utf-8来标准化我的应用程序并接受更多的特殊字符：

 <％@ page language =javacontentType =text / html; charset = UTF-8pageEncoding =UTF-8 ％GT; 
  

但是当我将其更改为utf-8时，特殊字符áéíóú未正确保存在数据库中。当我尝试保存á时，它被保存为áÃÃÃÃÃÃÃ>>>>>>>>在服务器端我使用的是Spring MVC。我得到这样的文本字段值：

  String strField = ServletRequestUtils.getStringParameter（request，
field ）; 
  

解决方案

当您的网页不是 ISO-8859-1 ，您需要声明一个： p>

 < filter> 
< filter-name> charsetFilter< / 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> charsetFilter< / filter-name> 
< url-pattern> / *< / url-pattern> 
< / filter-mapping> 
  

Hello I have a jsp with an html form.

I set the content type like this:

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1" %>

When I send special characters like á é í ó ú they are saved correctly in the database. My table charset is utf-8.

I want to change iso-8859 to utf-8 like this to standardize my application and accept more special characters:

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

but when I change it to utf-8 the special characters á é í ó ú are not saved correctly in the databse. When I try to save á it is saved as á

In the server side I'm using Spring MVC. I'm getting the text field value like this:

String strField = ServletRequestUtils.getStringParameter(request,
                    "field");

解决方案

When your pages are not ISO-8859-1, you need to declare a CharacterEncodingFilter in web.xml:

<filter>
    <filter-name>charsetFilter</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>charsetFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
